Bipoles vs Monopoles for 10' side surrounds

HI,

I have 10' on each side of MLP. However, there will be people sitting approximatly 4 to 5 feet away from the side surrounds. All my other surrounds are monopoles BUT none are at ear level.

If I run monopoles on the ear level side-surrounds will people get blasted in the ears? Would bipoles be a way to combat that and perhaps hit a neglected area of the room?

Here is some other TL;DR info if you're interested

I'm looking at the following two speakers + factoring in something I already own and was considering using:

Paradigm 25S

These are likely the best quality speaker with the worst WAF. Not too mention the forward facing monopole woofer scares me a bit. They are also the most expensive (2k for the pair) meaning I wouldn't be able to get them for 2 years. These would also be a perfect match for my fronts because they are the Prestige series BUT they would not match my rear surround.

These will have the best WAF. Secondly, the may be the most diffuse (given that they are ear level this may be important). They would be cost effective relative to allowing me to leave my current speakers upstairs


Paradigm Surround 1's

These would be the most cost effective because I already own them upstairs. However, this will really neuter my small upstairs 5.1 setup. They have a medium to low WAF given that they will be 4' off the ground at ear level on-wall. Unlike the 25s, nothing is pointing directly at the listener. Which may help the non-MLP issue.

My layout is as such

So bipoles or monopoles from 10' out, considering the non-MLP experience (i.e. 4' away from the ear level side-surround)

If bi-pole would the surround 1's, 25S's or the in-wall dual tweeter be preferred.

If monopole, I will likely go in-wall which will be similar cost to the dual tweeter.

G'day.

Did you end up using a bipole for your surround channels?

How did it go?

I'm very interested in what people have to say regarding this. I have Bipoles currently connected in my Atmos system, but I wonder if Monopoles would be better.

It's not installed yet. However, I went monopole for everything given the dolby recommendations and cost. I figured with a 7.2.4 system I don't need to disperse the sound too much.

I'll fill you in when I complete it.

I'll let you know once they're in. I'll have no frame of reference though. I'll only have experience with this set up. However, I'll be able to tell you if there's some ear blasting in the non-optimal viewing position.

4-5 feet should be fine as long as side array is NOT at ear level........................you are much better having your side array above ear level...........how much depends on vertical dispersion of your speaker. My side array tweeters are 24 inches above ear level and are 5.5 ft from outside chair.

Remember, Dolby white papers are based on their experience in professional cinemas..............Adam Petz an exceptional calibrator along with Tony Grimani from PMI have highly recommended having surrounds above ear level due to hotspotting.

even if my monopole side surrounds are 10' from MLP? The rear surrounds are going to be about 5.5" up in the air

Once again, location depends on the dispersion of your speaker....................no need to hit reference with side surrounds BTW. 10 ft is close to what my surrounds are, I'm at a little over 8-1/2 ft.

These are the ones I got: http://www.paradigm.com/products-cur...5-r/page=specs

Not sure if there's a spec for dispersion? The tough part is picking the spot prior to installing them to test the dispersion. I suppose putting them 5.5' in the air is not going to kill the effect vs 4'. Maybe I'll split the difference(ish) and go 5'

i was just about to post on your other thread. I have another one on here.

I did go with the monopoles (CI Pro P65) because that's what dolby recommended and it was cheaper. HOWEVER, I don't have the theater set up just yet so I haven't been able to test it.
