For theater systems based on the more compact 803 D4 or 804 D4, the HTM82 D4 center-channel speaker is the perfect solution. Its more compact midrange drive unit is ideally sized to match those of its siblings. *Stand(s) not included.
The new HTM82 D4 may be our most compact center-channel speaker, but it shares the design DNA of its larger siblings, including the Reverse Wrap cabinet and Matrixâ„¢ bracing. The combination of the two technologies ensures a quieter, more acoustically efficient and better-sounding speaker than ever.
