I have a few system installed. I generally go for at least 4 speakers, the sub, and the crown amp. It is always impressive. The 70V units have tap options via a screwdriver. Less labor and less speaker wire with the 70V setup.

One line I have used to convince clients to go for it ( they are not inexpensive )...

" You won't have to tell your guests how good these are... they will tell you" ! So far it has worked well pushing them over the edge. No one has ever said to me that they thought it would be better. I "always" place the speakers out from the house facing in, "never" on the house facing out. Keep the band in the back yard where they belong... not on top of your head.

I got tired of the continued warranty repair route of Rockustics, Speakercraft. I do like the "look" of a "rock" better ( even the dinosaur poop ones ), but they simply won't hold up in Florida. I sold NEAR back in the day and Terra is the continuation of that excellent product.

Honestly they seem pricey to me compared to the typical outdoor box speakers available, but the build quality is second to none. They don't exaggerate the frequency response in the specs UNLIKE most of the others and this can be a disadvantage if you get a someone comparing specs per dollar.
