Bought a pair of 8T 11027 which I believe is RTA 8? Got some info from another thread. Wanted to know how much these sold for new? I got these at a garage sale for $10 a piece they are in excellent condition and saw little usage. They are replacing a similar aged pair of In*?%*ti these are much more impressive especially for not having a midrange!
The speaker uses a single 1" dome tweeter and two 6.5" drivers. The frequency response is from 30 Hz to 25 kHz with the -3dB limits of 42 Hz to 23 kHz power handling is 250 watts/channel the impedance is compatible with 8 ohm outputs and the efficiency is 89 dB. They were produced from 1987 until 1990.
