Agree and I have looked. The attractive thing about this Sub is the form factor. It's for a family room, using it with wall mounted GoldenEar Superstats. My Seismic 12 still performs, but is starting to have a mild buzz again. I am ok with sealed. I can compare form factors with the HSU. I am content with my JL in my HT room, I don't need another sub that costs that much
