Its also worth nothing, that center channel speakers, like the C-2 and the one in novisnick's image above, where the "midrange" speaker is below the tweeter and only the woofers are in an MTM configuration, won't experience the same horizontal lobbing issues. Actually they will, just in the FR bands served by the drivers. Maybe, in the frequencies of woofers, lobing and comb filtering isn't usually an issue. |

Could all the speaker companies have it wrong with the standard center speaker? |

"Wrong" and "Optimum" are two different things. Home theater center channel speakers are a compromise design because of the realities of placement in the typical home. How many homes have the required acoustically transparent screen and projector setup required for a proper cinema installation? The designs as pictured with the mid-tweet in a vertical arrangement should perform better than a typical D'Appolito-based MTM, but any time you have multiple drivers on the same plane playing the same frequency band, lobing and comb filtering will occur, it's just physics. (the exception to this is low bass drivers as the first two or two and a half octaves do not exhibit these effects normally.) The end result in any particular room depends on how these effects impact the sound field at the primary listening position.

Keep posting DYohn, I usually pick up some good tips.from you.
Novisnick, that system I would like to hear, especially the Center.

My center channel speaker was actually marketed as a LCR speaker, and can be placed both horizontally and vertically. Its actually a very close match to my mains top portion, just minus the sub section below. The mid and tweets are exactly the same drivers. The tweets are offset from the center to about the 1/3 position.
That being said, I took a lot of time with this topic when designing my TV cabinet. So I phyically tried both configurations. There was no doubt that vertical sounded better. So for weeks I tried to figure out how to make my cabinet work and look good doing it that way. But in the end it required way too many other compromises (TV too high in the air is one) so I went back to horizontal.
What I ended up with was something that sounds 98% as good, maybe more. I don't experience any of the issues described here. Its well known to be a great center speaker so who knows.
I will say this, below the TV sounds much better than above the TV. And not having the speaker pointed directly at the listener is also key for natural sounding vocals. YMMV.

Keep posting DYohn, I usually pick up some good tips.from you. Novisnick, that system I would like to hear, especially the Center. Thanks, the CC-690 Studio V5 is a marvelous center for both movies and concerts. Designed in every way as a center channel that plays and sounds as close to a vertically standing tower speaker as possible. I’ve never experienced any sound problems with it. My HT is a Paradigm Studio 100 v5 in a 7.2 configuration. Two PSA Subwoofers with duel 15” drivers. Home Theater at its best, sans Atmos. Showing tonight is a yet to be viewed 4K version of Avengers Infinity Wars. I can’t wait! Our forum is truly blessed with so many intelligent, knowledgeable friendly and sharing friends, DYohn being one of them. Teachers and Students we all are. @texzick , when you find yourself this far south just give a shout, we’ll make a day of it! |
