Recently got two Dayton Audio DC160s, after doing some research decided on building the Classix II by Paul Carmody. problem is he uses the unshielded version of the DC160.
Is there anything I have to take into consideration for using the shielded version of the driver? maybe increase the volume of the enclosure a little bit?

DC160s and Classix II
Hello from Melbourne
I've done an Xsim comparison of the factory provided zma and frd files, they're virtually identical (att). The crossover can therefore be the same.
In terms of other official specs, they're pretty much within 10% or less variation, excepting VAS (equivalent volume) which is 22 litres for the shielded and 18 for the un-shielded; and the Fs (resonant frequency) which is 0.30 Hz for the shielded and 34 Hz for the un-shielded.
Someone who knows how to interpret these figures could better advise you, but I think you'll be OK with the same cabinet dimensions.

Hello again Geoff!
Thank you so much for the comparison, I did not know that there would be any difference even if that little to shielded versions. Interesting.
I had a look at Paul's website, he doesn't say anything about that issue for those speakers.
Edit Edit! The FS for the shielded is of course 30 Hz, not 0.3 Hz!
See what other replies you get, if you had to increase the volume a little I'd just make the cabinet very slightly deeper: the baffle dimensions should stay the same.
