Pioneer TS-W256R
10″ subwoofer · 4 Ω · 300 W RMS
The Pioneer TS-W256R is a 10″ subwoofer. With Qts 0.65 and EBP 48 it suits a sealed box: tight bass in a small enclosure; a ported box would need a lot of volume. Modest excursion (Xmax 0.25″) — for clean sound at moderate levels, not for SPL competitions.
