Hows this receiver?

It has preouts for a sub amp so then I could get a sub amplified

It's good...just two channel though. I thought you were looking at a full 5.1 or 7.1 surround system? Or did you decide that wouldn't work out...

And don't expect to get a full 120W out of that before clipping. HT receivers are notorious for overrating output power. It's not like you need anywhere near that in home, anyway. 50W of real, unclipped power is really the most you'll ever need.

I have the HK 3470 and love(d) it. The problem is their was a power surge or something at college and it messed somethng up with it... its still usable but it now has lots of quirks :cool:

That's what surge protectors are for, nitwit :)

Lol

Well theres no way I will be able to fit a 5.1 or 7.1 in my dorm room...
Especially with how my roommate is


Of course Ill upgrade after college, but do you think this will work good for 2 speakers and a sub?

Well see the problem was my surge protector (yes I had one) was sitting on the floor and the reciever was at the top of my hutch right under my lofted bed in the dorm. The cord wouldn't reach all the way to the surge protector but it would reach to the wall outlet which was right there... I mean, what are the chances! :crying:

works great for me, and my dayton cabinets + e8a + PE plate amp.

Thanks

Would I notice the difference of that one compared to the one that puts out 80w at 8 ohms and 100w at 4 ohms?

Its like $30 cheaper.

That's exactly it. Murphy's Law...the lightning or power spike will only strike your equipment when it's not protected.

I was running two JBL 3way studio monitors, a NAD integrated amp with about 40wpc, and a 250W plate amp pushing a Shiva in 1.5cubes sealed...I was the loudest thing on the hall when I was in the dorms :) Trust me, a good two channel setup is all you're going to need.

Thanks

Now for plate amps..
The PE ones are good enough?

JimJ
07-20-2005, 03:18 PM
Yes.

If you're using under 500-600W or so, the plate amps are a very good value.

I've never had a problem with mine, but I'm only running it @ 8ohm, doesnt barely even get hot, but does push the 8a hard.

Yea I think Im gonna go with a DD 8"
Give it 240 from a PE plate amp

Where do people usually put plate amps?
They are integrated into the box usually right?

Yep, just cut a square hole in the side of the box and screw it in, the output wires are already on the back of it.

eww I need to dust...

Ah sounds simple enough.

It doesnt matter that part of it is sticking in the box?

Also what do people usually tune these boxes to?

JimJ

If you want to really get technical with it, you could calculate the amount of space you're losing and make up for it with the box design. Or, you could just stuff some polyfill in there and achieve the same thing:

Usually, HT/home boxes are tuned pretty low, anywhere from 20-25Hz.

Mine is tuned to high 20s. Low enough to get a good rumble from movies but with the space I was working with, any lower and I wouldnt have modeled up a very flat response.

btnhfan
07-20-2005, 03:40 PM
Thanks

Why so low?

JimJ
07-20-2005, 03:44 PM
Because you don't have in-cabin gain like in a vehicle...so you need to tune lower to compensate for the extra loss you're going to get in the bottom octave.

Also, a lot of action movies have subsonic material, from 20Hz sometimes down to 15Hz - you can't hear it, but it's what shakes your spine and rattles the walls.

btnhfan
07-20-2005, 03:47 PM
Ahh

What would you reccomend if its going to be for video games, lots of music (mainly rap), and some movies?

JimJ
07-20-2005, 03:52 PM
Anything from 25-30Hz should work fine.

Hey Jack will those speakers be able to handle that power, even if it is like 80w?

PV Audio

yes

That's what I thought you said...

in that case...

I'll have a good amp :)

btnhfan
07-25-2005, 12:24 AM
Jack those speakers arent in stock :(

Have any other suggestions?

JimJ
07-25-2005, 12:32 AM
I'm not surprised they sold out quickly.

Did you check out those Tang Band speakers I posted in a more recent thread? Those are the same concept...full range, no crossover.

btnhfan
07-25-2005, 01:02 AM
I will now

btnhfan
07-25-2005, 01:09 AM
Are you talking about those 3" ones?

JimJ
07-25-2005, 01:13 AM
Yes.

btnhfan
07-25-2005, 01:15 AM
They dont handle that much power :crap:

btnhfan
07-26-2005, 02:35 PM
Bump for JF

Those speakers look like they wont be able to take the power...

What else do you have in mind?

JimJ
07-26-2005, 02:45 PM
Go with a simple two-way system...maybe a 6.5" mid and a tweet.

btnhfan
07-26-2005, 02:56 PM
Do I have to design a crossover?

JimJ
07-26-2005, 03:02 PM
You'll have to figure out the component values and design to use, yes.

Tom (Acidburn) has a good thread about something similar over on SSA. Some info you might want to check out.

I think Ill just buy speakers that are already in their cabinents and stuff

Theres some vifa and daytons at PE

those daytons r the ones that i have in my current bookshelves. they sound extremely transparent, much unlike the PE ones (yes i've heard them because after i built mine i told my neighbor to buy the prebuilts with the same driver....they blow)
