Paul Stubblebine was in for a listen yesterday. Both mastering rooms at the old 1340 mission studio had front walls that were treated in a similar manner to mine (or, rather, mine is treated similar to what Paul did at the suggestion of Bob Hodas). He was chuckling because their modeling and measurements came up with the same solution of speakers near the front wall. He was remembering armchair experts telling him that was not the right place for the speakers - without ever being in the room.

Overall the new speakers were sounding very good. There is one little bump around 300Hz that I want to address. I need to do some more measurements because I don't know if the bump is in the speaker response (like a cabinet resonance) or if it is a room mode. The next prototype cabinets will be here in a bit. They are baltic birch rather than MDF, and that may have some influence on the bump I am hearing.

I was at BH Monday of this week and listened to the new speakers for a while with Dan.  They sound very good and image extremely well, even better then his big system.  Best of all they sound great with BH gear.

I absolutely love the fact that you guys have gone from your amazing "Wall o' Amps and Stacks o' Speakers," to 3 Kaijus and a pair of (seemingly) simple tower speakers, and you seem to be getting better results.  Shows that in the world of tube audio, there's still plenty of room for improvement.

Well done guys!  :)

I said the same thing to Dan.  The system currently looks like something an average hobbyist could easily fit in their home. 

BTW, if it hasn't been said before, the bass output of the new speakers is impressive.

Here are a couple of pics of the meet setup. First is the speaker setup, with the speakers near the well treated front wall. Response is smooth down to the mid-low 30s in the this position and imaging is great.

Second picture is of one Big Betty quad SE 6550 prototype amp. 50 watts.


Having only recently built my very first simple crossover I couldnt help but notice and being impressed by what I am guessing are the new speakers very complex and large looking crossovers on the floor at the rear of the pic!

Yes indeed. Both woofers and tweeters are equalized (total 4 components for the tweeter and 10 for the woofers); the crossover itself has another 5 components.
