Such B&W DM 640 where my first good loudspeakers in 1992, still have them today in my little loudspeaker collection, from the days where B&W cared more about neutral measurements.Try DM640 or 640i (pictured) - previous model, for the ones in your first picture at the back. Drivers may be hard to find, let's hope it's something else.
Those curves look great. I have a rectangular room 17x15, which opens to the kitchen behind the MLP couch, on the long axis. Just got REW and Umik-1 microphone setup, but still learning. REW isn't showing base response as low as yours, near 20Hz. Is that with sub? Your EQ'd curves look great to me. what EQ is that ? Audyssey, Dirac etc on AVR or DSP? thx.
I don't have a sub in this room. I'm only using a miniDSP. My room opens to a long kitchen and formal dining room behind my love seat lol. I'm going to eventually put a sub behind my MLP recliner. Regarding your lower freq response, you could see if you have any cancellations you can correct by adjusting placement or adding bass traps to lower reflected waves. You also might have the headroom to just heavily boost your lower freq response, you may not know unless you try it. Before I added the very dense bass trap beside my right speaker I was getting cancellations out of my left speaker's bass response.
Hmmz. A suggestion regarding speakers and room placement. Those speakers are not in the optimal positions with them either side of the fireplace. Having them located either side of the chesterfield area would likely be better for imaging and sound. It might require a room furniture adjustment but it should be better sound.
Thanks for the suggestion and I totally agree but in my defense this livingroom was meant to be aesthetically pleasing and was why I chose these B&W speakers instead of choosing a better measuring pair of speakers. My upstairs HT is much better and centers around Revel F328bes. You're entirely right that properly spaced fronts sounds way better. The change just wouldn't fit the intended goal. I'll at least drop the tv down to the mantle soon.
Great looking speakers. Others here may bitch about the FR curves off the shelf but they definitely nailed the looks.
Go hard or go home...lol.
How far down are they at 19Hz?
Interesting. B&W’s advertised figures for the bass (19Hz in room) is met in your room. I expected something closer to the REL plot from the speaker!
I do not feel the need anymore and in any case, I would have to go for a much bigger/better one than the S5 to blend it properly. But to be honest, working with full range like 803d4 in a real room is much more difficult than to work with a smaller speakers and a sub. I think it would have been easier to work with 805d4 and a pair of subs. As mentioned, I am the way of acoustic treatment (with significant cost) to manage room mode issue excited by the 803d4. You do not see them on the curve but the first mode of the room in the 20-25Hz is crazy high in reverb time. Fortunately, the content in music in this range is quite unusual and thus it is not a big deal.
Hi Loysius, I see you placed your 803d4s very near to the front wall. That might explain the peak at 40Hz without room correction. Did you consider placing them farther from the front wall? That will change the frequency response without room correction and might improve imaging too.
