Re: bose 901 v1 adding a amplifier

You may connect an additional amplifier to the Rec Out or Line Out from your existing receiver.
Please note the Bose 901 equalizer can be used to connect to one amplifier only.

Do let me know if you have any further questions.

I'm trying to hook up a Carver HR-752 to Bose 901's series VI, I would like to use the preamp out and in on the back, do I need a seperate amp to use these? I have them going through the Tape

To setup the Bose 901's so that all of your connected equipment's sound (cable/dvd/games/stereo/etc) comes out of the 901's.
If you already have a receiver with front left and right pre-outs, I would add an amplifier. (other option is a pre-amp) Use the amplifier to create the loop the 901's need w/ their EQ and it will also add a cleaner sound and added power. That's how you can really make the Bose 901's sound amazing.

Adding Subs to a Bose 901 system

The Bose system has sound that is unmatched, the 901 with the equalizer is amazing. I have done what you are thinking of doing, the speaker runs 5ohms giving more power to the coils, adding a sub will color the sound and will not give the desired results, the 901 equalizer may be damaged with the modification of the sub, not recommended.

I cannot connect my bose 901 series v1 active equalizer to my denon av surround receiver avr-891

Short answer from personal experience.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

The reason: You can't use the Active EQ (or ANY processor) in a tape Monitor loop with anything but 2-channel stereo material. As soon as you activate the loop you lose digital sources.

Adding to YOUR particular problem is that the Denon doesn't have a volume-controlled pre-out to feed that amp. If you want to deal with controlling the separate amp volume manually you COULD connect the Active EQ between DVR Out and the 901 amp IN but you would have a stereo mixdown instead of true front channel from the speakers.

I want to hook my bose 901 VI along with EQ to my Luxman R117 Receiver and also run other speakers from the same receiver. Is this possible?

If you are using the Bose Equalizer to optimize the sound of the 901s by going through either a tape loop or a pre-out/main-in loop, then the only way to do this without also equalizing the sound sent to the second set of speakers is to manufacture a "zone-2" output from the Luxman.
You'd probably need to split the send from the Luxman's pre-out before the EQ and send it to a second power amplifier for the second pair of speakers (if you want the Luxman's volume knob to control both speaker sets) or from a tape level output (if you wanted independent volume controls for the two speaker sets.
The whole EQ thing made 901s difficult to use on vintage equipment with only one "zone" audio outputs. Unless you want to use the Bose EQ on the second set, too, you can't do it satisfactorily without adding another stereo amplifier. But, go ahead and try it, you might find that you actually like the odd EQ that the 901s EQ gives to the second pair!
If it were my decision, I probably would not do it without a second amp, but it's all about what you like, my opinions really don't matter in your house, do they?
Have fun

I have a pair of bose 901, v1 I have a old pioneer vsx 5300

Not knowing anything about your specific amplifier or if it correctly configured for the 901 Active Eq, the first thing I would say is these are designed for analog stereo sources ONLY and a multichannel digital-capable receiver will NOT work properly with any devcie in a Tape loop.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

Connect the Active EQ between the pre-outs and the amp input. Run speaker assignment, levels, etc and have fun.

What would be the best amplifier for a pair of bose 901 series v1 speakers. they are 450 watts max. i need good clean power and lots of it. what do you recommend.

I'm partial to any old Carver amp. Some M-400 Cubes bridged to 400 WPC would blow the walls out for you. Or if you want to keep some semblance of peace and hearing ability, I'd just get a nice M-200 for them. I've had both set-ups and the M-200T is fine without being dangerous.

Can I hookup a Bose 901 EQ to my receiver and amp?

Your instincts are correct. In fact, the only way the 901's can live in an A/V system is with dedicated amplification.

Put that old amp back to work.

This is exactly how mine are connected.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

What kind of amplifier and other accessories are recommended for bose 901 speakers

I would recommend a high power 2-channel amplifier, minimum 16 guage speaker wire, and of course the Bose 901 active EQ that matches the series of your speakers. I use a Yamaha mx-830 power amp & cx-830 pre amp 170 wpc They (Bose) claim that they're unlimited power handling, But if you use a amplifier with to little power and overdrive it to make it louder, you could damage the speakers or amp. With my 170 watt class A amp,the 901 series 6 will blow wind across the room. Go with the best amp you can afford! best for money- Yamaha,Denon,Onkyo!

How to connect bose 901 speakers to 5.1 setup?

The solution is simple and cheaper than you think.

The analog 5.1, 6.1, 7.1 outputs on your receiver should be active even with digital inputs that you want to hear. Your receiver turns everything it processes into analog output just before the speakers anyway so there's no loss of access to multichannel sound this way.

What I did was to buy a separate amp for the 901's and feed the Front L&R analog audio out to the EQ which is directly in front of the amp. The Active EQ is only for the 901's which don't have woofers or tweeters so Bose flattened out its final response electronically with some serious boosting at both ends. Having it in line with any other speakers would feed them a grossly over-compensated signal.

Your receiver will drive the rest of the speakers.

This is the cheapest way to have your 901's and hear them, too. Since the 901's are really efficient you don't have to buy a big amp that would heat the room. I'm using a separate Carver amp with 2x100w for mine.
