Acoustic Energy Aegis Ones - T&S data?

[Gary Lightfoot]

Hi,

As a 1st project to help get me into the world of building speakers, I thought it might be easier to use the existing drivers, crossover and port from some speakers I already have, so that I don't throw away too much money till I know a bit more about the subject.

Anyway, I need to know the Thiele and Small data for the mid bass driver from the AE Aegis Ones so I can see how it works in WinISD with the new enclosure I've made. I've tried speaking with Acoustic Energy, but they were less than helpfull, so I wondered if anyone here could help maybe.

Failing that, I was thinking of replacing the driver with a Monacor Sph 135 ad, as the T/S parameters are available and I can use the info in WinISD to help with the box size and vents. Not sure how it'll work with the Vifa tweeter and existing 2.8khz crossover from the Aegis speakers though.

I've built the first box to mimic another speaker (it's not a normal rectangular box btw), but have since realsied the internal volume is greater than the Aegis box, hence the need to know the speakers parameters. I could just reduce the internal volume with bracing so that it matches the Aegis volume (9.8lts without drivers or crossover), so then the port size and length should be the same (shouldn't it?)

Any comments welcome.

TIA

Gary.
