We did the 'after purchase' addition of a tower with our 2011 H200. I think we paid close to $4k for ours but it was a pretty involved setup. The dealer sourced the tower from Four Winns - I believe it was manufactured by XTP (who maybe is now owned by Monster Towers).
I prefer this tower compared to what Four Winns offered as OEM on similar '10-'11 boats as it doesn't have the added tubing of 'side rails' and then a tower mounted on top. Also, the version they sourced for us has lighting built in for both a top light and rear facing lights. We opted for tower speakers and the dealer sourced Wet Sounds Pro 60's matched with a cheap Jenson 760 4 channel power amp. That combo performs well - both tubers and boarders (and some fellow cottagers
) can hear tunes no problem.Lastly, the biggest concern my wife had was that our factory bimini still worked with the tower. Our dealer was sure that it would but once the tower was installed...no go. To remedy the situation (they are pretty awesome with their customers), a fixed hard frame bimini option was installed and I have to admit, I like it quite a bit. No worries at speed, rarely ever take it off, only concern is that if you do want it off you have to store it somewhere...and not on the boat. We leave it on the dock if we take it off.
The dealer had told us that it a tower was something we wanted, it was MUCH cheaper to buy it factory installed. All they had on the lot were wild red frenzy editions and we were stuck on the nice looking black so we went without for a season and paid more later.
