subwoofer,whats yours on?

[paulr]

Is it OK just to plonk it on the floor,or do stands exist and are they any good.?
Whats your on?

[Jase]

Currently its just sitting on the floor, no rubber feet etc. Last sub was on spikes.

Mine is on spikes but I have been advised to take them off and use the rubber feet supplied. Also being advised to place it on a concrete slab or paving stone which I also haven't got around to.

It isn't as bad as it sounds as the paving stone can be covered with a suitable fabric.

Ian.....does it really make a difference to the sound wether its on spikes or feet?........or was it the "advice" of a wife who doesnt want spikes in the carpet

Uncle Eric is not my wife and his view was in order to gain every last possible ounce of sound quality.

Whether or not it makes much difference in practice to ordinary mortals, I don't know as I have been too busy in the last couple of weeks to unscrew the spikes and find out.

I shall experiment then........thanks

I built my own so it's very firmly bolted to the base from a Linn Keltik speaker. The base is made from a very dense composite material, and this is spiked to the floor also.

The sub doesn't move much.

My sub is on spikes. Wish it wasn't as I put one of the buggers through my finger the other week moving it. Providing you don't drag it around your carpet should be OK. If Uncle Eric says to use rubber feet then that’s more than likely the best thing to do.

Mine are on spikes, on wood floor, little discs in between...

Mine came supplied with rubber feet. So thats what I'm using.

The spikes screw into the rubber feet, so there is more room underneath, also they dont wooble, I think they sound better this way...

Mine (Q100E) just sits on the carpet. Ironically, it is probably the only thing in my room that doesn't move around when watching films.

I had a noticable sound improvement after placing the sub onto concrete slab. One of the most cost efficient sound improving technique (got the slab at Homebase for £3.50).

However, I think this works much better on the smaller footprint sub. Difference on the larger sub were not so obvious.

Branxx - does your sub have feet or is it completely flat on the concrete slab?

I'm thinking of doing the same but i don't know whether to take the feet off of my sub for the best effect.

Personally, I've never liked spikes, for anything.
Spikes, no matter what, hard couple contact between surfaces. The fact that the actual contact area of the spikes are small is not relevent IMO. Hard contact, hence vibration transmision is always there.

I've always preffered rubber feet. Size of these feet depends very much on the weight and size of the equipment they support.

For example, I use 4 small rubber feet under my speaker stands followed by another four on the surface where the speakers sit. I do not use blu-tak. Blu-tak is plastic rather than elestic hence its compliance lessons over time. Rubber has an elastic nature which handles surface born and airborne vibrations far better.

Regarding Ians downward firing sub, this was firing onto a heavy carpet (not ideal). The concrete (or granite if you're rich) slab under a downward firer is a good idea, particularly if you have a hefty carpet underneath. The addition of a few slabs on top (if you don't mind what it looks like) is even better.
