*Flat response curve (SQ) is geared towards people looking for responsiveness. This style box is loud on all frequencies, generates little impedance loss, and can utilize an amplifier rated at the same RMS as the subwoofer.
*Boomer response curve (SPL) is geared towards people looking for maximum loudness. This style box will be louder than the flat response curve at some frequencies, has a high impedance rise, and can utilize an amplifier rated at a slightly higher RMS than the subwoofer.
*Enclosure recommendations do not account for subwoofer, bracing, and port displacement.

I bought this to toss in my daily Focus ST to have a little more thump. I found a sub box that fit their recommended specs for the sub, and it sounds great. I am running it with a CT 1000.1 amp, and couldn’t ask for much more out of a single 10. I have owned plenty of other brands over the years, and I’m very impressed with this sub, especially for the price.
They were great until I put upwards of 1800 watts and blew one up
Product Sounds great and you can’t beat the quality and performance at the price. Looking forward to my next purchase.
I am really amazed at how these subs sound I wish now I'd ha ha just went with the strato 12s maybe CT sounds will sponsor me one day
