I am thinking of building 2 Full Marty subs. I was hoping to get others opinions on these or others that GSG offers. Link (GSG Audio). I was looking at the comparison table that they offer. My original plan was to use the Ultimax 18-22. This only rates as average quality sound output, but has the highest spl. I am thinking that a 4 ohm load is best for my amp. Crown XLi3500. Most of the other recommended drivers are 8 ohm. Looking at Parts Express I found the B&C TBW100-4. This is a 4 ohm version of 1 of the drivers they recommend going by the part # of the driver. Many of the specs are different between the 2. Another thought I had was to run 2 of the PA460 isobaric if possible. This will put the back of 1 driver outside of the box. I can wire it in parallel to get the 4 ohms. This is an expensive DIY project. I would like to keep the driver cost down, however I don't want to compromise the sound quality. I would appreciate any info on this or anything else related.
