Raidho speakers with Audio Research Tube amps

I had a buddy who had an ARC LS26 and amp (I forget the model) with Raidho C1.1s.  Great combo.  
Raidho makes great speakers.  Room placement is critical.  They need 2’ minimum from back wall and 9’ between them.  If you get side firing drivers, proximity to side wall also is an issue.  If no side firing, they can be quite close to the wall and do well.  

I have.  I love the tweeter and the soundstage is truly spectacular. 

They are tough for room placement because of that side firing woofer. In the right room they are brilliant.  You probably need a room that is 20' wide to have enough room to not get too much reverberation from those woofers.   You also need a full 3' off the back wall.  Not a speaker for every room.  

Technically I suppose it is a choice but you would have the bass drivers aimed toward each other, your equipment and the back wall.  It would enhance bass volume greatly but harm clarity I think.  

The key with these speakers is a little flex in placement to get the soundstage to come together.  When it does, listening is...addictive.
