    The only thing that will bother me, when I get done is, I will never know what gave me the biggest improvement. Will it be going point to point? (eliminating the board), going external with the crossovers, or the MR caps w/Duelund resistors?

    Or maybe just maybe, there will be no improvement at all?? I doubt that will happen, but will it be a big or small improvement?

    I think the MR caps will provide you a pretty substantial upgrade. PTP in theory should not gain you too much...

    Man wiring that up was a tight fit! The molex connections are recessed into the Delrin, individual holes drilled, wiring soldered up to the delrin and then a bead of hot glue around to secure, extremely strong mount, IMO

    I have had the pleasure of seeing these almost completed in person. My hat goes off to Trey for the professionalism and build on these things. Trust me when I say that they are not just "slapped together". They look much better in person and these pics, while good, are not as impressive as when you are holding the entire modded crossover in your hands. I'm so glad he's doing the external crossovers for my Tyler Acoustic Linbrook Signature Series speakers!

    Every mod I have ever heard Trey do sounded much, much better than the stock counterpart.
