Dougal Posted October 19, 2017 Share Posted October 19, 2017 Just bought a new pair of Q-Acoustic speakers. In the box are a couple of soft foam plugs, that I assume are for plugging the rear vents. What exactly should this achieve? Link to comment
mourip Posted October 19, 2017 Share Posted October 19, 2017 My Omega Audio ported speakers have those also. Mine are large "nerf" balls. They are basically for tuning the speakers. In my case they restricted dynamics some and muddied the sound so I do not use them. On my previous pair they helped. Probably depends a bit on your room and placement also. You can try them and see what sounds best to you. No right or wrong there. If you have a room correction module and microphone you could use them to help get a flat room response.

semente Posted October 19, 2017 Share Posted October 19, 2017 From a Q Acoustics manual: Foam Bung The Concept Series speakers are rear ported and designed to work best with some space behind them i.e. 200mm or so away from a wall. If you position your speakers close to a wall/corner then the foam bungs should be inserted into the rear ports or there could be too much bass. Ensure bungs are fitted snugly into the port without inserting them too far. You will find the level of bass is reduced but definition and bass extension is increased. Experiment to see what you prefer and try making small changes to the position of the speaker to optimise the final result "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment
