It's somewhat misaligned, but your call as to whether it's off too much:

it'd be a one octave bass thumper. any way to "adjust" for the CSS?

CSS sells the woofer and 2 PRs for $200, which is a pretty good deal.

No more so than the Lab12. Not at a glance, it really 'wants' a lower tuned alignment down around 11 Hz based on Prof. Leach's math.

Here's what I get 'blowing up' a Prof. Leach alignment to the 'close enough' same net Vb, so import it into HR to fiddle with to see how it might can be adapted:

Hi nuconz,

When you look back at Hornresp listing in the first post, you'll see that Le is listed as 8mH. The nominal inductance for the LAB12 is 1.48mH. That means a series inductor has been added to smoothen the response. In practice that may not make much of a difference. The resistance of the inductor is added under Rg (e.g.: .1 Ohm for the supply cables, and .05 Ohm for every added mH of series inductor.)

Also, mwmkravchenko has build a nice, big FLH with the CSS TRIO12:

everyone, thanks for taking the time to look at the possible "fit" for the trio 12 sw. i'm running on a linux system and don't run the cool hr sw.

thanks for this oliver. i'm confused a bit though. the project initially identifies the driver as a CSS trio 8. but throughout the project there is reference to a 12" driver. and CSS doesn't include an 8" trio driver on their product list.

Hi nuconz,

You are correct, the TRIO12 FLH thread meanders a bit (ok, maybe a lot), but it's well worth the time spend reading through it. CSS used to make a TRIO-8, it's shame that they don't have it anymore, was a great little speaker.

Regards,
