The SACN1-1000 replacement crossover keeps your PA subwoofer system running when the unexpected happens. Designed specifically for Seismic Audio's Enforcer II passive subwoofer, this crossover network ensures you're never stuck with dead low-end during critical performances.

This passive crossover filters frequencies at 125 Hz with an 18 dB per octave slope, directing the proper frequency range to your subwoofer driver while protecting it from damaging mid and high frequencies. The precise filtering maintains clean bass response and prevents driver damage from out-of-range signals.

The 125 Hz crossover point works perfectly for live sound reinforcement, providing tight low-end extension without muddying the midrange from your main speakers. The steep 18 dB slope ensures clean frequency separation between your subwoofer and tops. At just 1.43 pounds, this compact crossover network fits easily in your repair kit or road case.

Perfect for touring musicians, sound companies, and venues that can't afford downtime during events. Whether you're running sound for a 200-person wedding reception or a club gig, having this replacement crossover on hand means you can restore full-range sound in minutes rather than canceling the show.

Installation requires basic soldering skills and access to the crossover compartment in your Enforcer II subwoofer. All necessary mounting hardware and connection points match the original factory crossover.

Seismic Audio backs this replacement crossover with a one-year warranty and ships fast to get you back up and running. Professional reliability at a price that makes sense for your repair inventory.

Technical Specifications

Frequently Asked Questions

Is this crossover compatible with other subwoofer brands?

This crossover is engineered specifically for the Seismic Audio Enforcer II passive subwoofer and may not work properly with other brands or models. The 125 Hz crossover point and 18 dB slope are optimized for the Enforcer II's driver specifications and cabinet tuning. Using it with different subwoofers could result in poor frequency response or potential driver damage.

What tools do I need to install this replacement crossover?

You'll need basic soldering equipment, wire strippers, and a screwdriver to access the crossover compartment in your Enforcer II subwoofer. The installation requires disconnecting the original crossover and soldering the new unit to the existing input and driver connections. Basic electronics repair skills are recommended for proper installation.

How do I know if my subwoofer's crossover has failed?

Common signs include no bass output, distorted low frequencies, or the subwoofer suddenly becoming very quiet compared to your main speakers. You might also notice the crossover getting unusually hot or see visible damage to capacitors or inductors. Testing with a multimeter can confirm component failure in the crossover network.

Can I upgrade my subwoofer's performance by changing the crossover point?

This crossover is designed to match the original Enforcer II specifications with a 125 Hz crossover point. Changing to a different crossover frequency would require a different crossover network and could negatively impact the subwoofer's performance. The 125 Hz point provides optimal integration with most full-range PA speakers.

Should I keep spare crossovers for my PA system?

If you're a touring musician, sound company, or venue that relies on consistent bass response, keeping a spare crossover is smart insurance. Crossover components can fail from age, heat, or power surges, and having a replacement ready means minutes of downtime instead of cancelled shows or disappointed clients.
