However, if you space is tighter than that, then there are perhaps other speaker in the same price range that might be a better choice.
The SVS Ultra Towers utilize side-firing woofers located at the bottom of the cabinets, a configuration developed by Acoustic Research for the AR9 in the late 1970s. The AR9 utilizes one 12" woofer on each side of its enclosure (four 12" woofers total for a pair of loudspeakers). I bought a new pair of the AR9s in the early 1980s and still use them today. They offer incredible performance. I have tried many times, and failed, to find better loudspeakers over the years, auditioning models priced up to about $13,000.
It may not seem logical, but, in my experience, locating the woofers relatively close to a sidewall presents few if any sonic problems in the bass region. Out of necessity, for about eight years, I had the right-side AR9 about 10" from the sidewall and the left one about 6" from a bookcase on the left sidewall. The bass response remained flat, smooth, and not exaggerated at all, as I had initially feared. In my subsequent apartment and today's new house, where the sidewalls are several feet away, the bass response sounds the same as before.
Note, too, that SVS's user manual for the Ultra Tower gives no specific recommendations about sidewall placement. The manual provides only general advice that pertains to any loudspeaker. The manual does suggest inserting a foam port plug in the back of the enclosure if the speaker is utilized in a small room. The manual explains that the plug creates a "sealed acoustic alignment"--just like the AR9. What's old is new again.
