I wonder how the Studio Monitors would work with Wedgie triple 8 woofers. This would keep a narrow profile.
They would work well. Unfortunately, those drivers are no longer available. However, you can do the same thing with two of the 12" drivers.
I've built both triple 8s and dual 12s. I'd much rather have the dual 12s. IMO dual 12s in H-Frame cabinets have more output than when in wedge shaped cabinets. However, these cabinets were built to fit the Wedgies and as such are only about 5" across the front. If built to fit the Studio Monitors, the wedge cabs would be 8-1/2" across the front. This would make the rear opening considerably larger and might contribute to more output.
