Welcome to any and all who take the time to drop by!
Wayne was kind enough to get me up and running here, and what can I say but THANK YOU!
It's an honor to be on this board with you, Wayne. And an honor to be alongside Bob, Bob, Eric, and David.
For those who don't know me, I'm a speaker builder hobbyist (started in 1979) turned high-end audio dealer (as of about six years ago), and now I'm returning to my roots but this time as a fledgling manufacturer. So I'm here as a newbie speaker manufacturer, not as a dealer (though frankly it's the dealer thing that pays the bills at this point).
I was hoping to introduce a speaker I've been working on (my second commercial effort) at the Great Plains Audio Fest a couple of months ago, but the cabinets that were delivered to me weren't ready for primetime so rather than make a bad first impression I didn't show. If all goes well, a picture of my speakers should appear above. If not, here's the link:

The image came out a little dark. That's a 10" diameter round waveguide up top, with a 10" woofer below it, and then a 4" diameter flared port at the bottom. Drivers are pretty good stuff - that's a TAD alnico magnet woofer, and the compression driver is a B&C neodymium magnet unit.
Note also the exclusive Romulon speaker cables, with cloaking device "engaged".
Seriously, what I'm trying to do with this design is combine good dynamics and good spectral balance (for the reverberant as well as first-arrival sound) with decent WAF. This will probably be the only one of my commercial efforts that is significantly WAF-conscious.
I will have a professional loudspeaker design & testing company make some publication-quality measurements for me in August. Estimated efficiency is 92-93 dB (8 ohm load); estimated bass extension is -3 dB at 37 Hz; and treble extension is up to about 18 kHz. Dimensions are 42 inches tall by 13.5 inches wide by 16 inches deep, and weight is around 125 pounds each. I calculate output up to about 110 dB with less than 1 dB of compression. Higher peaks (up to about 115 dB) are possible but aren't really what the speaker was designed for.
The name I have chosen is the Jazz Modules. I figure they have sufficient bass extension and dynamic capability to do justice to jazz and non-synthesizer rock music without compressing the peaks up to fairly loud listening levels.
Actually, I have several other speaker designs in the works, and later today it's off to the workshop to sacrifice a perfectly good sheet of plywood.
I see several possible market niches here and there, and hope to fill a few of them.
In future posts I'll probably go off and rant a bit about my ideas on loudspeaker design, but I'll try hard not to be overly commercial. I will try to keep with the tone Wayne has set at this site, though I will fall far short of him as an educator. Any and all questions are fair game, though some things (such as crossover design details) won't be given out. I hope you understand.
May the audio gods smile on you.
