*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.

beefy 12”s 🤯

Didn’t fit in my box which was a bit unfortunate and had to invert it. It had a bit of a burnt smell which scared me to death thinking the coil broke the first day but all round pretty good wiring to 1 ohm will be warm but I think inverting it is the best decision I made because it’ll never be hot

12’ strato hits hard!!🔥

I have 1 Strato 12 in a Ct1x12 sub box in my accord and it hits hard 🔥have a burnt smell at first but I guess it was just breaking in because it no longer gives that smell. Definitely has my car shaking! Now I’m for sure getting more Ct products 🙏🏾🔥

3 years later.

3 years later and my 12" Stratos are still shaking the ground and houses in the area lol. I paired my to 12s to a taramp smart bass 3k in a sealed enclosure and they still bring a smile to my face. The only not bad thing is when get a prefabricated box is you have to open up the hole cause these subs are not your normal size 12s. I am super happy with ct sounds.
