My Lambda woofers arrived today.

Pretty much no one but my roomates and my parents know what I'm doing. I have cardboard boxes in the closet and in the corner of the living room, wood in my parents garage, an empty enclosure in my living room, and amps and sound processing equipment in the closet. I have thousands of dollars of audio equipment and barely using any of it. So here's a rough outline of what's going on.

Well a couple weeks ago I put in my order for some Accoustic Elegance Lambda TD15H's with 4 ohm voice coils. They take about a week to build, because they're built to order. Finally, today they arrived.



They do have a giant (around 3-4" long) phase plug in the center as you can see. This helps with the upper end extension/breakup and acts as a heat sink. While pumping 650-700watts into it (the clip lights were lit up), it did get a bit warm, but not too bad.

...Though what is bad, these have so much output in the 40-500hz range where they'll operate, I don't think my dual 15" subs and their 2Kw of power can keep up. I also don't have enough AC power because my lights are dimming when the bass hits. I'm affraid that once I get my system done and all the amps hooked up, I'll trip breakers while rocking out.

My next step is to source some mids and tweets. I do have one tweeter on the way for auditioning and the same company that built my Lambda woofers is building a prototype mid. When they can build a few and do some testing, they may send one out to me for "beta" testing.

*edit* I forgot to say anything about these woofers. Well I put one in a 4ft sealed enclosure with no stuffing (bad move). It let too many reflections through the cone from the backwave, so I had a hard time getting it to sound good. I had to drop my 600-2.5khz area quite a bit, then boosted the 8-15khz area up quite a bit. That's the awesom/crazy thing about these woofers. The combination of the near zero inductance from the lambda motor, the parabolic curve of the cone, the huge phase plug and the anti-resonance spray coating (just a flexible substance that absorbs energy) on the cone allows this 15" woofer to play from 30hz all the way to 16-18khz with some EQ'ing. But again, I'm using this driver as a woofer/midbass so it'll be crossed over at ~500hz.

Excellent sound quality though.

14mm xmax for a mid-bass is nice.

He offers 10's, 12's and 15's. (with 4 different set of soft parts and the option of an apollo motor upgrade)If you order a pair, you get 50.00 off.

14mm xmax for a mid-bass is nice.

Especially a 15" midbass.

...More to come.
