*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.

Single strato 12

I put this in my bmw to replace and alpine 12. This has way more punch and chest feel. Hits the lows really well probably borderline obnoxious to anyone next to me at a light but hey that's why we buy these we are bass heads I'm using a jl rd 1000/1 to power it and it sounds great plenty of head room for me personally I finally find my self turning it down from time to time

Strato 12s

Man these subs are absolutely beautiful! They are very solid and well built! Currently breaking them in but already sound amazing! They replaced the Tropo 12s I have had for
The last 3 years and the upgrade was instantly noticeable! I love this brand and being from the FortWorth Texas area I will never use another brand for my audio! Thanks for all you guys do at CT Sounds! #KeepSlappin!

Great SQL Subs!!

These subs are very responsive and sound great! I ordered two but need a better amp to push them. Currently have one 12 inch Strato on audiophile apmn-1500.
They don’t need a lot of space to sound good! Plan on getting custom box built for these as they are high quality builds and have beautiful baskets! I have the single sub inverted right now and get head turns like crazy. Just the one sub pounds hard outside of my suv even at low volumes.
Highly recommend!
