There is no substitute for cubic inch or in this case surface area


After listening to quite a few speakers, my conclusion is that if you want large enveloping soundstage, you need a lot of drivers.  

I once had a speaker with two 12in. drivers and the soundstage is just floating in the air.  None of my other speakers could do that.

Currently I have a pair of Thiel CS2.4.  It is a very good speaker but with small drivers there is really limitation to what it can do in term of soundstage size.  I really miss that.

@larryi Wrote:

Truly large horns, with the right drivers deliver scale, impact, and authority at lower volume levels than any other kind of driver.

I agree!

Mike!

Check out a pair of Legacy Focus SEs. They feature 2@ 12 inch woofers. They are incredible. 

Discounting surround widths, cone depths, voice coil dust cover diameters, and any additional surface available from any ribbing in the cone itself:

6" dia. = 28.27 sq. in.

8"  "     = 50.27  "   "

10"  "    = 78.5   "   "

12"  "    = 113.1  "  "

18"  "    = 254.5  "  "

pi x radius squared for anything else....

I play with truncated cone surface areas.....

Mine work out to be about equal to about a 9" dia. in the diameter of a 6"... ;)

Voice coil suspension and travel is whatever I want to play with, keeping in mind the surround pistonic travel will require.  And not a lot of concern over tariff ruckus for the immediate future....

Mix 'n match to your pleasure, J

@dynamiclinearity Thank you for pointing out Q = 0.707 (1/√2) resulting in flattest freq. response. Do you happen to know how is it derived?
