I have someone that wants to put tower speakers on an MC but dont know what diameter the tower is? Any help?

I know the X-Star is 2 7/8. Not sure about any others.

depends on the boat.

Here at H2O Pro Accessories were sportin a 2007 X-2. The tower is a 2 1/2" tower. <BR> <BR>You can always call mastercraft and ask for customer service. They will have no problem telling you.

Your dealer should know. I am pretty sure the X-star is different than any other MC. The rest are 2.5 inches. <BR> <BR> <BR>Or you can have him get a cloth tape measure, take the circumference and divide by Pi (3.14) I think that is right...circumference = 2piR, right? The diameter is 2 X the radius... <BR> <BR>Jonny, How are you?

Jonny, <BR>Like Bruce said it all depends on the boat. If you give me a shout what boat you are looking to put them on I can get you the tower Diameter. <BR>Let me know, <BR> <BR>John <BR><a href="mailto:john@waterskis.com">john@waterskis.co m</a> <BR><a href="http://www.waterskis.com" target="_blank">www.waterskis.com</a>
