Dayton 15" ulitmax 4cuft sealed sub - not performing
So in the last 2 days I built a Subwoofer using the Dayton Ultimax 15" driver and Crown 1000w amp in a 4cu ft(~) sealed cabinet but it sounds rather awful to my ears. The sealed cabinet is well braced and pretty solid but I only used a thin amount of polyfill as I didn't have much on me at the time. Perhaps that's the problem or maybe I just don't like the way sealed subwoofers sound in my room. The sound is kind of thumpy and doesn't sound natural to my ears. It's also very directional, I can hear the bass coming from the cabinet even with crossover at 80hz, which is distracting. My pb-2000 didn't have that problem so much and sounded much more natural. I'm going to try vented but just wondered if there was anything obvious I was doing wrong, perhaps it's the polyfill. Any suggestions
