What size bolt will fit the P4’s threaded inserts?
The threaded inserts found in the P4’s will accommodate a 1/4″ -20 threaded bolt. Be careful to not overtighten the bolt as you could damage the cabinet by doing so.
Support Type: P4 Passive Speakers
Why don’t the P4 speakers have built in amplifiers similar to the A2 and A5 active systems?
The P4 came about from requests from customers that already have our powered speakers and/or have a music system and needed speakers but wanted the same Audioengine sound from a passive speaker.
Can I use the P4 passive speakers with the Audioengine S8 sub?
To use the P4 speakers with the S8 you would need an amp, like our N22, to supply power to the P4 speakers and connect to the S8.
