Description of R2-SB12V:

The next generation of sound performance is here with the new R-Series Halo Preloaded Subwoofers featuring the new R-Series “R2” subwoofers for more accurate and authoritative bass.

Features:

• Unique ProLink™ Design
  ProLink™ is unique to Alpine and allows you to link two R2-SB12V enclosures together using an optional KTX-H12 linking kit to create a dual subwoofer enclosure.
• Stand Out in the Crowd
  Drawing inspiration from the sleek, tapered lines and clean silver finish of the Alpine Halo display, the R2-SB12V shares the same unique, curved edges outlined by a silver trim and a metallic front baffle for a matching system aesthetic.
• Improved Performance
  The new R-Series subwoofers now feature larger, double-stacked magnets that contribute more motor force for deeper bass and tighter bass control compared to the previous generation.

Description:

The R-Series amplifiers utilize Alpine’s advanced amplifier platform that takes the classic Class-D amplifier circuit and adds dual post-filter feedback loops for unmatched accuracy and control. This technology., originally launched in the premium X-Series amplifiers,, produces efficient power with enhanced dynamic range, qualifying the R-Series amplifiers to be Hi-Resolution Audio compliant.

PROPER SOUND STAGE
This new technology minimizes audible imperfections like excessive phase shift and internal noise which can deteriorate sound quality.

NEXT LEVEL SYSTEM BUILDS
R-Series amplifiers have a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Improve the sound quality of component speakers by ditching your passive network. Avoid added phase shifts and power losses by individually powering each component and assigning your own frequency bands for the incredible sound you’re looking for.

THE LOUDEST FAMILY ON THE BLOCK
The “R” line of speakers and subwoofers have a heritage of sound quality you can hear from a block away, and the newly added R-Series amplifiers are no exception. Aside from their best-in-class performance, these amplifiers are tuned to emphasize the characteristics of the R-Series speakers and subwoofers, giving you that legendary R-Series experience.
