JL Audio 10W0v3-4 10" 25 cm W0 Series Auto-Subwoofer Treiber 4 Ohm 300 W RMS

Dropped this into a sealed 1.25 cu ft box and the excursion is seriously impressive for a 300W driver. The linearity through the midbass range cleans up what my old sub used to muddy. Definitely wakes up the low end without breaking the bank.

Bought this to replace the stock driver in my sealed box and the 4-ohm load matches my amp perfectly; the 25cm frame dropped right in. Excursion is tight and controlled even at lower volumes, though it needs a solid break-in before the linearity really shows.

The excursion on this thing is seriously impressive—it moves a lot of air for a 10-inch, and the linearity keeps the bass tight even when I push it hard. Hooked it up to a 300-watt amp and it’s been flawless for a few months now, no distortion at moderate volume.
