"A subwoofer of the quality of the TL-Sub is quite simply pure, unadulterated luxury - not because of the purchase price necessarily, because the price is more than fair even when you include the necessary electronic wizardry."
"Anyone who has ever heard the TL-Sub in action will know what subterranean bass can really sound like. As car tuners often claim: big engines can only be beaten by even bigger engines. In other words: size does matter."
