Frequently Asked Questions - Bass Xtreme BXW-124 Soundstream

What is the impedance of the Soundstream Bass Xtreme BXW-124?

The BXW-124 has a dual 4-ohm voice coil (DVC 4Ω). It can be wired in series for 8 ohms or parallel for 2 ohms.

What are the recommended enclosure volumes for this subwoofer?

For a sealed enclosure: 0.25-0.75 ft³ (optimal 0.50 ft³). For a ported enclosure: 2.25-2.75 ft³ (optimal 2.50 ft³) with a 4" x 12" L port tuned to 31.1 Hz.

What is the RMS and peak power handling?

RMS: 800 watts. Peak: 2400 watts. Ensure your amplifier delivers clean power within these limits.

What are the physical dimensions of the BXW-124?

Overall diameter: 12.20 inches. Mounting diameter: 10.94 inches. Mounting depth: 5.12 inches. Cutout hole is typically 11 inches.

What materials are used in the cone and surround?

The cone is made of spruce pulp with UV and chemical protection. The surround is extended excursion polyether foam, also UV and chemically treated.

How do I wire the dual voice coils?

Wire coils in series for an 8-ohm load (connect positive of one coil to negative of the other, then remaining terminals to amp). Wire in parallel for a 2-ohm load (connect both positives together and both negatives together).

Can I use a mono amplifier?

Yes, as long as the amplifier is stable at the final impedance of your wiring (2 or 8 ohms). Most mono amps are 1-ohm stable, so 2 ohms is fine.

What is the recommended break-in procedure?

Play the subwoofer at moderate volumes (50-75% of RMS) for 10-20 hours with music containing a variety of frequencies. This helps loosen the suspension for optimal performance.

Does the subwoofer come with a trim ring?

Yes, it includes a 1-piece gasket/trim ring with concealed mounting holes for a clean installation.

How should I clean and maintain the subwoofer?

Use a soft dry cloth to remove dust. Avoid liquid cleaners. Ensure the enclosure is sealed properly and check connections periodically.

Vehicle conditions, amplifier, music preferences, & other variables make it difficult to give you exact dimensions for an enclosure deisgn. For enclosure designs tailored to your specific needs, please contact us at [e-mail], or 1-800-724-1377.

All enclosures should be made of .75" (3/4") material only. When possible, make the baffle 1.5" (1 ½) thick and add .75" (3/4") to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out reflections within the enclosure.
