from Great tweeter used rightIn two projects I've used first the CAT408 and second the CAT378, and overall I like the CAT408 by a small amount. If you need to have the tweeter timed later than a small woofer (my needs), the CAT378 really fits the bill. I highly recommend this driver for almost any project.

from Louder than the older MDT-37!I through a pair of these newer CAT-378's in some cabinets that previously had the older MDT-37's. I measured these to be a little bit smoother in their response. I also found these to be 1 db louder than the MDT-37's. I now need to add 1 db Pads for designs I made using the older MDT-37 drivers. According to Morel the CAT-378's have a higher grade magnet. I am wondering if this is making them a little louder / efficient. I did not know this when I wrote a previous review.

from Good & Wide Sound - Great for Time Alignment!I bought this and mated it to the B&C PS100 with a 24 db / octave LR crossover at 1,320 Hz. Part of the reason for the LR crossover and choosing this driver was to ensure both drivers are in phase with each other at all frequencies. This driver is a shallow horn loaded design. (By surface mounting my B&C PS100 and mounting the face of the CAT378 flush with the cabinet surface, it results in approximately 1mm difference between the two drivers domes for near perfect alignment.) This makes time and phase alignment with this driver by using a LR crossovers in 2-way designs really quite easy. The only RTA measurements I've taken to date in my living room at about 40" away have been very encouraging. In this location with my speaker system design it is +/- 2.5 db from 1.81 - 18.25 kHz in 1/24th octave resolution using TrueRTA software. (I had expected it to be overall strongest in the 3.5 kHz range but found it to actually be in the 8 - 10 kHz for both of my drivers in both speaker locations. Overall it was a more neutral sounding response than I expected based on seeing Morels graphs on their website. A Plus!) I find this driver to sound bigger than it is. In listening I don't think it sounds like the sound is originating from a 1" wide source. Maybe that is because of the shallow horn design. This bigger sound helps make stereo imaging very smooth, very big and wide. (Regardless of the reason it is a definite plus in my book.)Available replacement Domes are a definite plus should you ever accidentally hit play with a powerful amp left in the max position from repair and take out your tweet's. (Speaking from experience, it only takes two snare hits.) They are easy to change on this model and cost much less than completely new drivers.I highly recommend my B&C PS100 / Morel CAT378 / 1.32 kHz. 24 db/octave LR crossover setup. Nice Driver Morel. I'll be using it in my next speaker design as well. Thanks!
