Correct Floridapoolboy. They need to be crossed over. What is happening is that the horn is very efficient and can play louder much easier where the woofer can not for full range duty. Once you cross them over the woofer becomes much more efficient as well. You do not want to put the horn right at ear level. Try having the horn shoot over your head, not at your ears. The speakers are very powerful. If you told me from the beginning that you were going to run them full range I would have said no way, don't bother. I don't even run my 3622N's full range. Run the rockets full range and then run the jbl's small with an 80 crossover into your subs to compare. What subs are you using? If they are very good for music then you will get a better understanding. Also, pro drivers are very stiff and need break in so that 10 inch is still breaking in but still won't be able to do full range when broken in. The reason I want you to do this is for other people to. There are 2 many comparisons on here(especially subs) with not exact or proper placement for optimal use for both sets of subs or speakers which does not create an equal playing field. Remember what you are doing, comparing inexpensive surround speakers in 2 channel (full range) against more expensive (made for full range and 2 channel) speakers. This test is not favorable towards the JBL. Switch it around. Put in some movies, run them on small with 80 hz crossover and place the jbls up higher facing above your head, not at your ears. I bet the results will be different. I crossed mine over to my sub system which makes them sound full range. Big difference.
