I am planning on hooking a mag 12 up to my laptop to play some music. Right now all I have is the sub and an enclosure for it. As far as plate amps go I am trying to find something that will give me around 1000 rms. The best plate amp I could find at partsexpress is rated at about 1024rms but I heard I would only be getting around 700 out of it. The mag 12 is dvc at 2 ohms. If you have any great ideas on how I can find a better plate amp for around $300-$400 let me know. Then I will just need a little help getting the right things to connect the sub to the plate amp, and the plate amp to my computer since I have never worked with anything but car audio before.

Any particular reason that it has to be a plate amp?

Behringer EP1500....1400w RMS @ 4ohms bridged for $75 less than the sale price on that 1000w plate amp ($150 less than regular price). Plus it's more powerful than that plate amp.

Oh yeah...I'm not extremely computer savvy...but I believe most soundcard outputs are 1/8" mini jacks. So then you'd just need a mini-jack to RCA wire, and then connect that to the inputs of the amplifier.

Something like this (http://cgi.ebay.com/3-5mm-1-8-Y-adapter-stereo-mini-plug-to-female-RCA-jack_W0QQitemZ5868002741QQcategoryZ32833QQssPageNa meZWDVWQQrdZ1QQcmdZViewItem), then connect the inputs on the amplifier to these outputs via regular ole RCA.

That is my next question hahaha..

What should i run for 80hz and up and what should i power it with?

Thanks for showing me that other option. It looks better than the plate amp i was looking at. I really appreciate it.

I know nothing about hooking it up to computers either. That is why I have so many noob questions.

That would be awesome if all i needed was the one cable and some speaker wire.

Also, the mag 12 is dual 2 ohm vc's. So i think with that amp I would have to do a combination of series and parallel wiring. That is perfectly fine.

I just wanted to get that out there in case anyone finds any better amps and was wondering what the vc config was on the mags.

What kind of a budget are you dealing with here? That's basically going to determine the best route to go :)

If you are only hooking up 1 mag then you wouldnt need to do a combination of series / parallel... it would just be series.

DVC 2 ohm = 4 ohms in series....

that amp does 1400 rms @ 4 ohms... which would be great for your mag...

oops...I think i was looking at the wrong wiring diagram.

As for budget. I am looking to spend no more than a couple hundred on the amp and a couple hundred on the speakers.

Well all I have now is my computer, a mag 12 (dvc 2 ohms), and I will most likely pick up that amp squeaky suggested above. I will then get that audio jack to rca outputs and that should hook up to the amp. Then I think I will just need to wire the amp to the sub like a normal car audio one.

What I need now are a couple of full range speakers possible and an amp to power them. Also, i will need to figure out how to hook the speaker amp up to my computer. Not sure how that will work. I don't know much at all about home audio speakers. So I am open to any suggestions. I am hoping to get 2 full range speakers for around 200 and an amp for 150-200 range. Just anywhere close to that price range would be nice.

As for enclosures I will either build them myself or get someone to build them for me. It all depends on if I have the time to do it myself or not. If anyone wants to build an enclosure for me in exchange for some type of deal let me know. I would be willing to work something out.

I hope that is all the info you need.

The JBL Northridge E series has some decent speakers that are pretty inexpensive around the $200 buck mark other wise you could try to look on eBay for stuff, or build your own. But keeping the price around $200 can get hard especially if you build your own. Ascendant Audio has some good Home Audio stuff out now if you are interested in building your own and the R&D department for GG Audio (LOL inside joke) is currently designing and testing a Home Theater main that will be close to the $250 ish mark. Now this part is going to get complicated. If you run out of your computer directly you only have 2 channels Left and Right, so if you "Y" both channels together for a sub then you pollute the Left Right separation for the highs and now have a mono system. Or you could only Y one channel and run the risk of some low end being in stereo and only getting one channel. Plus using that amp you are going to need some sort of Active Crossover to reduce the high end. You are prolly going to need to get some type of pre-amp or active cross over system do to this up right before all is said and done. The best way to think of how to do a system is linearly from point A to point B. So, you are driving the system with your computer, which has 2 outputs L&R. They will run into your high amp for your left and right. Easy no problem there, but now you want to hook up the sub. You hook the left and right together since you only have one sub and one sub amp (which you would still do even if you had more than one sub) and now you have a problem. By simply Ying them together you now crossed the L&R together, so you can’t do that unless you are happy with mono-stereo (mono out of 2 speakers). So, you could use a splitter, an active cross-over, or a pre-amp to solve this problem. If you used the Splitter you would still need to get something to cross over the frequency for the sub, and the splitter would have to be 2 channels. With the active cross-over you would need a 2 channel unit, then y the 2 outputs together for the input of the sub amp. Or you could find a decent but cheap receiver with a pre-out for the sub use that to drive the sub amp and use the amp in the receiver to drive the main stereo channels. I don’t know if this helps but I think it makes it easier if you look at the whole system and try to figure out the best and cheapest way to make it work…

Wow...I am pretty sure I followed all of that. So would you suggest getting a cheap reciever or doing all of the stuff you said? I have no idea how much all these xovers will be and splitters I may need. This home theater stuff is much more complicated than car audio.

