<p><strong>Features of R2-W8D2:</strong></p>
<ul>
<li><strong>New Motor Structure</strong><br>
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.</li>
<li><strong>Oversized Dust Cap</strong><br>
The new hybrid poly ceramic composite dust cap ensures rigidity while also providing incredible internal damping (vibration absorption) to smooth out the bass response and reproduce tight bass.</li>
<li><strong>Increased Accuracy</strong><br>
Alpine's High Amplitude Multi-Roll (HAMR) Surround Technology allows the cone to efficiently move air while staying cool resulting in incredible accuracy from the subwoofer.</li>
