The eq that runs the 901’s is a proprietary eq that nothing like a regular eq. A standard eq is increasing an incremental frequency. The 901 eq is adding gain across a wide spectrum. When they say it could damage other speakers they are talking about crossovers that can’t handle the gain or current it puts out. I still have my 901’s. They hang in my garage. They are good party speakers if you like loud with no soundstage or imaging. I hooked them up one day in my reference system and then hooked up my 301 (used for front surround) and the 301’s sounded so much better. Friend had 601’s in high school and always liked their sound for what we did. Smoked a ton of weed and hash, dropped some acid and cranked hard rock and metal. Great memories but not serious reference quality.
Hello and "THANKS IN ADVANCE"
Recently I purchased a pair of Bose 901's and 601's. I'm running the 901's with the Bose equalizer through speaker "A" connections. The 601's are through "B" connections. I'm scared of the warning in the 901 owners manual that says the 901 equalizer may damage other speakers. Does anyone know where to set my unused 7 band graphic equalizer as to better duplicate the bose equalizer? it"s range is +- 12 db starting at 63Hz to 12.5kHz.

....parametric eq’s are better at the slopes, the ’gain across a wide frequency’ as @sgreg1 notes....they ’look’ like such, at least to me... (...shout out to retrovoltage.com for the graphs...👍) |
Perp, I sold all these products back in their heyday. To distill the various advice to clear instructions... 1. Your amp must have a "tape loop", "external processor loop", or pre-out/main-in jumpers in order to incorporate an EQ in the signal path. 2. The amp that drives the 901s should not drive any other pair...speaker B can only be another pair of the same generation 901s! 3. If your amp has only one set of tape or preamp outputs, use a pair of Y connectors to double (1M>2F), or use duplicate outputs if it has them, to run into a second amplifier...preferably an integrated, to set relative volume. Choose any line level input. EQ with your graphic if desired and if amp 2 has a loop too. 4. Early generation 901s (SeriesI and II) had MUCH more severe EQ characteristics than all later models, so the danger of damage to another speaker is greater with those. No graphic EQ is equipped with the boost to flatten the early ones' response...at 30Hz, they had over 20dB boost! |
