The Truffle-KTR25 is the medium model in the compact line of Truffle subwoofers for deeper bass experience. The source subwoofer has a frequency range of 45 Hz to 150 Hz and is comprised of a single 5.25" driver with passive radiators. Designed to remain unseen, the Truffle-KTR25 has an 10"-long cylindrical speaker box equipped with one 5.25" active driver and one symmetrical 5.25" passive speaker on the opposite side – perfect for an omnidirectional low-end source. This subwoofer provides the low-end frequencies for the Azimut-KAMUT2L14 audio system.
