Well folks, My 901 phase has come to the end. I sold all my 901's. -It just wasnt worth it.. I was putting>1000 watts into them AND a additional Jbl sub with a Crown amp to get the sound I wanted. and even then, it was mediocre. I'll give them credit tho- the vocals and midrange were exceptional. When I used them strictly for mids- they were nice.- but not worth the hassle. No regrets- When I was a kid I thought they were the greatest, and someday I'd get them.- So I had to give it a shot and see for myself if I liked them.,,, and I really cant say I did.. -- Onto the next-- I'm putting together a Jb pro Cinema 2-way.. got the mid/lows, now I need to find some horns...

I've had more expensive,- but my favorite-Klipsch Forte's! They seem to make listening more enjoyable than any others. And I know it may sound crazy, but my Cerwin Vega D-9's have always been a great workhorse and always seem to surprise me whenever I listen closely.. To me owning a speaker is a lot like owning a vehicle.- I'd MUCH rather have F-350 truck, that can take you ANYWHERE,- than a Ferrari that only pays off within a limited range of music, and ONLY if all conditions are near perfect. IMHO

Ok- So I got all the drivers done, and I'm taking them for a quick spin.. 14' x 25' living room set-up single speaker forward, on the short wall Running them with my M-1.0t's in mono, Mp3 signal feed through my sunfire theatre Grand III - a dusty series iv bose equalizer , and If i need to equalize further I'll run the signal through my ADC eq additionally. I started listening to A Perfect Circle, and I have to say that I'm very surprised with the depth. When I was aligning the drivers with my signal generator, I didn't think I'd get ANY low end. but there's plenty- certainly no need for my Sub So far my first impressions are pretty good.. Although I'm dumping a TON of power into these things.. - Can I really crank the hell out of these?- because I'm already lighting up my amp meters without the decibels I've been expecting. It seems to me that the 450 watt max rating isn't going to relate to db's when there's so much power pushing those poor little 4.5" drivers to get the range I want. If it was just mid-range, I'm sure they would blow the windows out. - single driver forward is noticeably better sounding- deeper sounding, and when they face backwards, sound is very fatiguing .. I need to mess around with these things for a while more.. and not this late at night when the neighbors are probably trying to relax..

I just need to make sure which ever bose901 driver I buy is 1 ohm .. --Another question- Is the front driver the same as the rear 8 drivers??

Using rubbing alcohol works great.. I dont see the need for using such aggressive chemicals. in fact, I tried to take the brand-new surround off a blown speaker and it was impossible- the new surround was bonded so well to the cone. dampen the old glue and foam with rubbing alcohol and its softens it up into a paste that comes of very easily and completely. maybe other surround materials require stronger chemicals, -but for foam I cant imagine it going any easier.

Do you guys think my series iv drivers are the same as series v or vi ??? I cant find drivers for series iv,,, onlyfound them for v and vi..

Pindrop-[using a 1/4" or 1/2" sharp chisel]- First you remove all the deteriorated foam and carefully scrape all the glue off the basket then you wet the foam and glue around the cone with rubbing alcohol, and very carefully scrape the loosened glue off. There's step by step videos on yutube- look for 'speaker refoam'

Well, I have one speaker that's blown... All scratchy, no matter how hard I try to center the cone. Anyone here know where I can get ahold of a factory 901 speaker or two?? I imagine Ill run into another bad one...I know I could buy a replacement from parts express or Dayton, but I'd rather keep them all bose for resale purposes...

Thanks guys!- I'd love to post pictures, except they're all too big apparently..still trying to figure out how to decrease photo file size..

Oh,,,,Re reading that- I guess that did sound a touch defensive..my bad.. I was just stopping the lynching before it starts..901's aren't a 'typical' Bose product. If they dont impress me, I'll sell them, or use them for rear speakers in my theater room..
