Default Meridian DSP3200 full range driver identification

Trying to identify what driver Meridian have chosen to use in their new DSP3200 speakers:

Click the image to open in full size.

Unusually it's a full range unit, stated 85mm, looks suspiciously like a Tangband W3-317SC but if you look closely there are some minor differences on the edge.

Anyone got any ideas as to what driver this is?

I'd be surprised if their using an off the shelf driver. If their going to the expense of modifying the mold to emboss their brand they've likely made a few tweaks to the driver as well.

You can view a cross section view of the speaker here:

But yes if you take the cone of the W3-317SC and the magnet and basket of the W3-881SJ you get a similar looking driver.

Oh yes, i didn't see that but it does say meridian at the sides of the driver faceplate.

I suspect you are very correct that the mods are more than superficial. Perhaps they worked with Tangband to modify the driver to suit. That's if it is indeed based on a Tangband product at all. I don't know anything else that looks quite so similar.

I suppose i should also refer to it as "wide" band and not "full" range. Thanks for that pdf by the way.

I'm tempted to take this speaker as inspiration for a DIY project. I hadn't seriously considered a wide band driver like that for the high end. I reckon in this case the only way Meridian was able to make the most of such a driver is by using the DSP to counteract those elements that would otherwise be unsatisfactory. Though the FR plots are remarkably flat for the Tangband driver.

An interesting speaker for sure.

Onboard Digital Signal Processing for dynamic bass protection
Sounds like the DSP has built in subsonic filter and crossover, and loudness control. Also with the bass driver being sealed a little bit of bass boost is likely. It'll be interesting to see how much (if any) eq they are using on the wide range driver.

Have you got a link to the FR plots?

From the propaganda sheet, XO should be <300 Hz, so this is one of the 1st commercial FAST systems. Kudo's to Meridian if that is the case.
