MB Quart tweeters

[Coenlaf]

I have just found MB Quart tweeters (most 1" titanium) on a sale page but the specs and normal price list is not on the page. Does anyone know the value and specs of these tweeters? 95-6738 1" titanium, 95-6934 1" titanium, and 95-6665 1" titanium.
I never heard of this brand, any info would be a help.
thanks

Hello there,

I am an MB Quart finatic and have a huge number of both their car and home speaker sets/drivers/tweeters. I am just in the midst of moving and have everything packed away right now. I will look through my collection within the next week or so and see which ones those numbers that you gave refer to. I am not quite sure off the top of my head. If you are still interested in this information please let me know and I will see what I can do to dig it up for you.

I especially collect MB Quart Tweeters and have a majority of the models of them, at least the higher end (the 1 inch) ones anyways.

1.8k 3rd order??? What do you all think?

Hi
Looked at the plots. Amazing low primary resonance at 550 Hz! WAG rule of thumb says can cross at 2x550 but...Looks like another resonance or something around 1,8 to 3 KHz. Can even detect a slight rise on the impedance graph around that area. Not sure if it can be heard crossed steep near there but one could wonder about it. Do you need to cross it that low or could you go after this anomalie? Mainly wondering aloud I waven't worked with metal dome as a practice.
How about this one if you need to cross that low? http://www.madisound.com/cgi-bin/ind...6919&pid=2155. Looks much smoother but rolls off probably too much off axis around 8 KHz or so, but combined with a gentle single cap Xover and super tweeter might be the ticket.

Hi infinia thank for the reply


This is my second attempt with metal dome tweeters. I first tried an aluminum dome didn’t like it, maybe I screwed up, it was 10 years ago. I know a little bit more now. If I don’t like or can’t get it to work properly, I have two Seas 27TDFCs.

Im using the RS180 as midbass, so the crossover point will have to be in the 1.8k area.

My project is already underway; it can be anything more than a two way system

Oops OK you have them already, sorry I thought you were in planning stages. Still can use a second order HPF a little higher maybe at 2.5KHz as a backup plan for the tweeter. Woofer is metal as well, so uses a notch or a Cauer 3rd order.
