There's a review in the latest issue of Recording Magazine.In a "typical" rock band,if the bassist is using a 4 string bass,the fundamental of the open 4th string is 42.something HZ,and some kick drums can go even lower than that.If the bassist has a 5 string w/low B,the fundamental of that note is 31HZ.I read the review quickly,seem to remember it saying that the PS5s would need a Subwoofer.Cheers!
