You will have to get it patented if this is a never thought of idea and it works.NSNO2021 wrote: ↑Mon Jun 27, 2022 8:26 pm I have been playing around with a totally fresh idea - well it's fresh to me and I can't find any evidence on Google of it. I think it will take me at least 6 months to get a decent prototype made but I am quite excited about it. Who would have thought I would have got the speaker stand bug ? Stu has a lot to answer for
I got to the stage in my experiments that I realised anything was worth trying because sometimes some out of the box thinking would work. Lots of stuff didn't mind you or a combination of design ideas were working against each other.
I now consider everything to be an extension of the speaker driver and so important to get right. The start is the driver itself but the way it is coupled to (or decoupled from) the enclosure makes a big difference. Then you have the enclosure itself which has a big bearing on any speakers outcome - material, construction, shape, design. I learned BIG lessons with my crappy chipboard efforts, it wasn't until the steel sphere came along that I realised exactly how crappy they were (but I always knew they were crap on some level ).
Then you have to consider how the enclosure is attached to the stand, unless you have built floorstanders in which case you have a load of other things to worry about . Coupling or decoupling between speaker and stand ? If I had drivers rigidly attached to their enclosure I would go for isolation to limit the stands sonic contribution.
Then there is the stand itself, so many things to think about. Material, shape, design, construction, weight. Light open frame stands look like they are a winner with cubes and I can go along with that. I do think if there is some isolation before we get to the stand then they become less important.
Isolating the stand from the floor with tubes worked wonders for me. My suspended timber floor was acting like a very crap extension of my speaker muddying everything. Then the whole room has to be thought about but we are already in obsessive audio mental health territory here and it is time for the straight jacket and padded room.
It is clear to me that anything vibrating apart from the driver's cone is a bad thing. The best way I could stop that was to sink that vibration into something that 'soaked it up'. What made things easier was the upward firing mid bass. I ended adhering a length of heavy brass bar directly on the magnet on the rear of the driver with a plate attached to the other end of the bar. The bottom of the spherical speaker enclosure is filled with sand. The brass bar extends into the sand by a few inches. This sand is the sink for the vibrations. At the other end my driver is isolated from the enclosure.
The result was hardly any vibration getting tk the steel sphere and along with the inner tube between speaker and floor, no vibration entering the floor. Totally blew my mind which is probably why I have had to take a rest from all this whilst my brain recovers. Slightly off topic this last bit but took the stand out of the equation in many respects.
