You will get more out of them that way, to be sure, but no matter how many you use the horn pathway is not going to get any longer, and a quarter wavelength is a quarter wavelength. They were an improvement in the pro-sound ranks over woofers with an F3 of 100 Hz, adequate for the needs of pro-sound in live performance up until perhaps 8 to 10 years ago, but just don't measure up to today's subs using twelve inch drivers and twelve foot pathways.
