Keep your PA speakers running with the SACN-153 replacement crossover, the genuine Seismic Audio component that restores proper frequency separation in your sound system. When your crossover fails mid-gig, this direct replacement gets you back to full sound without speaker cabinet surgery or costly repairs.

This passive crossover splits your signal at 2.5 kHz with a 12 dB per octave slope, sending low frequencies to your woofer and highs to your compression driver. The clean frequency division maintains the tonal balance your audience expects from professional live sound reinforcement.

The 2500 Hz crossover point works across Seismic Audio's most popular PA speaker models, from compact SA-12T monitors to full-range SA-15T mains. Compatible with over 18 different Seismic Audio models including Arctic, Lava, PWS, NPS, and FL series speakers, this crossover maintains consistent performance across your entire PA system. At just 0.68 pounds, it's light enough to keep spares in your road case without adding bulk.

Perfect for touring bands, mobile DJs, and venue operators who need reliable backup components. Whether you're running sound for a 200-person wedding reception or a 500-capacity club, having replacement crossovers on hand prevents show-stopping failures. Essential for sound companies managing multiple PA systems across different events.

Installation requires basic soldering skills and speaker cabinet access. The crossover connects directly to your speaker terminals using standard hookup wire. No external power or signal cables needed.

Technical Specifications

Frequently Asked Questions

How do I know if my PA speaker crossover has failed?

Common signs include harsh, distorted highs, missing high frequencies, or a compression driver that's not working at all. You might also notice the woofer trying to reproduce high frequencies it can't handle properly, resulting in muddy, unclear vocals and cymbals.

Which Seismic Audio speakers use the SACN-153 crossover?

This crossover is compatible with 18 different Seismic Audio models including SA-12T, SA-15T, Arctic series (10", 12", 15"), Lava series (12", 15"), PWS series, NPS series, and FL series powered monitors. Check your speaker's model number on the back panel to confirm compatibility.

Can I install this crossover myself or do I need a technician?

Installation requires basic electronics skills including soldering and safe speaker cabinet disassembly. You'll need to access the internal wiring, disconnect the old crossover, and solder the new one in place. If you're not comfortable with soldering, have a qualified audio technician handle the installation.

How does a 2.5 kHz crossover point affect my sound?

The 2500 Hz crossover point places the frequency split in the upper midrange, allowing your woofer to handle vocals and most instruments while sending cymbals, vocal sibilance, and high-frequency detail to the compression driver. This creates clear vocal reproduction without harsh upper midrange.

Should I keep spare crossovers for my PA system?

Yes, especially for touring musicians and mobile sound companies. Crossovers are wear items that can fail from heat, moisture, or electrical stress. Having spares prevents show cancellations and keeps your PA system reliable for critical performances and events.
