The H-310C 10-Inch heavy duty woven cone offers incredible strength and dispersion advantages compared to a traditional woofer. It enables superior acoustical quality, improved mid-bass, extreme durability under high stress conditions, and is less susceptible to blowout (even when being driven at the highest levels). The heavy duty 10-Inch woofer in the H-310C also enables this speaker to deliver low frequencies down to 24 Hz (+/- 3dB). Each HT-310C includes a pivoting 1-Inch liquid-cooled titanium tweeter and pivoting 2 1/2-Inch midrange that deliver highs beyond the audible range and smooth, accurate mid frequencies. H-310C speakers are packaged with both a white cloth decor grille (offering a clean, classy look for those not interested in painting their grilles), and a paintable metal grille (for those who want their speaker to completely blend in with a colored ceiling). White speaker baffles augment contemporary cosmetics. Mounting tabs are included for easy installation.
