I do a lot of listening these days in front of my main PC, where an "old" Logitech X-530 multimedia system provides the audio. This is a fairly cheap 5.1 system (list price was $80) when purchased. I'm able to correct most of the sonic transgressions of the satellites with a bit of EQ. The woofer module is another story. Results of a few measurements confirm that it is a 100 Hz "boom box", basically consisting of a high-Q 4 ohm driver with a 58.5 Hz Fs jammed into a small box that results in a sealed Fb of 84 Hz. On top of this, the box is vented @70 Hz or thereabouts. Stuffing the box with polyester fiberfill, sealing the vent and then trying to fix the response with EQ has helped a bit, but the amount of correction that's required is pretty large (up to 12.5dB @100 Hz), the bass is still not quite there yet, and the sound card starts gain-riding the output if I push any of the sliders for bass frequencies above the 0dB point, so that limits the amount of correction at hand even further.
My idea is basically to toss the boom-box and replace it with a decent woofer module that can actually due 40 Hz without having to have a bit of smiley-EQ added. Power at hand is supposed to be 25W, but I'm guessing it's more like 12W, but because the new box is going to be corner-loaded, I doubt that I'd need anywhere near that.
So, I've investigated a number of different options (including one that puts the DC165 into an offset TL capable of doing 30 Hz), but then reminded myself that this is a WOOFER module and it needs to have a pretty decent (i.e. smooth) response up to 200~300 Hz as well. I'd also like a smooth rolloff below Fb, to take advantage of the "room gain" my small bedroom provides.
So I've done full circle and decided that perhaps going with a simple sealed alignment would be best for this particular need. I'm on the lookout now for any relatively inexpensive 4 ohm drivers that can hit an Fb/F3 of ~40 Hz in a small (~1 cu.ft. or less) box. Any suggestions? So far I've only found one or two car audio 8" drivers that can do the job, like the NVX VSW82V2, which can do what I want in a 30 liter cabinet. It is $70 though, so I'm looking for other options....
