[QUOTE="Visor57, post: 54429, member: 759"] @Ian: On the subject of the JBL driver, have you tried it in an isobarik vented configuration before? The WinISD simulations look promising, although I'm not certain about the excursion plot at 50W (it looks like yours at 200W!). Attached are a few graphs (I kept them high res, hope that's not a problem)... Green trace is vented (same volume and tuning as before), Blue is vented isobarik, Yellow is sealed and Orange is sealed isobarik. Note the longer vent required which is typical of vented isobariks.
