Recently bought two of these SSCS5 speakers to match on separately purchased stands with an SACS9 subwoofer I have enjoyed for three years and an STR-ZA3000ES (July, 2018). The STR-ZA3000ES has been replaced in the Sony ES lineup by the newer 3100ES, which includes Dolby Atmos, DTS-X, Ihiji, Phantom Surround Back, and other upgrade features. Cutting to the chase, the SSCS5 speakers are simply superb to my ears, and seem to work perfectly in the match with the Sony ES audio video receiver and my great old workhorse, my Sony Core Series subwoofer. I did endless research and auditions of many products and brands. I have read most of the reviews about the Core Series speakers and countless other speakers, many of them superb and possibly on my future shopping lists. The accolades for the SSCS5 are not hype, at all, in my humble opinion. Anyone interested in getting amazing stop-you-in-your-tracks sound out of reasonably affordable audio gear would be very wise to put these extremely capable and affordable bookshelf speakers on his or her short list to consider. One caveat I offer is that although the SSCS5 has fine, present, defined, clear, and punchy bass, adding a fine subwoofer such as the SACS9 can definitely help you feel better and get your bass on if you happen to be one of those "needs more cowbell" types. For reference, I just played Jethro Tull's remastered Thick As A Brick and also some of the best and most bass-demanding Led Zeppelin remastered tracks on CD's - up very loud (>100 db but not quite to pain threshold) with and without the Sony sub engaged. It all sounded satisfying with and without the subwoofer on, and I would have been perfectly happy to have kept listening without the sub; but I guess with a very nice (or naughty) subwoofer like that SACS9 just lying around with nothing else to do, I just wanted "a little more cowbell." I hope this helps. Cheers!
