Dipole vs Bipole Speakers: What’s the Difference?


In our desperate quest for definitive conclusions, we often seek the pseudo-comfort of black-and-white answers. 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. Should you use five or seven identical speakers? Should you use dipole surrounds? How about monopoles?? And what do these terms mean? 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.

Surround speakers are also important; just less so, and yes, I actually said that. If you have a mediocre front soundstage, your You can add more surrounds later.

The front speakers and subs do almost all of the heavy lifting in a home theater, and in choosing them, you need to avoid compromise as much as possible. As important as surround speakers are, they play a subordinate role in most cases. However, the basic premise for choosing surround speakers holds true for additional surround technologies.

Check out our recently added YouTube Video discussion to gain further insights on surround speaker types. Surround Sound Speaker Types: which are the best? Floyd Toole. Direct-radiating surrounds are like your typical front speakers in that they use drivers that fire forward. Audio purists tend to prefer this setup. All of the surround information is aimed at the seating position, and reflections are not utilized, or at least not as much.

Proudly proclaiming to someone that you use direct-radiating surrounds makes you as cool as if you told them you never drink blended whiskey, or you ride a single-speed bicycle, and you listen to Alter Bridge. In this type of speaker, there are usually two arrays of drivers which face in opposite directions, and they are in phase with one another. The idea is to fire the surround information into the seating area, but not directly at the listener, to avoid hotspotting.

Focused, direct surround sounds, at close range, can be a distraction. Bipole surrounds actually work quite well in the right setting. Bipole type speakers are also sometimes offered as front channels too. Think of the Definitive Technology towers as an example. A tadpole is the larval stage of the life cycle of an amphibian, and not to be confused with a dipole.

Dipoles or dipolar speakers are similar to bipole speakers, except one array usually the rear array is out of phase with the front array.

Dipoles require a bit more explanation. There is a forward-firing and rear-firing array, and the rear array is degrees out of phase with the front. What this does is create a null cancellation on-axis, with a resulting level drop of 8 dB.

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. Dipole surrounds produce a less-focused, diffuse, enveloping surround field. There are different driver configurations for surround dipoles, complicated by the fact that when one 2-driver array is out of phase with the other 2-driver array, bass is effectively cancelled.

This problem is addressed in a variety of ways by various speaker designers. Some speaker companies ignore the loss of bass, and just leave both arrays out of phase into the bass region. Some dipoles use a single woofer and two tweeters and only run the tweeters out of phase. And still other dipoles are out of phase down to approximately Hz, below which the bass drivers are shifted back in phase, for optimized fullness.

Acoustics should be addressed first. Reflections from front and back of the room are just noise so there is a good case for deadening them to reduce this effect. A general rule, "mix it up": reflection, diffusion, absorption, with a greater proportion of absorption on front and rear walls. Localization of the surround speaker is a function of the high frequencies heard by the listeners on the sides of the room.

This also happens at the cinema for patrons sitting in the seats at the sides of the theater. To reduce localization, the installer can either roll off the highs, turn down the side loudspeakers or elevate the speakers so that their tweeters fire over the heads of nearby listeners. This will allow ALL of the listeners in the seated area to hear a more uniform soundfield without the hotspotting typical of conventional loudspeaker topologies that listeners closest to a surround speaker often experience.

Dipole surrounds were conceived as a way to make a low-pass filtered, monophonic surround channel, more convincing in small rooms. Much was made of "diffusion" but in small "deadish" domestic rooms, there is no diffuse sound field, so the design intent of these type of speakers has more to do with marketing talk than a basis in reality.

With the advent of immersive surround sound hitting the home theater marketplace the de-correlated sounds can be radiated from several loudspeakers rather than concentrated in a few. Each speaker then becomes a less localizable source. Dipoles become even less relevant and indeed counterproductive in most cases. A shift towards bipole, monopole, or line source type speakers would seem to be the more appropriate course for the bed ear level fixed surround channels.

No question is more polarizing see what I did there? I have known and worked with many industry icons who strongly believe in dipoles or strongly believe in direct-radiating surround speakers. Jim Fosgate prefers direct-radiating, as does Dr. If you do your critical listening alone and in the money seat, you probably prefer monopoles. From his early days at Skywalker Ranch, Tony Grimani has always been an advocate of dipoles.

Historically, the greatest proponent of surround dipoles has been Tom Holman, who was the inventor of the Lucasfilm THX sound system. Tom is more responsible than anyone for the proliferation of dipole speakers used as surrounds.

These people are all formidable in the industry, and their opinions differ, to say the least. I consider myself fortunate to have known them all, and basked in the bright white light of their auras, all the while feeling inadequate. Excerpt from Legacy website: "Consistent with the new Atmos Dolby standards, Phantom avoids the phasey dipole effect of the early days of home theater.

