    I doubt that, but so much depends upon the construction and the loudspeaker .We did some work with Spiers and Robertson ( laboratory isolation) they measured my floor with music playing with a three plane accelerometer and there wasn’t that much vibration, not enough for audible resonance, it is an interesting subject.

    Euros 5600 is the recommended retail ,they have inched their way from Finland to Denmark, hopefully they will arrive soon. I am looking forward to hearing them, they seem to do everything right, bass reflex but properly implemented. We shall see, Keith

    You can make a Hi-fi work in any room, Keith

    I’ll measure the Gradients when they arrive and see exactly how much the cardioid response decreases bass output from the rear of the speaker. Keith

    Various material have different absorption co-efficients but mass and depth. The Smith device is incredible, the first time I heard it, I was shocked but that was three years ago... Keith

    The only method of complete soundproofing that I am aware of is to build a room within a room, with isolation between the two rooms, sound will propagate through anything that connects them. Speakers with cardioid bass can help, Gradient claim a substantial decrease of rear propagation. Keith

    Yes look at visco elastic material , or springs in a gasket, rolling air diaphragm designs will isolate structural borne vibration to an extent , but it is very difficult, almost impossible to sound proof a room. Keith

    I really like music but aural memory is short, your brain is extremely powerful and cognitive bias plays a huge role and measurements are much more reliable than your hearing. Keith

    I enjoy listening to favourite songs on the radio, does that mean my radio is a really good system? Keith

    Unfortunately ears aren’t very reliable. Keith

    The bass shouldn’t be, it is deep but not overbearing , again acoustic measurement would highlight exactly what is going on or you could use an online room mode calculator, https://amcoustics.com/tools/amroc?l=700&w=450&h=285&r60=0.6 to look at your room’s main axial modes. Keith

    REW is’ room EQ wizard ‘which is really comprehensive room measurement software and so much more. It can even simulate your room and suggest where the best possible positions for speakers and listener might be, it is always enlightening to ‘see’ your room’s response. If you measure , move listening position even a little, re-measure compare, it is really useful . And of course it tells you a lot about the loudspeaker’s response in your room. Keith

    We are discussing speaker placement , I presume ChemMan is going to place them somewhere, and exactly where the speakers and his listening seat is make a huge difference. Keith

    They don’t have DSP Tugs, they have sophisticated boundary filters that adjust the amount of bass output depending upon position, individually adjusted one speaker can be near a wall one in free space and both adjusted for perfect balance, the cardioid response through the upper bass/midrange also really helps. I wouldn’t persist with the car analogies they have no relevance whatsoever. Keith
