dorm setup question

[mapolley07 10+ year member]

looking to do a 2.1 setup in my room, and I'm starting to plan stuff out right now.

I'm looking to build this PE project, which are about 150 rms each or so at 8 ohms

and I'd also like to add a sub in a coffee-table box, maybe a dayton 10 or so, maybe give it 100-200 rms, box will be ported

My question is what should I look for in a receiver/amp setup. I'm having trouble finding 2.1 receivers, or even a 2 channel receiver with a subwoofer pre-out.

Can I buy a receiver and plug that into a 2.1 amp or something along those lines? Never messed with home audio before, but car audio seems much more straight-forward than this is

sorry if i'm not clear with this, just don't really know what I'm looking for

I'm no expert, but a good 5.1 channel receiver should provide 400 - 600 watts for your system when it's run in stereo. That's what I use, but I have a 5.1 setup in my dorm.

how well do 5.1 receivers work with only the front speakers attatched? This system will be mostly for music, and in a small *** dorm room i wouldn't get the full 5.1 effect, so 2.1 is what I'd really like

Nope...

Nope...

Why no? Mine is rated at 600 at 4 ohms. So about half that when you consider I'm running it at 8.

And to OP, yes you can run 2.1 off a 5.1 receiver. There are settings that allow you to do so.

Your receiver is not rated to push 600watts @ 4ohm per channel in 2ch mode...

if your receiver was pushing 600W @ 4ohms then you have the most powerful home receiver...ever.

Denon's flagship (POA-A1HDC) amp pushes 500W @ 4ohms BRIDGED but yet again it's fn' $7000. (150Wx10 @8 and 300Wx10 @ 4 otherwise)

To the OP

Those Dayton's are rated at 50WRMS (both) so I'd shoot for around there.

This Onkyo might be a nice place to start: http://www.crutchfield.com/App/Product/Item/Main.aspx?o=m&showAll=Y&g=10420&i=580TXS506S&tp=179

Ok, good to know. Like I said I don't know much about home audio. So it's a max rating, then?

 

[negativezeroz 5,000+ posts]

Most likely it's incorporating all channels driven at once such as 120Wx5 = 600W. Companies tend to do that...

So stereo would just be 120x2. In home audio you do not need a crap ton of power to accomplish something great. Besides, take that Denon amp I posted, if you ran that on a 10ch setup at 8ohms, to get 3dB louder you'd have to have speakers cable of 4ohm loads or get another one and bridge every channel so you'd have 500Wx5 on each amp (going that route you'd be gaining over 3dB more like 5dB at that point but bleh)

so does anyone know of a good receiver that would fit my needs? like 150rms x 2 channels @ 8ohms? this figure can be in bridged mode also. I need a pre-out for a sub too

would like to keep it under $200 if possible

my bedroom setup is a dayton120 from parts express...loud as hell...then some small speakers made by PVaudio on this site...they have a 3 " aura and a small tweet...off a tiny 25x2 amp i think...sounds great...downstairs is oldschool with 4 old big floor speakers and a 100x6 receiver i got off ebay for $20

Also check goodwill. Every once in a while people throw out some great older receivers and you can buy them for like $20.

Did you not read my post? The woofer and tweeter both handle 50WRMS. Why would you give them 3x their rated power?
