One of the first sets of speakers I picked up when I got into this hobby around 8 years ago was a set of the sp-z8's. Loud and very efficient. They had massive 17" woofers as I recall and too many other drivers to count! I thought the z8's sounded good until I got a set of KLH Model 6's which I was quick to recap and re-dope the cloth surrounds on. After that the Z8's went into hibernation and eventually were gifted to the teen age son of a friend. So back to the ops original question, it's gonna depend on what you're using them for. Party and loud, perfect. Otherwise, keep looking. My question to the op (who resides in Chile) Is there much choice in selection of quality speakers there? If not, the Z's would still be a viable option.
