room space


I have a living room in apartment with listening space of 4m (from listening coach to front wall where speaker stands) x 6m wide with the height of 3m.  I am planning to purchase a 2nd hand Dynaudio Contour 3.3. But I am afraid that such kind of not so large space, the bass might cause standing waves which make bass unclear or vibrating the floor which cause down floor inhabitants complain.  Do you have any idea for my condition? Or should  I buy a smaller one such as Contour 1.8 MK II? Tks. in advance.

One thing that would concern me is the height of the 3.3's woofers in that size room. When there are two woofers and their dimensions from the floor are approximately the same as the distance from the side walls, that tends to throw off the in-room response in the upper bass and into the midrange. 


There's a big difference between reading about something in a magazine or sales brochure (white paper) and doing it for real. 
You have a good sized room, but I agree with gs556. You may not get the best bass response.
From the review, another situation...

"Had I been able, I would have preferred sitting even farther from the speakers. At 11’, I felt as if I was looking up onto the soundstage, which manifested itself several feet above the floor. This didn’t seem at all unnatural, but I suspect that if I could have sat a little farther back from the tweeter, which is mounted 43" from the floor, the soundstage would have appeared even lower."

I liked these speakers very much when I auditioned them in a very well treated room, so with that said, if you can get a good deal it’s worth trying them. 
Terrific imaging, you may need to play with position to get deep bass.

"Whitepapers are not sales brochures. They are written by the technical/engineering groups, not the sales and marketing groups."

Pure BS. I have yet to see otherwise. The marketing department gets their hands on everything that comes into contact with the customer. What's the first thing you see on the "white papers" you reference? All the different logo's of brands owned by Harmon, oversized and highlighted in a big box. Its not necessary because the "scientist" clearly identifies who he is and who he works for.

Regardless of all that Bob, we're stopping this right here. I've read several of your posts and I've seen nothing written by you that can even remotely help someone looking for advice. You're the guy that read a bunch of crap and now you're an expert. You go around making definitive statements about components you've never seen or heard. Audio doesn't work like that. If you want people to take you seriously, stop talking and start learning.

You'll no doubt pretend you have no idea what I'm talking about, so I'll do this 1 time, and that's it. 

"Assuming you listen to music that covers the entire audio band and you want to hear the entire audio band, then there will be room effects in the lower midrange and bass regions."

You can't know that unless you have complete knowledge of the room and system. For all you know the bass may be fine and the treble could be off.

"Sure, you can pick speakers that drop off that region of the audio band, but then you miss the foundation of music."

Same answer as before. Without further info its just a random comment.

"Rather than spending so much money on larger main speakers, reallocate the funds to include smaller main speakers and one or two subwoofers. You'll end up with a full range speaker system and the potential for a smoother bass response."

Once again, nothing can be done without a lot more info. These products are not generic and 2 speakers of the same size may preform completely different from each other.

"Keep this in mind as well... We place main speakers in a room for their imaging and sound staging effects. It's unlikely that such locations will also yield the best bass response. That's why some main speakers employ builtin parametric equalizers, .e.g, Vandersteen Model 5."

WE do nothing of the sort. That may apply to you, but I guarantee I set speakers up very different from what you do.
