25cm 4Ω C-Type Dual Voice Coil Subwoofer (1000W)
TS-W257D4
Ultimate connection flexibility.
The TS-W257D4 offers you a variety of set-up possibilities (8Ω or 2Ω), provided that there is correct power matching between the subwoofer and your amplifier.
So, whether you are building your system from an existing stereo or mono amp, or whether you want a basic set-up with expandability potential, the TS-W257D4 will cover common impedance loads.
The IMPP™ (Injection Moulded Polypropylene) cone is constructed from a composite blend of interlaced Aramid fibres, which make it extremely rigid; yet lightweight, for low distortion and powerful bass at high sound press levels.
The speaker terminals have been placed on one side of the subwoofer, rather than on both sides as with conventional subs; this gives you greater installation flexibility.
The TS-W257D4 is for enclosed use and is also available as a 25cm 2 Ω dual voice coil model.
