They are a great concept, looks from the side is not bad but from the rear they flare out a bit much.
If I had the shop, garage I might have tried something simular, but then I found some HMF highmount
carbons off the forums for 600 bucks and never looked back.
If you could go shorter cans and keep them tucked closer to the swing near the rear they's look really mean, sound great though!
