Professionals choose the Hartke XL Series 115XL 200W 8ohm 1x15" Aluminum Cone Bass Speaker Cab because of its carefully calibrated and tuned cabinet design and high quality aluminum-cone drivers. XLs produce a smooth response along with the clear, punchy attack that changed the sound of bass. Each cabinet is built tough with a shockproof metal grill, reinforced corners, recessed carry handles and a rugged covering. This tuned, duct-vented XL cabinet and 15" low-bass driver add more bottom to your sound. Power handling is 200 watts at 8 ohms with an expanded frequency response of 30 Hz to 2.5 kHz.
