I'm going active eventually and was checking out some different mids. What do you guys think about this combo? I'm set on the tweeter so don't bother recommending anything different :).

BTW the Chargers are getting a new a-hole right now :D

Vifa Classic D75MX41 3” dome midrange

It's pretty flat from 900 Hz to 7 kHz.

I am thinking about getting a 7" woofer for the low end. I already have a 12" sub.

This is the tweet I'm getting.

Good midrange? Any other suggestions?

The reason I'm going with a 3-way setup is because of space issues. I want my mids and tweets in kickpanels and in an Integra anything over 3-4 inches would just take up too much space. So I'm putting the woofers in the doors and the mids/highs in kicks.

Could you put the prices on this items please? Thanks a lot!

It doesn't look like that mid is enclosed and its 8 ohm! Good for a passive but not active IMO. I suggest looking for other mids. The DLS IR 3" and Hybrid Legatia 3" are both excellent. Also Alpine uses a car audio friendy version of that tweeter in some of their Type X comp sets.

That IS the car friendly version :)

Can you give me a good source for those speakers?

I know it's 8 ohms, but if it sounds good I don't care.

The mids are $76.05 each and the tweets are $33.40 each.

Didnt see that it said integra. No need to be a *******.

How much power can those tweets take?

Big Dee
11-12-2006, 04:09 PM
Around 100 watts RMS, maybe more.

Any other 3-4 inch midrange suggestions?

Vifa XT25SC50-04 Ring Radiator tweeter

.

Very nice sounding tweeter. This is the same tweeter used in the polk srs. One thing to consider though, its not very loud. While it does sound very good, its not loud enough for many.

By car friendly I meant that they are traditional car audio tweeters, easy to mount, have a grill, etc...

Are you limited to Vifa? Have you looked at Dayton or Peerless?

Or Seas?

Or Scanspeak?

Not at all. The shop did several installs with the polk sr comps, and the tweets seemed to be lacking somewhat. Still sounded very good though. They are very laid back. Some people may like them, some may not. Great tweeters though, ide pick up a pair for my active setup if they were louder.

Its closer between these tweets than the hd3 is to the dd9500. Thats about as best I can put it. Not trying to steer anyone away from this nice set of tweets, I may end up running 2 pairs for my needs. Very smooth to the ears. I like them alot.

In all honesty, I can't disagree with you more.

They get loud, and are at times... a tiny bit harsh.

Wow.

So does the Polk Designed xover, and power ;).

You're comparing different things.

speaker impedance doesnt affect active crossovers because they cross the signal before the amps. Then the amp just drives that signal into whatever load is hooked to it.

No.

It was just coincidence that I picked 2 Vifa mids. I also found some Dayton and Scanspeak mids that look good. I've looked at everything at madisound and partsexpress, so yeah, Dayton, Peerless, Vifa, Seas, Morel, Aurasound, Hi-Vi, etc.

I am leaning towards some 2-3" dome mids now since they are tiny and still extend down below 1 kHz. I think having a 2" dome and a 1" dome right beside each other in a kick would look ******. Then caraudio ignorant people would be like "**** those little things put out all of that bass?" and I'd say "hell ya those are made by Bose" :D

:word:

Which is why I don't care if they are 8 ohms. As long as they don't need a lot of power it won't be a problem.

Changed my mind, again. No more domes, going with 4.5" mids.

This thread is basically me thinking out loud :) I figured imaging would be better if I had 200 Hz and above aimed at me as opposed to 1 kHz and above, plus I can't find a good crossover for that.

Here is the plan now.

Same tweet of course, but some Seas midranges and midbasses.

http://www.madisound.com/images/product/h1152.jpg
Seas H1152 4.5"

Nominal Impedance 8 Ohms
Recom. frequency range 45-5000 Hz
Short term max. power 200 W
Long term max. power 60 W
Sensitivity (1W/1m) 86 dB
Linear coil travel (p-p) 6.0 mm
Max. coil travel (p-p) 9.0 mm
Free air resonance 57 Hz
Price - $46.15 each

Sealed box of 1.5 liters (0.05cf) for f3 of 130Hz

For the midbass these look good, but so do about 20 other drivers, so this could easily change.

http://www.madisound.com/images/product/h1224.jpg
Seas H1224 7” aluminum cone woofer

Nominal Impedance 8 Ohms
Recom. frequency range 40-2500 Hz
Short term max. power 250 W
Long term max. Power 100 W
Sensitivity (1W/1m) 87 dB
Linear coil travel (p-p) 12.0 mm
Max. coil travel (p-p) 22.0 mm
Free air resonance 33 Hz
Price - $69 each

BTW I know they are 8 ohms, but I'll just get a powerful amp for them, should be fine.

The crossover points I was considering are:

Tweeter - > 3 kHz
midrange - bandpass 200 Hz - 3 kHz
midbass - bandpass 50 Hz - 200 Hz
