3 WideSphere Make Every Seat the Best Seat with WideSphere MB Quart s desire to offer the best in audio reproduction prompted our engineers to develop a unique tweeter technology called WideSphere. The goal was to ensure that a full range of music can be experienced from almost any seating position in a vehicle. Touted as a Quantum leap in tweeter transducer expertise, WideSphere is the result of years of acoustical research, exhaustive engineering and the use of innovative materials. Essentially, WideSphere takes tweeters from a very linear approach into a new, expansive direction so that the exhaustive need for staging or imaging is far less necessary with WideSphere s 180 sound dispersion technology. The success of this breakthrough in transducer technology can be attributed to the use of an inverted two-piece titanium dome and the powerful neodymium ring magnet system developed exclusively by MB Quart. By creating a wide radiation angle, for the first time ever, off-axis dispersion measurements are nearly identical to on-axis. WideSphere technology is available in MB Quart s Premium, Reference and Discus series speakers and new this year in Premium and Discus series tweeter kits. Look for the WideSphere logo throughout this catalog for products that feature this amazing technology. CONVENTIONAL TWEETER WIDESPHERE TWEETER Listening Angle Ideal Response 4 5

5 REMIUM PREMIUM High Levels of Performance Premium subwoofers offer the highest level of performance for both small sealed and ported enclosures. When MB Quart decided to design a premium subwoofer, they knew that it had to meet the high expectations of the MB Quart customer. One look at the new PWH subwoofers and the Premium characteristics are clearly evident. The honeycomb reinforced cone and high roll surround provide the strength and excursion necessary for proper low frequency performance. The 3 voice coil is mated to a custom molded cone support that spreads all of the piston s energy effectively across the entire cone body. This improves sound quality by reducing cone distortion, which can be common in larger subwoofers. All connections are mounted on one end of the woofer and simple jumpers allow for series and parallel wiring without complication. A trim ring adds a finished touch to an already incredible looking sub.

6 REFERENCE Truly Unique The RUI Reference speaker is designed for when OEM speaker mounting depth is fixed at very shallow dimensions, yet high-performance and quality are still essential. The Reference line is truly unique. With the RUI speaker, it steps up where other shallow-mount speakers fall short. Our engineers have discovered that by mounting the neodymium magnet in front of the speaker cone, together with using a standard depth (full excursion) cone and a durable, full-sized composite basket, there is no compromise to the high-end performance that is expected from MB Quart. Combined with the technologically-advanced WideSphere tweeter, this series is the ultimate in high-performance speakers.
