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.

The Invader 50 is the weeter and creamier version of the hugely popular Green Beret.  It retains all the same great rock and roll character with just a little sweeter top end and breakup.  The beefed up coil means you can now use it with higher wattage amps.  It's time to invade your amp with tone!

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.

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.
 

Universal size for 12" speakers
Dome diameter: 120 mm - recommended for guitar loudspeaker with massive beaming and higain sounds

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.
