I just wondered if Rob G had the gap length and VC length to hand of these transducers. I know it came up on the old forum but has been lost in the either.

Just finding out how dodgy my recones were. I take it the coil should be midway down the gap? Those dodgy reconers said they sometimes modify these with a overhung coil design, this sounds crazy to me. Totally weak BL would be the result of this surely?

I wondered if there should be a advanced driver spec section on the site with as much detail as possible on the popular models. Giving a bit info than the sales spec. The older specs are a bit vague. Perhaps enclosure volumes used etc. Plus of course a note on that ever popular impedance issue question!

I hope these advanced specs won't be lost in the future. One day JBL drivers might do a 'altec' and stop producing drivers and junk the tooling.

Thanks

Dave

PS this should be in 'technical' sorry.