Any of the Yamaha's from the RX-V series which you can find online sometimes very cheap. Marantz builds very good ones too, and some of the Denons are ok. The Yamaha's have a lot of nice settings plus they will decode anything you throw at them, and they sound good and clean.

If you are looking for a cost effective, DIY speaker setup, I would consider these two;

http://speakerbuilder.net/web_files/Projects/D3/dayton3.htm

http://www.wadsnet.com/~dtenney/dayton_8MTM.htm


Both are good performers, and pretty popular in the DIY realm. Neither are going to provide absolutely stellar, top tier performance, high end performance....but for a beginner project, they'll perform really wonderfully and really give you a chance to learn a bit in the process. Plus they are very easy on the wallet and they give you a full parts list of what you'll need.

I would like to build something like that. I wouldn't mind doing it. But both of those have subs in those. I am just looking for speakers in the 80-20000 hz range. I already got the sub taken car of. Let me know if you know of any cheap diy projects that just have the highs and not bass too since I doubt I would be able to even hear it anyways.

I will send him a pm. I wish there was just a clear easy answer as to what to do. Right now the mag 12, the mag enclosure, and the mag amp is easy.

The speakers, reciever (if neccesary) and speaker enclosure are up in the air. So is the amp for the speakers in case i don't get a reciever. I think i want to go with a reciever though.

So lets say i get one of those yamaha recievers. Which speaker system here would work best with it?

I just read everything and am going to go for it. I have never done anything like this before and hopefully I won't mess it up. My only concern is that the midbass seems to be tuned to around 37 hz. My mag will be playing all the bass notes so I am not sure if the midbass woofers are neccesary. I think I do need them to play between 80-2000hz probably and I am guessing the sild dome tweeter will play 2000hz-20,000hz. Is it bad to have a overlap between my sub and my midbass woofers?

Also, building this xover is going to be an experiance:crazy:

I haven't read schematics in awhile.

Thanks for all the help. It will take me awhile to get all the parts and build this but it should sound nice. Also, will 1 be enough? Or should I build two of these towers? And if i build something like this do i still need the reciever? or can i just get an amp to power this and hook it up to my computer like i originally planned. I thought what someone was saying was that I needed to build xovers if i wasn't going to buy a reciever. Since i am building them now maybe i won't need the reciever.

I am thinking a reciever would be about the same price as an amp. I just hope i get the same amount of power from a reciever as i wil get from buying just an amp. I got to look up the specs on the speakers to see which reciever would be best. Any one of the yamaha's i listed would probably work fine. I am leaning towards the reciever as long as i don't have to sacrifice any power for other features such as reading cd's and such.

The Yamaha Recievers have a adjustable cross over point for the sub output, which means you can play around with where it over laps and find the sweet spot. With my DM330i's I ran it at about 120Hz now with the 703's it's down to 110Hz, BTW I run an EQ in line with my sub to tune the lowend better...

When I mentioned seperates, I'm talking about a seperate preamplifier and power amp, as opposed to an integrated amp that has those in one box. And a receiver is nothing more than an integrated amp with an AM/FM tuner built inside as well.

Breaking them up into seperate pieces of equipment gives you tons more flexibility in system configurations, but the price skyrockets as well :)

No just for the sub out, which is all you really need. And the amp inside of the Yamaha Recievers is a good amp so atleast for now you don't have to worry about an amp for the full range speakers....

I just bought the amp for the mag 12. All I need now is a sealed enclosure. Should I make it myself, or buy it? I have minimal experiance with making enclosures. Not to mention, a cheap sealed box will cost less than if I buy all the tools and build it myself.

Here is the sub.

I just tested the sub out free air for a minute using an audiobahn amp that puts out 400watts at 4 ohms. All I can say is, I can't wait to get that 1400rms amp!!!

400 audiobahn is probably about 300 real world. It needs some real power.

Oh yeah...I'm not extremely computer savvy...but I believe most soundcard outputs are 1/8" mini jacks. So then you'd just need a mini-jack to RCA wire, and then connect that to the inputs of the amplifier.

Something like this (http://cgi.ebay.com/3-5mm-1-8-Y-adapter-stereo-mini-plug-to-female-RCA-jack_W0QQitemZ5868002741QQcategoryZ32833QQssPageNa meZWDVWQQrdZ1QQcmdZViewItem), then connect the inputs on the amplifier to these outputs via regular ole RCA.

Will my amp work with that cable? I was looking at a picture of the inputs in the back and it didn't seem like it would work.

This is what the description said.

Balanced XLR and 1/4" TRS inputs

Let me know if that was the right converter to get or if I need something different.

