I know this is an oldish thread, but this message is in context here.
I've got 2 Speedwoofer 12s, with wiim ultra crossover set at 90hz, that I stand my stock-standard Yamaha ns-1000m on. Setting these active subwoofers to maximum volume allows me to set subwoofer level in wiim to -15db.
Room correction then still sets PEQ for 20hz to 90hz to high negative values to compensate for the still high subs volume, so I'm not too concerned with the PEQ settings from 90hz to 500hz, the max frequency I do room correction for (using latest beta with this option) and which is also the ns-1000m crossover frequency to the midrange.
I've found, with the help of previous wiim room correction, that the correct midrange and tweeter attenuator settings on the ns-1000m are -4db and -3db respectively, so the speaker sensitivities are probably closer to 87db than the default 90db in my case.
With the above set I've determined the highest pre-gain level I can set in the wiim is +3.5db with 100% volume.
The song that suggests I shouldn't try anything higher on pre-gain is Lionel Ritchie's Three Times A Lady (2008) on Tidal - which is then showing 372watts peak hold on my Yamaha mx-1000 amp and the wiim vu meter only then moves past the +10db level by quite a bit. The music sounds clean but my gut-feel is that the wiim has possibly started or is close to digital clipping
Other Tidal songs, like U2 With Or Without You (1987) and James Taylor Fire And Rain (2011), also peak at about the same >370watts on th mx-1000, but don't peak quite as much over 10db on the VU meter and give me the impression I could go a bit higher still on the wiim pre-gain if it weren't for the Lionel Ritchie song.
I then dialled back to +3db pre-gain on the wiim in case there are other songs in my Tidal playlist that are more demanding than the songs I've tested here.
I've made a feedback suggestion to wiim for a digital vu meter screen with peak hold as an option (love the digital peak hold watts on the mx-1000). Reading this thread now, I realise I should have added 'accurate vu meter' to the suggestion.

Not much luck yet.
