Bookshelf speakers that sound good on a SHELF or SIDEBOARD

The LS3/5a and its successors have been the classic choice. For years I happily used the LS3/5a as my desktop speaker, and only recently replaced it by the far superior Harbeth P3ESR. Both of them have suffered a bit from bass boost as a result of the proximity of the desktop surface. I have cured most of this by raising them some 8 inches using little isoacoustics stands. In my case that had the additional advantage of bringing the tweeter up to ear height.
The remaining lump I cured with an equalization graph in REW and uploading that into the Equalizer APO software on my desktop PC (used as a source). Traditional tone controls will also do this, to some extent, and not as precisely. I do not think you can avoid using a bit of equalization, and the more precise the better. But with it, you should be fine.

My room is the same as yours. I am using a Pass labs integrated mated to NHT c-1. These are very small and sealed. I am also using a Bowers and Wilkins DB3D sub. Speakers are mounted on the wall and my room is treated. I can tell you that there are not many full size speakers that sound better. I have been into audio since I was 12 (73 now)  and I have the best sound I have ever owned. I’ve owned NHT 3.3’s and Krell.

I have some Totem Model 1 Signature speakers. Original owner. 

Includes two Totem Signature main speakers, a center channel, and standard model 1s too.

Initially they were used for reference validation, and now saved for a future 2nd den room reference system. I used them a few times to compare to my own custom build speakers to see how far off track I get on my own builds. While I don’t use them much any more, and may sell them soon, I tested them recently on a shelf setup and was surprised recalling once again how great these speakers really are. Had forgotten, they are amazing...

They primarily sit on 6" tall metal stands on a side shelf, about 1.5ft from the wall, or sit on 24" stands about 9’ apart. Sound great in either case with my 10w tube amp or my 200w solid state amp.  Totems are a real treat.

+3, f or the REGA RS1 or its immediate predecessor R1
The current model is the RX1

review of the R1

These bokshelves are ideal for close placement to back walls: they even have OEM brackets available as inexpensive accessories for mounting on the wall.

"..... The Rega R1 becomes my new budget reference speaker. In addition of its ability to get the fundamentals of music right, it adds clarity and resolution, and an ability to lay out a vivid and coherent 3-dimensional stereo image. In small room applications, what more could you want?...."

highly recommended.
