I really enjoy my flat sub—Alto Mobile Falstaff 12"
Flat 10"?
I'd say Elemental Designs SQ10 or Exile Audio Flat 10 or Morel Elate 10 (had one and likes ported though)

Hope that helps,

Fixed;)
The flat cones are definitely secksy! I have a couple eD flat subs.

oups... flat as in ____ not small mounting depth. heh
My bad :D
You might want to ask Lambros, owner of ULTRA SUBS about flat subs.
He designed he old PPI flat cone subs for PPI all those years ago...

I've still got a pair of the PC10 flat pistons and I like 'em very much.
I don't like the SQ10s from eD. Mechanical power handling sucks. Bottomed out in .4 cu ft with 250 watts.

Hmmm...I didn't know that.

Im kind of wondering the same thing myself.
What are the trade offs between a flat vs. dished cone? Besides the obvious reduction in surface area.
What about cones with goofy things in the middle like the MB Quart RSH304?

That's not a "goofy thing", it's the magnet.
No, no. Not on the back of the basket. In the middle of the cone. Its the dust cap but its cylindrical and has its own rubber surround. Almost like two cones in one.
BTW, nice avatar.
GEAUX TIGERS!

quality_sound is correct sir, that is the magnet. Illusion and C-Mass made subs with the same or similar design.
I was just about to post that I saw similar designs from Illusion.
Whats up with that configuration?
First, I think we should clarify terminology:

There is no such thing as a flat cone. You can have a cone diaphgram, or a flat diaphragm, but not both. Cone, dome, flat: these adjectives describe the shape of the diaphragm.

The biggest problem with flat diaphragms for subwoofer use is that there aren't many who've been able to make one suitable for high output, and quite often it is simply a cone diaphragm with a flat diaphragm laid over top of it.

On the RSH304, the thing in the middle of the cone is the magnet system. It is inverted within the cone to save space in the rear (thus making it a shallower driver). If you look at the rear of the driver, you can clearly see that there is no magnetic system attached to the rear of the basket.

Right, poor choice of words.
Interesting, I wasnt aware of that, I thought I saw a magnet back there.

Oh for cryin' out loud. Let's just hop onto the semantics bus. Everyone knew what he was asking. Holy Christ on a cracker...

Well for starters, it probably would have been confusing to describe a flat subwoofer like this:

It uses a cone cone with a flat cone laid on top of the cone cone.

Thus I had to describe the semantical difference between the words in order to use them in a way that would convey their meaning (since that is the point of the thread).

Yes, everyone knew what he was asking, but I wanted to provide him with accurate information. You can reply to questions the way you want, and I will reply the way I want.
