Morel MDM 55 2-1/8" Soft Dome Midrange
Morel MDM 55 2-1/8" Soft Dome Midrange is rated 4.7143 out of 5 by 7.
Rated 5 out of 5 by from YOU CANNOT ASK FOR MORE CLARITY!!Bought this for my DIY center channel speaker. The clarity is just perfect for the speaker I did and its really loud on sound effects and voices. I paired this with two Dayton RS180 woofers and NeoCD 3.0 ribbon tweeter on the center channel speaker. I compared this with my metal dome mids RS52 on my floor-stands speakers and the difference is a lot. Now I want to buy two more for my other speakers.I recommend to cross this between 1kHz-5kHz and using high quality crossover parts such as Jantzen Z-Capacitors or the Superior series.

Rated 5 out of 5 by from AWESOME CLARITYI've set these up in a 4-way active system from 1K to 5000 with a Carvin hd900 amp driving 'em, THE CLARITY IS AWESOME. On the top I've matched them up with a pair of morel md-30s, and the two together are some of the best I've heard! I HIGHLY RECOMMEND THEM crossed over from 1k-5k!

Rated 4 out of 5 by from A classicOne of the finest mids at any price if used correctly above 1000 hz. Very dynamic device capable of playing very loud and clean. Shines at reproducing electric guitar. Best if combined with larger woofers(12-15") in a higher efficency (90-93db)system. Not recommended for smaller 3-ways. I own 4 of these drivers.

Rated 5 out of 5 by from fine sonicsKeep in mind that this driver is very flat from 1,000 Hz to 5,500 Hz,however it drops off erratically below 1,000 Hz.A designer should plan on using a woofer that is very flat out to 1,200 or 1,500 Hz and cross over no lower than 1,000 Hz. with a second or third-order filter.Very natural sound in that frequency band!

Rated 5 out of 5 by from Nice Midrange speakerNice midrange speaker. My only complaint is the square shape of the front which makes it kind of a pain to flush mount. I would have prefered a circle so I could use circle jig. Sounds great.

Would this work well with a Hi-Vi M8a 8" woofer, and a DC28F "silky" tweeter, in a 3-way system? I would be building a 1.75 cu ft/ported enclosure to house these drivers. If this works, could anyone recommend a pre-made crossover? Thanks!

This Item is rated @ 200 watts RMS. Is this pre or post crossover?

Asked by: Dizz E
I would say this is post crossover. I certainly don't think 200 watts rms would be advisable on this before any crossover.
