Flagship 3-way, floorstanding loudspeaker with a unique 0.78" diamond high-frequency speaker (Diamond Underhung Voice-Coil), 4.5" ceramic midrange speaker (Ceramic Underhung Voice-Coil), 11" Ceramic/Honeycomb Underhung Voice-Coil midbass speaker and 4 long-range, low-frequency 15" speakers (Low Q High Force Factor Sub-Woofers).
The speakers feature a 1-inch high–frequency driver (Carbon/Glass Neodymium), a 7-inch midrange driver (Ceramic – Concave radial magnetic Ceramic), and two 13-inch low-frequency drivers (Nomex-Kevlar Generation II Composite).
The internal structure of the RM4 housing is a unique combination of sealed chambers and several labyrinths. Using our more than 30 years of experience in the field of resonance elimination and control, we have created a special development for the RM4 that includes a multilayer platform with limited damping for the main baffle, as well as carefully tuned cavity resonances to enhance and control its own modes.
The model is equipped with an inch tweeter with a convex beryllium dome, three 1/2-inch midrange neodymium drivers and a pair of 9-inch woofers.
All Avalon Acoustics systems, including the P2.2 model, are extremely sensitive to the installation location – they should be placed with literally centimeter accuracy. All these efforts will be rewarded with a stunningly realistic sound stage.
