[QUOTE="brandon_s0854, post: 7646977, member: 623673"] Yesterday I installed a new enclosure for my hdc3 10's. My old enclosure was built for my Grand Prix, which I no longer have. The box sounded great, but was extremely overbearing in the 35-45hz region; so much so that I had my subsonic filter on my 2200d turned way up just to even out the sound. Unfortunately, this also meant that anything below 35hz was pretty much non-existent. The biggest reason I rebuilt the box, though, was because it didn't fit in the back of my Edge very well. I figured I'd build a new box to gain more useable space in the Edge and try to alleviate some of the 35-45hz output, which in turn would allow me to turn down the subsonic and get that low bass back. The old box was 3 cu. ft. @ 35hz with the subs and port facing the rear and the port on the right side of both subs. The new box is 2.6 cu. ft. @ approx. 38hz. Again, both subs facing the rear, but with the port in the middle. Port area per square foot is almost identical. I figured the slightly smaller, higher tuned box would help alleviate the earlier mentioned peak in response. The new box seems to be slightly louder in the 40-60hz range, but has much less output below 40hz; I'm talking at least 10dB, probably more. Also, there seems to be less output in the 60-80hz range as well. I figured there would be slightly less output below 40hz; that's what I was going for. I didn't think there would be a huge amount less. And what's going on with the midbass? The last thing I expected was less midbass! Bass above 80hz seems to be unaffected. Any ideas what the problem is?! I need some suggestions. [/QUOTE]
