What the 901's did good, they did really good. What the 901's did bad, they did really bad.

A great speaker built with quality components. They just never sold really well, but then again, this was the beginning of the audio armageddon. Well worth it if you can find a pair.

Only mids and high frequencies can be bounced off of hard surfaces. Any way you wanna do it is up to you.

The 2000 watts is a pipe dream. Crown dosen't even bother to qualify it's rating. Do see max amp draw is 15A so good luck with 2000 watts plus output.

The Pro 4/aa is an iconic product. They sold a ton of them and they sounded great. But my head did feel like they were in a vise after an hour or so.

Nothing wrong with any of them, go listen and buy what you like best.

What was the mid changed with?

Boy, what a shame, great speakers. Might be worth it to find a decent replacement if a search for oem turns up nothing.

They are great, well built speakers, definitely worth the wait for something to come up.

I subscribed to Stereo Review from 1978 until their demise. Tossed them in the 90's. Regret. I've never found a source for viewing Stereo Review reviews but this is as close I have gotten. Missing are the graphs but the picture and complete write up is generally there. Scroll to the bottom...

3 and 4 are interchangeable and 5 and 6. Apparently the 6mk2 had a different eq curve.

Mid life series V till the end had treated foam which did not rot. Final version had rubber I believe, the 6mk2. Hanging from the ceiling they were some of the best speakers I owned. On the tulip stands had them sold shortly thereafter. If you can get a good deal on them, get them. Resale...

I don't think any of these companies thought their products would be expected to be in service 40-50 years later. With this in mind, I'm wiling to overlook a lot. I'm just happy my stuff is still giving me daily happiness. All of them way older than my college daughter.

Yet somehow Bose has a patent on the "acoustic waveguide" which is a transmission line.

As far as I know, the Stromberg may have been the original transmission line. 1936?

Is that a transmission line loading?

The Matrix line were one of my favorite B&W products. You really should do some research on their construction. Probably one of the most inert consumer production speakers ever made. The lattice bracing really is something special.

Bose 901 VI hanging in my garage were spectacular. Moved. Brought them into the house onto pedestals. Not good. Off they went. Sometimes regret it.

The 601's have really gotten a second life the last couple of years. Some versions are going for crazy prices on ebay. My belief is they have become collectors items in Asia. You asked about synergy between your Sansui and Bose. 8.5/10.

Looks like you've got the power for them. A great speaker. Still remember seeing them for the first time in a Popular Mechanics, must have been around 1978?

What is the story behind the gaskets? I've never seen anything like them on the 901's. Considering the old CTS drivers were probably the bulk of the build cost for the 91 it was no wonder they got into their own driver as fast as they could. I believe the early 901HVC drivers had the Pentagon...

This ain't nothing, you should see what a 901 box does with its sliders at maximum. I believe over 30 db of gain at the upper end.

Maybe it's my tablet but I can't click to enlarge your picture and with my eyes, I can't see it. And I'm always down for some good AMT goodness pictures.

Waveguide was what they called transmission line loading bass loading. It was in their bedside radios, boom box like stereos, etc. I am unaware of any difference between waveguide bass loading and transmission line. Yet they got a patent. I'm dumbfounded as to what the difference might be...

What I've never gotten an answer to is how Bose could patent "waveguide" when it clearly is a transmission line.
