Default JBL L300 DIY for Newbies

Recently I decided to build my L300 clone project, that's not the first attempt, some time ago I build one with a 2215 woofer and couple of scan speak drivers (8545 mid and 6600 illuminator tweeter) but the result as not as expected.

Now I have bought some good drivers, the JBL 2420 mid with 2307 horns and the 2405 tweeter, and the Nelson PASS components for the crossover at Madisound,

I was wondering about the 2215 woofer, it's a LE15A professional version with 8 ohms, do I have a lot to expect if changing to a 2235H?

There is a pair at ebay for selling from a guy from Hungary, but it does not seems very in good shape compared to the other components, also the cones are different.

The speakers are with a hole in the bottom, this I made to increase de cubic feet required for the 2115, but I pretend to remove the hole inserting a 1 inch base of MDF,

They were also used without passiver crossover, I used a DCS2496 with 6 mono amps.

I will made the bracement as the originais, 2 in each panel horizontally and 2 at the rear panel vertically, with 1 x 2 1/2 inch woods, like this I saw at audioheritage forum

The question is should I consider buying these 2235? The 2215 doeas not do the job?

Also I would like to hear some tips and opinions about this project.

The base I will remove and let them with the L300 original size.
