How usable are JBL 1210 as an isobaric subwoofer ?

[Tangband]

I would like to know if someone have used this 12 inch driver for subwoofers at home ?

Having big respect for JBL and what they used to be, I was thinking that maybe 2 of this driver would be nice for an isobaric solution ( clamshell) in a closed box about 40 liters and with Linkwitz transformer . It would easily reach 20 Hz.

Is this a less good idea ? Maybe its much better to go with only one peerless xls 10 in a 40 liters closed box ? The price
is the same .

Why isobaric? It only halves the VAS, otherwise does very little. Just expose both woofers and use some DSP to flatten response. It will go louder, perceivable deeper and have better power handling.

Woofer wise, I would not expect much. It’s a cheap car sub. The fact that the JBL “spec sheet” does not contain any TS parameters should be enough of a warning…

Thanks for the reply. Youre probably right .
