Dispute Focuses on Patent
THX filed a lawsuit against Apple Corp. in US District Court, Northern District of California, San Jose, CA, on March 14, 2013, alleging that Apple is using patented THX speaker technology in select iOS mobile devices and in iMac PCs. The patent in question is a 2008 THX US Patent 7,433,483 for a slot-loaded speaker that can boost sound output by controlling directivity (see Figure 1). The patent specifically describes a woofer whose output fires through a narrow slot resulting in a wide horizontal dispersion angle and a narrow vertical dispersion angle. It should be noted that a narrow vertical dispersion pattern is part of the certification standard applied to THX-certified home theater speakers. The configuration described in the patent is alleged to have been incorporated into the Apple iPad, the iMac, the iPhone 4, and other select Apple products. THX maintains that the infringement caused monetary damage and irreparable harm to THX. Apple’s last day to meet and confer with THX counsel and the court over initial disclosure, an early settlement, and other stipulations is May 14, 2013. The deadline for initial disclosures is June 7, 2013. The initial case management conference is scheduled for June 14, 2013.

Triad Offers New Loudspeaker System
Custom loudspeaker manufacturer Triad Speakers has released its new Cinema Reference loudspeaker system for larger screening rooms and dedicated home theaters. The CR-2 includes a 15” woofer, two 8” midranges, and a proprietary horn-loaded air-motion transformer tweeter—all sourced from premium European professional driver manufacturers (see Photo 1). It is the company’s loudest loudspeaker to date, exceeding 120 dB at 1 m.
New for Triad is CR-2’s diffraction control technology (DCT) baffle design. The curved design minimizes diffraction and resonances, acts as an acoustic diffuser, and can be an on-wall or freestanding speaker. At 46” (H) × 31” (W) × 10” (D), the CR-2 fits behind an acoustically transparent film screen or an 11” deep stretched-fabric wall. It can be wall mounted with up to 12° of toe-in adjustment or used as a freestanding product with the optional floor mount. Finishes include flat black, real wood veneer, and custom colors. The CR-2 costs $15,000. Availability is planned for spring 2013. VC
