A Guide to Bipolar, Dipolar, & Direct-Radiating Monopole Surround Speakers (PART I) - Page 19 - Blu-ray Forum

Goat1 · 02-28-2013, 04:26 PM

I'm running Martin Logan EM ESL's for mains,the matching C2 for center and Motion 4's for height speakers. The heights are nice for filling up the whole area with dialog,it really makes a big difference. I have Def Tech SR 8040 surrounds. I want to get the matching Martin Logan FX surrounds. My room is about 10 w X 25 L. So the side surrounds are probably 4' from my listening position. I probably have 10' behind me to the rear wall. I was thinking I should put monopoles back there. Maybe another pair of Motion 4's..

Thoughts?

I listen to 50% Music / 50% Movies. Room Dims24’ Long x 12’ Wide x 8’ Height. The listening position is against the entire long back wall as indicated with thick black line and brown circles - What mounting and speaker type would be preferred based on these options?
Option 1. Dipole Speakers mounted on side wall near corners in line with listeners?

Option 2: Monopole Speakers mounted in corners of room firing straight out?

Option 3. BiPole Type mounted on Side Wall or rear Wall but not behind the listeners as recommened due to my room limitations?

Any advice would be appreciated

how high should bipolar's be placed from the listening position?

About 2-3 feet higher than listening level.
I placed mine a little lower though due to pictures on wall

I'm sold on the dual BiPole/DiPole speaker type for non-directional sound just wondering where I should mount them for optimum performance since my listening position is along the entire rear wall and I can't mount them behind me as the drawing show for bipoles.

Perhaps I should just get monopole bookshelf speakers and mount in the corners of my room since I listen to 50% music. I dunno!

Advice Please?

Why can't you mount them behind you? If there's no wall, you could use stands

I think you'd like the sound of that much better than in the corners.

HifiRAT · 07-03-2013, 01:20 AM

I can mount them on the rear wall or side wall but I thought that the ideal location for BiPoles are a few feet behind your ears. In this case they would be above my ears but not behind b/c my couch sits against the rear wall.

So it's like my layout then. I personally love it. I tried my RT3 bookshelves in a couple different places trying to get the sound how I wanted it, but never could. After buying the bipole set, no regrets. Maybe its not the ideal positioning, but I have to work with what I have, so I'm good.

Billy13 · 07-03-2013, 01:37 AM

I'd say buy the bipole set you were mentioning and give it a try. I guarantee you'll like it, and if you ever change your layout or move, you'll have the right speakers and you won't have to have had bought two sets

I think I would have a problem with that because the wall is basically 6in to 12in behind me. So I'm not sure if the side walls will be better but hey, why not try it.

That would actually be ideal

As hard as we try to make the perfect Home Theater with the perfect sound system there is the room to contend with & the best way you can set things up

As Billy said he loves it that way so it is always worth a try & if you have to do some tinkering with placement

tommyboy81 · 07-05-2013, 01:26 AM

anyone had or have the Polk Audio FXI A4? How are those?

Goat1 · 07-05-2013, 02:51 AM

I was looking at the Fxi A6's. But I wonder if the dipole on them is a real dipole,being there isn't much of a null area and there is only one 6 1/2 " woofer.

Hi Big Daddy,

Recently i've relocated to a smaller room. I've setup the front 3 speakers but i'm not so sure about my PSB IMAGE S5 Bipole surrounds. My seating position at my ears is 1 ft from the back wall. i was wondering which would be a better option....

1. Install the Bipole surrounds on the side wall of my listening postion. In this installation the side of the Bipole speaker will touch the edge of the meeting of the side wall and back wall. so the surround will be exactly at the corner facing me at 90 degrees.

or...

2. Install the Bipole surrounds on the back wall. ? If you ask me to choose the 2nd option then how far apart the bipole speakers be ? the width of the room is 9 ft 3 inches and i sit right in the center.

Thanks in advance...

Regards,

Rana.
