About this listing
When your sub driver gives up the ghost mid-gig, you need a replacement that actually works — not some weak excuse that barely moves air. The San Andreas 18" driver brings legitimate low-end punch with 500W RMS handling and extension down to 35Hz. This isn't a budget driver pretending to be pro gear; it's built for the reality of weekend warriors and working sound companies who need their subs to actually shake the room.
The 4" voice coil and 120 oz magnet give you the thermal capacity to push hard without cooking the driver during those three-set bar gigs. The die-cast aluminum frame dissipates heat properly and mounts solid — no flex when you're really driving it. Paper cone with cloth surround gives you natural bass response without the brittle breakup you get from cheaper drivers trying too hard to sound modern.
At 8 ohms and 100 dB sensitivity, this driver plays nice with most amplifiers without demanding exotic impedance matching or massive power to get loud. Whether you're building custom subs for your band's PA or replacing a blown driver in existing cabinets, the mounting dimensions and power specs work with standard 18" sub designs.
This is a raw driver — you still need to build or modify an enclosure with proper internal volume and port tuning. No cabinet, no crossover, no mounting hardware included. Just the driver.
Bottom line: If you need an 18" sub driver that handles real power and extends low enough for modern music without breaking the bank, this San Andreas delivers the goods.

Frequently Asked Questions
What size cabinet do I need for this driver?
This driver works best in ported enclosures between 4-8 cubic feet internal volume, tuned around 35-45Hz depending on whether you want maximum output or extended low end. Bandpass designs can work too but require more precise calculations. Don't just throw it in any old box — improper enclosure tuning will kill your bass response and potentially damage the driver.
Can this replace the blown driver in my existing sub cabinet?
If your current cabinet uses an 18" driver with similar specs, probably yes. But check the internal volume and port tuning first — just because it physically fits doesn't mean it'll sound right. Measure your old driver's mounting diameter and make sure you have enough depth clearance. When in doubt, stick with the same brand and model you had before.
How much amplifier power should I run with this?
Pair it with 400-600W RMS at 8 ohms. Having slightly more amp power than driver rating gives you better headroom and cleaner sound when you push it. Make sure your amp can handle 8-ohm loads and has proper filtering — raw drivers like this need external crossovers to keep subsonic garbage from destroying them.
How does this compare to 15" subs for bass extension?
The 18" format gives you real extension down to 35Hz versus the 40-45Hz most 15" drivers manage. More importantly, that larger cone area moves more air, so you get higher SPL in the low frequencies. If you're doing electronic music, hip-hop, or anything with serious low end, you'll hear the difference.
