Celestion TSQ1845 18" aluminium chassis neodymium magnet low frequency Speaker

If you’re looking to move from ordinary bass response to truly professional, chest-thumping low end, the Celestion TSQ1845 18" low-frequency speaker is built exactly for that next level. Engineered for demanding PA systems, clubs, touring rigs, and high-output subwoofers, this driver takes Celestion’s proven loudspeaker expertise and pushes performance, reliability, and efficiency to the extreme.

At the heart of the TSQ1845 is a rugged cast aluminium chassis paired with a high-power neodymium magnet, delivering massive output while keeping overall weight surprisingly manageable. Its advanced 3-channel tuned venting system ensures highly efficient cooling across the entire frequency band, allowing the voice coil to operate up to 80°C cooler than many competing drivers in the same class. That means cleaner bass, higher sustained output, and far greater long-term reliability when the system is pushed hard night after night.

The TSQ1845 is designed for precision as much as power. Its polyciliate laminated dual suspension provides exceptional stability and symmetrical cone movement, ensuring tight, controlled low frequencies even at high excursion. Precision-woven lead-out wires are integrated directly into the suspension to minimize unwanted motion and reduce fatigue, while the double-sided, weatherproof cone coating adds durability for both indoor and outdoor sound applications.

With a massive 1800W power rating, a 3600W continuous power capability, and a sensitivity of 96.5dB, this 18" driver is perfectly suited for high-impact subwoofer enclosures where deep, authoritative bass is non-negotiable. Whether you’re designing a club system, upgrading a touring rig, or building a serious sound reinforcement setup, the TSQ1845 delivers the kind of low-frequency performance professionals rely on.
