Any opinions on good cheap av receivers?

[lovinthehd]

mayhapse

but on that note i figured id need a stereo amp per pair of speakers and a mono amp powerful enough to drive all 5 subs so id be looking at a minimum of 4 amps i dont know how much that is in $$$ but its definitely more than the 400$ I dropped on this decent avr.




im not actually planning on playing a concert for the neighbors and if i was i wouldnt be in the room while doing it

Likely you only need power amps for the mains, I wouldn't bother with surrounds, just let the avr do those. You have what 5 passive subs?

5 subs?! You have 5 passive subwoofers in your system? You need more than a mono amp to drive all those! How do you figure you'd need 4 amps?? Where are you getting this information from?

You could buy a single 2 or 3 channel amp for your front speakers and be done.

i thought crown amps and rack style systems were in stereo and mono only.
(1 for my mains 1 for the surrounds and 1 for the center and the last amp for the subs)

well they aren't ALL passive but the 2 10" in my mains are pretty much passive if i bypass the "bi-amp crossover" and the other passive sub is my jbl HOWEVER the plate amps on the polk 10" and the logitek 8" are not the best in quality so getting a single high power amp for all 5 and a dsp to even out the kinks was the way i was aiming for.

The Sony 1080 if you already have that doesn't have pre-outs for an external amp (except for the sub and zones) so no power amp option. The Crown XLS amps are 2 channel amps but are bridgeable. Crown does have some multich amps but they're going to be significantly more expensive than the XLS amps IIRC....

You're probably best off just using the plate amps the subs came with rather than buying amps for them (plus they may need particular dsp that their amps provide). The 10" woofers probably are not "subs". What JBL do you have?

"JBL SUB135P Powered by an Acoustic Audio WS1005" and no the 10" in my mains are not subs they are just regso woofers but i figure i can tweak them with a dsp.

I think you're confusing the woofers in your speakers with subwoofers. A subwoofer is a stand alone speaker designed to play bass frequencies only. The 10" drivers in your main speakers are not subwoofers. They are part of the whole speaker, and bi amping is not something I would even consider as a part of my budget requirement.

You do not have "5 subs", lol.

Buy a better sub. You can't just get a different amp for an active sub. A better amp in a crappy design won't improve anything.

I think you need to understand the basics first, before you go jumping into dsp. That costs money as well, and I definitely recommend using it to achieve better results before I would recommend more amplification, but I think you should have a good understanding how all of this works before doing something so advanced.

well the design seems fine i dont get any audible chuffing and they are pre filled with polyfill also with supports and beams all made with 1/2" mdf, the box and ports fit the sub calculations and are a good build quality.

I only said that because if you think you need a better amp for it then it must be lacking somewhere for you to come to that conclusion. If it's working fine and a good design then what's the issue? Why even think of replacing the amp?

Wow that "sub" amp only has a frequency range of 50-200hz? I agree with Pogre, time to start with one good sub. 8" barely qualifies in the first place....

your right i will need to do some research but i figured if im gonna do a rack system diving in is the only way to learn. im a learn the hard way kinda person.

You've mentioned that a few times....what do you mean by rack system?

funnily enough that sub seems to hit the lowest of my 3 dedicated subs at least from what i was able to tell by ear.

Well, you can have nice components and a competent system without having to go with a "rack". A simple tv stand with a shelf or 2 should work just fine.

 

[sizzam]

like several crown amps chained together and a dsp or 2.

That doesn't mean much. A true sub should do 20 hz at reasonable spl....the Polk may do mid-30s, the Logitech maybe in the 40s....the JBL is rated 6dB down at 35hz....and doubtful your woofers in the speakers are even as good as the Polk.

well the plate amps are only 50w max and the driver seems to have more room for power without blowing or frying so i was gonna get a higher powered amp to run the driver.

Chained together like with a bike lock? You can actually stack the Crown XLS amps on top of each other, tho since they don't require ventilation above or below the amp due to their fans. I do ziptie two together on the bottom shelf in one system, keeps them lined up What dsp options are you considering?

I wouldn't count on that scenario
