    Plate amps ?

    I've used the minDSP pwr-ice250 on a couple of different DIYs. One is currently mounted in the back of a box with a B&C 15cxn88 coax in it. I've also used them to drive PM60's indoors, when I didn't want any amp fan noise. (Had to make a funky rack mount panel for that.) On the PM90, i also...

    60 Degree DIY Mid Hi - AKA PM60

    Hi Jason, yep, three 1" CDs in a line, and two 6.5" mid cones on the center horn. I'm sure it will get louder, but I don't see how the multiple drivers can sound as clean as a single BMS coax/horn.

    12 low/mid drivers

    I'm using a RCF MB12N405 with the same 4594HE and horns that are in the PM 90/60. Same 650Hz crossover point too.. I always use it with a sub, 100Hz cross, and built the box to that spec. So i don't know how well it would tune lower, but I think getting to 80Hz should be very easy. It sounds...

    60 Degree DIY Mid Hi - AKA PM60

    Hi Peter, you beat me to it...saw the new Martin Longbow in LSI last evening and said, "hmmm, wonder where they got that idea?" ;)

    60 Degree DIY Mid Hi - AKA PM60

    Looks great Ivan, enjoy! @ Peter, yep, take Hennessy as a compliment indeed They clearly spotted your component selection / build. I've seen a few others (myself included) build off your driver selection groundwork. And I've seen at least one other similar design, that was willing to have...

    Dynamic speaker processing

    Yep, reflects my thinking too. I don't think any special processing, in terms of sliding crossover points, or tone control contours vs SPL, or etc, is being done with any of the common self-powered boxes. Maybe not any boxes period. Just plain ole limiting is all I've encountered, ...and...

    New DIY Mid High (90deg) - AKA PM90

    Hi Ti, Very nice work. The q-sys looks very capable. How many taps, at what sample rates, can it handle? One trick I've learned for aligning subs, when using linear-phase crossovers, is to find the sub's delay with everything in play other than the FIR filter. This usually gives a...

    B&C 15CXN88 build

    Hey Bennet, thought I'd try to kinda morph off the SM-80....but using a 15" and venting it. I see you guys recommend a 1.2kHz crossover at 12dB/oct or greater....... Do you think I could move crossover any lower safely , given I'm using at least 48 dB, even 96 dB/oct ? I won't hold you to it :)...

    60 Degree DIY Mid Hi - AKA PM60

    Huw, I had not responded because my EQ's are FIR files, and are no doubt too large to fit into the X8's available tap count. But I got to thinking...if you are using either rephase or FirDesigner, I could send the project file and you could resize accordingly. Let me know if that would help...

    X32 Rack as dedicated monitor mixer: maximum number of stereo feeds

    I haven't tried to verify 8 pairs of linked buses by checking final outputs, but the link indicators appear to say you can link all 16 buses into 8 pairs. Is there a limitation of 4 pair, plus LR, that the link indicators overlook?

    X32 Rack as dedicated monitor mixer: maximum number of stereo feeds

    Yes....just tried this...works! Set Monitor Source to Aux 7/8. Set Aux 7/8 Source on Home-Config tab to Mix Buss 15/16 (Aux 7/8 source is normally USB L/R)
