Morel CAT 298 1-1/8" Soft Dome Tweeter
Morel CAT 298 1-1/8" Soft Dome Tweeter is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Smooth Tweeter!I built a center MTM speaker and used 2 Dayton RS150 8 6'and built a Second Order (12db/octave) Two-Way Crossed at 2700HZ. This little tweeter really sounds clear, the highs sound very true and the further you go down in freq. the better they perform...They are used for movies only and they relay exactly what was recorded, voices sound very true and will amaze you! I am still experimenting with them BUT this has proven to be a very nice and versatile tweet!!

Rated 4 out of 5 by from Great replacement tweeterI needed a replacement tweeter for my 30 year old ESS Tempest speaker and this one is an excellent choice. My search lead me to Parts Express where I got very good advice and fast delivery. The cutout had to be altered slightly but otherwise installation was a snap. The sound is as close as my ears can detect to the other (original)speaker, so I am back in business with my old favorites.

I am useing one of these and two Daytons RS150 8 6I have them crossed at 2500hz Second Order (12db/octave) Two-Way Crossover. What would work better?

Asked by: Bret191
Well, you have two very good drivers. Depending on your budget - either go with a 6db/oct crossover, or a full blown 24db/oct crossover - both are in phase and very musical. 12db is the inexpensive way to protect a tweeter but doesn't sound that good... Glad you have the ear to hear it... Use poly caps - 1200 volt, and copper air coils, large gauge... You'll have a hand built crossover that's over-rated to handle peaks and transients without getting over-saturated. I promise - you will hear the capability of you drivers for the first time.

Can I use these for the KEF104.2? Can the faceplate be removed? What is the difference between this and MDT29?

Asked by: larbman
The CAT 298 has been tweaked and improved for better performance. All subtle - but happens with drivers as magnet technology and other things improve - they add them to the new generation of product. The faceplate can be removed however it is an integral part of the drivers performance with regards to dispersion and you would be advised not to do so. As a replacement for the 104.2's - tricky - different impedences and efficiency - plus the KEF is time aligned. I would contact KEF. Another option is to" modify the cabinet and put in a ribbon - something like the Aurum Cantus G2Si Ribbon Tweeter... Good luck with the project !!!
