Your dealer is correct. Very little output, at the port's resonant freq, if you're crossed over at 95Hz/4th order. If you block the port; you may be robbing yourself of some driver speed and efficiency.
Plugging ported speakers and active Xovers
I have recently gotten a JL Audio CR 1 2 way active sub crossover and am wondering about some set up questions regarding the ports in my main speakers (Bryston Mini T's).
I did a lot of reading and was advised by JL to plug the ports in my speakers for better phase/time alignment between sats and subs and enjoyed the resulting tightening/impact/articulation.
My dealer advised that it may not be neccessary as when utilizing a high enough crossover - currently crossed over to stereo subs at 95hz (LR 24db slope) - the port is a non issue as the speaker wouldn't be producing any (real) output at its port tuned frequency, and ported drivers are not sealed drivers i.e. they usually have differently designed motors and a ported driver could be harmed by plugged/sealed operation.
I like the sound I'm getting (love it) but want to be sure I am not damaging the drivers. I am going to try without plugs to see the difference but was hoping for some input. I am also reaching out to the manufacturer. Any input is welcome!!
