This should be well known by now.

Those 4x 15" bass must sound awesome.
Hmmmm........ I don't see that one at the GR web-site any longer. To bad because it looks to be a worthy piece of gear. Of course if I really wanted to build something like that I'd just knock together my own version anyway. That way I could spend the next couple of years and twice as much $$$ to get it running right!
It's still available, it hasn't made it to the website yet. I built a pair (V1) and it is an oustanding speaker, I love it! Here's a pic of mine:

What about the top end? CD fires forward, dome tweeter backwards. Don't know if that matters at all.
Dynamics? Yes. But guessing that Orions would sound more refined.
How does a coax with a CD work anyway? Does the woofer cone provide horn loading?

They are 12" servo drivers made for Danny. Still sound killer. Maybe the best bass in the whole RMAF in 2009.

My WAF friendly OBs solid Camphour Laurel 65mm thick, Pioneer B20 with camphour laurel phase plugs and Dayton tweeter, 2x15in subs in the corner give them some help in the lower frequencies.
Upstairs system
sides are 70mm thick Victorian Ash with MDF baffle, soon to be covered in black fabric, 2x15in GRS woofers per side do suprisingly well considering their price very tight clear bass, Tang Band W4 1337 handles the important parts of the frequency band and a Dayton tweeter handles 8500Hz and up.
These will be offered for sale once I've sorted the crossover.

And they smell nice as well🙂
The camphor laurel looks very good and of course there's nothing better than a dead camphor laurel. If you want to know why follow the link, 57 reasons why camphor laurels must go

Yes it is. 15NDL76. As far as making bass, not well at all. Midbass though, great! Takes twice the EQ of the AE Dipole 15 to get half the results, but that's OK cause it blends well with the Rythmiks. Once I decided on using the Rythmik servos with the project, I wanted to get rid of the AE Dipole 15s. No sense using them from only 60-300Hz.

An externally hosted image should be here but it was not working when we last tested it.

I have a small question. Is it possible to us a half sphere for an open baffle project?
I've seen some spherical speakers made from ikea bowls wich looked great to be honest for the cost. I plan on doing the same thing but i'm an open baffle adept(for now atleast).
Thank you and sorry for being off-topic.
