I am running a Dayton spa500 with a jvc arsenal 12" 600w rms in a 1.5 cubic foot enclosure. I was wondering is there anything I could do to make it louder or cleaner sounding,maybe dynamat inside or anything? What are some things you guys have done? Also what kind of settings should I keep it at like crossover and phase and freqency setings ... I'm really new at this. Thanks guys

    Mount it on spikes to decouple it from the floor. This will clean it up some.

    My HT room has a laminate floor which, in my experience, is bad about transmitting vibrations and basically becoming a large transducer. I have my sub placed on a heavy flagstone slab and it helps reduce that effect drastically.

    I added a good amount of polyfill to make up the extra .5 ft I really needed. I just can't have it too big. I'll give the corner a shot! Thanks. I bought these large lag bolts, do you think they will be suitable for use as spikes?

    Polyfill adds 10% cheapest place is at fabric stores .
    Decoupling may change the tone but it will decrease the bass , auraflex sells sub pads but before you spend a cent on a pad try setting it on some foam pads and see if it sounds better .
    I have never been a fan of spikes decoupling a sub would be removing the bass wave from the ground so=less bass .
    But in the case of wooden floors it would help especially w/mids .
    But the corner loading will increase the bass tons .
