Ahh.. so you just want plain aluminum..
You need to see the entire speaker first before deciding to spend the extra cash on it, in my opinion. I have a lot of aluminum in my room - considering it is very contemporary - but seeing the aluminum trim on the Summits (clear, plain aluminum) made me realize that it didnt look good and wouldnt look good even in my highly contemporary setup.
My advice, once again, is you need to see this trim option in real life. If you like it, then go for it.
I just dont want you to regret it.
FYI, I really really loved the regular aluminum trim - I thought it would go well with my setup. But seeing it in person kind of took me back, didnt like it no more.
