Celestion TSQ1845 18" Neodymium SubwooferTen Key Features that add up to a new standard in LF driver performance
The Ten² development initiative meticulously reexamined every aspect of driver design, implementing and validating a series of progressive refinements. These cumulative enhancements work together to set a new benchmark for performance and durability in professional low-frequency loudspeakers.
Precision Tuned VentingPrecision Tuned Venting (PTV) harnesses the cooling effects of constant airflow in a set of precisely dimensioned vents, enabling cooling around the coil and magnet assembly to be significantly improved – by up to 80C compared to conventional designs.
Reduced Power CompressionHighly efficient PTV cooling delivers additional reduction in power compression (loss of driver efficiency), as well as lower thermal stress on the voice coil, leading to improved performance, endurance and longevity.
Polysiloxane Laminated Dual SuspensionPolysiloxane (a silicone polymer) is sandwiched between two resin- impregnated layers which enables the laminated suspension to be worked much harder without losing stiffness, giving better coil control, making DC shift less likely and increasing speaker longevity.
Reconfigured Magnet Assembly For Greater ExcursionA re-configured magnet assembly allows much greater cone excursion before damage occurs (Xmech) and best-in-class Xprotection (the distance the coil and cone move, measured to the point where both Bl and Cms have both reduced to 30% of their resting value).
Convergent Motor Strength & Mechanical ComplianceElectrical motor strength Bl and mechanical compliance Cms reach their defined Xprotection limit at practically the same point: achieving a low distortion performance even during high excursion.
Custom Voice Coil StructureCelestion winds its own voice coils using proprietary adhesion and voice coil structure solutions to maximize product lifespan and performance longevity.
Enhanced Moisture ProtectionA water-based solvent is applied to one or both sides of the loudspeaker’s cone (depending on speaker model and desired application). This significantly improves the driver’s ability to resist direct exposure to water and higher levels of humidity, and also improves product durability.
Laser-Cauterized Lead Out Wire HolesWeaving lead out wires into the suspension through laser cut holes reduces ‘whipping’ and lessens the fatigue on wires and joints caused by high power and cone excursion.
Multi-layer Inside/Outside Coil WindingsCelestion’s voice coils are wound inside/outside in multiple layers, to maximize cooling potential with the greatest amount of surface area exposed to free air. This further contributes to the reduction of both power compression and thermal stress.
Precision built in the UKTSQ drivers are built on the newly-commissioned, robotically-assisted production line at Celestion’s UK-based loudspeaker research and manufacturing facility, and rigorously tested in line with an exacting list of performance criteria.
BUILD THIS: 18" Bass Reflex Enclosure Featuring the TSQ1845Loudspeaker cabinet designer Bill Fitzmaurice has developed a bass reflex enclosure specifically for the Celestion TSQ1845, an 18" cast aluminum chassis neodymium magnet low-frequency driver. Built from 12mm plywood, the design maximizes performance while keeping the cabinet compact and lightweight.
The TSQ1845 features a 4.5" copper voice coil, delivering 3600W of continuous power and 97 dB sensitivity. As part of Celestion’s Ten Squared (TSQ) series, this 18" driver is precision-engineered and assembled in the UK to provide exceptional performance for the most demanding professional sound reinforcement applications.
