If you mean that it would simply take away anything lower, it doesn't, it would actually roll it off faster.
If you mean that you can modify the response in special ways to increase your bass, you can.
did you make the speaker using the racetrack drivers. Very keen to knowmore and how they came out. Please share build
Some familial embuggerance has halted proceedings but i'll be back on it in January. I can't wait but I'll have to 😉
I have a gap between woofer magnets of about 5-8mm
Dave, if I may ask? What material do you place between the woofer magnets? Is it something solid like timber dowel or something that gives slightly like compressed felt?

Dowel is very hard to fit. One of the first things we tried.
We usually space things so we have sufficient room to have the holey brace (plywood) support the magmets.
Given you are too close for that i would glue, one by one, a pile of something solid on one of th emagnets until such time as you have just the right thickness. My first thot was veneer, NAIM used metal washers.

Thanks for the info Gents. I think I'll try washers or maybe pennies
I'm using long (70mm) Allen head bolts to retain the bass drivers. Opposing bolts will screw into a threaded hex rod to allow me to add camping force to the drivers/box.

Hi JRKO,
I was considering doing a very similar build using the same drivers. My plans were confirmed when the wife saw the 5x8 racetrack drivers and said, "Oh those look cool!" So I am apparently now committed to using them. However, I think she wants them facing forward vertically for skinny speakers. I don't think that will affect the sound as long as the crossover is low enough.
I also wanted to try another passive crossover as well. Have you settled on a crossover design? I was was quickly playing around with the curves and it looked like a simple first order with two woofers and a single Alpair 5.3 modeled well. Very curious to what you were thinking.

First, woofers on the side has a real purpose, skinny box and push-push woofers for reactive energy active cancelation.. Aaron did a passive XO for these that works well.
Different drivers means different XO.

My apologies if I wasn't clear; I do want to use the same drivers as the OP (Alpair 5.3 and 2x sb15sfcr39-8 5x8).
I realize that the side woofers helps to cancel out the lateral forces, but I predict that she wants to see the drivers on the front. Would that significantly affect the crossover design? For that matter, what crossover are you referring to that Aaron designed?
