What to do?

So here is my delima. I have a Onkyo TX- SR600 with Wharfdale W60D's on the B channel and Bose 901 Series IV on the A channel. I want to increase my wattage to the 901's with out destroying the Wharf's. My idea is to run the A channel out to a 2 channel converter, then to a small 50-100w amp then to the 901 EQ(when i get it) then to the speakers. Any ideas would be appreciated.

I don't understand the mixed pairs thang either. I stack two pairs of the same model because they're bookshelf speakers and one pair alone sounds a little thin.
 
Room Size 30' X 18'. I am just trying to have a rounded sound with the full sound of the Bose reflected off the wall and pinpoint sound of conventional speakers. I am new to this and experimenting but thought it would be a good idea.
 
If you're going to experiment that way, make sure the direct sound is reaching your ears a lot earlier than the reflected sound.
 
Do what I did when I ran my Energy Pro-22 Monitors with a pair of Realistic Minimus 7's off my 100 wpc Stereo Power Amp. I bought a cheap Radio Shack L-Pad and connected up the rear Minimus 7 speakers I used for Video to it and turned the volume down to the level I wanted. Worked perfectly.
 
Yeah I am only in $100 in this set up. What would be a good receiver to upgrade to and not break the bank?
 
The Bose EQ is supposed to be installed in a tape monitor loop or between the pre out/main in, feeding it from the speaker terminals will destroy it.
Your best and least expensive option would be a stereo L pad installed on the set of speakers you wish to attenuate.
 
Thank you wmgwizard. I was unsure what to do. I am contemplating dumping the Onkyo but am not sure what would be a great alternative for a decent price. It would have to be able to accommodate my TV which only has a digital out.
 
Harman Kardon PA4000

The PA4000 would be right for you. They are not very common, I had a hell of a time trying to find one when I bought it new a few years ago, now I imagine they are still harder to find used at a good price. It is actually 4 pair (8 individual) of 50 wpc amplifiers. You can bridge them and you have 4 "outputs" 100 watts each you can use to power each speaker. That is how I use it, I have 2 amps for a total of 100 watts to power each of my 4 speakers (I also like the sound of 2 front and 2 rear speakers) You can use it a number of other ways, even different signals to different speakers, but I use it to power only one signal. In the rear it has a whole bunch of bottoms and plugs and stuff, but the only ones I use I think would help you solve your problem. There are 8 bottoms you use so you can individually raise or lower the volume of each speaker to your desired taste. I set mine with the front speakers just slightly louder than the rear ones.

Sorry, I forgot to mention this is an amp. You will need to use your Onkyo as a pre and route the signal to the amp.
 
Better to have your input sources hooked up to a preamp that has two outputs. Each output would then have an amp that drives the specific pair of speakers. You could then wire in the Bose equalizer between the preamp output and the amp that drive the 901's.

If the amps have input attenuators, you can then adjust via the preamp for overall volume, and the amps (and the 901 EQ) can give you relative adjustments for each set of speakers, which allows you to blend and mix to your heart's content.

I wouldn't run the two pairs off of one amp, there's just too much potential for interaction and possibly making the load harder for the amp.
 
A 30x18 room is largish but you'd probably be best served by getting a used power amp in the 200+ watts per channel class and using one set of speakers only. I would choose the 901's. A used amp can be sourced for $300 and I would not be afraid of a used pro amp like a Behringer or Crown if cost is an issue. Make sure your speaker wire is at least 12 gauge.

Because of modes in the room, the speakers should be on stands and you'll have to keep the speakers well away from corners and walls and have some way to tame reflections as has been mentioned. Is the room full of furnishings?
