    Double 10 and Horn

    Hi Chris, May I ask what it is you don't like about the XT? When I first tested it I wasn't very pleased myself, I found it to sound overly 'shouty'/honky at certain frequencies, even at low volumes. However, this soon proved to be caused by irregularities in my phase response. After clearing...

    Double 15” and Horn Drum Fill

    Did a sound check of the top cabinet stacked on top of one of our bass horns today. Really happy with the overall sound. If anyone's curious here's a video recording I made:

    Tried changing it after registration but didn't find the option, probably should contact a moderator to get it sorted. Thanks for the advice about the half space measurement. I'll try to get some done tomorrow if the weather's good. Today I got distracted by listening to tracks from my...

    Double 15” and Horn Drum Fill

    Finally had a chance to do some decent measurements outside (even though it was a bit windy). Measurements were performed using a UMIK1 taped to a broomstick on a ladder, speaker facing upwards. The mic was placed at about 1m right between the upper woofer and horn) Pretty happy with the result...

    Thanks for the feedback Max. I use either Armonia (Powersoft) or my trusty XTA 4-series processor (IIR, they can do FIR but only very limited taps) depending on the system so I won't be doing any aggressive FIR filtering. However there isn't any abnormalities in the response which require any...

    Double 15” and Horn Drum Fill

    Hi Frank, The first prototype I built was with the BMS 2236 horn (I only redid the front baffle when I went with the DCX). I still have a BMS 4592 + horn and passive xo laying about if you're interested. I did like the sound but as I was planning to build 4 cabinets the B&C + XT1464 was just...

    Double 15” and Horn Drum Fill

    So I went ahead and ordered myself 8 PD.158 woofers and oh my do they sound lovely. The respone and clarity in the midrange is really good for a 15, and they need little to no EQ to match the DCX (only some taming around 300-350Hz). The lower end of their band (90-120Hz) sounds clean and punchy...

    Double 15” and Horn Drum Fill

    So I decided to go for B&C DCX464 drivers instead of the BMS because when building 4+ of these the difference in price started to become substantial. Today I did some tests in my prototype cabinet. Cabinet volume 260L including drivers, basic wadding applied but it needs more; reflex tubes...

    Double 15” and Horn Drum Fill

    Time for a quick follow up. I recently built a cabinet to try out this setup with some pretty good results. The BMS horn loads low enough and both on- and off axis response were good throughout the xo region (crossed at 600Hz). I compared this to a cabinet with 10" drivers and a dedicated bass...

    New DIY Mid High (90deg) - AKA PM90

    The Umik1 is less than 100€ where I live and it is a real pleasure to use, it is also automatically detected and configured by REW and comes with it's unique calibration file. No drivers or setup needed and works with any operating system. No doubt there are higher quality microphones if you...

    Double 10 and Horn

    HI Peter, Thank you for your explanation. The relation between mouth size and directivity does explain a lot. I've noticed something similar when slot loading woofers, which seems to push the narrowing in directivity up higher in frequency but seems to be limited by the bandpass effect it...

    Double 10 and Horn

    Quick question that I can't seem to find a good answer to. When talking about center to center spacing it appears that the measurement is usually done from the center of the woofer to the center of the mouth of the horn. Does that mean that this is where the acoustic center is supposed to have...

    Double 15” and Horn Drum Fill

    Thank you for sharing this Peter. I actually have been looking at ways to cross an efficient 12" with my BMS 4592 over some 15" kickbins; but reading this thread I'm wondering whether it wouldn't be an option to just take the more straightforward route and just use double 15's, ditching the...
