Review: 👏 kudos alpine, you didnt disappoint 👏 - Ive never liked shallow mount subs but alpine got it right with the type s. NOT the loudest but with the limited space this thing gets me nice deep bass with a small underseat sealed box. The price is awesome too for a quality product.
Review: Awesome subwoofer for a decent price with good sound quality - Good punch and sound quality without breaking the bank. It only got better after it broke in. Powered by JL Audio JD500 amp, 600 watts@2 ohms in a 1.7 cu.ft box retuned around 33Hz. Just at RMS power for now. Any of negative reviews that said it blew up right away apparently didn't know that both speakers and subwoofers have a break in period but I digress. The only negative is I should of bought 2 and run a pair for even more thump.
