I am not able to find the Thiele-Small parameters about the follow website:
Classic - Vintage 30 - Celestion - Guitar, Bass & Pro Audio Speakers
Who can help?

There's reason Celestion doesn't provide T-S specs - a V-30 is not a "small signal" speaker. :)

I don't have a V-30 to hand, but the WGS Retro 30 is similar. The cone weight is too much for the magnet, so they don't work very well in a TL. The Qts is too high for porting; they'll work best in a large, closed enclosure. While they're used in many smaller cabs and even open-backed combos, the V-30 is at home in a 4x12.

Really, if you want to play music rather than make music, you should be looking at 'pro audio' (PA) speakers. Guitar speakers are specifically designed to make 6 steel strings strung on a plank of wood sound musical at extremely high volumes. To say they are "colored" is an understatement.

Retro 30, measured close.

Many guitar speaker have a very low Xmax. The tradeoff for maximum effeciency against linearity.
