Michael N Posted July 31, 2021 Posted July 31, 2021 (edited) Due to unavoidable speaker placement, the rear speaker ports are probably not doing their thing very well. I wonder if placing a vertical stand made of say chip board or the like behind the speaker would help? I'm not at all technical, and any advice will be most welcome. Many thanks.

Can you explain what you mean? The speakers look like they have plenty of space behind them - this is a good thing 3
tubularbells Posted July 31, 2021 Posted July 31, 2021 Remember bass at the frequencies ports operate at is omnidirectional so as long as you have ample space behind (which you seem to have) then technically it doesn't matter whether the port is front or rear firing as it will sound the same. 2
Michael N Posted July 31, 2021 Author Posted July 31, 2021 Thank you both for the comments. I thought that for the rear ports to operate as they should, there needed to be something (hard) behind them! It seems I'm mistaken, and that's good as they're in a fairly open positions so should be fine. I don't have an issue with bass response, though I'm also using a small (old) REL subwoofer. Thanks again.

Rear ports like lots of space behind them. enjoy! nice looking speakers by the way 1

It seems I'm mistaken, and that's good As per above posts, you don't want your bass sources (in your case your rear ports) too close to room boundaries...rear ports need some room. "Hard" surfaces reflect sound back into the room - but it's frequency dependant depending on the acoustic rigidity of the room boundaries: A typical Gyprock wall will reflect higher frequencies back into the room, absorb some bass frequencies based on the Gyprock walls flexing, and let lower frequencies pass through. A cored besser block wall is "acoustically rigid" and will reflect all frequencies - the bass just bounces around within the room taking forever to decay. Keeping treble in the room is generally regarded as a good thing - so your room doesn't become "too dead" Keeping bass in the room is generally regarded as a bad thing - "boomy" bass, "one note bass" etc I have a lightly constructed room that lets low bass out with the "in room" bass "reasonably under control" using loads of absorption. Aesthetically my room is a disaster - but it sounds great - bass is amazing. Mike
Michael N Posted August 2, 2021 Author Posted August 2, 2021 Appreciate those comments Mike. Many thanks. I'm about to begin setting up my new Pro-Ject X2 TT, though still waiting for the cartridge to arrive - Nagaoka MP-200 (from Japan).
