So what's the advantage of copper clad aluminum over copper? Weight, heat dissipation, all of the above?

No idea I never asked. Just ordered what he wanted.
I'll ask him next time we chat.

One has a copper voice coil, and the other has a copper clap aluminum voice coil.

Bob wanted a sample of each. That must have been the change in the Sunfire drivers as well.
So far, it looks like we will be using the 12 ohm CCA version.
They are both 4", the exact same size as the Sunfire drivers.


I would love to buy that 10 ohm if you go with the 12 ohm and still maybe get it and even a few 12 ohm one's :-k

Keep in touch after you know what way your going and when you get a shipment and some extra's you could let a few go from.

Leaning toward the 12 ohm sounds like the way to go in those towers to me :D \:D/ \:D/ \:D/

Re: The NEW 2010 "ALS" Concept - Design - Product

I thought you guys were going with a bigger driver design like 5.5"? Are all of those 4s really going to be able to play down in the 23hz range?

My understanding of how a cone driver works is that the size has nothing to do with how low it can go.

The problem with a single 4" driver (it seems to me) would be that even at 23 Hz it won't be moving enough air to "feel" the bass.

Given enough drivers that problem should go away

I listened to some Anthony Gallo towers with many (I don't remember how many but many !) 4" drivers & they put out excellent bass.

Re: The NEW 2010 "ALS" Concept - Design - Product

Doing a little mathamcation.... The cone area of 22 4" drivers, is equal to a single 13.25" woofer. For those at CarverFest this last year, the AL-VIs each had a 12" woofer, and those were PLENTY of bass.
I think everyone will be pleasantly surprised at the amount of bass these speakersmwill produce.

Re: The NEW 2010 "ALS" Concept - Design - Product

Hmmm, I get 18.761663039293718218262520454178 inch woofer. Remember Area = πd²/4 → 22π4²/4= πx²/4 or x² = 22×4×4. So, we're looking at an 18¾" woofer on those puppies.
It should sound like it isn't there!

Re: The NEW 2010 "ALS" Concept - Design - Product

BillD, I can't believe I'm questioning your data but somehow I think the area of a circle is Pi x R squared.

I don't even know how to get the right symbols up there but I think the radius squared times pi = area.

A 4" square is 16 square inches in area & a 4" circle will fit inside that square losing the corners areas.

Just my thoughts.

Still 22 4" woofers adds up to a considerable area moving air.

P.S. just caught the /4 part.

I knew I shouldn't question you !!!

Well, DUH, Frankie. Sure the area of a circle is πr², where r is the radius. The the radius is half the diameter or d/2. If you square that, you get d²/4

Re: The NEW 2010 "ALS" Concept - Design - Product

(r*r)*pi

(2*2)*3.14=12.56 sq. Inches per driver

12.56*22=276.32 total sq. inches per channel

now we reverse to get what size a single driver would be.

276.32/3.14=88/sqrt=9.38r*2= A 18.76" dia. Woofer

So, it will be like having (2) 18" subs in the room... Plenty of bass :lol:

Plenty of bass


You need cabinet volume to go with all those tiny drivers to get plenty of bass. Just saying.
Political Correctness...defined

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.
