*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.

Tropo 8"

These little tropo's hit hard. Running four on a Audio Control LC1500.1 and they can take more. Box tuned to 38 hz....exactly .48cf per driver after all displacements. My next build will be 3 to maximize the Airpsace to .60cf per driver tuned to 36 hertz. Great product. Gonna try the Strato 8" next.

Application: 2010 Silverado Crew Cab

Originally ordered a single Tropo 10" to replace a tired Kicker 10" in a rear underseat enclosure; unfortunately, the Tropo 10" was too big for my sealed truck box. After some research, I ended up ordering a full underseat dual 8" ported enclosure (1.45 cubic foot volume) and two Tropo 8"s - at 0.7 cubic feet/per, they were a solid match for SPL curve, playing primarily hip hop music. Currently breaking them in on a Skar RP1200.1D @ 1 ohm with a max of 50% gain; SSF set @ 30 hz and LPF @ 80hz. Wow! These bad boys SLAM for some 8s, especially for the value you get em at. Solid kicks without any distortion and they surprised me and my installer on how low low they can get. I may eventually upgrade to the Meso 8"s, but some hip hop baselines literally make it hard to breathe in cab and they're not even pushed past 50% gain yet. Very excited to feel their performance once they're broken in. With the proper box volume, RMS, and tuning: 10/10 recommended, especially underseat in a truck where air space is limited.

Little Bangers!

I put four of these in my 2021 Nissan Titan. I’ve been running them for about two months now, with a RF T1000-1 bdcp pushing them. The box has two side ports tuned to 38Hz, and they have 1.8cuf of air space. I’m not flexing my windshield, but these little suckers bang like crazy! I listen to a lot of EDM, and metal, and the sound is clear. I did lose a little kick drum tightness by going ported, but I’m still happy with the results I’m getting. If you’re tight on space, and you don’t want your wallet to cry when buying subs, you’ll be more than pleasantly surprised with all you’ll get in this small, affordable package.
