    So Dave, what am I supposed to do with my 340's 27mm soft dome tweets with all that mass that has to be moved 12+ windings and the energy it takes to do so now that you convinced me of the superiority of the RAAL at 0.039 g's and radiating area of 13.6 sq cm.???
    Take care my friend, Jeff Nordi

    Thanks for the link to Zaph, some neat stuff over there. Some serious time invested for all those measurements.

Some of the top 'high end' and very highly regarded tweeters are 'plain' soft dome!
    Personally, I don't really care what the tweeters are made out of. I believe that proper implementation is usually more important than the diaphragm composition. What I do care about is that they sound good, measure well, and don't fatigue my ears.

    When I was shopping for loudspeakers, I found that the majority of metal domes gave me ear fatigue, while the majority of soft domes did not. So naturally, I tended to avoid those designs with metal tweeters. Ironically, this appears to conflict with my earlier statement about ignoring diaphragm material. My previous speakers were from Yamaha and had aluminum domes. Here's the kicker: they did not fatigue my ears like other speakers with metal domes I'd tried.

    I agree that some folks can get hung up on the material used in the tweeter. My guess is that Be tweeters are uncommon, so perhaps someone could see that as desirable (e.g. I have a rare design, therefore it is good). If Dave could make a tweeter using Unobtainium, and if it sounded good and measured well, I wouldn't have any problem with that.

    This is definitely the most important decision you'll ever make.

    I haven't heard the 340s yet, but if they're like Ascend's other products, they perform well above their price point. The RAALs are in a completely different class, though. Kinda like the difference between a fast and agile sports car compared to a Formula 1 car.

    I hear you
    I love the 340's, and yes they do perform well above their price point, they replaced Athena F2's and I never looked back, I actually gave the F2's to friend. I used the 170 as mains for awhile to compare with the 340's, very similar sound but just a lot more of it and they dig deep for their size. The only problem is now I want a faster more agile machine, sports car or formula 1 ?

    Keep in mind, that at one point, the CMT-340SE was Ascend's top of the line speaker.

    Yes, I agree that it's no slouch and in my opinion best bang for the buck in the Ascend lineup.

    -- Hi Jeff,

    No worries... and I should make this clear to everyone. Without question, the RAAL ribbons are technically superior transducers when it comes to accuracy. However, this does not mean that they will sound better to you.

    For example, a good customer of ours came by with his lovely wife this afternoon to audition both the ribbon towers and the NrT towers. He already owns Sierra-1 NrT.

    He liked the ribbons and spent perhaps an hour listening to them. We then swapped out the ribbon towers with the NrT towers and they listened for 2 1/2 hours, goosebumps and everything. They went home with a pair of black bamboo NrT towers as this was a sound they were more familiar with and preferred compared to the ribbon versions.

    Even with the technical superiority of our ribbons, it still comes down to what sounds best to you, and your 340's use an exceptional dome tweeter

    I agree, I think best bang for buck in the industry

    Thanks Dave, I needed to hear that, and yes the 340 tweeter is excellent even below and above ear level. I've never heard a pure ribbon and I know I will be very happy when the time comes to order the NrT ST's.
    Cheers Jeff
