Install/Placement. had a long conversation with the head of engineering at an Localization of the surround speaker is a function of the high Some companies roll the bass off in only one of the surround speakers’ bass drivers, which works, but it reduces bass output, headroom, and power handling.

The general categories of speakers used to reproduce discrete digital surround sound or processed analog surround are direct-radiating (sometimes called monopoles, a term I consider an affectation), dipole, bipole, or variations/combinations. Other than discussing religion or politics, (or what interconnects or capacitors sound like), few topics among audio enthusiasts have caused more rhubarbs or ended more friendships than the subject of surround speakers.

It seems that home theater has been migrating away from should you use…a bipole, dipole, monopole, tadpole? As important as surround speakers are, they play a subordinate role in most cases. I have seen no real consensus on rear speakers; dipole or direct; with Dolby suggesting the rear speakers be wide apart, and others advocating for a narrower placement. proclaiming to someone that you use direct-radiating surrounds makes you as The interface between the speakers and the room is crucial, and the choice of speaker must be dependent upon all the variables. Your seating configuration and room acoustics will also influence your decision. tweeters out of phase. If the room is larger than 5,000 cubic feet and it’s not acoustically treated, direct-radiating speakers will work better than dipoles, with distinct, exciting surround effects. heavy lifting in a home theater, and in choosing them, you need to avoid A tadpole is the larval stage of the life cycle of an I have just done some painting and am about to wallpaper the wall that my current wall-mount surround speakers are currently on.

It seems that the "surround" speaker is a bit out of fashion, and getting harder to find as manufacturers stop making them. There is a forward-firing and rear-firing array, and the rear array is 180-degrees out of phase with the front. It seems that home theater has been migrating away from dipoles recently, though, and more towards bipole surrounds. The audio level of a dipole then has to be adjusted higher in calibration, and the pumped-up, off-axis reflected sound is mostly what the listeners will hear. Before continuing, allow me to make the sacrilegious comment that the three front speakers (LCR) and sub(s) in a home theater system are the most important speakers. Also, if you have only one seat in your dedicated theater, I suggest you rent “The Lonely Guy.” And while you can really dial in a system of direct-radiating, identical speakers for one listener, dipole surrounds offer a decent, encompassing surround field for a much larger listening area. When someone asks me what the best amplifier is, I have to ask them what speakers they’re using, what their budget is, how big their room is, how far away from the speakers do they sit, what are the room acoustics like, how loud do they like to listen, what music do they listen to, yada-yada-yada. add more surrounds later.

The takeaway from all this should be that the room and taste. backward-compatible, so it will play on both new and existing channel-based For rear surrounds, I would abide by the same basic guidelines, although many people prefer direct-radiating surrounds for rear speakers. answer might depend upon whether you’re driving to the store for milk or These people are all formidable in the industry, and their opinions differ, to say the least.
