High Definition Series Features: Custom engineered Provlarâ„ Woofers (InwallTech's new improved version of Kevlar) made especially to create a controlled excursion with amazing damping properties for unequaled bass response. Tweeters featuring Zeleniumâ„ Dome technology co-developed with InwallTech's Chinese engineers bring next generation Titanium to be less "shrill" than current offerings from mass market speaker driver producers. High Definition Series built-in speakers feature exclusive wafer-thin Rarefiedâ„ Grille, a magnetically-secured grille that protrudes only 4mm from its surroundings. Rarefied-Grillesâ„ have nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms. Quality controlled with trade secret comprehensiveness to ensure perfect performance among all our speakers. Phonalic PCB crossovers help reach unparalleled accuracy and near-zero distortion. Aim able swivel Zelenium-Domeâ„ tweeters for greater accuracy and more realistic imaging. Durable, CAD (computer aided design) modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound. Includes a boundary compensation switch that allows the sound to be precisely tailored to counteract the effects of being installed too close -- or too far from, a corner. The result is optimum sound from any installation location. "Finally, our flagship line of speakers are here! This HD line of speakers are very good....and very good for the price. We should sell these for more, but we can't in good conscience.
