Alpine R2-SB10V Halo Series 10

This preloaded ported enclosure houses a 10-inch subwoofer built with a Kevlar-reinforced pulp cone and Santoprene rubber surround. It handles 750 watts RMS and delivers a frequency response from 26 to 200 Hz for deep, accurate bass reproduction in a vehicle audio system.

Upgrade from single subwoofer setups

The enclosure is tuned to 36 Hz to maximise low-frequency output from a single box. When greater impact is required, a second R2-SB10V can be added using the optional KTX-H10 linking kit to create a dual-subwoofer system with double the bass output.

Ported enclosure tuning limits

The ported design optimises output around the 36 Hz tuning frequency, so performance drops below 26 Hz and above 200 Hz. The 2-ohm wiring requires an amplifier stable at that impedance, and the fixed enclosure volume prevents retuning for different frequency preferences.

Questions about this item

What mounting hardware or brackets are needed to secure the 10-inch ported enclosure in a vehicle?

The enclosure is built from 3/4-inch MDF with black carpet covering and includes integrated mounting points; use standard automotive-grade bolts and washers through those points to fasten the box to the cargo floor or rear deck.

Which wiring mistake causes the R2-W10D4 driver to present the wrong load to the amplifier?

The subwoofer is pre-wired for a 2-ohm nominal impedance; connecting the leads in series instead of the factory parallel configuration will raise the load to 8 ohms and drastically reduce output.

When should the Kevlar-reinforced pulp cone and Santoprene surround be inspected or replaced?

Inspect the cone and surround annually for tears, separation or stiffness changes; replace the driver if the surround shows cracking or the cone develops soft spots that distort the 26-200 Hz response.
