Product information

Designed as a drop-in replacement for the C12N, the Springfield 70 is equally at home in high-powered Twin-style combos or punchy single-12” Tweeds.

It delivers tight, focused lows, clear top-end presence, and wide-open dynamics with minimal compression, the kind of speaker that wakes up an amp without altering its soul.

Players love how it brings neck pickups to life and adds clarity, punch, and articulation across the board.

It’s a perfect match for black panel and silverface amps, and a great way to add headroom and definition to vintage Tweeds that need a little more snap.

Handmade in the USA.
