Help w/surround audio setup

My klipsch 4.1 Pro Media Speakers subwoofer is blown. I stopped using it with my comp & started using it with a DVD player & the sound to me was nice (unplugged the 6.5 subs). I figured why not just get a receiver & sub & use this setup to connect to my TV for movies, to listen to music, & watch TV? Ive never done this before so Im asking for advice on what you guys think? Here is the receivers Im looking into: http://www.amazon.com/Yamaha-RX-V37...qid=1390345776&sr=1-1&keywords=Yamaha+RX-V375

The sub is being sold from a friend not sure on the price but Im thinking maybe 50 if its still in perfect working order: http://www.crutchfield.com/S-aLR5GroCRaL/p_065PV500/Boston-Acoustics-PV500.html He also has the 700 version

Will the speakers work with a receiver? The speakers themselves are powered so I don't think they will work with a receiver. The ones without the volume control would work, but I don't think the Klipsch speaker with the volume and sound controls would work.

So then I would only be able to use 3 speakers? Im not sure how true that is I believe the klip rep told me all 4 can be used somehow...What Im wondering is will the SQ be a lot better using a receiver over fixing the klip sub & using that?

I can't say for sure since I couldn't find a picture of the back of those speakers. Are the 4 speakers connected to the sub with regular speaker wire? If so then connecting them to a receiver wouldn't be much difference. But most of the time when you see a speaker with volume or some other controls that means it has some kind of electronics inside.

I sent you a PM with a link to another forum where someone was wanting to do the same as you and apparently it is do-able.

As far as your links I think if either receiver fits your needs and budget they will be fine. I had a Yamaha receiver and liked it. I only recently got a Denon just because of the HDMI inputs.

Yes there are 4 speakers wires ground/pos for each satellite. There is also a preamp plug that comes from the main unit with the control knobs. Obviously this would not be getting power so the main knobs on the unit would not function the satellite would just be powered by the external receiver. But Im wondering if anyone has done this & how the outcome was as far as SQ vs using the Klips amp in the box?
The Yamaha I posted above also has HDMI but Im not sure what the diff is between the two...This will be my first receiver so Im looking for opinions.
Thanks!

No problem using the promedia satellites plugged directly into an AVR. Just ditch the broken subwoofer etc and buy something new.

Alternately, you could buy a BASH 300 watt amp from Parts Express to power the sub. You will still need the AVR for the satellites, and the price of the PE amp is approaching that of a new sub.

Bear in mind the RMS power of the amplifier vs the RMS power of the speakers.
I use a larger amp than the speakers so I dont risk clipping the amplifier to get the most from the speakers, but I am careful that the bass cones dont exceed maximum excursion.
(currently running 300W RMS/channel into 200W RMS speakers)
If the amplifier is a lot more powerful, you risk blowing the speakers when there is a loud noise, even if the volume isnt high.

Your speakers are rated at 60W RMS per channel.
Judging by their size, this might be a bit optimistic, to be safe call it 50W.
In this case I wouldnt put an amp on them of more than 75W/channel RMS.
You need to observe what is too loud for them before you cause damage and be careful how loud the media is that you are playing as this can vary a lot. Its easy to make a mistake. Even a mains thump can cause harm if you oversize the amp too much.

The SQ is dependent on the quality of the AV amp you buy.
Cheap AV amps arent usually that good.
Second hand higher price AV amps going cheap can be a good buy.

SQ is also dependent on what is doing the analogue to digital conversion.
Cheap AV amps arent that good, midrange to expensive AV amps are ok (generally, there are many exceptions so read lots of reviews)
A good soundcards analogue out will compete well and can be a good way to improve a cheap AV amp, but you need to have multichannel analogue inputs on the AV amp to make use of this method.


note:
some AV amps let you limit the max power output.
For these you can get as powerful an amp as you like and set the limit to match the speakers.
