Hey guys. I finally blew my alpine type R 15 after 4 years. Had my alpine mrd m1005 running to it in a sealed enclosure. It was loud and got 141.4 db at a local comp I did just for fun to see how loud I could get. Time for a new 15 to replace it. I'm wondering if anyone knows a good 15" that compares to the type r or better that will run off that 1000 rms nicely. Many of the subs I like seem to be made for ported enclosures. I'm not against ported box but can't afford to have one built right now and I always liked the sound quality from my sealed. I want to go for a ported box in the near future but want a well built one with low port noise and tuned. Does anyone have suggestions for a sub that will run on a sealed enclosure for now nicely but even better in a ported later? I thought about a DD 2500, or American bass TNT or XFL, but it looks like neither do well in a sealed box. I been out of the car audio loop of whats good, so any help is appreciated.
