I have 4 JBL E30s that I want to wallmount. I'd rather not drill into my speakers so I've been looking at the Vogel's VLB 200 and the BTECH BT-77. The former is a bit cheaper but accepts a maximum depth of 12" which is exactly what the E30s are. There's not much room to play there so I want to make sure it works. Any JBL owners out there wall mounting their E30s? Any other opinions on wall mounting bookshelves, either these two brands or others I may have overlooked?
