Morel CAW 538 5" Cast Frame Woofer is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Center Channel par excellenceMad about these Morel raw drivers !! they are an outstanding choice for DIY projects such as HT ... This time I built a custom center channel with these and the Dayton PT2C-8 ... Using the sealed volume for each driver and the result is ...well I would put it up against the $1300 Klipsch RC 64 ll any day of the week ...You will not be in any way disapointed with Morel drivers.... Yes quality costs more .... but going cheap and sacrificing sound quality is not an option.... would like to have used the larger Morel woofers but was confined to a given space....

Rated 5 out of 5 by from great misrange worth the pricealways wanted to try morel and im extremely happy with the performance. midrange is great im using it from about 120 to 3.5 and its great. ruler flat to about 5k. im not sure why some people complain about morels but they sound very nice and the hd is pretty low all thrioughout. power handling is better than other woofers same size. i like it better than usher 7 inch woofers even when used in comparable frequency ranges. great for a 3 way. next is scm version, very expensive but should be even better w low le. will definelty use it again.

what amplifier would be a good match for this woofer?

Asked by: javz
If this will be used as a woofer with no high pass filter you will not need anymore than 100 watts at 8 ohms. If you will have a high pass to limit the amount of low end and cone excursion it will handle more, however it is likely not required.

How is bass performance ?

I am thinking of installing two of these in separate .26^3ft sealed enclosures. What kind of bass can I expect at this price point? I am not really that familiar with Morel, and I would like to know if this speaker is far more superior than a Tang band W5-1138SM or dayton of similar size and specs .I am mostly interested in obtaining tight bass, with good transient response. SPL is not really an issue, Sq is more important.Thanks
Asked by: btucker
Its been a few years since Ive used any, but Morel has a VERY excellent reputation for SQ. They make or supply drivers for high-end ($$$$) speaker manufacturers, quality stuff!
