The QX630 in-wall loudspeaker features a sleek modern appearance with a borderless aluminum grille that protrudes less than 3/16” (5 mm) from the wall. James all-new quad tweeter array, incorporating four 0.75" (19mm) aluminum dome tweeters in a 22.5° offset array for wide dispersion, high power handling, and low distortion promises to deliver audiophile-quality where it counts. Combined with two 6.5" (165mm) high-output aluminum cone woofers, the QX630 has an impressive 94dB sensitivity with bass down to below 65Hz. A multi-element network blends the highs and lows into a smooth and wide response. The sealed cabinet design features all aircraft aluminum construction for strength, sonic performance, and suitability for outdoor/marine applications. A stainless steel grille provides protection to the components yet has a subdued visual effect, designed to be as unobtrusive as possible.
