| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build @hsbrock , I used Bassbox Pro by Harris Technologies. I have a couple of other progams but they are no longer available. | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build @hsbrock , the modeled response that I described up-thead checks out. It assumes 3 dB from boundary reinforcement at 40 Hz, and 6 dB from boundary reinforcement at 20 Hz, and a lowpass filter frequency no higher than 80 Hz. It also assumes the T... | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build @hsbrock , I want to double-check something. It might take me a couple of days. Duke | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build @hsbrock I didn't use that 27 Hz figure; I just used the T/S parameters and a modelling program and estimated the boundary reinforcement from placement in or near a corner. I don't claim my suggestion is perfect, but it should be "in the ballpa... | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build Thanks for posting the T/S parameters, @hsbrock . You might try 7 cubic feet net internal volume tuned to about 24 Hz. This plus some boundary reinforcement should get you down to 21 Hz ballpark in-room. | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build @hsbrock , do you have the other T/S parameters? Qes, Qms, and Vas at a minimum? Imo 54 Hz is an unusually high free-air resonance for a 15" home audio subwoofer. Is this a car audio subwoofer? Or a prosound driver? | |
| Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build "I've got a driver with free air Fs at 54 1w/1m, but free air response remains fairly even down to 27Hz above 95dB" This sounds unusual to me. What woofer is this? | |
| Interesting Read From a Recording Engineer about EQ IF you decide to use equalization, DO NOT equalize the in-room response of the left and right channels independently. You want the first-arrival sound to be identical from both channels for a variety of reasons, including image stability. Apply th... | |
| Your experience of moving to two subs According to acoustics and psychoacoustics researcher Earl Geddes, the in-room bass smoothness increases in proportion to the number of independent bass sources. So two subs can theoretically be twice as smooth in-room as one sub; four subs can th... | |
