    Bass horn coupling

    I've been trying to understand this for the longest time and I hope someone could help me out here. I have built some tapped horns around B&C's 18ds115 which behave great in large stacks (4+ bins), however when used in singles or doubles there is a quite significant saddle shaped dip in the...

    60 Degree DIY Mid Hi - AKA PM60

    That's sensitivity though, seeing the 464 has a higher SD and larger voice coil, and midrange will probably be limited by it's excursion won't the DCX354 bottom out way before the 464 when crossed as low? I guess that's why the recommended crossover frequencies for both drivers differ, since...

    Horn bass frequency range

    I second Rob here. Living in the EU, most dance systems have a two-band bass solution with subs covering frequencies up to 80-90Hz and "kick" bass bins covering the upper bass. The main reason for the upper cutoff frequency of kicks being < 250Hz is the amount of ~120Hz energy required...

    Port Holes on Horn Walls

    I'm definitely not an expert so please correct me if I'm mistaken but I have been building some synergies and most do indeed have reflex ports in the horn. This is different from mid injection ports as the location of injection ports are based the upper cutoff point of their passband. The reason...

    PMA - 60; New arrayable double 12 and horn.

    Looking good! Out of curiosity, which 12" drivers would you have gone for in an ideal situation? What about the FaitalPRO 12PR300 for example?

    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:

    Double 15” and Horn Drum Fill

    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...

    Double 15” and Horn Drum Fill

    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...
