New Morel drivers: TiCW 634Nd
 
Hey fellas, I just got a notification that Madisound is now carrying the new series of Morel drivers, such as the TiCW 634Nd.


Speaker Building Supplies from Madisound

What does everyone think of them? The response and breakup modes seem very manageable.

Anyone have any usage ideas?

For a second there I thought the cones were going to be made out of Titanium not just that the voice coil former was. I am highly skeptical of Morels claims with regards to the use of the material in that position, it would be interesting to see how the drivers with the copper in the motor perform though.

I think this is a "trickle down" affair with Magico. i.e. Magico spec's things, and Morel makes their drivers to this spec.. After a while Morel starts incorporating this into their own designs. About the only thing I don't think you'll ever see from Morel is Magico's diaphragm design.


As for this driver: to much mass - it's turgidly inefficient.

For this sort of fs and sd I'd like to see about half the mms shown and utilizing a quality foam surround.

I have one in my hand right now. I received it from Russel Kaufman, and I will be testing it soon.

Drivers with huge dia VC's versus Sd tend to have high mms. Never have been a fan of Morel drivers and these large voice coils.

Well then Scott it's just the same as 99% of other 6.5" drivers out there. Obviously this isn't anyone's idea of a higher sensitivity driver. Although I do agree with you, it would be nice to see a few more mid/bass drivers that put more of the focus on the 'mid' part of rather then the 'bass' part.

That will be interesting to see.

It's a 4 ohm driver.

On the other hand the SD is smaller than anticipated - really is more of a 6" driver, so not quite as inefficient as anticipated.

Good looks though. :cool: :p

Even pro units (where it's a lot more common). Bigger coil, bigger former, more mms.

Often a problem with these larger coils is the diameter in relation to the top of their pass-band. (.."break-up" problems.) Who knows though, perhaps the material composition and large center dome structure mitigates it for this particular driver?

Seems to me that using an aviation-style Titanium former has gotta be marginally better than aluminium. :D

Looking at the predecessor 8 ohm version CAW 638 below, I cant help wondering if a targeted notch at 4.4kHz would turn this into an outstanding mid/bass. I make that a shunt of about 12uF, 0.1mH and 2 ohm. BSC coil ought to be about 0.6mH for a wallmounter. I think I made the tweeter filter to be about 4.7uF and 0.2mH with some attenuation. Would almost fancy tuning it by ear. :D

pity the exact Ti alloy isnt mentioned. Marginal weight reduction, offset by huge diameter. Large cost for tiny improvement. Gimmick. Shame they stick to their vague polymer description. Many drivers, all remarkably similar, move on Morel. Puh-lease.
