THERMO-15 // 1500 Watts RMS 15 Inch SPL Car Subwoofer
CT Sounds engineered the Thermo 15” Car Subwoofer to meet the demands of the SPL crowd looking for unparalleled loudness. While the Thermo 15” shares a 1500-watt RMS power rating with the popular Meso 15”, it stands out by delivering exceptional peak loudness at targeted frequencies (SPL). In contrast, the Meso 15” 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 15” outside our recommended box specifications (2.0 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 15”, 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 15” excels in delivering consistent loudness across all frequencies, the Thermo 15” focuses on achieving exceptional SPL peaks. Although the Thermo 15” sacrifices some bandwidth compared to the Meso 15”, 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 15” stands as your ultimate choice.
