hi everybody,

I got Monitor audio BX2, BX1 and BXFX with Yamaha 3067 AV receiver (centre and sub are coming next). Could could please advice how to place them?

Room is 5.5m x 3.5m. with corner sofa at the end of the room side to the wall. Look at attached image for current placement.

As BXFX has Di/Bi-pole switch and I'm thinking to put it on the walls parallel with listing position at the end of the sofa, and with 90 degrees with the wall with windows.

I can place BX1 on windowsills which is 1 feet above and 1 feet away from listeners ears. Also I could use Yamaha's presence and place these speakers in the front top corners as height speakers.

What do you think?

I found another speaker with a multi-pole design that is quite promising:

The Legacy Phantom HD

How important is it for the surround speakers to match the front and center? I have expensive fronts and center and the company does not make an on-wall surround. They are ribbon mids and ribbon tweets. Any suggestions for alternative speakers to use?

They don't need to match perfectly. I would try to match the tweeter size and material (don't mix horns and domes, fabric and aluminum) and try to keep the drivers around the same size and frequency response to get as close to voice matched as you can.

Nah. I've tried every possible configuration over the years, including identical satellites (NHT) and even near-matching towers (VAF Research DC7, a smaller version of my front DCX towers).

Personally, I found that having different-brand surrounds was a non-issue, so long as the sonic signature was a close enough match - especially these days with Audyssey EQ.

(Having an identical centre speaker, on the other hand... very important!)

Anyone have any insight on this? Also, will they work on a back wall that my couch is up against?

Yeah - I'm on my second set of these. Unless you have a very wimpy AVR buy them. They are very good at what they do.

You mean second pair as in you blew them or got a second cause you liked them? A Denon 3310 is the AVR, but seeing as these are 4ohm, hopefully they should work just fine, at least in the reviews they did on an average receiver ( i think).

I'm more concerned about how they will perform on the wall right behind me.

Can I get a recommendation for a good pair of diplole/bipole on-wall surround speakers to go with my Piega P10 fronts and coax center? The room is 15x15 that is open on 2 sides and has a cathedral 2 story open ceiling. It needs to have either a white or black finish. The Piega speakers use ribbon tweeters and midranges. My amps are stable for a 4ohm load and are rated at 200wpc 8ohm and 350wpc 4ohm.

Thanks in advance

Hi all,

Attached is a mockup of my living room. I'm trying to find the best surround option since I don't think 7.1 is an option and with the configuration there isn't really a sweet spot.

Would Bipoles or the before mentioned dual-monopoles be the best solution to diffuse the surround audio for everyone in the room?

Thanks - John

Yep, the attic above is all open, I was planning on running the wires that way as well. Would mono/di/bi - pole in ceiling speakers work best? Where would you stick then, above the seating or behind it?

The only con with in-ceiling would be the more "permanent" nature vs a tiny hole in the ceiling for speaker wire for wall mounted.

I have been trying to put together an idea for a 5.1 combo for small/mid sized rooms.

A wall-mounted Pinnacle QP-9 sound bar (or placed at the base of the TV) can be had on ebay and other places for under $500.

The surrounds can be any of the Mirage Omnipolar series speakers (floor standing towers or wall mountable bookshelf models).

Buy an affordable sub like one of the BIC subs for under $250.

That will give you a system that is discrete and will sound GREAT for around $1000. The titanium based tweeters on will be a ballpark match and with a good auto-tune up from a nice A/V receiver, the speakers should all sound pretty close. My next home theater will be using the Mirage omnipolar speakers as surrounds. Depending on the proximity and space available, I may end up using a nice LCR sound bar under big TV both wall mounted. I found the Pinnacle speakers have a titanium-based tweeter, so there is a good chance at similar character/voice between the speakers after an auto-calibration is run on an A/V receiver.

This setup will only be as dynamic and strong as your subwoofer choice. This speaker system will only work well in a room that is around 2000 cuft or less. If the room is larger, you'll need to look into higher efficiency speakers.

For room acoustic purposes, it's my opinion based on much research that ANY room being used for the purposes of sound reproduction NEEDS to be carpeted and furnished, and if it's a large enough room, it will need sound-absorbing wall treatments. If your room has tile, nothing will sound good. (At least, that has been my experience).

