i'd say the subs aren't a bad choice for the price. the h/u isn't bad i'm not a kenwood fan at all for the 200 or so price tag i'd looking into like the pioneer 4500 or 5500. for the amp, i'd go with a jbl 600.1 good solid amp. and if you want to take the chance of giving us guys on the forum a chance to help you out, i'd build your own box and 1) save yourself 30 bucks and 2) be happier with a sealed box for those subs than a bandpass.

^the above recommendations are the way i'd go^

the pioneer HU will offer better quality and performance. Also, a sealed box...made by you will sound much better with those subs. than any pre-fab bandpass will.

missing... yeah...

Well, only about 4/5 th's of the musical spectrum! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

More than 8 out of the 10 audible octaves...

Maybe make a small consideration for that? //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

Personally, I'd invest in a nice HU, nice set of front speakers, and an amp to power them, as my first investment.

Maybe a small sub could still be fit in the budget even, round the whole system out...

The Infinity Basslink is a great option... a 10" woofer and 10" passive radiator, in an enclosure, containing it's own 200 watt class D amp, you can grab one of those for $200, and they actually work very well. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Oh yikes...

Rethink that enclosure...

"universal" and "bandpass" are oxymorons.. seriously. Eek..

You NEED to design a bandpass enclosure around the very unique Qts and frequency response property signatures of each individual sub out there... subs are not even close to being "all the same".

Simple sealed, or ported enclosures are generally much more "universal".. although some would argue only sealed boxes really fit the "universal" role.

Even in deciding between sealed vs. ported though, you need to know what type of enclosure your subwoofer will be best suited to... some subs have high Qts properties which make them best suited to sealed, while others have low Qts properties which make them best suited to ported enclosures.

As far as bandpass enclosures go, that's only ONE (to determine 4th or 6th order BP) of a whole bunch of considerations as to what woofer will fit what bandpass type, and what chamber ratio's/volumes/tuning frequencies will be used.

And I don't want to do any more bubble-bursting...

But has that Visonik amp been tested?

I know it's understood that Visonik is a brand more akin to Boss than it is to Brax...

But look at that amp, and those power claims.

350x2? And with no impedance... that may be 350x2 at 2 ohms, which would be a 125x2 amp, not a 350x2 amp... and even that is if that's not an "optimistic" rating.

I think I'd locate a more reputable brand, you'll be glad in the long run, not only because the better amp will still be with you, without any annoying little "this" and "that"s, but also because you wont' be wanting to upgrade away from "that POS" down the road. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Have you checked Crutchfield? That deck is $249 there, AUTHORIZED, and you can get a free sirius tuner(sirius is good stuff). Crutchfield also gives you the wiring harness, and dash kit. Here is the link, just for your information:

I will only be listening to rap, other people tell me that bandpass is the best for rap. True or what?

I think bandpass boxes are pretty rare these days. They are supposed to get pretty loud, but just about everybody will say they sound like complete crap. I would just get a ported box and call it good(for rap). I prefer sealed boxes, but I don't listen to rap, either. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

[colt325e 10+ year member]

The bad thing is, i dont know what a 'good' system sounds like, i mean i can tell if something sounds like complete crap, but i wont be able to tell that much, cause this is my first system with my first subs.

Is this amp better? http://www.millionbuy.com/bosr635.html

 

[ngsm13 5,000+ posts]

not really. If ur looking for budget amps that will still perform well...look at jbl, profile, pioneer (premier), and u.s. acoustics. Look at the RMS power ratings, which is the actual amount of power it will continuously provide at te specified ohm load...not some bogus MAX # that it will never touch (like that boss amp) peace

The problem isn't whether a particular TYPE of enclosure is appropriate...

The problem is that unit you linked to is a universal bandpass enclosure... and that's simply an oxymoron.

You truly need to design a bandpass enclosure around the very unique Qts and frequency response property signatures of each individual sub out there... subs are not even close to being "all the same".

And inherently, a "universal" bandpass enclosure simply skips the "design" step - critically important.

