SHOP BY CATEGORY About Us CT Sounds was founded in early 2013 by Coleman Thedinger at the age of 21. The vision was to create a company that could offer high-quality car audio products at an affordable price while offering industry leading customer service. Coleman’s love for car audio was not just about hearing sound, but experiencing it. CT Sounds was created to be more than a manufacturer of car audio products, it’s a way of expressing yourself in conjunction with your favorite pastime. In 2019, Coleman died unexpectedly at the age of 27, and his father, Bart, took over ownership of the company. Many people would have sold the company but Bart believed in his son’s dream “a way of expressing yourself with your favorite pastime”. If he gave up the business he would be giving up the biggest connection he had with his son - music. After Coleman’s passing the business struggled greatly and almost filed for bankruptcy in late 2020. In November 2020, Coleman’s younger brother Calvin Thedinger bought into the business at age 23. Calvin, who graduated with an engineering degree from Texas A&M University, was working his first job out of college making $80,000/year as an income statement analyst for Baker Hughes. Calvin gave this up to make $0/year and work day and night to carry out his brother’s vision for CT Sounds.

Our goal was to engineer a 500-watt 10” shallow-mount subwoofer with a mounting depth below 4” that was suitable for both sealed & ported enclosures. To achieve this, we focused on the EBP (Efficiency Bandwidth Product). As a general rule, EBP 100, is used only for ported enclosures. EBP = FS/QES. Quick Facts: RMS Power: 500 Watts MAX Power 1000 Watts Voice Coil Configuration: Dual 4 Ohm Use Cases: Sealed & Ported Enclosures Our 1st prototype utilized a 61.1 mm voice coil & 50 oz magnet resulting in a high QES rating of 1.03 and low EBP of 38.22. The 2nd prototype utilized a 50.8 mm voice coil & 50 oz magnet resulting in a slightly lower QES rating of 0.831 and a slightly higher EBP of 47.37. After the 1st and 2nd prototypes, we determined a larger motor assembly was needed to provide a more controlled electrical system (lower QES). This led us to invest in a custom-tooled basket (used in the final prototype) to keep the mounting depth below 4”. The 3rd and final prototype uses a 61.1 mm voice coil & 70 oz magnet resulting in a reduced QES rating of 0.569 and a balanced EBP of 69.19. In testing, we ran into mechanical noise due to the larger motor assembly and voice coil in a confined space. Therefore, we invested in a custom-tooled cone to maximize the excursion capability by creating an equal distance between the cone, spider, and bottom plate. The result is a 10” shallow-mount subwoofer that is extremely responsive in both sealed & ported enclosures.

CT Sounds CT-LC2 2-Channel Premium Line-Out Converter with BassLift

By |2026-07-23T12:00:22+00:00July 23rd, 2026|

Product Description:The CT-LC2 is a convenient way to upgrade your car audio system without replacing your factory head unit. This premium LOC (Line Out Converter) converts the high-level signal used to play factory speakers into a low-level RCA input to send to the amplifier(s), allowing you to use the stock radio as the signal source for your aftermarket amplifier(s). Alternatively, this device can “upgrade your radio” while still utilizing your factory amplifier. Many vehicles’ factory radios have navigation and climate controls built-in; therefore, you can no longer easily replace your vehicle’s factory radio with an aftermarket radio to use as the source for your amplifier(s). Furthermore, many manufacturers reduce the bass output at high volumes to protect the stock speakers – you may have noticed at a certain volume level, your speakers don’t produce more “bass” as you continue to turn up the volume. The CT-LC2 allows you to maintain your factory radio controls and restores bass frequencies with its “BassLift” technology. The CT-LC2 features a full-range main output and a low-pass (1000 Hz) bass output. Use the CT-LC2 to quickly add a subwoofer to your factory system or a compact front stage plus subwoofer setup. CT Sounds “BassLift” technology can compensate for factory bass roll-off or as an enriching boost to the low-end. Included with the CT-LC2 is a 34-page product manual that walks you through step by step how to install the device. If you have any questions or concerns during the installation process, please reach out to our tech-support team by emailing hello@ctsounds.

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.
