maintrain, I like that finish, unique and different. Yes, at AE, you can get the two 18" PR-2100 for under $250. I can say that from running the TC 3K sub sealed and then in the 8cf PR box tuned to 15.5hz in the same location, it does quite a bit better in the PR box. Besides the extra SPL down low, it has a flatter frequency response. In the sealed box, it had a big rolloff after about 60hz. I realize that this is a high inductance driver, but why the dip in the sealed box and not in the PR box? Also, I know this driver takes well over 2,000 watts sealed to drive it close to its xmax but a PR box being more efficient, I wonder how much power it will take, 1,500 watts?