I'm sure there's a few subs out there that would work fine in there... but how do you know? We don't know the chamber volumes, tuning frequency of the front chamber, etc.

Think of it like this.

1) Big balding guy in a football jersey holding a beer, eating pretzels, watching football on his sofa while his wife cleans in the kitchen.

2) Dark haired 30 year old executive wearing a Hugo Boss tan dress shirt and $200 slacks, doing his hair in his upper Manhattan apartment.

3) 19 year old college student party animal, life defined by seeking the easiest drunk girl, uses college loans like an income.

4) Pregnant and barefoot housewife talking on the telephone during daytime soap operas, gossiping with friends.

Do you think that you could build one house, one club, that would bring out the best in all of these people?

Subwoofers have many unique features themselves, design attributes that lend themselves to particular strengths and weaknesses... motor strength, frequency response, excursion, impedance characteristics, etc..

And while you really could build a bandpass enclosure that would flatter each one of these particular strengths/weaknesses... it requires designing it around the individual sub.

There's no "designing it", with a universal bandpass.

How do you know what combination of features that particular bandpass box was built to flatter? How do you know what weaknesses it was designed to minimize?

You'll be much more likely to find success in buying a "universal" sealed or ported enclosure. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Again, this is something best designed to a particular driver, but it's easy to find a sealed box that'll work fine with many subs, and almost as easy to find a ported enclosure that's conservatively tuned and large enough to be reasonably "universal".

But one thing that you need to determine first of all, is whether your sub is best suited in a sealed, or a ported enclosure.

If you are listening to rap all the time, I have no doubt you want a ported enclosure - and a sub that will work ideally in that type of enclosure.

Which also means you really inherently won't want a 4th order bandpass enclosure, like that is (and like 100% of the "universal" bandpass enclosures on the market) - because they are more ideal for woofers that are best suited for sealed enclosures. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Trust me, use the KISS rule.

...and what about the majority of the frequency range? Why only a sub?

Bass is fun, but you'll end up with the same poor-sounding system you have now... just disproportionately bass-heavy. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

If you cant already tell, i am a newb to this stuff, and i need to know what a ported box looks like compared to a sealed. As far as i can see on incredibly cheap millionbuy.com, it doesnt say what it is.

-colt-

 

[geolemon 10+ year member]

pretty simple...

A sealed box is as it sounds... sealed.

It's just a rectangle with a sub mounted in it. The air inside can't escape.

It exists solely to contain that rear-wave energy off the backside of the sub, that is 180 degrees out of phase, and would cancel with, the energy off the front of the sub... to make sure that the sub can perform.

Certain subs are ideal in sealed enclosures, many specs of a sub contribute to determining this.

A ported box deals with the same issue, but rather than constraining that otherwise-sound-cancelling energy off the back of the cone, it has a length of plastic pipe mounted in it, forcing the escaping energy to travel through a known air-resistive additional distance, effectively delaying the escape of that sound energy, putting it more in-phase with the sound energy coming off the front of the sub, creating in some cases up to 3dB more output than a simple sealed enclosure, the greatest gains occurring near "the tuning frequency" of the enclosure... but losing air spring inside the enclosure as the frequencies drop below the tuning frequency.

Certain subs are ideal in sealed enclosures, many specs of a sub contribute to determining this.

Bandpass boxes slap on an additional chamber over the front of the sub, forcing all the sound to travel through that "front chamber"s port, which has some benefit if you know what they are (ie. additional boost, acoustical filtering, etc).

Important to note that the "rear chamber" of bandpass boxes can be either sealed (4th order bandpass, single-vented) or ported (6th order bandpass, or dual-vented), and that subs may be best suited for one or the other.

Check out JL Audio's tutorial on enclosure types for more info.

Ive been dealing with those lower lines Visonik amps for a while now and I'd just like to say that they are a good bang for the buck (cheap power). Id rate them along with Power Acoustik and Profile. They do have an annoying whine due to an internal cooling fan but other than that they perform well.
