blue gold
http://www.tdpri.com/forum/amp-central-station/241175-celestion-blue-vs-gold.html
Both speakers are basically identical. Same cone, same voice coil and suspension. However, the gold is held together with modern glues that can withstand higher temperatures internally without falling apart. Also, the insulation on the voice coil wire has similar higher temperature treatments that enable the extra power handling.
Otherwise both are the same. Any sample speaker from a batch of 100 of the same design will sound slightly different. Making speakers IS NOT an exact science. As with any electromechanical device, performance can be expected, at best, to be 'ball park'.
Incidently, two speakers handling 30 watts will sound dynamically different to one speaker handling the same power. This is because the cone has a non-lineal movement forward and back due the the increasing opposite forces applied by the cone's suspention components. Therefore, some degree of compression should be expected with clean sounds. This is why 4 x 12" cabs can sound a lot more dynamic when playing clean tones. Not so important for distortion sounds, as they are already compressed by the amp.
Well, no I've not heard that, but magnets are just magnets... they don't have a sound. But magnet strength does make the speaker sound different. High powered magnets make the bass a lot more tight and the mids more dominent. This is why speakers with small voice coils and weak magnets have a 'smiley face' output response. And why big 15" speakers with small voice coils and weak magnets (cheap) sound farty and cannot damp the cone very well in the bass frequencies. This is the reason the old blues guys liked those inefficient 15" speakers... for that grumbly bottom end distortion tone. The Peavey 'Blues Delta' is based on those old amps. But they're generally not very loud due to the cheap magnets fitted.
Speakers 'break up' by introducing harmonics NOT made by the amplifier itself. They do not create distortion in the sense that guitarist think they do. The speaker is 'excited' by the amp, but do their own thing by allowing the cone to resonate at different spot frequencies and add electromechanically generated tones off the cone.
Speakers contribute far more of the 'tone' you hear than tubes or anything else does. The speaker and output transformer are probably the most important two component in your amp. Although, the output transformer's high output impedance (about 4 ohms usually) can be simulated in SS amps quite easily and accurately (Marshall's 'Frequency Dependant Damping... but everyone's using that idea now!). Speakers decide the final tone you hear... not the tubes. They all break up differently when pushed... some can be pretty exyteme. Tubes are well over credited for the 'tone'.
Speakers are very misunderstood by most guitarists. They think they are mostly the same, although can really transform your amp into another world of tone. Choose speakers carefully, but you may need to spend a small fortune before you find the one for you.
As a designer myself, I have a stock of different speakers which I know make certain classic tones. This knowledge has taken me many years to learn!
