Amazing! A thread on the internet with GOOD things to say about the 901. I realize this is nearly a year old, but I just dusted off a set of series I, but hte RCA cables at Radio Shack are too big to fit the EQ. Anyone know where I can find the old fashioned style?

Hi Richard - Welcome to Phoenix. I've enclosed a drawing 'cause I'm assuming that the connector ends are too large for the EQ connector spacing but just wanted to make sure. If that's the case a lot of places sell RCA cables with the smaller connector ends - just do a web search for audio RCA cables and you'll get lots of hits.

You must like the 901's. They get bashed by many but they do pack punch and come in a small package. Of course the EQ is necessary do to the flatness of the sound.

Good luck.

Hey Dennis thanks for the response. The guys who can spend seven thousand dollars on Pear speaker cables bash Bose, but I have my house set up 70s bar style; I have a coin-op pool table, a vintage video game cabinet, and lots of early beer-bar memorabilia. My ears are't super particular. Actually, the 901s are playing in the other room, and I am managing not to vomit. A sub and the cables for the EQ, I might even enjoy my $300 investment, and look cool at the same time.

No Dennis they use the EQ to simulate a flat response...
I guess I was looking at it from the EQ side - it has more gain in the low and high end but you're right about that. I visualized the EQ output oscillograph - silly me,

It's amazing what people will pay for stuff.

I like the 70's bar style idea - did you did say beer??????????????

What series EQ is it? Ive never had any issues connecting my series VI EQ, with any wires. I guess the older series jack's are closer together.

What we need

What we need is for Danny Ritchie, or some other talented speaker designer to revisit the Bose 901 concept using the best modern speakers available along with the best speaker design software. I'll bet a well designed and executed 901 clone, using the best (instead of the 69 cent Bose speakers) with an integrated subwoofer might be a pretty awesome system. Like everyone here I owned a pair of 901's driven by a PL 400 in my college days. Other than both the speakers being blown and the amp being blown, and both spending LOTS of time in the shop being repaired and replaced, it was a very nice system. Like Lee, I had a second pair of speakers ( Watkins WS-1A ) that I used to get bass. They had the first dual voice coil woofers (having been designed by Bill Watkins and the patent later being sold to Polk or somebody....can't remember). It was one of the better systems on campus at the time. I later sold the amp and preamp for a Luxman M-4000 and the speaker were replaced by Magnaplanar !!A or something (still have them both)...and no I didn't wire both pairs to the PL. I had a separate amp driving the Bose...Later on, I did use just the PL with the Bose...and a receiver driving the Watkins...I think there may be merit to the direct/reflecting concept, but what do I know...but it would be nice to hear a pair done right...

with a little trial and error you could probably get very close to the above by integrating some decent supertweeters and a sub with the 901's. in my mind the most difficult task would be finding the right tweeter.

Ah, the same dilema I'm having trying different tweets in the K's. I would really like to try a Heil Air Motion Transformer. I heard one years ago and thought that was the ultimate tweet besides the plasmas.

In any case there is still going to be sound coming from 18 points, and all the different reflection points to go along with that. Adding bass is easy since it's omnidirectional, but a single point high frequency tweeter would be tough to cross-over. It's likely easy enough to cross-over a tweeter with the single mid in the front, but the crosspoint would vary and smear with 89% of the back waves relflecting back at you from the rear. That might just mean you'll get a few piano keynotes point sourced while others go into total diffusion.

Using different drivers that don't require active equalization sounds more compelling.

Valid points Joe, but I was thinking of putting a Heil Tweeter on top of the K-Horns...

Doh...! I swear I'm not drinking. Just tired.

Do those actually dial in on the sensitivity scale? Could they be horn loaded ?!?!!
