Buchardt Audio S400 MKIIs......about $1,700 used. I've had them for a couple of years, and am still loving their sound. Wide and high soundstage (though average on depth), really good instrument location and separation, nice tight and detailed bass, and extraordinary mids, vocals are a standout. There are dozens of positive reviews to be found.
They do not have a port, but instead have a passive radiator which allows them to be close to the front wall....I have mine about 14" right now.
