@Music1969 I tried an experiment comparing a small speaker to a large speaker here:
https://audiophilestyle.com/ca/revi...ker-comparison-with-binaural-recordings-r768/
I equalised both speakers to have the same frequency response (within what can be done in a home environment) and both had (the same) subwoofers. One has to be a bit careful with terms, as I "thought" the horn loaded system would be more "dynamic" than the inefficient Kef LS50 bookself speaker. I also thought the big speaker would sound "bigger".
I made binaural recordings for both speakers. You can listen to them over headphones to get a good feel for what they sound like. I then level matched and spliced the binaural recordings together and switched between the two speakers every 10 seconds. I left some of the "splice" sound in so one can get the cue that the speaker had been switched.
I thought big speakers sound more dynamic than small speakers, but that isn't what I heard on the binaural recordings. Given similar frequency responses, the two (wildly) different speakers sounded more alike than different, with the same dynamics., to my ears. Also, as long as the bass response is the same whether one is using a large floor stander or bookshelf with subs, also sounds more or less similar as far as "size" of image created. Of course, there are limitations, the first being the absolute SPL that they output. But both easily play at reference level (i.e. around 83 dB SPL C weighted at the listening position).
Another surprise is the audible difference between the two speakers are their directivity indexes. The big speaker, high directivity and the little speakers, wider directivity. So the big speaker has less "room sound" while the smaller, wider directivity speaker had more room sound mixed in with the direct sound. You can hear it clearly on the binaural recordings. I think that change in tonal response is the main difference as they both sound the same from a "dynamics" perspective. But maybe you will hear it differently. Give it a listen and let us know what you hear...
