Yup. If you don't have room for the Cab to open up and disperse properly they are an horrific option.
I am also not sold on them being the best "low volume" option. If you want some speaker breakup
when using amps lie an AC-style Vox or a DR-style Fender then you are not going to get that with a
4 x 12 at low volume.
I also agree with what
@Life Eats Life said about speakers having a sweet spot. At low volume it is
challenging to get 4 speakers there. Much easier with one.
Also, live and studio are different applications. Jimmy Page on stage at MSG = 4 x 12. Jimmy in the
studio not so much.
One option is never the answer for EVERY situation. Unless youz a damn fool!
