    I'm going through the same issues right along with you, Robert.

    So far I've tried the D45(pristine and newer model), a 1U QSC unit, and two UREI 6215. I've managed to get one UREI 6215 working out...

    You have a good starting point and it may be spot on. The manual shows that it starts rolling off ~45hz and the slope is ~10 dB.
    You will want to avoid boosting the signal until you have a decent...

    The BX63A sounded very good to me. This could be due to the passive only crossover components in the HF circuit. There was no detectable noise.

    On a budget, I would use a mini dsp to replicate the...

    Hi All. I have a few updates and questions.

    Rob's post has me intrigued with the E145 as a potential midbass driver. They can easily run down to 80Hz which is a much better crossover point for...

    I think Barry has nailed it.
    I've looked at several of them and didn't find anything quite like it that's currently available. Everything I've found has higher Fs.

    To show the difference, if you opt for brand new cone kits this is the latest price:

    C8R2235 $214.00
    C8R2245H $276.00

    Otherwise I've not seen used, good cond. units vary much.

    That's not bad at all. I think I paid ~$150 each for the 2397/throat.

    I'm doing this with the 2397 incorporated.

    You have enough parts to trade off in favor of what you would need for drivers. ...
