Shake, Shake, Shake the Room
What does 1000W of peak power mean to you? It means having a subwoofer that delivers rump-shaking bass night after night. It means getting class-leading power and output. To accomplish this, the TH-18s features Class-D Fast Recovery(TM) amplification. Class-D amps are more efficient and lightweight, with far less waste heat produced versus competing designs. Fast Recovery(TM) means you can occasionally push into clipping without a ton of nasty distortion. So, power is no problem... but how does it sound? The TH-18s benefits from built-in Active electronics, like a precision crossover and tuning filters for accurate bass response. Some subwoofers have decent power, but when you listen, everything sounds loose and flabby. The TH-18s delivers professional low end that you can feel... custom tuned to be tight and punchy.
