Nope! This sub lives right up to their reputation. That's why I picked it, and I don't regret it in the slightest. I listen to a wide variety of music from Dance, Trance, Pop, Rock, Classic Rock, Opera, Classical, and the occasional Pipe organ medley. This sub always delivers crisp clean bottom end! Tight and punchy when it needs to be, and then smooth and robust instantly. I have this attached to an Alpine amp and it's a great combo! I was going to do a JBL amp but I'm glad I went with the Alpine! Great job Boston Acoustics!

I bought this sub from Sonic about 8 months ago and have it in a 0.75 cubic foot sealed box powered by the sub channel on an Alpine PDX-5(300W RMS). It is very clean and tight sounding, and plenty loud for my small hatchback car. I would recommend this sub to anyone in the market for good sound quality on a reasonable price.

Very strong woofers I can't complain at all

Very strong and good amp

Again great speaker. Pricing was very competitive. I have this connected to a Alpine mono-amp with a closed box of .72 cu ft. The bass is tight and not a slow whump whump whump. When a kick drum is struck it sounds like a good and tight. I have this installed in my BMW X3 and anything more than this is just over kill. I only wish the box I bought with it had a grill.

i would recommend this sub to anyone who wants bass that is clean and clear but louder then the guy down the streets. i own one of these subs now and i am going to buy one more! i have had this sub in sealed and ported boxes and it sounds amazing in both!
