Can I turn my 2-way Bookshelf speakers 90°…?

….and not negatively I mpact audio quality?  

I have a spacing need to potentially turn my bookshelf speakers to be horizontal.   Does this impact audio?   These are “typical” 2-way box speakers.  

Thank you…


I have a small set-up in my hobby workshop, a 10' x 12' room that has a 9' ceiling. It's occupied by two work benches set in one corner to form an "L" with wall mounted cabinets over them and one seated work station per bench. Since the opposite corner holds another work bench, the only available floor space holds an 8" sub in one corner. My two Elac B6 Debut's are sitting upright on top the wall cabinets at each end of the "L" at 90° to each other. This works surprisingly well, and with a tweak of the balance, the 'sweet spot' becomes which ever seat I'm sitting in. It is possible to make the system work with the room when the room dictates how the system can be set up.

Properly engineered 2-ways generally exhibit wide, well balanced response in the horizontal plane, but often some noticeable irregularities in the vertical plane, due to the ways frequencies shared by both drivers tend to interact in the crossover band.  For a vertically aligned speaker, the tweeter height is not the real issue, it’s finding the sweet spot where the midrange is not “sucked out” by phase cancellation, and a combo of height and toe-in is usually successful.  Rotating to horizontal makes the likelihood of achieving this result far less.  I suggest using “coincident” 2-ways if you must do this.  KEF, Tannoy, and Elac are known for this and more recently MoFi.  Andrew Jones is a big name in this field.


It's not ideal for imaging, and the phase relationship with the woofer at the crossover becomes an issue.  But if you don't care about that then go ahead.

My Roksan Darius MkIV (from the glorious 90’s) were designed to work like that, in a 90 degree angle. In fact I am listening to them right now, and the soundstage is huge with pin point imaging. Although very tough to set-up, all efforts were rewarded with sublime sound: they completely vanished in the room, and deliver very tight bass, clear and sweet treble.


That said, I never experienced that extreme toe-in with any other speakers, in fact, I prefere no toe-in at all with my Thiel, Totem, Kef and Quad speakers.
