Magical upper mid driver?

RHosch · 16th September 2003, 04:34 AM

I'm interested in a smallish midrange that has low distortion and good frequency response extending well into tweeter territory... around the 5k mark. Guess metal cones are out...

The Seas Excel 5" poly-cone looks promising. Any other contenders I should take a look at?

Hi,

From what I've heard the Morel MW series is very good.
Exceptional power-handling as well. Check out the Scan-Speak range as well.

It is used in the the "Andra's". Check this ling out. Might help.

What about using a full-range driver as the mid? rljones just posted a successful design using a Jordan JX92S as the mid-woof.

I'd look at the 100mm Audax aerogel. I don't remember the number offhand, but they've got one with an f₃ of something like 300 Hz that has a great upper midrange sound. HM100Z0, maybe?

Hi,

Here is the HM100Z2. Disadvantage of 10 cm speakers is their relative low efficiency. You can better go for the HM130Z10 or eventually the HM130Z12. These have a very smooth roll-off at the upper end and are also modest priced.

Cheers

Hi RHosch,
The Vifa P13W can go a bit lower than 300 Hz and does go up and beyond 5 KHz. In fact it is probably a good unit to be used in a 1st order crossover system. You will hav eto find a matching tweeter. I think a Vifa tweeter crossed over at 5K or higher could also possibly manage a 1 st order filter - but I think there are others better in this application.
If the Vifa had cost much more I guess more people would look at it ! It's not the best, but really great value for money.
Cheers.

Pjotr, the HM100Z0 version has higher sensitivity, at the expense of a higher f₃. http://www.cadaudio.dk/hm100z0.htm

Disadvantage of the '130s is worse dispersion at 5kHz.

Try and find s couple of the old JBL LE5-2. They have the old AlNiCo magnet structure, are very efficient, and have a HUGE frequency range. I've got a couple myself, and they are the best mid's I have ever used.

Cheers,
Zach

Yes... I'm looking for something appropriate with a 1st order crossover. Obviously, a low XO point for the tweeter is a serious problem, so I need a mid that blends well with low distortion in that ~5kHz range... naturally, I also need a tweeter to compliment, but those seem to be a bit easier to find.

Efficiency isn't really a concern, nor is low end response. This design is leaning towards a 4-way, due to the 1st order filters, so there will be a woofer ready to take over as the frequency drops below ~1kHz.

All very rough and conceptual ATM, just trying to make a thorough survey of candidate drivers to evaluate just what my options really are. Thanks for the suggestions!
