Active speakers for a large room

Another vote for JBLs; very well behaved (good dispersion & off-axis response, etc) and reasonably priced for the performance level. The M3 series probably tallies with what you need

Thanks for your comments. Passive monitors are not really an option as it would mean changing most of the system. Power is not really a problem; the Genelecs are turned way down as it is. Speaker placement is pretty much fixed as it is, being ideal for movies and having already installed the in-wall cabling. The right far field monitor might work, perhaps a JBL. Is there a particular one which is designed to disperse the sound more? I think I owe you some further history. The P30 is a quality 5.2 channel processor which I had listened to for years in 5.2 mode for music. It gave me the ambience I was after, but when I tried the RME stereo DAC, there was a distinct improvement in the sound quality, even off axis, something that I am loathe to sacrifice. I think it would take big bucks to find a multi-channel processor to match it, so I am invested once again in stereo. My hope now is that greater, though not perfect, dispersion might be achieved by changing the two main speakers only. By concentrating my resources on just 2 speakers I can afford a significant upgrade. I am currently looking at a pair of PMC result6, which are a definite step up and might be classed as mid-field. Perhaps it is sacrilege, but I am also finding that extreme toe-in is helping, maybe because, in most parts of the room, the closest speaker is facing away and the far one is facing me. As ever, this exercise will be a compromise. Thanks again for your help; further comments appreciated.

sorry gregm; saw your post after i posted mine. i can´t find the M3. do you have a link?

@garbo, what I would suggest is consider adding a DAC.
As indicated the difference made an impression ...
If the P30 is working the way you want in the system build upon the structure in place.
And an MTM Array (Loudspeaker) config would still be a good suggestion.
Look at Eris E44 (Presonus) for example and see if it makes any sense to you.
Manufacturer Statement: "Eris E44: MTM design delivers the widest sweet spot in its class."
Please note that my example ( Eris E44 ) is not based on direct experience with the Monitor only that the MTM Array makes sense.
A suggestion for Toe In would be heck Yeah ... find the balance for the
’ Standing listening area ’ which should be crossed behind ( or at / or maybe not ) the seated listening position.
Toe In could be minimal so that the axis crosses well behind a first or second listening position.

rego, thanks for the suggestions. It was only worth getting a 2 channnel DAC as the others would have had to undergo a A-D-A conversion in the P30; not a good idea. In the end I have decided to buy the PMC speakers, as I got a good price and I know at least they will give me an excellent stereo system. They are supposed to have reasonably wide dispersion. Cheers
