Did you ever dreamed of owning one of those overprised high end speakers but your common sense couldn't justify the cost (I'm not saying that you just simply couldn't afford them😉 ). I was trying to deal with that and in 1996 decided to built my own version of those original and expensive speakers. I was using them for a year and when my interest turned into an open baffle designs those went into storage.

I've seen recently some other designs on a net. My version used Accuton ceramic mids and tweeter and Focal in the back. It also shares the most important aspect of the original design in that each driver can be phase adjusted by moving it back and forward. The enclosures are made from MDF and since Accuton drivers are sealed the cavity is filled with sand for damping. The finish is done with many coats of auto metallic paint. The bases which support the drivers boxes are made of 1/2" anodized aluminum. Sides made of wood and covered by grill cloth.

I never had a proper enclosure for bass. If I woud finish those speakers I woul probably use 2 Cabasse 8" woofers in bass-reflex enclosure and I even have 4 of those drivers. That configuration is one of D'Appolito project and was published by Zalytron. But I abandonded that project in favor of more efficient open baffle designs. I only have those head assemblies and I'm puting them for sale in Trade section. Anyone interested can find more info there.🙂

I found an older picture how the rest used to look. While not exactly reminder of an original it was quite satisfying. I modified my original subwoofer with two 12" Vietas in push-pull config by adding mid-bass inclosure on top (matrix cabinet with 8" Cabasse woofer).

Hehehe.. Wilson Audio X-1 Grand SLAMM..
I had privilege to help putting them together and burn them in... 😎
Our first listening session was dissapointing.. We all knew that it takes time till x-over and speakers are propperly build, but still we expected much more from speaker that costed over 150.000 dutch guilders (about 65-70.000 bucks American) That all setup amps,( Krells, Tetha CD drive and convertor and SME 30 turntable) costed small fortune.. It took them a month to finaly come to life.. But once they did, boy you had to hear them..
But I agree with you.. They are greatly overprised..

I would like to post some pics from my set, but I can't find host that allows hot linking.. 🙁
