The Signature version of the LSA1OW capitalizes on the synergies of the existing cabinet and driver compliment, and features a variety of internal improvements which are done by hand in Everett, WA. All capacitors and resistors are upgraded and the standard internal wiring is replaced by very high purity monocrystal copper. Even the internal damping materials are upgraded from dacron filling to real lambs wool. While outward similarities might deceive, sonic performance is palpable. Clarity and openness are greatly enhanced, while maintaining the natural tonality which is consistant throughout the LSA line.
