Concert Grand SI

Three years in the making; significantly improving on what was already considered by many industry insiders to be one of the greatest dynamic loudspeakers ever developed.  The old Concert Grands were legendary for their tonal accuracy, dynamic ease, and dimensional palpability.  The new speakers are designed and bulit by the same team as before to possess those same ESP attributes while achieving significantly better low frequency extension, midrange clarity, low-level detail and microdynamics, and speed.  In addition to using 10 expensive state-of-the-art drivers per side, with different and optimized compound driver configurations for each of the bass and midrange units, the new speakers use a totally redesigned and more phase-coherent crossover, better crossover parts, and much more sophisticated cabinet construction, all necessary in order to take advantage of the the new driver configurations and specs.  As great as the old Concert Grands were, the new speakers are in a different league altogether.

Specifications:

	all new drivers, crossover, internal wiring, and crossover parts, adding even more openness, transparency, and low-frequency impact to the product’s already legendary tonal accuracy, dynamic ease, and dimensional palpability
	new compound-driver woofer and midrange units for greater low-frequency extension and lowered distortion.
