DESC: The S624T's stellar performance is due in large part to its 6-1/2 coated carbon fiber woofer cone and its 1 pivoting aluminum dome tweeter. The extended woofer pole piece and large magnet increase power handling while the 3/4 MDF baffle banishes resonances. A 3-position tweeter adjustment switch lets you fine-tune the speaker's response to the installation. The RotoLock® mounting system makes installation quick and easy.
