Share Speakers are extremely important when we are talking about tone. So, what should I get to achieve the tone I want? This article will be a maybe not so small post about the history of Celestion, as well as a brief description of each model they produced over the years.
Since , all Celestion chassis drivers have been stamped with a date code (2 numbers and 2 letters), denoting the exact date of manufacture. The codes are added on the production line and are placed on the speaker’s housing leg or the magnet edge.

Worn or mismatched speakers in wattage or impedance ohms are one thing, but different speaker designs also provide dramatic changes in tone and response for guitarists. And this is an area that is all too often neglected.
Ask many guitarists, “What speakers do you use? Many of our reader questions become the basis of new articles written and this is certainly an example of one of those. These topic areas can be discussed in simple terms or they can be more scientific when one chooses to dig deeper.

August 1, Bose original series I and series II are nearly identical. The speaker enclosures are all wood, are sealed acoustic suspension types, have all straight surfaces, and came with a beige grillcloth. Series II had a small silver “BOSE” logo fixed to the front lower right corner of each cabinet but if you replaced the cloth grillcloth with the walnut trim, they would look identical.
The drivers and cabintes of I and II are also identical, the only difference I am aware of is that the segregation of drivers supplied by CTS into three groups of matching units was done by computer. The series II equalizer is also slightly different having more high frequency boost curves and fewer cut curves series one only had 2 boost curves and 7 cut curves, plus one indicated as flat.
In general the series I and II have held up remarkably well with no signs of deterioration in my series I after 35 years of ownership. Starting with series III, the design changed radically. The system became a ported design, Bose manufactured the drivers themselves using foam surrounds which did have a much greater tendency to rot and crumble, and the working enclosure is made from an injection molded plastic. You can identify it by two small pipes projecting through the rear grill cloth.
The ported design is more efficient than the original but with a loss of almost a full octave of bass.

That amp worked pretty well with my Rick string. That amp turned out to be an early-production Pro-Amp. I started to investigate the world of pre-CBS Fender amplifiers. During that era Fender blackface amps, covered in black tolex with silver grilles, were everywhere. I combed through vintage dealer ads and began to pick up Fender amps in tweed, white, brown and blackface versions, trying to stick to or before. Some of the amps in my collection have their original tubes, capacitors and speakers; on some they have been replaced.
How can I tell how old my speaker is? We attach a small label to either the side of the magnet or on the inside arm of the basket with our spec number and manufacturing/date code on it. The spec number will begin with the size of the speaker (i.e. for a 10″ it would be ).
You may compare these with your own speakers to determine what you have. Speakers are like ice cream; we all have our favorite taste. Some like strawberry while others like chocolate. What someone finds harsh can be beautiful sparkle to others. Speakers can have different frequency response depending on materials and construction design, like cone shape, magnet weight and coil size.
New speakers will therefore sound different from vintage speakers. There are of course exceptions to our preference of American speakers. One is a heavily cranked amp with a bright single coil guitar. The amp has a huge bottom end and a slightly edgy Fender 6L6 push-pull class AB cranked tone. Think of Keith Richards. Another example is a bright jazzmaster with bridge and neck pickup combined for some jangly surf tone, through a big clean amp like a Pro Reverb, Super Reverb or Twin Reverb with lots of reverb.
