| speakers for small room "The room is 13’ x 11’ with 3 walls, the other side opening up to the rest of the house." If I understand correctly, one side of your room is effectively a large opening into the rest of your house. If this is the case, then in the bass region yo... | |
| SPL Surprise! 24 dB of difference under the conditions described seems reasonable to me. I’m not going to make a comprehensive analysis of all the factors that may be in play, and will be making some simplifying assumptions, but I think this covers the dominan... | |

| Flat frequency response Back when I was an avid amateur speaker builder, I borrowed some test equipment from a technician so I could fine-tune a crossover design, my target being the "holy grail" of flat frequency response. As I got closer and closer to "flat", the sound... | |
| The mistake armchair speaker snobs make too often Imo loudspeaker design is a competition of ideas, a vital part of which is the implementation of those ideas. Given that most companies have finite resources to invest in product development, it only makes sense to develop and perhaps manufacture... | |
| 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... | |
