The W3's are only rated for 250 watts rms. The 15's might be 300w rms, but I'm not sure. They can take more, but they'll do just fine with that power. I would never use anything less than 3/4" material to build any sub enclosures (if possible).Originally posted by pioneer

if i get the 15...what size of mdf to use...3/4" ?
