Morel Ultimate UW 1258 12" Subwoofer
Morel Ultimate UW 1258 12" Subwoofer is rated 4.3333 out of 5 by 3.
Rated 3 out of 5 by from the perfect subwoofer with one major flawThis subwoofer is amazing in every shape and form. It's constructed well and generously given a enormous voice coil and can withstand massive power for its size high quality construction beautifully formed but there's one major flaw in my opinion! Given that I have the box that included free with the purchase of the sub, the box that was given, is too small!!!!! they shouldn't even give that box that's stupid. my issue with this speaker is that the spider suspension system is extremely weak causing the speaker to bottom at even less than 500 watts. the speaker will bottom out after 300 watts RMS which makes this speaker extremely weak. no I have not built a box that is compliant which will come in the future but I'm dissatisfied with the performance of the woofer.

Rated 5 out of 5 by from Best SQ sub I've ever heardI purchased this driver and am using it with a 1.5 ft^3 enclosure and 1 LB of daycron fibers. The box was a snap to assemble and finished nicely. The sound quality of this thing is phenomenal. The bass is real and not the slightest bit boomy. I am powering it with a QSC 1450, which will do 900 watts continuous at 8 ohms, which might be a little overkill, but this thing needs lots of power for good head room. I am going to be purchasing an additional woofer, box and amplifier within the next month.When I say best sub I've ever heard; I mean it. It sounds better than anything in Martin Logan's or Paradigm's line up. Very happy, and completely recommend.

Rated 5 out of 5 by from Best subwoofer I have ever heardI bought the UW1258 with the knock-down 1.5 cu ft cabinet and 1 lb of acousta-stuff. Powered it with the Dayton Audio SPA500. The amp leds show that I am getting a bit of clipping at high gain, but not noticeable to the ear. I compared this sealed subwoofer to my ported HSU VTF-3 MK2, using the HSU test CD. I'm happy to say that the Morel sounds fantastic, clearly better than the HSU. Given that the Morel combo is more expensive than the HSU, that should be expected. But, often in life you don't get a better product just because you spend more money. In this instance, I clearly did, and I am very happy with this subwoofer. I would highly recommend it.

Possible sealed and vented enclosure recommendations

What are the recommended enclosure sizes?
Asked by: cavemanmusic
The recommended enclosure for this woofer is sealed at 2 cubic feet. If you wanted to go vented, it would have to be 5.25 cubic feet net with a 4" diameter, 17" long port for a tuning frequency of 18 Hz.
