What are the separate horns going to give you that the JRX115 don't?
The 2226H is rated from 30Hz-2.5KHz- these are made for high SPL applications and they really need to be in the correct cabinet, just like any other woofer. The compression drives are a lot more sensitive than the woofers and JRX115 and the vertical dispersion is even less than the 115s- horns are made to cover a specific area as they project the sound outward- you'll be in a garage that, as you posted, isn't huge. This really isn't the best place to use horns.
