Skyline LP is Low Profile. It's only 4" deep and has a bandwidth of approximately 1/2 that of the HP. The LP performance and Hemifusor performance is very close, but in my opinion the Hemifusor looks better. Thus if you need a low profile option (4") then I typically use Hemifusors.
There is one exception. Skylines perform well behind acoustically transparent fabric, Hemifusors do not. The two do function on different principles, so there is that caveat to watch out for.
