Just getting started on a budget and need bookshelf speakers/receiver now
Get the Elac UB-5's! Superb 3-way speaker designed by famed Brit Steve Jones (TAD). There is a pair now available on EBay for $408.91 (free shipping) from seller "savarety-official-store". That is about $100 less than the other sellers!

Another good budget choice is the PS Audio 4. I have two! Quite affordable! 
inherent design flaws with a 3 way, 15" / 8" / horn (large tower) speaker?
A 15 inch woofer can go up to 800hz easily in a two-way system. Altec A7's (VOTT). Same for the Altec 19. Why waste money on car speakers? Vintage Altec 15's can easily be found on EBay and other sites. 
Add speakers lose power ?
Stick to 2-channel (the Polks) or go home theater if you want extra speakers! 
Add speakers lose power ?
You are not losing power! But your sound quality will surely suffer from adding extra speakers! Otherwise get a 5-channel HT receiver and do a full home theater setup! And seriously, those Bose cubes are really cr*ppy sounding!

Hafler DH110. Excellent SQ! Available often for less than $200.

Your Polks definitely need jumpers to work properly with just one set of speaker cables!

Sure, you can connect the Polks and the Bose cubes in parallel. But the total sound will be cr*p!

What a stupid idea to put those cr*p Bose cubes on the sides! Stick to the Polks alone and throw away those Bose cubes!

Do you have the required jumpers on the two pairs of terminals on the backs of the Polks? Red to red, black to black?

The proper size cabinet for a 15 inch woofer is LARGE! I had a pair of vintage JBL C36's with the 2215 woofers. These had the "James B. Lansing Signature" logo on the top front edge. 
JBL L5 - Frozen Voice Coil (Woofer)
Too much power at bass frequencies damaged the voice coil. Overheating! 
Can I really sell this cartridge?
NO! 
Rectifier Tube Rolling in a Modwight LS 36.5DM
I have found more data: same pin-outs and construction, equivalent electrical characteristics. So the Russians just copied the 6CG7 (including its internal shield). Shame on ARC and others for calling it a "super" tube - and boosting the prices! A... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
Also plenty of choices for the 6N30 - from low-to-high prices (Saratov-made DR versions). Shame on ARC and others calling it a "super" tube - and boosting the prices for the gullible!
