Last year I spread the Beovirus to a friend. Huge on music but a very old poor sounding system.
Her first choice was a beocenter 2 and very quickly lab 12s. This was a music only set up.
I borrowed a set of 12.2s for the week end from my very helpful dealer. They came on a set of stands from the shop display. We spent a day trying them in various positions on and off stands with surprising differences.
The 12s were clearly better on the wall. They sounded better (a Lot) with the acoustic lens on top.
Monday came, the demo's returned and a pair bought.
Now I had the wall brackets it was easier to get a more exacting result.
Again lens on top was better but more surprisingly, speakers closer to gether.
Then I tried a bl2 in all its settings. With the bl2 turned down to wall and set up 3 it was not obvious in the music but did " disperse " the music better around the room. I am sure there is an audiophile name for it.
This week end I did the same with BL12.3s for a music/bv set up.
Again lens up was better but the bl2 (set as above) was not necessary for music. In fact I was amazed how much base the 12.3s can put out.( way more than I need) I have not tried the bl2 with the bv but as this is in an apartment I am not to inclined to push it with the neighbours .(yet 😜)
The lens height with the 12.3s is 140cm and in olde money 55inches.