In the early days of what was known as the Home THX program, we were taught by Tony Grimani and Tom Holman that in a typical home theater, dipole speakers best replicated the surround effect from many direct-radiating surround speakers in a much larger theater. The exceptional Stag Theater at Skywalker Ranch appeared to me in to have around twenty Boston Acoustics A70 speakers mounted high on the side and back walls for surround. I stand corrected if anyone can identify these surrounds as something different than I remember from that era.

I know that since then, the surround speakers in the Stag Theater have changed. My general advice to people who ask what type of surrounds to use is this: The smaller your room is and the more acoustically-controlled it is, and the more seats you have, the better dipoles will work. Personally, I am not especially a fan of dipole surrounds, but I use them in both of my theater systems because the rooms are not big, there are multiple seats, and the room acoustics are well-damped.

My dedicated theater is I have side dipoles mounted between the two rows of seating so there are still some directional cues and no one sits in the null. In my room, and in others like it, a direct-radiating surround speaker will hotspot. In a larger room; say, 4, cubic feet and up; bipoles or direct-radiating speakers can work very well. If you watch movies in a moderately-sized venue and there are only one or two seats, direct-radiating speakers can provide a stunning surround field.

I would recommend monopoles for a single listener who can position his speakers symmetrically and equidistant from the money seat. Are there tradeoffs? For rear surrounds, I would abide by the same basic guidelines, although many people prefer direct-radiating surrounds for rear speakers.

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. Dolby Atmos creates 3D, moving audio with an object-based listening experience. Audioholics has covered the new technology extensively since last year, and it requires, at the least, four additional speakers.

These speakers can be either ceiling-installed, or use specific Atmos-enabled surrounds placed on stands at head level with one array of driver s firing up towards the ceiling to reflect the effect, and another array of direct-radiating speakers aimed at the listeners.

I find it problematic that the implied suggestion by Dolby is that consumers should remove their de facto dipoles and replace them with surround speakers on stands. This is not a minor issue, and it affects a large proportion of people who have home theaters which feature dipole surrounds. Dolby Atmos 5. It seems that home theater has been migrating away from dipoles recently, though, and more towards bipole surrounds.

Just yesterday, I had a long conversation with the head of engineering at an American-manufactured speaker company, and he went as far as to say all their surround speakers are now shipped in a bipole configuration as a default.

Dipole configuration is available as a no-cost option. This company also manufacturers Atmos speakers, and when pressed about if he thought dipoles would work in an Atmos system, he hesitated in giving me a definitive answer.

He still believes dipoles may work better in a tight setup, which is what I have generally maintained. Because Atmos is a new home technology, and the implementation is still developing, and we can expect to have some definitive answers in the future when the dust settles. You'll always hear the optimum mix for your system, from stereo to 5.

And then there is always personal taste. Your seating configuration and room acoustics will also influence your decision. The interface between the speakers and the room is crucial, and the choice of speaker must be dependent upon all the variables. Confused about what AV Gear to buy or how to set it up?

12 of the world's most expensive loudspeakers


An important part of the concept of dispersion the lifelike radiation of sound from a source, either an instrument or a speaker is the idea of "imaging. Imaging is what we call our aural ability to pinpoint the location of specific elements of a soundscape. When we hear a saxophonist taking a solo on a small stage, we can close our eyes and our ears can locate the sound exactly where it originates, even among the other instruments on stage. When we hear a singer belting it out in a concert hall, we can close our eyes and our ears can sort through the ambient sounds of the expansive hall around us and pick out the location of the singer down there, center stage. It's important for a loudspeaker to deliver a wide, expansive, ambient-enhanced dispersion pattern. It does this by smoothing the crossover slopes between the midrange and high frequency driver responses, to avoid constricting "beaming" effects. But it's also important for a loudspeaker to present a clear and detailed high frequency performance, because it is those high frequency details that best cue our ears to a sound's originating location.

They say you can't put a price on happiness - but if we had all the money in the world to spend on our hi-fi set up, we reckon we'd be pretty content. We decided to do a little bit of detective work to find the most expensive speakers ever made - and we've been blown away by some of the price tags. The majority of the items on this list would be beyond the reach of most customers, but there's no harm in ogling some gigantic shiny speakers with crazy tech inside them. No doubt. You bet. So here's what we found in ascending order of outlay

A bipole or dipole speaker With proper set-up They also do a good job of conveying a sense of immersion and of disappearing as the apparent sound source. At most normal listening distances in most rooms, most of the sound that reaches your ears is reflected sound. And which is one is closer to what person would hear in e. Thanks, I understand what dipoles and bipoles are and that they are very different, and yet if my decades old memories are correct, maggies dipoles and my mirages bipoles produce a similar reaction in me.

Last August I was bitten by the bug of speaker building and HiFi sound. What an amazing hobby! It combines several disciplines such as electronics, acoustics, music, woodworking and art. All make such terrific synergy. The upcoming of programs like Speaker Workshop allow almost anyone to do a host of interesting acoustical experiments and fine tune speaker systems. Indeed, judging by the excellent web sites, the speaker building hobby is just booming.
