Mark Audio Alpair P12 - DIY 3 chambers cabinet.

This is my real experiment. I used the Mark Audio Alpair P12 broadband driver. The cabinet has three chambers inside, two are vented, with different frequency tuning. The cabinet has medium-sized dimensions - 45x25x40cm. Frequency range approx. 40-20000Hz (+-8db). The repruktor has a damping for high tones of 4db, because as always with full range speakers, the mids were very dominant. The sound description is thus with a darker background, but even that, highest notes are clear and clearly audible. On the contrary, the bass is tight, dense, dry and unexpectedly fast. The resulting sensitivity is around 89db, load capacity 30W. As always, the recording is made only with HP. I apologize for the low image and especially sound quality.
