The ones I used, and many others have are RSL, c34e’s. $125ea. They have a 15° angled baffle which will help “aim” them closer the the LP than a regular IC speaker would, and have wide dispersion which is one of the things Dolby calls for. Imaging is also excellent. Tonally, I haven’t any idea if they’d match your other speakers, but ime by the time you run audyssey and consider everything else, they should work very well. Coaxial speakers tend to work very well up there too. My mind is slipping at the moment, but there is an affordable popular coaxial speaker that’s also been reported to be excellent on other forums. Hopefully the name will come to me after some more coffee…..
