Definitely a Monitor 7, pic 4 shows the model number, with the remaining digits being the serial number.

Looking at picture #4, that '7' on the plate might indicate that it is a Monitor 7. It is separate from the other numbers. Dan

Looks like the model five. The tweeter looks like the 2ooo version. These speakers were available in the mid to late 1980's. I had a pair of RTA 11t towers with similar drivers back in 1987.
