Applying 150 to a 15" bass driver (Oris Horns)

I had a chance to do some experimenting last evening and have two options in mind but first I need some clarification so here goes.

I was able to get a pair of 150 horns from the friend of the guy that sold me speakers, he also had a router system and was able cut mounting rings. The one thing he couldn't find was the back chambers (still looking). We finally glued the horn to the ring and mounted it over the 15" Klipsch driver. There was a different sound of course, I did lose some of the articulation and noticed a decrease in volume. I fixed that by turning up the bass amp.

Does the absence of the back chamber make a big difference in the sound and volume?.

But I am having fun.

Best regards,
