Re: Dual Eminence LAB12 Ported/Sealed

My face melted when I saw the craftsmanship of these. So awesome...Mine looks like Homer Simpson built it, but it was fun and I learned a lot about what not to do next time. I built a sealed, next I am building a ported to see the difference when using the same driver.

Re: Dual Eminence LAB12 Ported/Sealed

Build it and be happy many people have been pleased with the LAB 12 in sealed cabinets but it will suffer from much less output below 30Hz. More accurate thou.

I would never go less than two sealed 12"... two vented 12" cabs can get quite far in a small to medium sized room for HT.

I have only found these

Eminence are Klippel customers that is all I know from google.

Re: Dual Eminence LAB12 Ported/Sealed

Just go creative with a CAD software and find a buddy with a CNC

I never accounted for the lost volume with the big vents but they turned out well either way. Lining the walls adds some extra volume seen by the driver.

Buy a measurement equipment there are well known kits for decent money that are simple to use and very useful when getting the tuning right.
Software like WinISD will ball park it quite good but a lot of things can go side ways with real cabinet volume, vent diameter, lengths and lining.

Eminence also share some recommendations in the pdf above that would be the safest simplest choice, large vented.
