TT Diffusor 12" - Standard

The ET10 is the 10” version of one of our most popular speakers: the ET65. The ET10 boasts a tone reminiscent of its 12” counterpart, but with a bit more of a pronounced midrange. The low end from this 10 is surprisingly heady, but remains tight in all situations. Top it off with a smooth but articulate top end, and you have one of the most highly anticipated ten inch speakers to date.

Celestion ‘Blackbacks’ are well known as 1970s variations of Greenback speakers. The reason for the change in can colour is lost in the mists of time, but arguably the most celebrated Blackback of all is T1511: the G12M with 55Hz bass cone.

Inextricably linked with players such as Free’s Paul Kossoff, whose famously sweet sustain lasted for miles, T1511 is the very essence of Celestion tone; bringing together punch, sparkle and a midrange you just might not be able to live without.

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.

The 12” Veteran 30™ speaker from WGS is tonally superior to Celestion's™ Vintage 30™ speaker. The tonal improvement is in the upper-mids. The Veteran 30™ speaker has smoothed out the upper-mid "spike" notorious in the Vintage 30™ speaker.

Create your next signature sound with the Boston 10” guitar speaker. Spotlight your tone with a driver that delivers a warm, articulate bottom-end, scooped mids, and blooming highs.

This model includes a good old fashioned 1960’s style Alnico magnet assembly for an ultra-quick impulse response. The often-misunderstood magic of Alnico is that it partially and temporarily demagnetizes when you push them hard, applying a simple compression effect that adds a satisfying sense of sweetness that can't be beat.

Celestion ‘Blackbacks’ are well known as 1970s variations of Greenback speakers. The reason for the change in can colour is lost in the mists of time, but arguably the most celebrated Blackback of all is T1511: the G12M with 55Hz bass cone.

Inextricably linked with players such as Free’s Paul Kossoff, whose famously sweet sustain lasted for miles, T1511 is the very essence of Celestion tone; bringing together punch, sparkle and a midrange you just might not be able to live without.

Combining a hemp cone specifically chosen for its tonal character and a medium-weight ceramic magnet, the G12M-50 Hempback represents an exciting new development in Celestion’s never-ending pursuit of outstanding tone. Distinctive and well-defined, the Hempback delivers a balanced low end, plenty of mid-band character together with smooth, silky highs.
Targeted for use in American voiced amps, for example in combos such as a Deluxe Reverb® or Blues Jr.®, to deliver true American-flavoured tone and cleans that are second to none. Load up a Hempback for a sweet and smoky sound that’s musical and responsive, and let your hemp tone shine through.

Tube-Town's Quick-Test (as of Feb 2023):
Speakers with hemp cone have been around for years, but somehow they never really caught on. To our European ears they usually sound a bit muffled, sometimes even dull and also a bit lifeless, which is why the expectations for the Celestion Hempback were not particularly high, but the surprise was then all the greater.
The Hempack was tested in an open 112 REX powered by a TT JC18. The guitar used was a Tele with hot pickups. In this configuration, the speaker delivered wide and balanced sound right out of the box, no overemphasis or annoying frequencies.
The bass was clear, the Tele's low strings came through strong yet defined, the mids were round but not overbearing, and the highs were convincing with a pleasant yet restrained presence. And even at gain setting 10 there was no cause for complaint (as long as you didn't turn the treble control on the amp too far to the right). The sound was round and without sawing highs, but still had its own character and enough bite to assert itself in a band context.

Conclusion: In the environment specified by Celestion (open cabinet or combo), the Hempback can convince with a balanced sound image, and that with both clean and heavier sounds. It is fun to play it. The 50 watts of the speaker are perfectly sufficient for a variety of amplifiers and a sensitivity of 99 dB is not exactly little either, and the weight of 3.5 kg makes itself felt positively especially with combos, especially if you have to move them often.
So all in all: thumbs up.

10" seamed ribbed cone with Large Ceramic Magnet, the replacement for C10N, paper voice coil.
Similar to the 10LC but with less output but a more balanced sound, with more sparkle on the top end. A slightly smoother sound that retains headroom.
Originally intended for studio or home use, many musicians claim it to be the closest to the original C10N from 4 and 5 decades ago.  
Paper voice coil versions are most similar to the originals and impart a woody tone that is flatter when directly compared to our standard coil.

This version is only suitable for loudspeakers which are frontmounted

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.
