    Chris,
    Those are very attractive. I would like to hear them. Good work.

      I made some pretty major changes to my Trials' crossovers. Mainly moved the woofer to mid crossover point up. That fixed a resonance issue the mids were having. If I drag them out to the next DIY I think most of you would like the way they sound now.

      The lowest possible F3 box alignment is not always the best alignment.

      Designing and building speaker projects are like playing with adult Lego Blocks for me.

        Craig,

        Were you able to close that dip I thought I heard around 250hz? Otherwise I thought the were terrific.

            'Tube Feedback' question?

            I don't understand...so what else is new.

              I guess it must have been a different Marty from Wisconsin that was trying to understand a tube amplifier feedback circuit on diyaudio. Sorry.

                No, I'm pretty sure there's only one Marty from Wisconsin.

                  And Rightly So! :D

                  But alas, it was not I. Some transient imposter I'm sure.

                    Well, in the spirit of other tweakers, I went ahead and took some detailed plots of the RS28A version of the mini, and re-optimized a crossover for it.

                    After modeling the plots in PCD, I whipped up a crossover, and took a pair of sweeps, 1m in room, 12th octave smoothing, 0 and 45 degrees.

                    Not bad for a first attempt.
