Anyone Using Bose 901 speakers In A Home Theater?

Ive owned many speakers and none have sounded as good over a wide listening are as the KLF's. I know Klipsch takes some hits by hi end purists at times, I have been silly enough to buy into that talk in the past. Stock the KLF 30 lack extension in the top end, and can be harsh. The TI tweeter diaphrams made me a horn believer.

After many years in high end audio, there is one test that tells a speakers worth. After 2 yrs with them would I buy them again for the money.

Only a few have passed that and the KLF 30/Crites are on that very short list of 3.

I know that my response will be difficult to swallow since I am answering your original question and not either waxing rhapsodic about the sound of Bose speakers or providing a vehement statement that Bose is responsible for all social ills. Amazing. Anyway, yes, I bought a pair of Bose 901 Series IV speakers in 1981 and loved them for many years. I still use them in a quasi-home theater setup with my big screen TV providing the front speakers and the 901's for the rears, along with an old M&K subwoofer. I drive the 901's with an Onkyo receiver. I am not the world's biggest home theater fan but the sound of movies is pretty good.

I'm 64 years old. I don't know too much about high end equipment. all I can say is I bought my 4 901 series in 1971 during the 4 chanell era. till today I still have them so I don't know what I'm missing because I never heard any other high end speakers. I'm retired so I don't have funds to upgrade. one thing I do know is after reading and hearing since 1971 is that it's better too have too much power then to have enough power. so currently I have a McIntosh mc602 power amp with 600 watts per chanell.

Well g nakamato it sounds like time to experiment.  40 plus years is a long time to spend with any speaker.  Even state of the art speakers are going to have deterioration issues, let alone mass market items.
  Are you still in a 4 channel set up?  Is your amp driving all 4 channels?  Is your TV in the system and if so, do you have a center channel to help with dialogue?
   Your ideas about power are somewhat antiquated.  The amount of power required is most dependent upon the efficiency of the speakers.
  McIntosh gear has a high resale value.  You may be able to sell that behemoth and be able to fund a decent 5.1 surround system, including an AVR, particularly 
if you buy on the used market.  Audiophiles constantly Buy and resell gear and you will be able to get relatively new equipment at knockdown prices.

Just searched that power amp.  Someone is listing one for over $5000.00
Again, selling that off would fund  a really great sounding 5.1 system, even without buying used equipment, and it would probably sound several times better than your current set up
