The LCR Signature monitor capitalizes on the synergies of the existing cabinet a and features a variety of improvements which are done by hand in Everett, WA. First, the tweeter is upgraded to a Vifa dual ring radiator with frequency response well past 35 KHz. All capacitors are upgraded and the internal damping materials are upgraded from dacron filling to real lambs wool. Sonic performance is palpable. Clarity and openness are greatly enhanced, while maintaining the natural tonality which is consistant throughout the LSA line.
