Pls Comment on My MTMWW Design

[kestrel200]

I'm in the begining stages of designing my next set of speakers. They're an MTM ww 3 way probably using the following drivers:

Tweeter: SEAS 27TDFC or Scan Speak 2905
Mids: Vifa P13WH or Peerless 850108 (CSX)
Woofers: Peerless 850146 (CSX)

I'm also thinking about using a series crossover. What do you think?? Anyone out there use these drivers in a 3 way yet? If so what crossover did you use & how does it sound? The box would be a sealed desing of about 80 - 85 Liters with an internal sealed enclosure for the MIDs. Yes I know that's a pretty big encloser, my Datyon 8s are about that size. Anyway I would love any thoughts or advice any of you might have on this design. the only thing in concrete is my choice of woofers since I already bought four 850146s.

What no comments???? It's much too quiet tonight.

Hey this is not fair.. I like that idea so much but no money or time to build them i wish i could see them in action.. What drivers are you goiing to use.. ?

 

[kestrel200]

Probably the SEAS 27tDFC tweeters and the Peerless CSX drivers. Have you heard any of these?

What's your budget?

 

[jleaman]

NO im a focal Fan.. but im interested in your project.. ALOT..

 

[kestrel200]

Well I already have the woofers so I'v budgeted about $600 US for the remaining drivers and Crossover.

Jason are you aware that your link is not working? BTW I love the pic of the woman. who is she?

 

[jleaman]

That woman would be my Faience.. and the link ill fix right now.

One challenge will be dealing with the very low impedance the parallel mids and woofers will generate. Make sure you have an amp up to the task.

Good luck, and keep us posted.

Last i heard you had just broken up... now you are fianced... a new one or a reconciliation?

And it doesn't pass the iCab test... i get just enuff to know there is supposed to be something there.

Your right. I'm thinking about using a series crossover. Does anyone have experience with these?

BTW what's Icab???

Have you given any thought to making the MTM section dipole? Would save a bit of money from the missing cabinet.

We didnt break up.. we were having problems. and stuff.. This is year 3 that we have been going out..

Now my Fiance

I think the dipole suggestion is a good one...not to save cost, but for SQ. Heck, I'd go dipole with the woofs! Maybe a little higher definition mids.

Series xo's can work well, but a pain to tweak. SW optimizers, at least LspCAD, won't work with them.

4-way dipoles

I'm just glad it IS his fiance or whatever. I really hated the idea of a beautiful woman named Jason.

I'v thought about this but from what I've read and understand the crossover gets even more complicated with a dipole. What higher definition mids are there that are still as easy to work with..nice smooth roll offs?

I've looked at your website many times and drooled over your speakers. they must sound awesome.

Scan-Speak 8531, if you can afford those.

PE Link

You can also go for a standard TM design like this one.
