If you paid $850 ... I know you don't want to hear this ... but you really could do better for one pair of tower speakers.

I think the WS Icon8 is priced at 750 before any forum discounts. The Exile SXQ9 is 900 before forum discount. Both of those will end up cheaper than the $850.

I'm not sure how much difference you will notice at the end of the line on 6.5" HLCD vs 8" coaxial but your nearfield (in boat and surf) will be much more enjoyable. It will also provide you a platform to build from if you plan on adding another pair next year. With the 6.5", you leave yourself scratching your head on how to upgrade next year.

If you are worried about wake distance, the advertised prices on the HLCD's are 1050 Wetsounds and 1100 Exile .... I'd think a forum discount would take care of 100 of the 250'ish difference.

Tough call, especially since you have purchased, but I'd consider it if it were me.
