Product description

SUB XPP3 Alu. Performance with two passive radiators in a small enclosure! XPP3 Alu is a modified version of the XP3 Alu model, in which the tuning is implemented with two passive radiators instead of one. The reason is that at high volumes, when using two radiators, the performance is better. The sound quality of the radiator increased by two to no other. When two passive radiators are used, the excitation frequency changes compared to a single passive element system. Therefore, it is advisable to increase the enclosure volume by 10-15 liters. In the example housing, the Passive Radiators are placed on the sides of the housing and the actual element in front. The element can also be placed in the bottom of the housing, but then you have to make your feet or put the wheels in the housing. A sufficient distance between the floor and the floor is 50-100 mm. Increasing the weight of the housing is recommended. The mass can be increased, for example, with a lead weight which is screwed inside or outside the housing. Without additional mass, the housing can move at higher volumes.

The construction kit includes HT-Amp's powerful 1000.1 model which gives 500w of continuous power. The device also has good adjustments. The sound quality of the XPP3 Alu does not differ much from the XP3 Alu model, but the model implemented with two passive radiators at high volumes works better. XPP3 Alu is a subwoofer for the discerning enthusiast and is suitable for both listening to music and home theater use.

(NOTE! HT-Amp fixed 25Hz subsonic)
