A couple HIGH end drivers tested, data

[DoubleTap]

Just wanted to share data for the Acoustic Elegance TD10M, and Beyma TPL-150/H. A couple very expensive drivers, but measurements bear out just what you're getting for all that jack. Ridiculously good measured performance, and both were taken at blood-curdlingly high levels.

BTW, these are the drivers I'm using for a new design called Arcus. Cabinets are a translam construction with phenolic baffles and the entire cabinet skinned with .030" sheet aluminum. The proverbial brick $hit house.

Wow those measure pretty well, I remember you comparing that planar (??) to the "r-word" :p models once in another thread. I can't wait to see what you come up with!

Re: A couple HIGH end drivers tested, data

On-axis measurements are well and good, but the on-axis radiation of a speaker such a tiny fraction of what's heard in a typical listening position in a typical room that the outsized importance people place on them puzzles me.

How well does the waveguide on that Beyma driver hold its pattern, and how low does it do so?

That should make for a pretty sweet build. Is this a spec build or what? Will we be privy to some of the build details?

Well, today we had the Arcus wired up with alligator clips and parts on the floor.

Wow! Did I say wow? I mean WOW!!!!! :eek:

The dynamics of this setup are just dangerous. :D

We got to spend a couple hours listening tonight between iterations of the crossover. 2 parts for the woofer XO, and another 7 to force that tweeter into a flat response. But what a result. That AMT from Beyma is really something. Effortless output to the XO point, to the incredible AE TD10M. 1100Hz LR4 and a deep reverse null (over 20dB). +-1.5dB from 100Hz on up to 20KHz.

Huge soundstage and breathtaking impact. No bass below 50Hz, but they'll be used with a massive sub when they reach their new home in California. Left, Center and Right. And the owner will have 200W pushing them!!!! Ryan needs to put a warning label on these for people with more than 50W on hand.

We were using them tonight with a tube amp running triode mode and pushing maybe 40W peaks. We didn't even come close to reaching the amp's RMS capabilities and it was already louder than I ever listen to music myself. I don't ever remember hearing anything like these. Talk about FUN!

The AMT is pretty nice. If the larger AC Aerostriction tweeters are anything like this Beyma, they'd make the tweeter of choice for someone looking for those ribbon dynamics with the ability to cross below 2000Hz. It's not quite as smooth and revealing as the RAAL standard, but it's darn close (should be for $500 each). The sound is very involving, with LOTs of attack and crisp highs that aren't "etched." The transparency of the AE/Beyma combo is really amazing.

If anyone is in the St. Louis area over the next few weeks and wants to get an earful of these two expensive and awesome drivers, let us know.

How dare you post positive remarks for such high priced drivers....don't you know that DIY has to always be about the best deal/lowest price drivers?

Beside, too much more info about the Beyma TPL on here and the Raal tag bomber might have to add the Beyma to his arsenal!

Can't wait to see the finished product. You guys do immaculate work.

Wow indeed.

Re: A couple HIGH end drivers tested, data

Slightly off topic, so I apologize, but would it be accurate to say that ribbon tweeters are inherently "better" than a dome tweeter?

Re: A couple HIGH end drivers tested, data

p.s. in the time it took my to post that "the mad tagger" added Beyma to this thread lol

Re: A couple HIGH end drivers tested, data

I'm curious how the CSS Planar2 stacks up to the Beyma..

Re: A couple HIGH end drivers tested, data

I'm curious how the CSS Planar2 stacks up to the Beyma..

Just from published specs, it can't even carry water for the TPL150, which effortlessly crosses over at 1KHz, while the recommended XO for the planar2 is 2000Hz.

Now THIS might give the TPL a run for the money in an application like the Arcus.

DT,

If I may ask, what was the thought in using the TD10M instead of any of the other TD10's, better sensitivity to match up with the top end? Also, have you tried any TD's with the Apollo upgrade? Thanks.

The 10M was chosen for sensitivity. Low end is being taken care of by some massive subwoofers.

These are the only AE Lambda woofers we've tried so far.

Last night, we did talk about using a pair of TD10S for low end duty with an active EQ in a sealed enclosure as a bass bin for the Arcus.

As for Apollo, I don't think that upgrade is included, but I'll verify tonight. The low distortion from this AE woofer is redonkulus already.

Pete,

Thank you very much for the reply. I just find it interesting to see why a designer goes with a certain model in their speakers.

To bad John is not getting the AV line out at this time as that would be an intersting sub to pair with these.

Re: A couple HIGH end drivers tested, data

You guys get these on the group buy. I wish I could have. The Bayma is awesome. To rich for my blood, but awesome to see someone use it.
