## Description

The Eminence Professional Sigma Pro 18A-2 - 18 inch Bass Speaker was designed to provide punch and clarity often lacking in 18 inch speakers. This great woofer from Eminence is recommended for professional audio as a subwoofer in vented enclosures.

Review: Quick Fix for Alto Subwoofers - The OEM units had failed, so I tried these as a substitute. Worked well, are lasting through several outdoor events. No issues!
Review: Great Replacement - Used this to replace an Eminence sub in my Ampeg SVT 18 cabinet. Works awesome!!! I did drop the wattage and went to the 8 Ohm compared to the original speaker, just because that's what the Combo Amp output recommends. Sounds Great, has awesome lows, and Is plenty loud for a medium sized audience.

## Questions & Answers

**Q: Replacement for cerwinvega 189je ii woofers from my l-36 cabinets? these are the 36"x24"x36" folded horn cabinets, would these sigma pro 18a-2 work?**
A: The Sigma Pro is ok for a horn, but the cone is really soft. The Kappa Pro 18LF-8 or the Omega Pro-18A are better choices.  Thanks- Jay - Loudspeakers Plus

**Q: The description says 650 watt music program. the manufacturer says that 650w continuous, 1300w program rating? which is it?**
A: It can handle 650w Continuous and 1300w programmed (max)

**Q: i'm throwing 750 watts bridged amp but it's still pops when i reach to clip version.what gives?**
A: Hello, this driver is rated at 650 watts RMS so if you are sending it 750 watts and a clipped signal that is the reason it is popping. I would recommend turning the gain down some to avoid causing damage to these drivers.

**Q: Would the sigma pro 18 -2 be suitable for a martin wsx 18 type enclosure and would the enclosure/port length require modification?thanks so much chris**
A: PRobably not - you need either Definimax 4018LF or Faital PRO 18XL1800.
