Description
When a cabinet in your rig starts losing punch, the Eminence Beta-12A gives you a straightforward path back to full-strength coverage. Part of Eminence’s American Standard Series, this 12″ driver is engineered as a direct swap-in for PA loudspeakers that need dependable output without a redesign. At 250W RMS and 8 Ohms, it slots into most stock PA cabinet specs, so you can refresh a blown or aging speaker and get back to soundcheck.
A 98dB sensitivity rating (1W/1M at 8 Ohms) means this driver moves air efficiently, translating amplifier power into real SPL across the room — useful when you’re chasing coverage on a budget-conscious rig or just want more headroom before things get strained. The 54Hz-5kHz frequency range covers the working band most PA cabinets are built around, giving you usable low-mid punch and clear upper-mid presence for vocals and instruments cutting through a mix.
Build quality is where the American Standard Series earns its keep on the road: every speaker in the line uses Eminence’s stamped steel chassis, a construction choice built for durability over years of load-in, load-out, and transport. At 7.5 lbs, it’s light enough to handle without adding unnecessary weight to your cabinet.