"I'd be interested to see what the Behringer could do but it's definitely not made for HT. A few things to point out: 1. It has to be rack mounted for proper cooling. 2. these types of amps usually have pretty loud fans moving the air through them. 3. It doesn't have a low-level RCA input which is a huge downfall. Did you look at the connection types? It only takes XLR or quarter inch connections which no HT receiver or power amp comes with. It's meant to be connected via a sound board. I just don't think this will work. The BASH amps are excellent amps. You'll see them listed on some of the better powered subs out there (in the $400-$1000 range)."

That is what someone else told me on another forum who has had a lot of experiance with home theaters. Becasue of that I am probably going to buy two of these to power the mag.

http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=300-752

You think buying 2 of them and hooking them together to run 1 sub is ok for a HT?

JimJ
02-26-2006, 12:34 AM
That guy, frankly, has the complete wrong idea.

Yes, Behringer and other pro audio-derived rack amps need some special considerations in interfacing XLR to low level RCA found in most receiver outputs, but there are workarounds for it. And there are replacement fans that will solve the fan noise issues.

The fact is that Behringer and QSC amps are some of the most cost-effective solutions for powering relatively high power home sub setups :)

Well tomorrow I want to make my choice. I will either go with the behringer or 2 of the other amps I showed. Does anyone else here have an opinion? JimJ you seem to know what you are talking about. It is only about $100 more for the bash amps, so price really doesn't matter that much. Just let me know which you think would better power my sub.

I am on this forum, SSA, CarStereos.org and Automotiveforums.com

I might have, I don't remember, but I will have to hold off on that review till I get my crossover in and get the behringer hooked up permently.

My initial thoughts of the amp hooked up to my mains...

****, the fan is NOISY, but it moves alot of air.
Heavy as hell (40 pounds, but hey, if it pushes that much current, its got to be heavy)
Hella powerful, don't even have to take the gains off minimum basically for my mains if I have them hooked up to it.

*edit* The downside is I can't get full power out of it here in the dorm room cause I would blow the breaker... Sooo, its prob alot bigger than I need, but hey, you can never have enough power!! *Tim Allen Grunt*

I'd be interested to see what the Behringer could do but it's definitely not made for HT.

To me, an audio amp is an audio amp.

It has to be rack mounted for proper cooling.

Not true. Here is my four proamp stack running without any rack. Amps sitting
on top of each other. No big deal.

http://home.pacbell.net/lordpk/qsc/PLX3402-100.JPG

these types of amps usually have pretty loud fans moving the air through them.

Some proamps have variable speed fans. At loud volumes usually you don't
hear the fans, at low level listening the fans are spinning slow, less fan noise.
The reason pro amps have fans is because they pack a butt-load of power into
a small footprint, RU chassis size. If the same pro amp were designed to be
fan-less, the amplifier would be 3x bigger in size.

It doesn't have a low-level RCA input which is a huge downfall.
Huge downfall ? You can get a cheap RCA to XLR adapter cable.

It's meant to be connected via a sound board.

no

I just don't think this will work.

Pro amps have gain controls so if your RCA signal is weak, turn up amp
gain.

The BASH amps are excellent amps.

yes

Those are all nice amps. The first 2 I liked the best. I am probably just going to stuck with the behringer becasue it is about $150 cheaper than either of those and should still give me 1400rms at 4 ohms. I don't think i will need much more than that.

Is the Behringer built on the same chassis as the RMX1850HD? Just somewhat less material in it to make it cheaper? Just wondeirng cause the back panels look basically identical.

thylantyr
02-26-2006, 09:30 PM
EP2500 is a RMX2450 clone but it has a smaller VA rated transformer so it's
total output power will be less than a 2450. Nothing wrong with the
clone, but there is a reason why it's $300 cheaper {list price} vs. RMX, it less
power. Nothing wrong with less power, but it's nice to know what you have
vs. the marketing jive which may falsely mislead you into thinking you have more.

The 1850HD is the same as 2450 but with reduced rail voltage, a clever method
to call it 'HD' {heavy duty} without having to redesign a new amp - just use the
2450 design. QSC does this with the new PL and PLX amps too. PL236 is the flagship
design. Take that design and do small things to the PCB like remove some parts {etc}
and re-badge the amp as a lesser model. This reduces manufacturering costs
vs. redesigning a new amp every time.

There is alot of comedy is the audio world if you dig deep.

I will atleast try to hook up all the surround sound stuff now. The TV should be in this week also. But I really can't wait to hear the sub. We decided to tune it to 25hz so it would still be able to hit the lows that you want to hit in a HT but will still sound great playing music. That was all Tirefyres idea and it seems like the right way to go. Also, the speaker wire for my surround sound I don't think is going to be long enough. Not to mention speaker wire in Home theaters seems to be a much higher gauge them car audio. I am going to have to pick up some serious amounts of speaker wire. Especially with a mag sub that I don't want anywhere near my new TV!! Does anyone know the correct gauge wire to wire everything with? If it is the same rules that apply to car audio then I can figure it all out. Which i bet it is. I have 5 100rms speakers, being powered by the reciever, and the 1400rms sub. I am guessing I will deff need to atleast get a smaller gauge wire for the sub wiring.
