ToneSpeak speakers?

I just read about their new bass guitar drivers a few days ago. Seems a few key people left Eminence to start up their own line of musical instrument speakers under Misco's corporate umbrella. I'd be curious to know whether they plan to expand their offerings for bass guitar beyond those already announced.

I was going to say...those look exactly like Eminence speakers!

I see Anthony Lucas is there from Eminence, whom I've had many a good discussion with over the phone. Just going by that I'd say these speakers are legit.

I totally agree. Anthony Lucas has helped me several times over the years by answering my questions about driver identification and providing recommendations.

@Matthijs I'd love to see something with a stronger mid/high voicing similar to the Eminence Deltalite II 2510. I'll be keeping an eye out for new offerings.
 

Never heard of 'm.
I just checked both 10" drivers, the 150 watt model looks pretty good.
The 250 watt model has a huge destructive resonance at 640hz (probably caused by the cone edge), so I would skip that one.

The 2-roll-surround reminds me of the Emi deltalite series, this can be pure coïncidence though.

Do you know the theory behind the resonance and the cone edge? I'd like to add it to my vast storehouse of knowledge. ;)

Most of the time it's the (unwanted) interaction between a (softer) cone and the surround. Both have their own resonance frequency and their own damping characteristics.
A way to make this behavior visible is with laser interferometry. Philips was one of the first to use this technique to optimize their loudspeakers (early 80's), it was mentioned in one of my ol' loudspeaker books from 1986. Most of their woofers from that era had a foam surround but there was a thick black rubber like coating at the transition between the cone and the surround to counteract this problematic behavior.
