From Celestion:
Sacrificing none of the delicious musicality of your favourite Celestions, the Neo 250 Copperback is a neodymium speaker that supplies tons of tone without the signature cone break-up immediately associated with the classic Celestion growl.
It's definitely not the brown sound, but for those wanting more transparency and less midrange vocal intensity the Neo 250 reveals the best from your amplifier and playing without additional colouration. The speaker's unique response has a tight low end, neutral low mids, a clear, open upper-mid definition and well-controlled high treble, meaning you can shift from shimmering tubular-bell-like cleans to flute-like high gain with simply a tweak of the drive knob. Rated at a monstrous 250-watts, the Neo 250 works together with your amp to provide unparalleled dynamics, delivering all the headroom and touch sensitivity you could possibly need. And built with a neodymium magnet, you get all this power and tone weighing in at a modest 5.5lb (2.6kg).
