Acoustic Compensation - Hi-Fi News 1964

This article features an unconventional approach to the problem of securing smooth bass in domestic rooms... Basically really big horns. My fave.

This article and pictures were sent to me by Baptiste Anders. 

I have been getting a lot of reader submissions latey which I think is very cool.

A few pictures of Bo Hansson's systems. Bo hansson who sadly passed away in 2011. Besides having a big bass horn he was also the founder of the record label Opus3, Rauna loudspeakers and Opus3 Cantus tonearm.

I can tell by looking at these puctures that we would have gotten along very well.

Both of these systems are in Sweden. This second system was posted on www.faktiskt.se .

 How did they get these large concrete horns in the house???? Wow......
