TF1525 8 Ohm [Open Box]

The Celestion TF1525 is a 15-inch bass and mid-range driver built for PA cabinets that need real output without added design complexity. Rated at 250W continuous power with a 500W program rating at 8 ohm impedance, it delivers a sensitivity of 98dB, converting amplifier power into loud, clear output efficiently across venues of varying size. A Kevlar-loaded paper cone on a polyimide former and a cloth-sealed surround give the driver a balance of rigidity and controlled movement, while the pressed steel chassis keeps the build straightforward and durable for repeated use in touring or installed sound rigs. Its frequency range spans 40Hz to 3,000Hz, positioning it well for bass and lower mid-range reproduction in a two-way or three-way system design. A ferrite magnet weighing 1.2kg and a 64mm round copper voice coil support the driver's power handling without adding excessive overall weight, and the complete Thiele-Small parameter set, including an Fs of 47.6Hz and a Vas of 148.41 liters, gives cabinet designers the specific data needed to build an enclosure tuned around this driver rather than relying on generic box dimensions. For system builders assembling a mid-format PA cabinet or subwoofer that calls for a 15-inch ferrite driver with dependable power handling, the TF1525 offers a well-documented, straightforward option.
