Phoenix Gold RX2 12S
12" Single Voice Coil 4 Ohm
Phoenix Gold's RX2 subwoofers feature long wound 2” coils (half an inch diameter larger than standard woofers) for mechanical stability and power handling while allowing for 25mm of peak-to-peak excursion — resulting in clear, dynamic bass, especially within the sealed or vented enclosures experienced in your automobile. These subwoofers also minimize distortion by reducing resistance and heat thanks to their KlaraForm Vented Kapton Former tech, paired with Torriform Voice Coil technology that dissipates heat.
Conservatively rated at 200w RMS, the Phoenix Gold subwoofers are available in both single and dual 4 Ohm voice coil configurations, with powder-coated steel baskets that help to defeat unwanted resonance. Proprietary Phoeniroll surround-tech promotes linear motion, while UNICAP technology provides the stiff piston needed to create pronounced efficiency and sensitivity.

Phoenix Gold subwoofers are over-engineered and overbuilt in virtually every way conceivable. It is important that the subwoofer’s enclosure is built to these same exacting standards. The enclosure must be constructed of at least .75 inch MDF. Screws or air staples are excellent construction fasteners when used with a strong bonding “yellow” woodworking glue that can fill joint gaps. Be sure that the enclosure’s panels are airtight at all joining seams. Lining the walls with a polyester matting 1 to 3 inches thick is sufficient. RX2 subwoofers have vented pole pieces, we recommend leaving a minimum of 0.5” clearance behind the subwoofer to allow proper air movement and cooling of the voice coil.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.
Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.
Recommended Enclosure Specifications
Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.
Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".
Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.
Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.
