Danny, Can I get the first set of X-Otica's when the kit is available?

Yes.

This was a design pic from way back when...not sure how much will be changed -

That's funny...

Really though. Imagine this design (three servo 8's) with an MTM above it using my new drivers and tweeter in a wave guide.

Three servos? Wow, could be something amazing.

Thanks Chip! Now that is a cool looking speaker.

Danny, is this going to look anything like the new speaker and since it's mostly open baffle will it still need to be 3' from the front wall?

All open baffle speakers need to be at least three feet out from a wall.

New drivers for the MTM? As in Neo 10?  :drool:

So how far along are the X-Otica's in the design phase? Any thoretical measurements? REAL measurements?  :thumb:

No, the 6.5" woofers on page one that were designed for open baffles.

I am still working out details on who will make the wave guides. And I am waiting on the new servo amps for the 8" woofers.

Yes.

OK done. I am sure we can come up with the center to match the timbre by the time the kit ships.

With the flexibility of the subs and X-Otica's servo amps I should be able to dial it in with the least amount of room treaments needed. Am I correct on this?

It also seems I will be able to control the level of SPL so the system will be balanced between Music and HT once it is adjusted.

Jon, will be close enough so hopefully we can have a shootout between the X-Otica and his full range driver with the servo subs. That would be fun.

Now the hard part is the wait but I can stay busy till then.

It would be simple to build too.  Am I right, no boxes to be built?

No, these drivers would not be suitable for those applications.

So is the M130/165 on par with these new drivers, open baffle applicability aside?

Like all of our drivers these new drivers were designed for a specific application. And in this case to be the best drivers ever designed for those applications (open baffle). Comparing them to other drivers used in other applications wouldn't be an apples to apples comparison.

Danny:

What are the design elements that make a driver especially suited for OB?

Thanks, and Merry Christmas!

Electrical and mechanical parameters are very different for open baffle designs.
