Celestion "Vintage 30" - Thiele Small Parameters wanted
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.
according the URL
the WGS Retro 30 has follow parameters:
Resonant Frequency (Fs) 98 Hz

Very high Oms indicates also good results for a high pass filtered satellite vented boom box for top class home audio between 80 and 5000 Hz together with a tweeter from one of the models about
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.
