    Back reflex ports and corner placing

    If for space reason a big speaker (let’s say a K2-9800 type) need to be placed in room corners, let’s say 1 feet off the wall(s), is it then better to have the reflex ports to the front or to the back??

    I almost always drop the ports on the back. That way the port loads into the corner and any port noise or leakage is not aimed at the listener. It also gives you a nice clean refraction free baffle. One foot should be enough room so it doesn't intefere with the function.

    I would put them at the rear in a large speaker. Bookshelf speakers are a different kettle of fish of course.

    Am I the only one here wondering what you are up to...Ummm, the mind boggles

    Rear for sure. Every wall/boundary gives you 3db more output/bass reinforcement.
    Like Andy said, what are you up to? Getting ready to climb the mountain?

    Try to go with the largest vents you can and put them on the back.

    I have two B460 clones, with the 2245's and 3 ports in the back, facing the wall, in a corner, in two different systems. Other than having to re screw all of the sheetrock to the studs facing them, they are very tight and sound great below 70-80hz. This also leaves the fronts smooth, except for the "Loudspeaker Components by JBL" vintage logos

    The best solution I've heard has been to port out of the bottom of the speaker. It's clever. It certainly seems to make the speaker easier to position in the rooms I have tried. Rear facing ports are a mare here in the UK.

    Apologies David - an abreviation of the word nightmare. I missed an apostrophe.

    I've never heard a rear ported speaker that was easy to position in room without eating into valuable listening space.
