What are some quality bookshelf speakers that can actually be used on a bookshelf?

OK, I have concluded that the dated Spendor S3/5 speakers used in my office on a bookshelf need to be updated. It is not an ideal setup and there is zero chance to change it but I need to have music.  I have a shelf about 2.5 feet above and in front of my head on which the speakers sit. The shelf is about 14 inches high and deep where the speakers have to fit. My PC monitor sits about 24 inches out from the wall the shelf is on on a desk and my printer, router, phone etc sit under the shelf on another platform which has no room for speakers. So I am listening to speakers above my head from that shelf with only a little room behind them to the wall. I prefer passive speakers as I have a Marantz PM8005 and currently run a Wiim Ultra for streaming while working. I live in Hawaii, so no place to listen. I am guessing that I need something that has no ports or ports that face front or can be stuffed. Listening is eclectic from jazz to blues to rock to Hawaiian slack key and other acoustic guitar. I figure I can spend up to $1000 US (new buy)  but if there are things a little below that, that is ok too. I figure I am looking at AMZN, Audio Advisor, Crutchfield, Music Direct as likely sources to save on shipping. I have done some searches on stuff but been overwhelmed with how much is out there so I am hoping some of you have faced similar needs and filtered out the winners. I tried some of the online YT reviewers but there is lots of noise from folks that dont seem to be really knowledgeable. In my other systems, I am using Ohm 2000s and Kef R300s. I have been happy with the Kefs and like their sound but they are bigger than the space is so thoughts of trading up died....Thanks in advance for any and all input
