X2 Alu 500W construction kit. Robust but reasonably sized subwoofer with a new Aluminum element!
The X2 Alu series uses Peerless's XXLS-10 Aluminum subwoofer element, which has already become a concept. It has a very strong double magnet and a long-lasting voice coil. The stroke length of the element is as much as 26 miles. XXLS-10 is an abnormal element and can be used in many. in enclosure applications. If you want the playback to extend low enough to 20 Hz, the recommended Enclosure volume is 40-60 liters in the reflex enclosure. In the example, we used a 50-liter enclosure tuned to 23 Hz. When the housing is filled with polyester cotton, lightly compacting to a full excitation frequency is practically about 21 hertz. From the point of view of sound quality, it would be even more advantageous to tune the tuning frequency of the housing even lower. In a 50-liter enclosure, 18-20 Hz would be the optimal tuning, but the increasing length of the tube easily becomes a problem. Of course, the housing can be designed to fit even a long pipe. XXLS-10 Alu requires a good current carrying capacity of the amplifier, the amplifier must be sufficiently efficient and of high quality.
For the kit, you can select the desired amplifier from two different HT-Amp D-class active modules. The HT-Amp 600.1 gives a continuous power of 300w, while the 1000.1 powers are 500w / rms. The smaller amplifier is used sparingly in smaller spaces. When you want to get the most out of the element, we definitely recommend the more robust 500w model! (NOTE! HT-Amp fixed 25Hz subsonic)
According to the frequency response measurement, the reproduction reaches 20 Hz. The sound pressure of the X2 is already sufficient for a slightly larger space. The compression is exceptionally low, so playback remains dynamic even at high listening volumes. The X2 Alu is a high-end subwoofer that meets the needs of the discerning listener, whether it’s for home theater use or listening to music. The X2 is perfect for normal home use. For years, Peerless's predecessor model XLS-10 has been by far Finland's best-selling home subwoofer element, and no wonder. Rarely is the price / quality ratio in any product so good.
The set includes the following parts for one (1 piece) speaker:
- HT-Amp 1000.1
- Peerless XXLS-10 Aluminum element
NOTE! Does not include reflex tube. We recommend, for example, the JetSet 70 as a tube.
We recommend ASPA damping material as the damping material.
- The internal volume of the case is approx. 50 liters
- External dimensions of the sample housing
(LxWxH) 420 x 420 x 600 mm
- Material 18-25 mm, front plate 25-35 mm.
- The amplifier is recommended to separate the bass from the air space with a partition
If you do not want to make the case yourself, you can order it ready-made. The pattern wood makes speaker cases from MDF or glulam according to the customer's wishes. The selection includes almost all the building kits sold by Hifitalo, and if necessary, you can also submit the speaker drawings yourself. See the link below for more information and prices.
