環迴喇叭 Surround Speaker - Monopole, Dipole, Tripole ?

[jv8803]

如果比我簡多次我會簡四隻都係monopole

[Raymond Wan]

I am wondering on this too as some members said back surround should be Direct firing other than Dipole or Tripole so I have no surround or back surround yet but only the 3 pcs at front
Raymond hing,do u know what is the proper distance for the back surrround to King seat?is it same as front?

If you have walls on side & back, better use dipole or tripole surround for movie.

However, if you do not have the walls for reflection, then better use the monopole or tripole.



The placement of the back surround is usually at middle of the FL and C as well as between C and FR.

Anyway, if your AV Amp has the control on ASA (Advanced Speaker Array) for the back surround. You can set to match the placement.

我有個好大疑問!

好多人都話套 7.1 (或 5.1) 如果係同一系列的 speakers, 效果會最好. 但我睇岩果套, side 同 back surround 都係 monopole.

咁如果我將兩對 surround 轉左個 dipole 或 tripole speakers, 要用其他牌子.

咁到底應該犧牲邊樣呢? 要同系列既連貫性, 定要多向反射既好效果呢?

我個廳因為係客飯廳成長形, 所以應該夠大, 可以安置皇帝位響中間, back surround 就響 10尺後既飯廳果面牆, 咁單用 monopole 又係咪會差好多?

呢樣野已經煩左一排, 攪到遲遲都未敢扑鎚買 speakers.

Front + center better to be the same brand

呢個一定! 即係果 4 隻 surround 唔使?

I think 90% of all the sound comes from the front & centre.....if you can afford of course goes for the same brand for all suuround

[Raymond Wan]

For placement of the surround speakers, there are various ideas.

For past THX, the side surround is 90 degree.

For recent THX, the side surround can be 90 ~ 110 degree.

Raymond, your last sketch is a 9.1, looks interesting. Would the mid-range Amp like 4308 support 9.1 set up?

I have tried Monopole, Dipole & Tripole for my home system.

My home is symmetric rectangular with 4 equal side & back walls.

I find Tripole Surround (M&K MPS2525) and Tripole Back Surround (M&K MPS 1525) give the best results.

I believe the use of either monopole, dipole or tripole will depend on the layout of the listening environment as well as the preference of individual.

Due to my listening environment is also a rectangular with relatively long in length, so I also consider 7.4 or 9.4 setup.

I am not familiar with the 4308 so no idea whether it will support the 9.1.

I have sent enquiries to various overseas forum and I believe 7.1 is already good for most applications in normal home theatre.

Unless you have more than one row seat at your home, the use of 9.1 may not be necessary.

For my case, I will stick onto either 7.2 or 7.4.

The Surround Back (MPS1525) may be replaced by M&K Surround-250 (i.e. same as MPS2525) eventually.

I perfer monopole

especially in HK, relatively not big listening area

Dip/Tri may make the soundstage a bit confused provided that the distance between each surround is too close

just my 2 cents

from a deaf

From plenty of the feedback from overseas users, they will choose:

(1) Musical Program --> Monopole

(2) Movie --> Dipole (or Tripole <-- exclusive M&K design only)

I'll suggest for movie use monopole also

Using monopole may get satisfactory results and even better results than dipole in some cases.

Hence, everyone should not stick on the simple use on monopole, bipole, dipole, omnipole, tripole, .......

I suggest each individual to study their own home environment to find the best combinations of surround speakers to suit and match for the performance.

There may not have a Fixed Rule for mode of surround speakers.



The beauty of M&K Tripole speakers, you can select:
(1) Tripole
(2) Dipole
(3) Monopole

Hence, you can try each of the above modes and find which mode suit you best and stick on it.



M&K MPS2525 (Tripole)


M&K MPS1525 (Tripole)

[Raymond Wan]

Tripole(三極唔係三向喎)係唔係得M&K同B&W先有?

Monopole = "單極" 或 "正極"

Bipole = "雙極" --> " + " & " + "

Dipole = "雙偶極" --> " + " & " - "

Tripole = Dipole + Monopole = "雙偶極" + "單極" (是 M&K 的專利設計)





According to M&K, for Tripole, when “surround sound” was called for, the dipoles moved to front stage.

When a soundtrack demanded pinpoint accuracy, the direct radiators kicked in.

As movie scenes panned from back to front, there was good timbre matching with the Tripoles and front speakers, as high frequencies were right on, due in part to the direct radiators.

One of the downsides to using a dipole or bipole is some high frequency information is lost because of the 90° angle created by the speaker and listening position.

Using Tripoles will eliminate the potential problems of dipole & bipole.



Although Tripole seems to be perfect, some people still prefer to use monopole or dipole or bipole or combinations.

The choice is depending the taste of individual.

Try them out to see which type or combination suits you best.

I believe you need to fix the position of your "King Seat" first.

The "King Seat" is depending on the screen size and your best viewing distance.

For S150, there is no need to follow exactly the suggested angle by THX.

What you need to do is adjust the toe-in angle (FL & FR) and tilt-up angle (C) of the S150 such that the centre of speaker is pointing toward your fore head near ear level.

Once you fixed the "King Seat", determine the position of the SL & SR (90 ~ 110 degree).

At last, place the SBL & SBR at appropriate locations to suit.

I assume you have already had a pair of SS150 for SL & SR, there is no need to use SS150 for SBL & SBR if your budget is tight.

Although it is perfect to use SS150 as all the tweeters and woofers are the same for the entire system, you can still use slightly lower class to complete the Surround Back channels.

The Surround at side walls is more important than the Back Surround.

If setting properly, some home theatre with 5.1 is already very good.

You will get even better results with the addition 2 back surround speakers for 7.1 system.

Finally, calibrate the input level of each speaker with sound level meter and the speaker distance accordingly.
