The most important thing was to have the woofer integrate with the mids seamlessly.

too many octaves not a chance!,good quality woofers focus only on bass

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

You are referring to big woofers as 15'', what Dave mentioned is able get from 8'' or 6'' woofers as usually used in Europe, sorry the redundance :lol:

I am scheduled to go to RMAF and if I have a chance I'll try and get a listen.

Sounds good.  :thumb:

Unfortunately I won't be at RMAF but I live pretty close, about 30-40 min away. RMAF doesn't have a suitable room available and I may not get the final protos done in time anyways, I am looking for a different wood shop right now and may have found a great fit, the owner is into HiFi and builds musical instruments too. But I don't mind demoing the rough protos, they don't look nice but they sound ok... ;)

Whatever anyone thinks is best, is good, everyone has different views on what wants to achieve,i appologise to dave and what his science behind that is..

thank you FRM for being like a friend to me

cheers

I just read this thread for the first time and your photo bucket pictures are gone as usual.

Can't you just post some pictures on your own?

I would like to see what you are up to, especially if it looks like porn :lol:

Yea, no one wants to pay the $50+ to upgrade Photobucket. Me too.
Just post in the gallery and upload to here to get around it.

Jam em up upload this to the Bucket Server 1000 times. The owner of da bucket.

If it will help, here is an artists rendering of what the speakers might look like:

Pretty close... the thunderbolts will now be painted on the horns, which will be made out of a cone of the finest cardboard and the latest tech in "invisible" scotch tape!

Unbelievably, pricing will be UNDER 6-FIGURES!  :icon_twisted:

I'm still in the shock and denial phase of my break-up with photobucket. I'll work through it and get some photos up soon...  :wink:

Just so folks aren't disappointed I have not and will not (yet) post pics of the entire speaker until final prototypes are done, and I'm in the process of finding another shop to partner with to build the speakers after the last one proved to be a disappointment. Between this and dealing with branding, marketing, etc. the actual design of the speaker is the easy part!

Just a reminder... if anyone wants to stop by while RMAF is going on I'm about 35 min away in Lafayette. I'll be home about an hour after RMAF is finished for the day Friday through Sunday. I can also be around Friday morning as RMAF starts at noon unless you have a press pass. Espresso drinks will be available Friday morning and beer/drinks after rmaf.  :)

The speakers have 15" AE woofers, 4.5" custom Omega midrange drivers in 330 Hz Le Cleac'h horns and Fostex T500A MkII tweeters. ~102 dB efficiency, active bass <400 Hz.

Amp is a 2 chassis EL34 SET with 6SL7/6SN7 driver section with it's own power supply. LDR preamp. Digital server source, bring tunes however you like, I can rip/load them.

PM me or email dave at zenwaveaudio.com

Hey guys, thanks for your interest!

Well, it's still going forward, the only reason it isn't out yet is due to how busy things have been, and also how difficult things have been in the last year and half.

It's mostly good news, I've been super busy making cables. I tried to hire help but training people is more difficult than I thought. The cables I make generally don't use conventional wire or very simple geometries and thus are very time consuming and difficult to assemble vs a "normal" cable. It's like if you're a carpenter and need to hire an apprentice, yet you're the only carpenter in town and you can't find anyone with any experience whatsoever. Also, due to seasonal variation in orders it's not possible to hire someone as a permanent full-timer quite yet, so I'm in that spot where I have to do more work than I'd really like to in order to get past this hump and be able to hire full time help.

On the bad news, it's probably similar to everyone else, I got covid (twice), my parents got it, my mom fell and broke her pelvis, my dad had both a shoulder and a hip full replacement in the last year. I had major shoulder surgery for a broken glenoid almost exactly 1 year ago, which makes building cables much more difficult! After trying to train help I suffered from intense burn-out. I love what I do and wouldn't trade it for anything but that doesn't mean things are always easy and the workload + isolation + sickness and injury have simply crushed me. I fell behind in both lead times as well as answering emails and everything else.

Ok, that out of the way I have some updates on a few things:

I have made a composite mold for the horn with 180 degree roll-back and it's AWESOME. This is going to be a big advantage over the horns that only have a 90 degree rollback, the 180 roll reduces diffraction and removes one more issue that makes the speaker identifiable as a horn. Now, I think if you couldn't see the speaker you'd have absolutely no clue what it is. It doesn't sound like a horn, or a box, or a dipole... IMO it has the least amount of distortion and diffraction vs most any other speaker type. The horn will also be made out of a CLD (Constrained Layer Damping) sandwich using basalt fiber and the damping layer will be foam used in aerospace applications for exactly this purpose, which will further reduce the contribution of the horn to the sound. Pic of the composites mold below.

On cables, I have a new prototype UPOCC silver IC cable. I've finally managed to completely do away with a plastic or enamel dielectric! In the past I've tried to do this by filling teflon tubes with inert gas, but sealing such a tube is impossible long-term given it's used as an actual cable than needs to flex, etc. My current solution is to plate the wire with graphene. REAL graphene that's very strongly bonded to the surface of the wire, not just graphite dust like most folks who claim to use graphene use. The prototype uses cotton insulation but the final may use silk. The graphene prevents corrosion and seems so far to have no effect on the sound, so the result is a wire that will not corrode and has HALF the dielectric absorption as a converntional teflon wire. This is a game changer and will make for a cable that is, AFAIK, the most technically advanced and ideal IC cable on the market in terms of technical specifications. Add to this a BRAND NEW GEOMETRY that has the noise rejection of star-quad with the capacitance of a litz braid.

I can make this same cable using silver/gold wire as well. So in the near future I'll announce the pure silver cable, then I'll follow up with two silver/gold version for those who want to add some warmth.

Here's the composite mold for the LeCleach 320 Hz horn:

Thanks for the update.  I'm pumped to learn more about the speaker as it develops!
