Speaker cable, 2 x 6,3 mm plug, 3 m

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)

One of the most versatile speakers available in the market today.With tight and focused low end, produces crystal, clear and clean tones with sweet highs and good depth and warmth, accented by shimmering but never too brittle highs and a warm harmonic tone. Articulate, when presented with overdrive distortion notes remain well defined with lots of bite.
Very responsive, can be used in all types of music and at all levels of play. Excellent for 4 x 12 cabinets and combos, thanks to its limited weight. Excellent performer for both solid state and tube amplifiers, thanks to its modern power handling and tone balance.

The Liverpool 1275 is the classic British rock tone,inspired by tones from the 80’s. A complex, thick and vocal midrange cuts through the upper-register, while nice, full, lower-mid grunt completes the warm, gutsy, tight lows.

The G12M Greenback is perhaps the definitive vintage Celestion ceramic magnet guitar speaker. Developed in the mid-sixties, it was quickly adopted by players like Hendrix, Clapton, Beck and Page, who typified the louder and more aggressive blues rock playing styles that came to characterize that era.The G12M-65 Creamback produces the familiar woody G12M tone, but handles greater power making it ideally suited for today's amps, when a vintage tone is desired. The increased power handling brings with it low end grunt complementing the warm and vocal mid range, crunchy upper- mids and sweet, refined highs.

The Neo Creamback is every ounce a Classic Celestion, delivering all the magical tone you’d get from a traditional Creamback. The difference is, it’s built with a neodymium magnet: making this speaker around half the weight of a traditional ceramic magnet speaker.Celestion’s engineers have developed a new and innovative way to better harness the mighty forces of the neodymium magnet, enabling us to create a guitar speaker that can deliver authentic Creamback tone with ease, while preserving the benefit of neodymium’s much lighter weight.You still get the low end punch, warm, vocal midrange and sweet refined highs the Creamback is famous for: push it hard and enjoy the ‘race-car growl’ that sets pulses racing. But pick up a cab that’s loaded with Neo Creambacks and you’ll see what makes this speaker truly different.

Vintage American Ceramic Guitar Speaker
10" seamed cone speaker with a small ceramic motor, an upgrade replacement for Jensen C10R.

• Power: 15 W
• Small ceramic magnet
• sensitivity: 96,5 dB
• weight: 1,4 kg
• VC diameter: 1"

The M10C has a slightly smoother sound that retains headroom. Similar to the 10LC but with less output but a more balanced sound with more presence and sparkle on the top end.  
Initially intended for studio or home use, musicians claim it to be the closest to the original C10N from 4 and 5 decades ago.
The standard voice coil gives a more 3D presence when compared to a paper voice coil.

Originally created in the late 70s using more modern materials and techniques for a higher power handling, the G12-65 is widely regarded as one of the best speakers ever produced for use in a 4x12 cabinet.With its fast attack and tightly controlled low- end, the G12-65 had become a firm favourite with hard rock players by the early 80s. The precisely tuned mid-range and crisp defined top-end contribute to an aggressive crunch sound that punches through the mix while the mid-range warmth and detail give weight and depth to single notes.

The 10" that thinks it's a 12". This speaker was developed to recapture the legendary sound of Celestion's 1970s 10s - a 10" speaker with a surprisingly meaty tone.Low in output but with the weighty low-end balance of a 12", the G10 Greenback features a complex, creamy mid-range and smooth, vintage top-end.In small combos this speaker adds real class, and when combined in a 4x10 gives rise to a raunchy, full-bodied tone, rich in low-end thump.

Tested by Tube-Town: The Celestion 10" Greenback may not have the sonic range of its big brother - which is of course physically impossible - but it still delivers a full sound that is a bit more restrained in the highs than the 12" Greenback, making it sound rounder and softer in the highs, even with more overdrive in the sound.
All in all, the Celestion 10" Greenback is a true rock and blues speaker that we would use in open cabinets or combos to get the most out of the speaker. Do not use closed cabinets that are too small, as the speaker needs to breathe, otherwise the "British touch" that the speaker has will be lost. The 30 watt power rating also gives the speaker a bit more headroom than the 12" Greenback, making it a bit more flexible to use than the original.

The F12M-150 is a full range, LIVE response speaker, purpose designed for use with amp modellers and IRs.
Its unique design features two additional tweeter cones integrated into the main woofer cone (making it “Triple Cone”).
This enables the speaker to deliver near full-range frequency performance: from 60Hz up to 12kHz, for a rich and detailed sound, whatever your set-up.

Designed with Celestion’s Pro Audio know-how, response is flat and neutral, ensuring no unwanted colourations that could overwhelm the input signal.
But with an optimised woofer cone and lighter moving mass the F12M-150 Triple Cone is designed to closely mimic the responsiveness of a traditional guitar speaker,
delivering all the tactile feel you would expect from playing through a conventional guitar rig. It’s not just FRFR, it’s Full Range LIVE Response.

Finally, the wait is over. We have created a 10" speaker that captures all the tone and mojo of our extremely popular 12" Green Beret.   The Green Beret 10 boasts the same midrange push, articulate top end and warm, harmonically rich breakup of its larger namesake.  It also sports an impressive amount of low end for a 10" speaker.   With a 1.5" voice coil and a paper former, this speaker drips with vintage tone.    If you've been looking for classic British tone in a 10" speaker the Green Beret 10 delivers.

Tube-Town Review: Due to the smooth cone used in the 10" WGS Green Beret, its top end is much more subtle compared to the original 12" Celestion Greenback G12M, but also to the 10" Celestion Greenback. However, the midrange is not overemphasized and the whole speaker sounds full and balanced, with a distinct "American touch" to the overall sound.
We recommend the 10" Green Beret for everything from blues to rock to modern metal, but less so for blackface-typical clean sounds, for which there are better suited 10" speakers. In order for the speaker to develop its full sonic spectrum, it should be used either in an open cabinet or combo, or in a large-volume closed cabinet. A closed cabinet that is too small will dampen the speaker too much and cut the sound.
The WGS 10" Green Beret is also a real upgrade for many budget combos that are equipped with inexpensive 10" speakers and often sound a bit thin and sharp, especially when it comes to harder tones.

By applying new technologies and manufacturing methods developed during the creation of our Creamback speakers
we’ve been able to deliver a higher power rating while preserving the very essence of an alnico guitar speaker.

Delivering a glorious laid-back attack the Cream exudes warm lows and a brilliant bell-like chime.
It has smooth and organic mids further characterised by a fine-grained detail that adds a high-definition quality to the vocal range.

The Cream has been specially created to bring alnico class to all kinds of amps from 1-watt to 90-watts.
It conveys a satisfying warmth detailed expressiveness and exceptional musicality even at low power levels.
