Let me google that for you

The corners behind the speaker is usually where bass gets amplified by the geometry of the room and where standing waves are created. Bass energy is stronger in corners.
Do you really want your turntable in such a place?
If you read my post, dimkasta, you would've understood that I said I had my TT in the corner for 25 years (I've now moved), with no problems in terms of nbass boom or feedback.

But, yes, that wall-corner was 6m away from the nearest speaker. (Whether this makes a significant difference, I have no idea.)

Andy

Seems pretty logical assertion to me. Either way, bit off topic.

I was talking about the corner behind the speaker in layouts like the one in Salas' photos (which triggered the comment in the first place). Which means one or one and a half meter at best. The issue is present theoretically in every corner of the room, but if the rig is decent then the effect should be minimal in corners that are not directly behind speakers.

Although he is living in a small space and he would not have much choice, luckily that TT is ~30kg with a reputation for withstanding external vibration very well.

Its mass per $ ratio in the particular model's price bracket is a notable characteristic I would suppose. Don't know if are others with comparable approach in that range, haven't researched. Notable alternatives there should be many nonetheless. Sprung sub chassis, gimbal arms, etc.

Aah, OK. Yes, I would agree that 1.5m away might produce a worse effect than 6m away.

Unfortunately, in my next house, I am forced to locate the TT on the front wall, in between the speakers. So it will be, at most, 1.5m away from the nearest speaker.

On the basis of theory, to attempt to get a minimum-resonance position, I have decided to place the centre of the TT plinth on the Golden Mean of that wall. So we'll see how it goes, when we move in mid next year.


Regards,

Andy
