Serious Tone.
The all-new HD15 Bass Combo packs Hartke’s patented HyDrive speakers into a sleek combo design for small venues, rehearsal spaces and bedroom practice sessions, and capable of greatly enriching your low-end tone. The HD15 also maintains Hartke’s commitment to producing high-quality bass amplification with exceptional durability.

The HyDrive Design
The HD15 (15 watts, 6.5″ driver) employs Hartke’s patented HyDrive Speaker Technology that offers a carefully crafted hybrid (half paper, half aluminum) cone bass speaker. By combining the warmth and roundness of paper with the punch and attack of aluminum, the HyDrive design produces serious tone that is ideal for bass players of all genres and styles.

Solid… With Style
Packed with professional features, the HD15 combo is designed to be user-friendly and reliable for players of all levels. The combo offers Volume, Bass, Mid and Treble controls on its top-mounted amplifier panel, allowing for easy adjustments. It also features an 1/8″ stereo Aux input for playing along with your favorite tracks via an MP3 player and a 1/4″ headphone output for more intimate practice sessions. In addition, the HD15 has a built-in limiter to ensure constant amp operation at safe levels. Lastly, its solid enclosure is finished in a stylish fashion with a sleek, perforated metal grille and molded strap carry handle.

With the exceptional tone of a HyDrive speaker housed in a durable, highly portable enclosure, Hartke’s HD15 Bass Combo is able to perform at levels far beyond ordinary bass combos.
