I understand if someone doesn't like the CD sound.  Its a tiny bit different sounding to my ears, but I don't much care for most dome tweeters especially when the volume goes up.

FYI, just came across another source of waveguides for dome tweeters if anyone is interested (I'm not, but someone might be).

FYI, if you wanted to play cleanly up high, you should have used the TD12M which is a midrange, the TD12X is a midbass speaker and has a surround resonance at between 500-600hz which shows up in the measurements.  I haven't tried the 2512 or the 2206.

I plan on shipping him some RAALs tomorrow morning to play with.

He also has a pair of the SEOS and DE-250 compression drivers and perhaps when it's warm again will build yet another set of speakers.

There is a second pair of jbl 2226h drivers but one has a voice coil rub, so must be either repaired or replaced.

The SEOS & DE are the ones that are in use now right?  Ruben finished.

Yes, the foam surround of the X causes the midrange FR aberration that is audible in this application. Accordion surrounds don't have the problem, but X was what was available to me at that time.  The 2206 sounded very good, but needed a notch for the cone res, which I did not apply, as I was burned out on the project by then. I'd use 10M if I ever try again. Face is building them with 10M, I am looking forward to his impressions as he has a lot of experience building with high end drivers.  The B&C woofer also sounds excellent in Jason's Abbey's, very clean through the crossover.  The 2512 did not break up, but were more blurred at Fc compared to the others.

Jason: Beyma TPL150 is a pleated tweeter with attached horn, very high sensitivity, very linear FR. Also a nice Z offset to match the woofer.

It is also used in the Vapor Arcus.

A mere $500ea USD for a horn-loaded Heil AMT...let's see now....2 monitors x three Trinaural channels = 6 channels x $500ea = $300 for tweeters...well, a bit more than my Dynaudio Esotec domes @ $200ea anyway.

Seems like an interesting tweeter option though.  Ate lunch with Oskar Heil many many moons ago S of SF down the peninsula somewhere...ESS pulled one of those industry moves like the TV network did to James Garner in Garner's hit TV show: sorry, we're loosing money on this venture and have no royalties to pay you.

That is for the non WG version, the TPL-150H is $580/ea from US Speaker. Ugh. http://www.usspeaker.com/beyma%20tpl150h.htm

Which I'm very much looking forward to hearing one of these days.

I heard the Arcus at Ryans's house a while back and just recently in the system of an audio buddy (simple, sweet system using a Pass integrated with PWD from a MAC). It is an exceptional sounding speaker. The sound is neutral with a flat frequency response and very revealing--so your system needs to be low noise and either neutral or on the sweet side. Adequate bass in a small room but needs a good pair of subs for larger room or full range playback-IMO.

What is the Arcus?  nm...found it.
