Wooden Horn Series

M28-III

2×8 inch Horn 2-Way

The M28-III speaker is an in-wall, flush-mounted speaker with a dumbbell design. It features a rich and dense midrange, with the high-frequency horn taking over at 1.6kHz. A first-order slope combined with perfect physical time alignment achieves perfect coherence in the crossover region. Off-axis performance is textbook perfect.

It utilizes a 44-core high-sensitivity compression tweeter and two 8-inch woofers with a power rating of up to 500W.
