    replied to Fulcrum FA12AC and TS212 subs?
    Regarding the Brooklyn-Audio products:
    They are certainly a step up in quality. All Sander's products sound smooth and can be mixed&matched (they all have similar phase-response). They use high...

    Yes, I think all types. The response will differ per type LR/BW/BS, but it will have peaks and dips because of the delay in the high driver and the relatively large overlap in output of the drivers around...

    Okay... after some experiments with a passive x-over my conclusion is that you need at least 24 dB/oct slopes for a smooth response (on- and off-axis). With a lower slope (12dB/oct) you can only get a...

    replied to 60 Degree DIY Mid Hi
    I found that the bracing as defined by Peter Morris is sufficient. I used 15mm birch ply. But, if you want to add more, you could add a brace across the horn mouth and/or from side to side within the...

    replied to New DIY Mid High
    The BMS 2230 horn is too short / cut off frequency too high. You want to have the cut off frequency almost factor 2 lower than the x-over frequency. The RCF HF950 has a cut off of 400 Hz and is already...

    replied to mirroring S16's
    This is not possible on a digital snake: there is automagic addition of signals...

    You will have to patch (digitally):
    I assume that you daisy chain the S16s, so their inputs will be...

    4kHz is above the x-over frequency and the high driver is isolated from the box volume.
    The low pass on the low driver is not steep enough, so there is still interference at 4kHz, but I do not...

    The dsp in the M50Q has sufficient all-pass filters to flatten the phase of a 2nd order passive x-over. There will be even enough eq to flatten the amplitude response as well. So, you only need to make...

    I don't have a scale to weigh them, but the mic stand is quite stable. The weight is within the base, so it even helps to keep the stand on its feet.

    You don't want to see my measurements...

    Hardware (almost) done. As expected the filter needs some work :-)
