Which ESB Tremila speaker is right for you?
If you want a ready-matched system, the 3.6K2X pairs the 3.165 6.5 inch mid-woofer with the 3.25 1 inch silk dome tweeter in a 2-way set, while the 3.6K3 extends this to 3-way by adding the 3.90 3.5 inch cone midrange and upgrading to the 3.28 1.1 inch Torcon® dome tweeter. Every driver is also sold separately as a pair, so you can build a custom system or replace a single component. The 3.6C coaxial is the simplest 6.5 inch upgrade requiring no separate crossover mounting, while the 3.69 suits 6x9 locations. For bass, the 3.WB6 and 3.WB8 are self-contained active subwoofers in MDF enclosures just 15 cm deep, with the 8 inch 3.WB8 delivering 300W RMS compared with 250W RMS from the 6.5 inch 3.WB6.
