The Yamaha DHR15 15" Active PA Speaker Pair with Stands bundle comes with a pair of Yamahas brand-new active 15-inch PA speakers. As with all of the DHR-series speakers the custom-designed transducers within the DHR-15 are built to get the very best out of the speaker. High SPL outputs powerful bass and a precision 1.4-inch compression driver with minimal distortion and maximum clarity are par for the course with this range. The Yamaha DHR-Series boasts the same rugged plywood enclosures as their acclaimed DZR-series ensuring robust and powerful performance from them with minimal vibration from the enclosure getting between you and the performance. With cutting-edge DSP technology Yamaha have developed FIR-X specifically for this range of speakers. This means that instead of the typical crossover filters seen in most loudspeakers linear phase FIR (finite impulse response) filters will provide a consistent phase and frequency response whilst also adjusting the time alignment between the HF and LF transducers. This minimises phase distortion and means that the dips and peaks typically seen around the crossover frequency are prevented in favour of a clear defined transition unlike any youve heard before. This bundle makes it easy to get the most out of the DHR15s angled speaker pole socket straight away to get a setup that fits your venue.
