Since I had already ordered parts for the original version of the Manzanita I thought I would cobble them together and give them a listen. I used some 1.25" thick ply I had on hand and covered them with some cork underlayment. I love my local used building materials store!

Of course the first thing I did was play them as loudly as I could with bass heavy music and a 120wpc class D amp. I'm amazed at the bass these can produce, I was half expecting them to sound rather thin. I did find the limits of low end with some Pantha du Prince played at loud levels. Bass quality was excellent and as extended as I could have hoped for. Admittedly these levels were much louder than I normally listen. In fact, the best sound so far played at my normal listening levels has been with a passive pre and PP 6BQ5 amp. I only listen about 7 feet from the speakers and don't crank it so the match is superb. I can't wait for the next iterations to be rolled out Here is a picture in my messy garage

Indeed most excellent! And 1.25" ply and cork rulz. Thanks for the photo and the description.

No, these are not a thin and dainty OBees. These rock, for sure.

The cork made it very easy to countersink the tweeter; I just used Super 77 to mount the cork, rough cut the holes for the tweeters and traced around the tweeter baffle on the cork. Then it was simply a matter of cutting the circle and peeling back the cork for the 1/8" recess.

To say I'm eager to see the high efficiency version would be an understatement I'd like something that plays nicely with a SE 2A3 and it sounds like it might fit the bill.

Up close and at reasonable levels, it should.

Yep

Top shelf is pair of EV 12trxb's, next down is a Bogen CHB100 I'm rebuilding into a bass amp for a friend and on the bottom is a Sherwood S8000II.

Right now I'm listening to Buddy Rich on the Manzanitas with a little rebuilt PP 6bq5 Fisher console amp and it is sounding very nice indeed
