I am now using a pair of 2402's (one on each side). I love the highs I get if I am in the "sweet spot" but my "rock room" is very large (20' x 45') and I need more coverage than I am getting from the 2402's, but I don't want to give up what I have now.

What should I expect if I add a pair of 2405 slots along side of the 2402's?
Will there be problems?:blink:

Has anyone tried this or maybe shed some thoughts here?

Thanks
David

Will there be problems?:blink: Yes, they will interfere with each other, called "Combing." Use just the slots. They only beam in the vertical. Compare beamwidth vs. frequency curves for the two drivers:

If you want "coverage," use 2404:

Or 2406/7 on the constant directivity waveguide of your choice....

The 2405 can sound very nice but you want to cross them over as high as you can say 8-10K. They are very beamy in the vertical axis so you need to set them up at your seated height in an Music/HT set-up. The 2404 will definately give you more coverage. Can you tell us what other componenets you have with them??

Rob,

Thanks for your comments.

For the R & L fronts I am 4-way crossing over the following with an Ashly XR-4001;

JBL 2402's (4500hz and up)
Rinkus Heinz CD-3302 (2" throat mid horn) (1500hz - 4500hz)
EV EVM 12L Pro line (12" mid) (300hz - 1500hz)
JBL 3678 bottom (2226H 15") (100hz - 300hz)

Hope this info help, any suggestions please.
Thanks again
David
