Quick/cheap Infinity 3way update

[seantosz]

I have a friends old Infinity sm-122 3way ported party speakers. With my help we are going to add bracing and stuffing to the box while putting in new drivers and a generic crossover. The woofers are shot and the adjustable crossover is silly and crapped out anyways. Considering these low buck to begin with we plan on just replacing the drivers and crossovers in a similar low buck fashion. I think putting in some new dayton drivers will yield a nice increase in performance.

I decided on the following shopping list to pop into the existing cabinet.

https://www.parts-express.com/dayton-audio-dc28f-8-1-1-8-silk-dome-tweeter--275-070
https://www.parts-express.com/parts-express-speaker-crossover-3-way-8-ohm-800-5000-hz-100w--260-210

From what I read some simple L pads are needed to match the sensitivity of drivers. They are all 8ohm.
woof 90.5dB@ 1w/m
mid 85.5dB@ 2.83V/m
tweet 89dB@ 1w/m

Should I just adjust the woof and tweet down to the level of the mid? Am I missing any baffle step loss considerations(they will be placed against the wall)? Are there any other simple and cheap considerations that I am missing?

NO for woofer and YES for tweeter.
