Celestion TF1218 12" Professional Speaker 100W

I am looking at building an enclosure for 2 x Celestion TF1218 speakers for acoustic guitar amp. I am unsure whether to go with a fully enclosed cabinet or not. My main question is regarding the size of the cabinet. Is it as simple as doubling the size.  

Asked by: Marty Step
Yes, if you double the number of woofers you simply double the volume of the cabinet.
