TT Diffusor 12" - Standard

The original G12M of the 1960s was Celestion's first guitar speaker to use a ceramic magnet and paved the way for high power guitar amplifiers. The G12M uses a medium weight magnet to produce a sound that is smooth and warm but bright enough to hold its own against any rock backline.Known simply these days as the 'Greenback', the G12M's fabled 'brown tone' is characterised by a warm, controlled low-end, a rich, vocal mid-range and a delicate, detailed top-end. Loaded into a 4x12 and driven hard, these speakers exude warm, crunchy chords and sweet searing single-notes

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)

With the Retro 10, we set out to build something with all the qualities we enjoy about our Retro 30 in a 10” speaker. It’s got a tight bottom, an articulate top end, and a nice low-midrange growl. It can be thought of as a distant cousin of the Green Beret 10, but with more low end, slightly more top end, and a shift in midrange characteristics.

Current model from English production!

Back in 1986 a new breed of hard rock player was on the rise. To meet the demands of the players and their increasingly 'hot-rodded' amplifiers, we set out to develop a modern speaker, capable of handling much more power and overdrive. To achieve this, we coupled our 'H' magnet (the closest in performance to Alnico) with a new cone and voice coil employing contemporary materials.
Our most revealing speaker, the Vintage 30 features enormously detailed and complex overtones, a warm low-end, a famously rich vocal mid-range and a beautifully detailed top-end. Used singly to reveal the complexities in hand- wired boutique amps, or in quartets for a wonderfully intricate vintage 3D crunch, the Vintage 30 sound has been captured on thousands of recordings from a diverse range of notable players including Slash, Steve Stevens and Peter Frampton.

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.

It's hard to escape the sound of the G12H, just listen to any Hendrix recording and chances are you'll be hearing a whole raft of them powering the guitar out of the mix.

These faithful re-creations capture the unmistakeable mojo of late 60s rock guitar tones. Unsurpassed in a 4x12 for cranking out towering, huge power chords, the Heritage Series G12H (55) features the 55c/s 'bass' cone. This model is famous for its thick syrupy tones, with a deep growling back end, densely complex mid-range and a finely detailed top end.

Tube-Town's Review

The Celestion V-Type sounds like a Vintage 30 with a touch of Greenback. Does anybody really need this? We think so, because the V-type has some clear advantages over the Vintage 30.
The biggest complaint about the Vintage 30 it the strong mid peak, which is nearly linear at 100dB between 450 - 1300 Hz. The V-Type also has a mid peak, but it starts later, around 600 Hz, and drops off sharply after 1kHz, which gives it a significantly smoother, less cluttered sound.
The V-Type also weighs quite a bit less than the Vintage 30. Your back will be grateful, and combo owners will be particularly happy.
The weight reduction follows from the use of a smaller magnet. The smaller magnet has the additional advantage that it can now be used in combos in which the magnet of a Vintage 30 would come in contact with the tubes or transformers. The V-Type also handles 10 watts more, which allows greater headroom, and is particularly useful with 50-watt amps.
Finally, the V-Type is considerably less expensive than the Vintage 30, for which your wallet will thank you.
All in all, we have to ask if the Vintage 30 is even necessary any more, as the V-Type is, to our taste, a better speaker and highly recommended as a direct replacement.
 

Even and balanced from top to bottom. No sacrifice in tone for using higher power and/or higher gain with this speaker, it is crammed full of balance, definition, and most importantly, control. This speaker plays well with pedals and is slow to break up.

Building on the platform of the Blue the Gold is a higher-powered Alnico-magnet guitar speaker that recreates the unmistakable sonic signature of a ‘well played-in’ original.
Over time the high frequencies of a Blue soften and become less chalky as the cone becomes more flexible – a much sought after characteristic that the Gold exhibits straight out of the box.

Also present in the Gold sound from the outset is an added warmth and complexity in the midrange which coupled with the classic Alnico qualities of a laid-back attack rounded low end and brilliant bell-like highs deliver huge rhythm voicings and saturated vocal lead tones.
The Gold is a wonderfully expressive and revealing loudspeaker affording guitarists an unprecedented degree of dynamic control.

We recommend the GE 5751 as a replacement or upgrade for 12AX7/ECC83 tubes in the input stage of guitar amplifiers (V1 position). Whether your amp is low or high-gain, the GE 5751 provides a full, warm sound with clean bass. These tubes generate a high k2 content, making them ideal for those who prefer a rich sound.
However, the 5751 should not be used in cathode follower stages (CF) specifically designed for 12AX7/ECC83 tubes.

Superior medium-mu small signal twin triode with high transconductance. May be used instead of 12AX7/ECC83 in first gain stage of various amps for a more linear, vintage response.

• Originally designed for use in audio preamplifiers requiring low microphonics and good linearity, such as Fender "Tweed" Series
• Perfect replacement for any 6072/12AY7 type
• Relabeled Electro-Harmonix vacuum tubes are used by many OEMs in their amplifiers

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.
