    Makes sense! Good explanation, thanks.
    (Good reason to avoid front ported speakers:-)
    I could hear midrange coming out of my LS50 ports when setting them up. To be fair i was behind them at the time.
    The cabinets are very inert, so it was easier to hear.
    Doubt it would be audible from the listening position.
    Nevertheless, I placed diffusion panels behind each speaker!

      Mids should be heard through port, but they indistinguishable from sound overlall. You just hear lifeless, dull pianos, guitars and so on - that depends on the track. It should be rich of midrange, for instance Fender Rhodes electric piano (czcams.com/video/EojThBtV85M/video.html), hammond organ or rich harmonic guitar sounds like Lemongrassmusic Episode 400 - Ceylon, - try listen to them with port plugged and open. These are all examples of the magically recorded mids (i mean sound, you may not like the song itself) If you don't perceive sound of these as magical, that's the fault of your audio system:) So, in my experience, bass ports are harmful and should be always plugged.

    My old Dansk Hifi had output bas reflex at the front with an air valve closed or open and my Audience had front bas port !

    Hi Dynaudio. I have purchased some used Excite X14A active speakers. I can on some tracks hear some rattling/vibrating sounds coming out of the bass ports on both speakers. It’s only present on some tracks at medium/semi high volumes.
    Is it normal? I have everything set on “0” on the back and high pass on “flat”. Are they damaged? Everything else is sounding nice and clear - but those vibrating noises sometines are a little annoying.

    So I can move my focus 10's closer to the wall?

      Indeed. The omission of a port, and the fact that that the Focus series is active and has DSP working in its favour, makes it much more flexible in terms of positioning.
      If you're using the Dirac Live room correction as well, then there's even greater flexibility in terms of placement in a room.

      How dirac live handles especially nulls of standing waves and Speaker-Boundary Interference Response (SBIR)?

      @@tiffanytoulouse229 Even Dirac can't bend physics, although they do try 🙂 No EQ can fully compensate for a null or phase cancellation in the listening position. The Dirac algorithm uses the knowledge from several measurement points to try to "understand" if a dip is treatable or not, and avoids applying too much gain at non-treable nulls, so as to not overload the loudspeaker.

    I prefer front port

      Actually nowadays if well designed, ports can be front, back or down firing, or even on the side sometimes... but most of the buyers prefer a "Cleaner" look that doesn't show the port, that's why ports are generally on the back or down firing.

    it's like farting =)

      Uhm, yeah. Without the vibration.

    bas reflex je iba pre nízkorozpočtové audiosystémy, je to degradácia kvality len kôli zisku zopár dB na nízkych frekvenciách
