Using other Crossovers for my components?
 

I have an MB Quart 6.5" Component set up (.75" tweeters). The Model is a european one that I assume is entry level even though it was bought at Future shop.
The model number is ESA 216. When ever I do a search on them it all comes up in Russian.
I got this set up from a guy for next to nothing and was used one week. Problem is he only had one crossover.

Can I use another pair of crossover's from another component system?
And if so how far could I stray?

Here is some numbers I got from the russian sites that had these:
50-100 W
42-32000
90/2,5
12db

What suggestions do you have so i can use these?

I should tell you that I have a Panasonic Deck that I'm going to run these off of. Its the 9701 model. It does 70x4 peak power. I believe 31 rmsx4.
I'm not going to be using a seperate amp on these.

MB Quart was bought out by MaxxSonics. That's why the have NO customer service and also why they're on sale cheap.

I have the RCE-216, maybe a higher model than you have, but i think they use the same crossover for different models.
The crossover frequency is 4.2k, so you can biuld your own or find one similar.
The good thing about the MB quart crossover is that it is bi-ampable and it has a lightbulb to bleed off excess power to your tweeter, so you don't melt them.

Thanks for the info tom.f.1. Really appreciate that. I looked at the crossover pics on the net between your speakers and my speakers and they are different to look at but close in specs.

How important are the specs? for instance my crossover is good for 42-32000... other crossovers from comparable speakers may read quite a different range.

I just dont want to go cheating my speakers out of good sound, or wrecking them for that matter. As you can see I'm a newb.

try to post the picture of the crossover and make sure all the letters on it is readable, by looking at the circuit i might be able to figure out what order and frequency the crossover is at. and u can just get parts from DIY speaker shops like madisound or partsexpress online and build it yourself

LOL... ok man. I would appreciate that. Maybe it's not as complicated as I think.
I took a pic and as you can see its not that clear.

The Yellow cylindrical piece says...
"Sounder"
MET 100VDC
4.7(symbol looks like a backwards u) 15%


The Black Cylindrical piece says:
10(backwards u symbol) F 35VAC

Then theres a white rectangular box there:
5W3R3J

Then the coils of copper wire you see there.

Here is a tutorial including a value calculator to build your own crossover.
I'd go with Second Order (12db/octave) Two-Way Crossover Linkwitz-Riley

You can biuld it on a standard 6 position dual terminal block attaching coils and caps to one side and speaker leads to the other. And, because the outputs are 180, you may have to reverse polarity on woofer or tweeter. On factory crossovers, the reversal is done for you, but now you have to match what they did. And that really screws up systems which have time alignmet.. Trial and error, tweek and tune.

Good luck,

Tom

Have you tried rolling into your local FS install bay to see if they might have a spare matching crossover lying around?

If not - go see Shaughn at Visions in Red Deer. He's the only guy in that town I would let go near my stuff. :thumbsup: He'll come up with a solution.

Tried him and he sugested the same thing as the previous posters. He didn't have any crossovers kickin around that would work.
I will look into making one.
Thanks for the contact!

as posted I would duplicate a pair of crossovers... parts express has etched 12db and 18db 2way crossover boards and the components you will need....

obviously you can get the values/tolerences needed for the caps and resistors right off the OEM crossover but you will need to remove the coils and measure their inductance... some multimeters have this feature...
