Details

CT Sounds engineered the Thermo 12” Car Subwoofer to meet the demands of the SPL crowd looking for unparalleled loudness. While the Thermo 12” shares a 1500-watt RMS power rating with the popular Meso 12”, it stands out by delivering exceptional peak loudness at targeted frequencies (SPL). In contrast, the Meso 12” is known for its impeccable bandwidth - you can play very low, very high, and everywhere in between, making it ideal for individuals seeking consistent loudness across all frequencies (SQL).

Quick Facts:
RMS Power: 1500 Watts
MAX Power: 3000 Watts
Voice Coil Configuration: Dual 2 Ohm
Push Terminal Size: 4 Gauge

Observing many customers running the Meso 12” outside our recommended box specifications (1.5 ft3) in pursuit of high SPL peaks, we recognized a crucial issue: as the box size increases, the SPL range narrows, potentially causing the subwoofer to unload. This realization spurred the development of the Thermo 12”, featuring an oversized motor assembly and a 10-inch quad-layered spider suspension, ensuring stability when chasing those SPL peaks. Moreover, the subwoofer features a mega foam surround seamlessly integrated with the 6% carbon fiber reinforced cone.

While the Meso 12” excels in delivering consistent loudness across all frequencies, the Thermo 12” focuses on achieving exceptional SPL peaks. Although the Thermo 12” sacrifices some bandwidth compared to the Meso 12”, it offers unmatched capability in reaching those peak loudness levels. If you're in pursuit of 150+ dB and aiming to make a bold statement with your sound system, the Thermo 12” stands as your ultimate choice.

*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.

Thermo 15

with the 12" I had now adding the 15" Thermo you can hear me coming it hits hard as hell. I also have two 10" subwoofers, but they aren't from CT Sounds. I'm thinking about getting two 10" Mesos but that was $550 more than I have to spend at the moment