Anyone have a suggestion of a good surround speaker to pair with my Polk Monitor 70's and CS2? I am looking for better rear channel than the Polk monitor 30 are providing. I just made a really rough sketch of my room. The issue I have is that there are two columns that protrude from my rear wall and prevent optimal placement. One side of the room is also open. I am wondering if using dipole speakers could help get more presence in my rear channel. Also as it stand the rear speakers are elevated about 4 feet above ear level of the listener, but then are aimed down. I have run audyssey in case you were all wondering. My budget is no more than $300 for both rears.
Thanks

I have the fxi-a6 and absolutely love them, I bought them from the Polk eBay store and they look new with 2 years warranty.

Wanted to see if you had some suggestions. Take a look at the photo below.
I need to replace the in-wall direct firing speakers. Due to WAF, would like to keep with a in-wall design. Any suggestions here?

I'm using Focal 918's w/metal tweeters and a Speakercraft Center angled down to the listening position. The Onkyo PR-SC885 is using audyssey. I play 60% movies, 40% music

Couch is against the back wall. Rear Channels are 6 feet off the ground (6 feet to the bottom of each speaker) and Right Rear and Left Rear are 5 feet apart at the edges of the couch.
From my ear to the bottom of the current in-walls is 3 feet. The current in-walls with frame are 12" long.

Any help is greatly appreciated. (I used a Sony Camera with panorama to take the photo..which is why it looks a little strange)

Are there any good in-wall Bipole Speakers, that can be switched to Dipole? I assume you would have to re-run Audessey when you do the switch

I'm considering getting a BIC Acoustech 5.1 system, which incorporates the PL-66 surrounds (pictured at the bottom of my post).



My couch will be against the back wall and I'd like advice as to where I should put the surrounds? My thoughts were the side walls as I'm not sure having speakers right at my head that close, would be ideal. But if these should be on the back wall, at what height? The room is just under 8' high. Can someone help? Thanks.

I have dilemma similar to those you are experiencing. Seating position is along the back wall and cannot be changed. Some logic seems to be pointing towards dipole purchase with placement in line with the seating, but I have some remaining concerns about this side-wall placement so close to the back wall.

I have found it quite frustrating that every reference diagram is based on the premise that seating is in the center of a room, even though the reality for most of us is that we simply do not have the space for such an arrangement.

Honestly, audio setup in most cases is about compromise, either with budget, or with placement, or with size.

Sometimes it's all 3.

My advice, try a few different speakers before committing to one solution and see what you like best.

I don't think anyone mentioned the Emotiva ERD-1 which I've found to be a very good surround. My fronts are DIY and very different but still there is no problem with them having a different "signature."

I know there are a lot of "on-wall" solutions like the Emotiva, but I'm looking for an in-wall. With in-walls, its reall hard to "try out" products without ruining your walls. That's why I was asking if anyone has experience with any of the following. As a side not, I saw the pair of Atlantic Technologies IWS-30SR-P's going for $500 (retail is $1500)

Just to add another data point here I wanted to relay the gist of my conversation yesterday with a customer support specialist (technical fella) from Emotiva. I had called to express some concern about using ERD-1 (well thought of on-wall dipole/bipole surround speakers) in my application. This is a small room used for TV/movies/games with the seating all along the rear wall. Placement-wise, the speakers would have to be very close (within a foot) of the rear wall in order to get that row of seats in the correct null position. My concern was that the diffusion effect would get lost because of the speaker's proximity to the back wall. The Emotiva rep agreed without any reservation and instead recommended in-wall monopoles for this particular application.

I always treat vendor advice with skepticism, especially those cases where they point you to another, more expensive product. However, their in-wall speakers are half the price of the ERD-1 so that doesn't seem applicable here. I am inclined to accept this argument but would be interested in any other comments.

I ran across a pair of Fosgate Audionics Dipolar SD-180 THX surround speakers (John Dunlavy's design) I can't find any information on the rear jumper settings to put them in dual drive, dipole, source point. I contacted Fosgate Audionics and was told that they have no information or support for the speakers since they were manufactured before the ROFO purchase in 2000. Does anybody own a pair of these or know the jumper settings?

It's a real shame the Mirage Omniguide is being killed by the Klipsch Group as it's acoustic properties make it the BEST SURROUND available IMHO.

It creates a much more convincing rear channel than any dipole or bipole I've ever heard.

It's a shame no one at KG has any vision or creativity...

That omniguide in a wedge tri-pole configuration would theoretically make the best surround speaker I can think of.
