Hi Wdk:
None of our current Rock Speakers come with an internal 70V Transformer. But we do have an outdoor direct burial external 70Volt transformer so you can convert any of our Rock Speakers to 70V. It is our model OSD EW70Volt. You will need one for each speaker. There is also a couple of garden speakers that feature an optional outdoor mounting kit. Check out the FARZA-5 and FARZA-6 Pendant/Landscape speaker. Both Speakers and outdoor garden mounting kit sold as pairs. Both speakers have a built-in 70V transformer. They are a new product listed as out of stock. They are due at the end of April.
Good luck
