PH series is represented by all-purpose, easy to handle horn loaded subwoofers. These hybrid horn subs combine high efficiency of horn acoustics with ease of traditional ported cab. They perfectly suit both large outdoor events and small venues. Unlike regular horns that need a considerable distance to show up, they fit for working in the near field.
Horn directivity gives a significant raise in efficiency and provides controll without cardioid arrays, while the sound gets no specific horn coloration and doesn't depend on the venue conditions.
The radial port eliminates distortions caused by turbulent air flows forming at the port outlet at high power.
PH21 sub is constructed upon the newest neodymium 21" speaker with a 6" coil, demodulation ring and dual silicone spider that reduces distortion. It's able to set enormous air volume in motion due to the big cone area and linear displacement.
This subwoofer has the series' maximum efficiency. It was developed as all purpose subwoofer for any kind of rent and installation application. Well balanced weight and dimensions vs efficiency characteristics and conservative choice of frequency range gives a maximum efficiency per 1Watt of power.
This compact horn cab in the volume of standard bass reflex enclosure can outperform most of subwoofers in the same class with it's punchy, deep bass and long throw coverage.
The feeling of bass immensity produced by a 21" head in a hybrid horn design is difficult to compare with that by smaller diameter speakers.
Speaker is covered with impact and abrasion resistant polyurea and can be equipped with rigging hardware.
