Hey guys, i come here to filosophy about the pro's and con's a speakers suspended.. I'm a BsC in photonics from origin but in ative for quite a few years now (different study direction) and most knowledge is degraded.. At his moment i'm building a high end speaker.., the lx mini designed by some one called linkwitz.. as the design is rather functional i am trying to redesign it a little but without degrading the quality of the sound. one of the eye sore's is the base. so while thinking about a way to redesign that i quickly bumped into the fact that any speaker standing on a floor is not such a good idea as the floor will start acting as a sound board (one floor more than another) so many solve this problem by increasing the weigh of the speakers and making this encrease weight stand on spikes so there will be more energy needed to get that setup to translate its fibration to the floor (sorry if i don't use the right terms, but i prosume you will get the gist) in the mean time i found the new 'invention' of bluetooth speakers being suspended on a magnetic field. so i started to think about this suspension and if this would be benefitial of sacraficial sound quality wise. this is the basic design. and the following are my thoughts.. please add or contradict where anyone thinks i might be going wrong. 1) i want to suspend it on 6 O-ring like rubber bands around and at the hight of the "rubber coupler" which sits on top of the white pvc pipe and which is the base of mounting the bass driver. this would place it well above center point of gravity. 2) the bass driver is mounted on a closed tube, so a closed system below the membrane. so this would mean it can only transfer approx. 1/2 of it's energy to the air outside the tube. 'causing a vibration in an axial direction to the bass tube. 3) the full-range driver's tube is open.. so the energy on both sides of the membrane can be translate to the surroundings. this would give a rotational movement around the axis is the suspension plane. and his is what concerns me the most. the movement will deminish the sound waves amplitude a little which can be caught-up by the amplifier probably without being noticed. but the axial movent will create a small doppler effect, changeing the sound. on the other hand. the energy is so small and the speaker itself has an inertia that has to be over won that by the time it moves to the signal the signal has changed. shifting the effect of the doppler over the sound waves. losing it's correlation. so my main thought about this is, will this theoretically alter the signal.. or not.. and ifso.. is there a design alteration one might think of the stop or counteract this. i know that experimenting with a standard sine wave would be my best option but in practice that is not an option for me. so i want to think things as well as i can over before i start.. kind regards Matthieu ps: oh yeah.. the natural frequency of the suspension should be below 20 Hz. no clue how to make sure of this but this.. this needs to be the case.
