Anleitung Zusammenfassung


The SPG555 features our patented-pending 3.5-inch RV C™ (Removable Voice Coil) allowing you to either change the impedance of the subwoofer or repair a defective voice coil; without having to remove the SPG555 from its enclosure! By removing six screws, you can simply slide out the RV C™ and replace it with a new one. In addition, the SPG555 features our SPS™ ( S o f t Part System) allowing the user to replace the entire cone/surround/spider assembly should they ever become damaged. The SPG555 incorporates a unique cone profile. The race track design allows the SPG555 to fit where other woofers cannot, giving you the ability to install the SPG555 in an area that would normally would limit you to using a 10-inch sub- w o o f e r. The area of the cone, 555cm2, is larger than a standard 12-inch subwoofer—simply put, greater cone area for greater output. A 3.5-inch diameter voice coil combined with Boston Acoustics' patented RadialVe n t® cooling allow the SPG555 to handle an amazing 1000 watts RMS. Generally conventional high output subwoofers rely on massive magnets that dramatically increase their weight. The SPG555 uses a powerful neodymium motor structure that is significantly lighter than ferrite motor structures, keeping the total weight of the SPG555 to only 26 lbs. Like the highly acclaimed Boston Acoustics G5 line of subwoofers, the SPG555 can be completely disassembled to allow customization. You can paint, powder-coat, or chrome the SPG555's basket and heatsink to customize the appearance of the SPG555 for a custom installation. Take a few minutes and familiarize yourself with the contents of this manual. In addition to basic set-up requirements for the SPG555, you will also find several enclosure designs that allow you to tailor the performance of it to your specific design goals. Whether you are looking to build a vehicle for accurate reproduction or the production of mind-blowing bass, the SPG555 is up to the task. Attributes of each enclosure are highlighted on each design page and all three designs should be considered before making a decision on which one to build as the enclosure design will radically effect the end result. Regardless of enclosure chosen, the SPG555 truly defines reference level performance.

It will offer the best overall response across the low frequency audio spectrum, great transient response, and will allow for the most seamless integration between the subwoofer system and front speakers. It is also half the size of the sound quality ported design minimizing the space that needs to be dedicated to the subwoofer enclosure. Sealed Enclosure Specifications Recommended Enclosure Volume*: 1.0 ft3 (28.3L) Q-Tune™† (Highpass and Q Setting): 25Hz @ 0.707 Sealed Enclosure Example Gross Volume: 1.0 ft3 (28.3L) Internal Height (H): 10 1.2" (26.7cm) Internal Width (W): 13" (33.0cm) Internal Depth (D): 13" (33.0cm) General Information for both Sealed and Ported Designs *All enclosure dimensions are internal and include basket and port displacement The above enclosure shape is an example and these dimensions can be modified provided that the exact internal volume is retained 3.4-inch thick M.D.F. is recommended as a minimum †Q-Tune™ is a feature found on Boston GT Amplifiers Sound Quality Ported Enclosure Sound Quality Ported Enclosure Explanation The use of low tuning allows the SPG555 to deliver much stronger low bass energy when compared to the sealed enclosure. Use of a smaller volume combined with low tuning allows the ported sound quality enclosure to produce a relatively flat response down to 30Hz while delivering solid impact at high output levels.
