Anthony Goldie Posted December 22, 2018 Share Posted December 22, 2018 Was curious to hear your opinions on this subject and also how you have your sub set up position- is it sitting on the floor, spikes or and also any changes you had after the mods you made Link to comment Share on other sites More sharing options...
BAM Posted December 22, 2018 Share Posted December 22, 2018 I have installed SVS Subwoofer Isolation System which are a soft rubber feet. They reduce floor vibration which results in tighter bass. $120 for 4. Well worth it. Link to comment Share on other sites More sharing options...
hopefullguy Posted December 22, 2018 Share Posted December 22, 2018 hmm bought a pack of 4 washing machine anti vibration pads from bunnings for $5... is it off the floor if its at the back of a riser? there are many variations on google search as to having the sub actually raised of the floor by placing on a decoupling platform. i think it would depend on your room acoustics, the sub in question ie: front firing/ down firing, size, placement and your "perceived" improvement based on how much you are spending :-) 1 Link to comment Share on other sites More sharing options...

almikel Posted December 25, 2018 Share Posted December 25, 2018 subs should go where they sound best. I would always recommend de-coupling subs from room boundaries, but the smoothest bass requires experimentation for the room position where the sub works best. The easiest way to determine this is to place the sub at the listening position (where your ears would be), and measure the response with a microphone at each possible sub position...sounds hard but is way easier than moving the sub to each position Place the sub at the mic position that had the best response - which may not be on the floor...or whatever position best balances room aesthetics/ergonomics and smooth bass response...the position for best bass may not work aesthetically/ergonomically in the room. cheers mike 2 Link to comment Share on other sites More sharing options...
88hht Posted December 28, 2018 Share Posted December 28, 2018 spikes for carpet and rubber feet non slip for hard floor is what I tend to go with.... also if its a single sub then as mentioned above, place where it sounds best for seating position.... 1 Link to comment Share on other sites More sharing options...

Yeah, I do spikes through carpet onto the concrete floor which is set into mother earth. Rock solid, so to speak. Subs are just like real estate ... position position, position. 1 Link to comment Share on other sites More sharing options...
Anthony Goldie Posted December 29, 2018 Author Share Posted December 29, 2018 Yes that all makes sense Its a front firing 10 Richter thor bass reflex ive just got it sitting on the carpet -sounds like a bit of experimenting might be in order:-) Link to comment Share on other sites More sharing options...
krakatoa Posted January 1, 2019 Share Posted January 1, 2019 (edited) Subs should be positioned where they sound the best. For my room, the bass would diminish at my seated position. Moved the sub to many positions around the room, and the result was always poor. Plenty of bass when standing up, poor bass when seated. Eventually moved the sub up onto a bookcase, in the hallway. Not super bassy, but even accross the room, seated area. Standing waves are a *****, S. Edited January 1, 2019 by krakatoa typo 1 Link to comment Share on other sites More sharing options...
Nigel Posted January 2, 2019 Share Posted January 2, 2019 (edited) Krakatoa, I have fairly even bass in the listening chair, (which is out from the walls for flattest overall response). As soon as I get out of the chair, there is too much bass, if I go into a corner, even more. Nevertheless, in the listening chair, it is very nice. That is normal. Oh and because I can aurally locate my sub, because the Lowpass isn't steep enough, I have it directly behind the chair, against the wall, so the bass isn't pulled left or right. Tried 2 subs in various locations and the measurements were never as good as when I went back to 1. Edited January 2, 2019 by Nigel Link to comment Share on other sites More sharing options...

That is normal. agreed - the bass changes markedly when you move around the room as your ears move through the peaks and dips in the room caused by modal behaviour. The goal is to get the smoothest bass at the listening position/s. Getting the bass right for multiple seats is harder. If I have a friend over I typically let them sit in the sweet spot, and just for fun I'll often sit in the rear corner to listen to the elevated bass. cheers Mike Link to comment Share on other sites More sharing options...

I've never tried it without the blocks tbh. It's not state of the art of course but in a smallish listening room the bass sounds full and pretty controlled. I use the bamboo blocks for all my components so made sense to pop one under the sub 1 Link to comment Share on other sites More sharing options...

Raises it and easy to move around wheels/castors on a floor (not carpet) would be regarded as "coupled" to the floor, same as spikes, or sitting directly on the floor. At the wavelengths produced by a sub, the "raising" makes no difference. "Easy to move around" makes a lot of sense cheers Mike Link to comment Share on other sites More sharing options...
