Don’t stand so close to me

[VictorSF]

Any recommendations for speakers that play nice close to the wall?

How close?

JBL makes , or used to make, a model designed to be placed near walls. IIRC Floyd Toole mentions it in his book.

Or much better get a nice PEQ or DSP and you don't need anymore to hope that by trial'n'error you get a loudspeaker with the exact inverse bass frequency response of your room response.

True but it is not as easy as it seems to find the good settings.

Its not easy for a newbie but the result is more promising than buying loudspeakers by trial and error and with all smartphones you can nowadays measure the bass region sufficiently to correct the usually 2 problematic lower modes, there was even a nice method doing so by ear and adjusting the PEQs decribed by Neumann.

Many companies make wall-mount speakers, which are designed for the application. Depending on what you consider "close", these may be a better option than standard speakers with unknown wall interaction characteristics.

Those have always intrigued me. I would love to see some real measurements on them, as most subjective reviews have been good. They rarely come up for sale in the used market, so either very few have been sold, or the owners of them are happy and don't feel the need to buy something else.

Even Toole doesn't say anything 100% working to fight room modes, probably he is a n00b as well...

I was told speakers should be placed at a minimum of 35% the speed of sound divided by the lowest frequency at -3 db.

Given a temperature of around 25 Celsius, this gives 120/fqcy in meters.

So if your speaker goes as low as 55 at -3dB, minimum distance to avoid CANCELLING sounds is 120/55 or 2.2 meters.
For 80 Hz just 1.5 meters are called in.
Turns out floor standers go as low as 14 Hz, asking for 8,65 meters...and since they think you are not having such a room, they recommend placing them as close to the wall as feasible.

Funny, isn't it?

If you don't mind buying used the KEF C15 and C25 where designed for placing against a wall.

KEF LS50Ws have a software adjustment for near-wall placement. For the used market, Revel M20s also have an adjustment for near-wall placement.

What for the other frequencies? -6dB ? -9dB?
That is to say: which slope?

It works. To follow the formula I had to put my speakers and subs on the lawn, but no more standing wave issues.

Stereophile had a review of their floorstanding speakers. Their measurements were awful. The manufacture wrote back saying it was because nearfield measurements don’t correctly capture their complex output, only in room. John Atkinson replyed pointing out that in room measurements were made and shown and they were poor.
