Ohms:

Extended response on the upper range to transduce the detail of the digital effects and the harmonic content of a mic'ed guitar cabinet. Directly derived from the traditional guitar speakers, with integrated paper surround, the N12D is able to return the feel, the warmth and the character of a classic guitar amplifier, but also the treble content and the complex harmonics of the overdrive, modulation, delay and reverb effects, as well as the crisp, natural tone of an amplified acoustic guitar. The Neodymium magnet design allows a weight reduction to only 2.4kgs.

Guitarist Description
Playing a modelling amp through the PA made loading in easy but I lost the feel and control I used to have on stage with a traditional rig. The lightweight N12D gave me the best of both worlds putting the cabinet back on stage without the worry of inconsistency in my sound from venue to venue.
