I'm planning to build my first open baffle sub as an experiment. I'm scoping out driver options and would like some help understanding what the likely differences are.
This will be driven with DSP equalization and a 100W class-d amp, I'll build a simple H frame enclosure. I'm only going to get 2 drivers to start with and I'll aim for flat response 30Hz~100Hz after correction.
I'm looking at two very different options at a similar price point:
GRS 12SW-4HE, 12", 12.5mm xmax, 84.5dB/W, $60

GW-1558, 15", 3.9mm xmax, 95.6dB/W, $84

Plugging them into Basta with a 70cm square baffle shows me the obvious stuff:
The 12" high excursion driver will take ~3x the power, but will play ~6dB louder at 30Hz.
The high excursion driver will kick out a load more vibration, (MMS 237g vs. 70g).
What else should I be considering here?
