hi i,m thinking of purchaseing the morel elate comps. 9/5/ tweet set but wish to use the supremo tweeter.

has any one had experiance with the above and what are your recomendations for x over

cheers jamie @ liquid ice ( UK)

you can use the morel mx33 crossover. its made for use with either the mt-22 (or mt-23 i can't remember which is the new one) or the supremo tweeter.

if you read the spec sheet for elates on the morel website you will find that both tweeters are 6ohm impedences.

or you could go active for them. what i've found is that they certainly like power. running the crossover in bi-amped form giving the mid/tweet and the woofer 75wrms from a JL amp was good, but midbass lacking a little. after briding the amp (150wrms) and just running the crossover normally the midbass had picked up alot.

I tried having the elate 6's and xover with the supremo tweeter, i HAD to biamp, as i needed a 10db drop (actually about 11db drop) on the tweeter..... the xover's have the right xover point, but the sensitivity of the supremo is MUCH MUCH greater in real life.... I run a 70x2 to the tweeters and 230x2 to the mids, they seem to like that a little!

10dB, that sounds like a little (huge) bit of an exaggeration. (the difference between 70w and 230w is only about 5dB also...)

The Supremo and mt-23 are both 6 ohm and the measured sensitivity (according to Morel) of the Supremo is only 1dB higher. The supremo also has a lower Fs.. As PartyJase suggested, I guess you could use the mx33, or use active filters and multiple channels of amplification.

But (in reply to Nutttr) if there is a significant difference in sensitivity, then why not just add your own L-pad (and a Zobel to account for the inductance) to the tweeters to reduce the sensitivity to match?

I did make a l-pad.... although using 5w resistors i had to use a 4 to make the correct end result, and it got to the point where i needed to adjust it 0.1ohm and it made 1db of difference, it was beyond doable without proper testing equipment, i tried them and they worked, not very well, biamping was 100x easier to setup and use.... My L-pad was a 10db drop at the end and measured the same as the tweeters by themselves... I have the MX33 xover's and they work well for xover point, but they (MT-23's) must either be very bright or sound ok and the supremo's are a lot more sensitive.... I'm not kidding about the -10db either, it really was setup that way in order to make it close to "flat"......

since the mx-33 is a pretty flexible crossover (-2,0,+2db settings for mid & tweeter with 12 or 24db crossover slopes) i'd stick with that to start with, and if you find ur unhappy with that or the crossover points don't match want you need in ur car then look active. but theres a lot of options to go through first.
i actually run mt-37 tweets with it which were the top model before the supremo came out and dont have any issues with them at all. sounds excellent and using the supremo can only be better. only prob with a 4" tweeter is mounting can be a real bitch.

also if you run time alignment with a biamped crossover you could delay the mid and tweeter if they're in the kicks, while not worrying about the midbass. obviously you can do that running active aswell.

NUTTR: where do you have the tweets mounted? thought of EQing the tweets freqs rather than an l-pad?

In the sails/kick panels at the time, experimenting with positioning, either spot was too bright.... I wanted to eq them, but didn't have an eq, when i got an eq, i removed the l-pad and had the xovers' on flat and i had -10db drop on the eq settings across teh whole range...... then i biamped and simply set them up
