So the other day I glued up a couple PE flat packs, and then dove into the stash to see what I could put together cheap and effective.
I modeled several 6.5" class drivers in the tower, and surprisingly the generic Kevlar driver I demo'd at IowaDIY in 2019 modeled the best. Other candidates were the Dynavox 6.5" honeycomb, the Max Fidelity 6.5", and a Rival.
This will be a 3-way, midrange will be the cheap HiVi 2" dome, tweeter will be that Dayton waveguide thing. The woofer and tweeter used to live together in the design I brought to Iowa.
Here is what I mean about how it models, most alignment details are in the screenshots:
Modeled excursion at 10 watts:
Modeled SPL at 10 watts:
Modeled vent velocity at 10 watts:
I will machine the baffles today, and finish the glue up.
So the purpose of this design, in addition to getting rid of shit, is to gift these to a couple we are friends with.
Here is what a slight EBS looks like:
I beat the living shit out of these cheap woofers, and was impressed with how much of a asskicking they could take. I have no compunction about driving them down that low.
Should be a fun, quick, and relatively straightforward project to get done.
