    Re: Last Hurrahs Build - finally got started

    Ha ha! They are a bit, and the speakers are well over 100# each. So the XO's are in outboard boxes connected via Speakons. The speaker walls are 1.75" thick. Heavily braced. DEAD. Once place, I try not to move them!

    Those crossovers must be HEAVY!

    I declare them done. Here is the XO if anyone is interested. Measures very well. Sounds great. Dynamic, tuneful. Very, very pleasing.

    I really liked the mids in the Malbecs. That was really refined and CLEAN. CA18's are indeed no slouch, but I've not heard those yet. I'd pick the U18 over the W18 for mids.

    My 2c,

    You are correct, Sir! And now, so too, is the link.

    Those are looking great....hope to hear them in the midwest sometime.....six days is a long commitment, but you need a break from the AZ heat sometimes. :p

    I like 3/4" tweeters with their top end sparkle and I find tilting up the last octave on 1"+ domes to help simulate that sound. Up 1 to 2dB at 20k.

    I am not aware of Curt's write up but that sounds exactly like what I did on the last revision of the RUshers and what I'm currently simulating with the new Meniscus drivers that were used in Jeff's seminar.

    I don't know what was going on last night, but I just went through the speakers and disconnected then reconnected everything and - they are making music! Nice music at first listen.

    I am pretty pleased with the first pass XO on initial listening - no measurements yet. I went for a rather strange alignment on the Ushers, placing them in a notably smaller than textbook box, and accepting a more closed-box like response (see Curt Campbell's write up on this approach). Sounds very tuneful and free from boom. Seems like best of both worlds. I may, however, pad down the mid and tweeter a couple of db. However, with the music I know well, and which I know to be good, they seem fine. Time will tell.

    That U18 as a mid, with which I felt some nit-picky disappointment in the Malbecs sounds really, really fine. Wolf was right on them. Eventually, I will rotate in the CA18RLY's to see how they perform, and who knows, I may get into the Excel line before it is over.

    The CSS LD25X tweeters sound very clean. I got a pair with not perfectly matching fs, sadly. Despite sounding very clean, it is immediately clear that they don't have the air and delicacy of the Hiquphons - and I already miss that. I may end up tailoring the XO for each one if they measure differently in the actual application.

    Does anyone have an opinion about the LD22 tweeters? They are about all that will fit the existing cutout if I decide to change.

    You are all invited to Prescott to have a listen. Get out of the cold!

    Last Hurrah, last big speakers. It would be nice to get them to InDIYana or DIYIowa, but the six day commitment to drive them up there is a big one.

    More in a couple of weeks, after some measurement.

    Wow, I hope I can do the Malbec cabs justice, those are STUNNING. I seriously wondered how you were going to top the Malbecs, but no more. I'll hold my hat in my hand any time we speak from now on, sir.

    I want to say more, but I honestly don't have the words.:eek:

    Amazing.

    Now I've done this over 20 times - building new speakers that is. Never, though, have I had sound only from the mid. Too tired to troubleshoot safely, systematically, and effectively just now, and not likely until next week due to travel. So, I wait!

    The cell phone picture does not capture the beauty of the wood. Not waxed yet anyway. Will work on a decent pic later as well They do dominate the space! Beefy boys!

    Really beautiful work maynardg. I'm not a huge fan of oak but your staining work is very nice and I love the shellac for the topcoat. I'm sure the anticipation is killing you. A very nice job.
