Peavey 6505 Series 212-6 2x12 Guitar Speaker Cabinet

The Peavey 6505 Series 212-6 is the cabinet built to keep up with the amp that defined heavy guitar. Two Celestion Greenback 25s in an 18mm plywood box, wrapped in black tolex with white piping and a Peavey logo across the grille — it looks like it belongs under a 6505 head because it does. Fifty watts of power handling, a convertible back panel and a stereo/mono input cup make it as useful in a rehearsal room as it is on a stage.

Two Celestion Greenback 25s

The Greenback is the speaker most players picture when they think of British-voiced 12-inch drivers — chewy in the midrange, softening at the top rather than turning brittle, and quick to break up in a way that flatters high-gain playing. A pair of them handles 50 watts between them, so the speakers themselves become part of what you hear rather than sitting there politely reproducing the amp. Run a modern high-gain head into this cabinet and the aggression lands with weight instead of fizz.

Convertible open or closed back

The rear panel comes off. Closed, the 212-6 pushes a tight, focused low end that sits well in a dense mix and holds together under heavy palm muting. Open it up and the cabinet breathes — more room sound, a wider spread across the stage, and a looser bottom end that suits classic rock and blues far better than a sealed box does. It is two cabinets for the price of one, and the change takes a screwdriver and a couple of minutes.

Stereo or mono, your call

The recessed input cup on the back carries a left input and a right output with a slide switch between them. Flick it to mono and the cabinet presents a single 16-ohm load to your amp. Flick it to stereo and each speaker takes its own 8-ohm feed, which is exactly what you want for a wet/dry rig, a stereo modeller, or a pair of amps run in tandem. The jacks are recessed into the panel so nothing snags when the cabinet goes into the back of a van.

Built to be moved

18mm plywood is the reason this cabinet sounds solid and the reason it survives being loaded in and out week after week. Metal corner protectors take the knocks, a strap handle sits on top for the lift, and rubber feet keep it planted on a raked stage without walking forward every time the low E rings out. The white piping around the grille is a small thing, but it is what makes a black cabinet read as deliberate rather than plain.

Where it fits

Pair it with a 6505MH or a 6505 1992 Original and you have a matched half-stack that punches well above a 2x12's footprint. It works just as well under a modern modeller or any 16-ohm-capable head, and the 50-watt rating is honest — this is a cabinet for rehearsal rooms, clubs and miked stages rather than an arena backline. If you want the 6505 sound without the 4x12 and the hernia, this is the cabinet.
