Midbass options?

[3.5Max6spd 10+ year member]

There are a few 4ohm 8" mid DIY options...

Morel Mw265(paper)

Morel Mw266(poly)

Vifa Mg22

Vifa premium PL22

Or here ya go, a cheap 'experimental' route, 4ohms, high Qts for IB, and 93db efficiency to try to mate to horns

What r the pros/cons of running an 8ohm driver instead of a 4ohm? I know that it will b less power going to a 8ohm than a 4ohm.

You are purchasing an entire speaker, not just an impedance. And the performance of the driver itself off of the power you have available, and not it's impedance, should be your deciding factor.

Wiggins told me a real 30-40wrms @ 8ohms would be good on the Extremis IB.

I actually hope it takes them that long...

Any reason why? //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

They would be done faster than that even if we made them in china...

There is an IF in there for a reason //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- but yea if we did and if the Chinese managed to keep QC good enough that we didn't have to toss out 1/3 of them... thn yes I would imagine a lower price point to get the larger order quantity required to make china economical...

Also that parsexpress mid is rated at 93dB/2.83V/m -- if you were to rate with 2.83V for our mid @ 2 ohms... that makes it about 100dB/2.83V/m //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif -- but yea thats kinda misleading...

Just thought I'd point out that little sensitivity trick that is often used //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I've heard some good things about Usher drivers...how about these?

http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=296-616

Also have been looking at the 8" Dayton Refs. Suggest some things from Madisound or Partsexpress, probably gonna run a 8ohm woofer.

Let it Burn

8955a has me curous as well, looks good..

 

[96MaxGLE 10+ year member]

Yea I had looked at those, too. I talked to ID, and he gave me some specs to look for.

Q : .3 - .5 (lower n the range the better)

FS: mid 30 - 60

Efficency: 88db (4ohm driver), 90 - 92db (8ohm driver)

he also said that a paper or poly cone would b my best choices for cone material

I'm thinking about ordering my drivers single for testing purposes first, and once I find one I really like order the 2nd one. Not sure what kind of amp I'm gonna run for my mids yet, but the guy at ID said if my horns r getting 25 x 2, I should at least give my mids 125 x 2.

[96MaxGLE 10+ year member]

Do you have any experience with these? I'm really looking for a 8" driver, but I have heard good things about these. What kinda power do these things need...I see the effincency is a little low @ 86db...
