    But I mean your center channel is only like 80% of the sound from a surround track so why would it matter, right?

    A couple of weeks ago I bought the re-mastered Godfather Trilogy. So, I am watching the Godfather, and it sounds like muffled c r a p at the very beginning, and then went silent. WTF, I said. Then I realized the amp running the center and two surrounds was turned off. First time that ever happened. In the past I have forgotten to turn on the two amps driving the fronts, and the center carried the load without to much trouble.

    I'd use the Left Rear One for my center on top of my TV Stand, with the TV on top.
    That's the spirit! :p

    Cool photo @mhardy6647

    From an old Altec catalog --http://www.lansingheritage.org/html/altec/catalogs/1975-pro.htm

    Gary Kaufman is still planning to do an all Altec HT, last I knew.
    A5s topped with 1505 horns/288 drivers and A8s for surrounds.

    As a not completely irrelevant aside -- Gary's A5s are on the very short list of the very best sounding loudspeakers (to my ears) that I have yet heard.

    r4qdxu4lsni8.jpg

    An A5 on its side wouldn't make a good center channel -- but it would (and did) make a superb center/dialog reproducer in classic cinema theaters for decades.

    The A8 is (was) a really interesting 'slender' VOTT -- the interesting part was the use of a 90 degree bent treble horn... and that's interesting because that horn (the Altec 32B) was the direct descendant of the Western Electric 32A horn. Both flavors of 32 horn are held in great regard in certain circles to this very day.

    Isn't a center speaker designed in terms of snd quality to perform as voicing speaker? Aside from size and driver layout i was under the assumption that unlike a full range spk it was designed to remove the lower bass and possibly extended highs to more closely mimic the range of the human voice in a attempt to eliminate any colorization that using a full range spk may add.
    IMO as i got better quality gear the term sounding good got more subjective and i began to describe previous gear as sounding ok,decent or acceptable in relation to improvements

    I'd use the Left Rear One for my center on top of my TV Stand, with the TV on top.

    I'm not quite sure how you are going to accomplish that when:

    A.: There is a massive, high frequency, compression horn array on top that is critical to the sound otherwise the speaker is only going to reproduce sounds equivalent to God farting through the same trombone Charlie Brown's teacher squawks through.

    and

    2.: If you are planning on laying it on it's side, it's going to end up pointing mostly at the ceiling with the "sweet spot" several feet behind and above your head. VOTTs are cool and all but the entire reason for the directional horns is because their off-axis response is pretty poor since they are the high efficiency Alnico magnet structures and the tweeter is buried in a couple feet of horn structure. If you didn't have that structure, the tweeter would just sound like a buzzing, giant bee stuck to wall that was listening to a pretty poor transistor radio.

    In a theater, that's no big deal because even a 2 degree shift in off-axis response translates to several feet if not 10's of feet at the listening position in a theater. At home, though, your listening distances are too close to realize such a small shift in off-axis response.

    That off-axis response issue is what people are talking about here in regards to your use of a tower as a center channel.

    While your use of a full-range tower may "sound good" to you, what you are actually doing is over-emphasizing your center channel info. This causes the majority of your programming information to be emanating from your center channel which does not get the full range of your audio programming. It's intended to be where dialog comes from. Dialog coming out of all channels instead of just the front would cause your system to make anyone speaking to seem like it was in your head. By using such a powerful speaker for your center channel, though, you are skewing your HT field to the center and diminishing your surround effects.

    On top of that, if you have, say, a 3.5 foot tall tower (42" tall) then your tweeters are typically positioned to be about 32-36 inches off the ground. That is your typical range for head positioning at a seated point at the listening position. That means that the tweeter is 6-10 inches down from the top of the speaker. So laying a 42" tall speaker on it's side makes for a center point 21" from either end. So your tweeter is now a foot or more from the center of the speaker and skewed to whatever side it's closest to.

    Your tweeter might have good off-axis response but the off-axis response is typically -3 to -6 dB as you get further from centerline of the tweeter. That means, to get similar performance from your tweeter in your high, off-axis listening position, you have to turn the center channel up much farther in gain than the rest of the channels to hear it at the same level as the other tweeters in the system to preserve your front sound stage. That draws all of your attention to the front then as well.

    To further your problem, check out the speaker baffle (the surface the tweeter is mounted in) and see what it looks like. Most tweeters are round so they should have the same off-axis response in all directions around the driver. However, to get your stereo imaging right and to minimize undesirable reflections off of ceilings and floors, designers and engineers will design baffles that will help stifle vertical off-axis response and emphasize horizontal off-axis response. In a properly damped listening room, this can create the impression of a wide and deep sound stage which mimics the environment of a live performance.

    Putting a tower speaker meant to be used in a vertical orientation takes that tuning of the off-axis response and puts it 90 degrees off plane.

    While sonically, the tower speaker might give you a sense of power and authority when used as a center channel, what you're really doing is skewing your sound stage to one side and killing the response field that a center channel usually enjoys.

    This could also be a huge contributor to your source issues in this thread:
    http://forum.polkaudio.com/discussion/176684/anyone-use-different-output-levels-for-different-sources/p1

    The reason for that is because you likely have your center channel way over boosted to compensate for this arrangement and when you play music or some other 2-channel programming, your stereo pair which would handle this duty are not set at an adequate gain level because of the skewing your tower as a center causes.

    It's just going to look really silly and unless it's under a very large projection screen and sitting 20 feet back the voiced image is going to be noticeably shifted.

    Use the right tool for the job imo.

    The above Craig's List/ Klipsch front speaker array is actually somewhat inspiring. It shows how creative placement can put the most sound into small spaces. And the woofer cones on those Klipsch Speakers are reminiscent of the new Signature S55s! Hey you folks out in Polk speaker land that just landed the S55s, go for it! You now have a visual representation of what is possible. By freeing up extra space, you just may be able to squeeze a ping-pong table into your living room.

    No it is not inspiring.

    As many people tried to explain to the op, there is a reason a center speaker is designed the way it is. With the tweeter in the center, for instance, as well as a mid woofer on each side of the tweeter.

    All dialogue, for an example will shift to the right side of the screen, the way the speakers are shown in the picture. There is no way any calibration, auto or manual, could correct that bad of speaker placement.

    this could be a bad movie title or something. Also could be for the banjo playing and pig squeal sounds.

    Is that a beer can maybe PBR by the wall next to the right speaker.

    LMAO....starting the morning off with a good chuckle. Maybe the OP needs to define what a "seamless soundstage" is to him. My definition is certainly different from his.

    We all have our definitions of what good sound is, that pic though, doesn't fit my description. I'm just wondering now, why he felt a need to upgrade the horns. Could it be he somehow damaged the originals ?

    A band saw down at the lumber mill and some duct tape could turn that floorstander into a real center channel speaker. No problem.

    Good point -- duct tape has those ideal physical properties of stiffness, strength, light weight, flexibility, and it's a "lossy" material, to boot.

    Plus, as long as you buy the "silvery" kind, it'd even look like titanium. You know, kind of.
