The Truffle-KTR26 is the largest model in the compact line of Truffle subwoofers applied when low-end sustain is needed. The source subwoofer has a frequency range of 45 Hz to 150 Hz and is comprised of a single 6.5″ driver with passive radiators. For a hidden installation, the Truffle-KTR26 was designed with an 12″-long cylindrical speaker box equipped with one 6.5″ active driver on one end and one symmetrical 6.5″ passive speaker on the opposite end, perfect for an omnidirectional low-end source. This subwoofer provides the low-end frequencies for the Azimut-KAMUT2V25 audio system.
