I love JL Audio, it's really all I run because they sound so good and last so well but the TR's are a bit disappointing. I tried the TR's in the back of my truck and ended up blowing a tweeter while the XR's in the front are still going strong.
The TR's come with a 3/4" tweeter while the XR's come with a 1" tweeter, the difference is huge! The XR's are the way to go if you use JL, not only for clearer sound but , even more important on a boat, for more volume without distortion.
Sorry I am not more usefull with the other choices but I am not as familiar with them. I do know, however, if you step up your budget a bit and get the JL Audio XR components, you will thank me later.
