The SACN-152 replacement crossover keeps your PA system operational when the original crossover fails. Designed for live sound professionals, touring musicians, and venue technicians who need reliable backup components for critical performances.

This passive crossover splits incoming audio signals at 2.5 kHz with an 18 dB slope, directing low frequencies to the woofer and high frequencies to the compression driver. The precise frequency division ensures proper driver protection and maintains the intended sound signature of your PA speakers.

The 2.5 kHz crossover point and 18 dB slope ratio provide clean frequency separation that prevents driver damage from out-of-band signals. At just 0.67 lbs, this compact crossover fits easily in any crash kit or spare parts inventory. The passive design requires no external power, drawing energy directly from your amplifier signal.

Essential for bands on tour, rental companies, and permanent installations where downtime isn't an option. Whether you're running sound for a 200-person club gig or managing a house system that can't afford failures, having spare crossovers prevents show-stopping equipment failures.

This crossover is specifically compatible with Seismic Audio models SA-155T and FL-155P. Direct replacement installation requires basic soldering skills and standard audio tools - no special cables or adapters needed.

Backed by Seismic Audio's one-year warranty with fast shipping to get your system back online quickly. Professional reliability without the premium price markup.

Frequently Asked Questions

What Seismic Audio speakers is this crossover compatible with?

The SACN-152 crossover is specifically designed for the SA-155T and FL-155P speaker models. This is a direct replacement part that maintains the original frequency response and driver protection characteristics. Using this crossover with other speaker models may result in poor sound quality or driver damage.

How do I install this replacement crossover?

Installation requires basic soldering skills to connect the crossover to your speaker's input terminals and drivers. You'll need to remove the old crossover and solder the new one in its place, following the same wiring configuration. Most technicians can complete this repair in 30-45 minutes with standard audio repair tools.

Why would I need a spare crossover for my PA system?

Crossovers contain capacitors and inductors that can fail over time, especially in high-power applications or harsh touring environments. A failed crossover can send full-range signal to drivers not designed to handle it, potentially destroying expensive compression drivers. Having spare crossovers prevents costly downtime during critical performances.

What's the difference between active and passive crossovers like this one?

This passive crossover operates without external power, using the amplifier's signal to drive the frequency-splitting components. Passive crossovers are more reliable since they have fewer failure points, but they do consume some amplifier power. Active crossovers require power but offer more precise control and don't waste amplifier power.

Should I keep this crossover as a backup even if my speakers are working fine?

Yes, especially if you're a touring musician, rental company, or manage a venue sound system. Crossover failure typically happens without warning and can destroy drivers if not addressed immediately. Having a spare crossover in your crash kit costs far less than emergency repairs or replacement drivers during a show.
