Electronic Bass Trap
Bag End is supposedly coming out with something called the E-Trap which is
an electronic bass trap. I've never heard of this. Has anyone else or anyone had any experience with them? It sounds intriguing and great if it works. -- Thanks, Ricky W. Hunt freendeed |

It looks like an interesting idea. It looks like it will probably be more expensive than an equally effective passive bass trap, but probably more compact as well. In a small room that could be a real plus. In a big room it is less likely to be. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Is is something like noise cancelling headphones, only for low frequencies? Hmm... yeah, I guess so. I never thought about it like that. Ken Kantor's company after NHT Pro (before his present one) had an instantantaneously steerable subwoofer that would change its radiation pattern based on frequency to aim the sound toward palces where reflections wouldn't be a problem. I thought that was pretty cool. How many individual drivers did it have? I have often stacked two or three subwoofers into a line array to get directionality and then moved them around to get the room peaks and troughs evened out as much as possible, when doing PA work. But it would seem to get truly accurate directional control, you'd need a whole lot of drivers. Or (heaven forbid) a bass horn. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Goggle ACTIVE BASS TRAP
I thought of this about a year ago as a cool new idea to get rich, unfortunatlry someone else thought of it before me. :-) Mark |

control, you'd need a whole lot of drivers. Or (heaven forbid) a bass horn. The new SPL BDeap subs get an amazing amount of direction control with just 2..with 4 it's very impressive..with no processing. John A. Chiara SOS Recording Studio Live Sound Inc.

I can't recall for sure but my impression is that it had two back-to-back and maybe a third one. Kind of worked like an MS microphone in reverse (or an ILS). Lotsa DSP That doesn't give you much control. With two drivers you can make a figure-8 with a single null plane, and you can steer it a little bit at different frequencies, but you really need a whole wacking load of drivers to give real directional control. It might be enough, though. That would be a fun thing to try. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
