PB12 is the predecessor of SBP12.
SBP12 Highlights: (from manufacturer's website):
* Lambda Motor with Full Copper Faraday Sleeve (FCFS)
* Extremely low and linear inductance
* Wide bandwidth and detailed midbass
* High Xmax with clean suspension travel
* High Efficiency upper/midbass
* Designed for sealed box applications
* Also ideal for Automotive Infinite Baffle use
The SBP Series woofers are low distortion, high Xmax, wide bandwidth bass drivers designed for sealed box applications. They work well in a variety of applications including subwoofers, bass/midbass drivers in 2way or 3way systems, and automotive infinite baffle applications. The Lambda Motor means they have very low/linear inductance extending cleanly to over 500hz, while the high Xmax allows them to play the lowest notes with authority. SBP woofers have been used in high end recording monitors, home theater subwoofers, and extremely high end hi-fi systems retailing for upwards of $100,000. When you want the most accurate woofer for sealed box applications, look no further than the SBP Series.
The SBP Series are also the ultimate option for automotive infinite baffle use. They have a larger motor then the IB-AU Series for more efficiency in the upper bass region where there is very little cabin gain. This allows them to integrate and work extremely well with the cabin gain in your vehicle. You will not find a lower distortion woofer for Automotive Infinite Baffle applications.
