Joe X Posted July 3, 2015 Report Share Posted July 3, 2015 Hello fellow bassheads. I am currently running into a heating problem. I started to notice my subwoofer gets warm/hot to touch when playing full tilt for a while (20-30 minutes). I do not smell any electrical burn (burnt coils). Below is a screen shot of torres and what my box size and the tuning frequency. My subwoofer is an Incriminator Audio Lethal Injection D2 10". My amp is a Sundown Audio SAE 1000.1D wired to 1 ohm. Incriminator Audio recommends a box size .9 cubes - 1.5 cubes, 12 - 25 Inches of Port, 28-35 Hz (Average: 1.25 cubes, 18 inches, 28-35 Hz). Is my enclosure too big for the amount of power I am feeding the amp? Or should I have gotten the additional spider and optional 4-layer flat wound coil? Thanks. Where is your subsonic/infrasonic filter set at? This is usually used to limit excursion (which doesn't seem to be your problem anyways) but it can also prevent inaudibly low frequencies to be amplified which may help cool both the sub and the amp.

This is usually used to limit excursion (which doesn't seem to be your problem anyways) but it can also prevent inaudibly low frequencies to be amplified which may help cool both the sub and the amp. I set my subsonic filter at 22Hz. My box is also tuned higher than I though I was tuned to. It's tuned to around 37Hz instead of 32Hz.

reedal Posted July 3, 2015 Report Share Posted July 3, 2015 You want your subsonic set 1/2 octave below the actual tuning frequency of the enclosure. So if it's currently tuned to 37hz, then 37/2 = 18.5 /2 = 9.25 37 - 9.25 = 27.75 Set subsonic to 28hz SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...

But I didn't realize until now that my enclosure's tuning frequency was higher than expected. I'll be able to correct it later today or tomorrow down to 32Hz. Then I'll set the subsonic filter to 24Hz.
