Pioneer HPM-50


The Pioneer HPM-50 is a bookshelf type, 3-way, 3-speaker bass reflex type system with 25cmcarbon blended woofer/midrange suspended in polyurethane foam roll edge.

The tweeter, also of carbon fibre, has been specially designed to handle long (high volume) excursions over a wide range (2.5 to 12kHz).

The HPM super tweeter delivers the same efficient, wide dispersion of highs up to 25,000Hz as in Pioneer's more expensive systems.

All drivers are mounted in die-cast aluminium frames.
