You touched on the one sticking point between the two.

A large surround like Eclipse used on the Ti and what 'Bahn uses on something like the AWT15X will reduce Sd.

If you design the driver correctly, surround material shouldn't affect sound //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Maybe not so much in subwoofers.....but in a mid the material itself will affect midrange/top end response.

Just to clarify, it isn't always irrelevant.

But as Jack said; the main difference between the two is the difference in Sd.

That's my job to point out the one technical scenerio that makes your blanket statement incorrect! I want it back!

Sd=effective projected cone area //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
