My Center, 50 lbs and 1,000 Watts


Gang,

After me waiting six months, my speaker cabinet has arrived and the initial assembly has been completed. How does it sound?  I have no idea, it still can't play a thing. :)

The goal was to make a speaker perform as well as a point source, with vanishing low distortion and extreme (for my living room) dynamic range.

Hey, @soix

I know of no one besides Fritz who can sell a speaker for less than 10x the driver and amp costs, so 12k would be a starting point.

Seriously though, there is no way I think I would enjoy playing in the speaker market. It sounds like a horror show. I feel blessed to be able to take my hobby in this direction right now.

I get super excited by having parts arrive.

Agree 100%. It’s why cable manufacturers show up at audio shows in Ferraris or Porsches with big smiles on their faces while speaker manufactures show up in rented cargo vans all sweaty, stressed, and tired. I can’t even imagine.

Ah, the joys of manufacturing.... after getting all the different types of connectors (3 different metric sizes), and ordering metric hex screws from China that took 2 weeks to arrive I'm finally ready to power up the speaker and...

There is a firmware problem.  For whatever reason the CPU on the amp keeps identifying itself as the wrong model so I can't get the 3rd channel to be recognized.  Hypex is being really responsive but their first patch did not work. 

Here’s an interesting listing for a Wilson, using similar woofers and no midrange. Generally listed new for around $17k. I guess the extra 60lbs of cabinetry really add value. 😃

All joking aside, Wilson, ATC, Legacy and even Troels went a different direction in terms of bass than I did. All of them went for deep extension center channel designs (-3dB @40 Hz) but I went for maximum output. This let me use a much smaller cabinet, but also having measured these drivers before, limits the distortion significantly.

Honestly I see no benefit in trying to make a center channel quasi-full range.  Limit it to 80 Hz as George Lucas intended!

Eric,

Chapeau bas, as the French say. Such audio craftsmanship lends a lot of weight to your posts on this forum—like the added authority a wine maker can bring to a tasting. I always read your posts with interest.
