I have marantz 1509 and i went for Indiqaudio custom LCR and very satisfied with them. They are ~95db (one of the reasons for me to go for them). Now many FMs have these and you can reach out to them for their feedback (to avoid my biased opinion

). You can get these custom FLCR in your budget. They are slightly larger than a typical BS but not as tall as the FS.
