Theoretical Concepts - How It Began

I have designed speakers for years. Even before the first "computer" the Radio Shack TRS-80	Early designs - V3.0 subwoofer - flat to 18 Hz	An old crossover from scratch. Home theater in background.	V 6.0 Theoretical work
	Some satellite ideas	Final idea	Imaginary speaker placement

CONSTRUCTION

Edge-on view. Each groove cut within 1/16" of veneer	All 28 grooves exactly parallel...and 6' long	Rounded edges mean no diffraction - the speaker will sound like is has no edge.	Time for a Reddi-Whip break
Testing and breaking in drivers	Glue drying on internal braces	Followed by Dynamat tar, layers of acoustical tile and deadening foam adherent.	Cavity is triangular. My "Acoustical Coffin Theory". 10-gauge 1,064-strand wire is silver soldered. Finally, stuffing is long-haired lamb's wool.
Drivers float on rubber gaskets and grommets	High amperage connections	Fused @ 800 watts	Comparison of 15 year-old V 5.1 and the new V 6.0. (Home theater in-wall in background.)

FINAL RESULT

In background, one of two special order, modified, Klipschorn subwoofers.	Listening Tests	Helper collapses after we position the v 6.0 (scale broke at 400+ lbs.)	The V 6.0 is finally done!
Final position resembles the virtual placement (above).	Power amps. Triamplified.	The electronic crossover. Homemade - to achieve one clear enough.	The speakers reveal defects even in my Jeff Rowland preamp, so it was modified.

Why this home audio project? After attending the National Audio Show in Chicago, I heard the Radialstrathers ($35,000/pair). They sounded nearly as good as my 15 year-old v.5.1 design. Too close for comfort! (The $95,000 Dynaudio was nice, but second to the R/S.) I had extra gold GRC ribbon drivers stored, so I got out my pencil and started engineering.

The results exceeded my expectations. The sound is so lifelike it is spooky. When hearing vocals, is it hard to hold a conversation because it sounds like someone is in the room. Well because, they virtually are there.

So, as with the performance car project, home construction, laser research, or microsurgery, I did this is simply to see if it could be done. Since then, I have not heard anything better. You are welcome to make any comparisons. I am always looking around. (Hehe.)

I hope you enjoyed the website. Let me know if I can improve it. Off to another project.....

An airbearing turntable - in all three axis, X, Y, and Z. Here

Racing car videos are also Here and Here Have fun!

Most importantly - Don't forget to play the music!
