Well, the TRXB's have been "modified" over time by someone else and the T35's have been removed. So no, I was just using them for bass duty. The SP-12's, I know don't have ultimate extension but I'm really surprised at the HF response - seems a lot higher than 10k to me. I think the specs say they go 15k, but that may be optimistic. Over time I will likely add a tweeter for the upper 5k or so. Right now I've added a Dayton 15" IB sub woofer powered by a seperate amp. What I did was a first order low pass at 30hz, figuring that based on the OB design, and the response of the IB speaker, I'm flat up to about 100 or 140hz, and down to 30hz (since if a first order rolls off at 6db per octave, it also rolls on at 6db per octave). I'd appreciate any comments/feedback on ways to optimize.

Steve, I am building the crossovers for the Hawthorne Audio OB 15 Coaxials, so I'm not an un-biased source for info. I do own both the coaxials and the Augies bass drivers. You can read the review on TNT of the Coaxials here> http://www.tnt-audio.com/casse/ha_si_part1_e.html As for the Augie bass drivers, they were designed for use on OB as a bass driver and perform well at it. Flat to around 30 Hz on a modest baffle. Dave
