    This sub bumps really good. I put a 700w amp and handles it perfect. I would highly recommend.

    Sounded really good in a ported box until she blew. I had it hooked up to a Hifonics Brutus 1500 1 Channel so it cant take that much power. Recommend maybe 1200 watts and under unless you have two woofers.

    For 30 bucks it's an outstanding value. Sounds very good in 1 cubic feet closed box. Don't give it more than 250W RMS and it will last a long time.

    Subwoofer sounds really good. I got it on sale for $30 so for me was a great deal for a really good subwoofer. Its not the best i have ever heard but it is a lot cheaper than the best and like all jbl speakers it sounds really good

    These things have some power. I mounted them under the recliners in my home theater so that they would make the entire recliner shake when I’m watching a movie. I probably should’ve just used a couple of exciters instead, but it was a fun project and it works well. I had to buy a separate amp for them, but it was worth it.

    Bought this speaker on sale for $30. Had it for almost two years now and results have been solid. For $30 it’s good value for a budget setup.
