This is more of an edit to a previous review but it wouldn't let me edit. FINALLY got around to getting about 3/4 finished with the infinite baffle setup in my Prelude and even with all the gaps the still need sealed.....it bangs!
Bought two of these 18” subs to give them a try. I’ve been very dedicated for over twenty years to other brands. I thought I would buy some middle of the road subs from soar and see what happens. Well let me tell ya I’m shocked. Built a 4th order band pass box and holy crap. I’m running one Rockford 1200.1 at 1 ohm per sub. Box is tuned at (rear 29 Hz) (Front at 50 Hz) needless to say they slam hard and have been for months now. I will have to upgrade my alternator and add batteries but considering I’m still building it out and have a lot left it does hit hard. Metered at 153db.
I purchased two of these 18s DVC4 for home theater Duty. Each speaker was wired at 8 ohms and then brought together to be 4 ohms ran by a 500 watt plate amp. Better output and far cheaper than purchasing a subwoofer from your local store
