Can 32AT70, 42AT70 & 62AT70 sats be used on the same 70V line?

Any 70V speaker can be added to a 70V line as long as there is enough power available in the amp. However, there will be no control over the relative sound level from each speaker. In the case of the 32AT70 and 62AT70, the 62AT70 will be about 8dB louder than the 32AT70 so this needs to be considered when the sats are placed on the site.
