Spikes or rubber feet.

I've got a nice pair of tower speakers that are new to me. They weigh 65 pounds each. They sit on hardwood floors. Currently they have hard rubber feet that screw into the bases. They also came with spikes. Spikes are a no-go for the hardwood floors but the spikes also come with metal disks that sit on the floor and that spikes sit on. There is a cone shaped dimple in the disk that the spike fits into.

Is there likely to be any appreciable benefit to the spikes sitting on disks compared to the hard rubber feet? They are obviously easier to move around with the rubber feet.

If you the spikes, put felt pads w/adhesive backing on the discs. You can then slide them on the hardwood for easy positioning.

@n80,

Rubber decouples, spikes couple.

Accelerometer readings indicate that there is far less vibration/resonance through the baffle if the speaker is decoupled.

It’s also possible that a loudspeaker may sound 'better balanced' despite greater baffle resonances but for greater resolution I’d prefer to use rubber feet to decouple.

I don’t think it’s anything to get too concerned about when it comes to well designed loudspeakers. Any decent designer would no doubt have worked very hard to reduce cabinet resonances to a minimum beforehand.

Agree, these are Aerial Acoustics. This is my second pair. The cabinets are rock solid. The rubber feet are from Aerial Acoustics. But, they are fairly hard.

I have Aerial 7t’s. When I first got my speakers home I called Aerial and talked to Michael Kelly about this very issue. He recommended that I use the spikes since my floor was not a slab but a floor with joists over a basement. Once I found a good spot for the speakers I put the spikes on and never looked back although they are on carpet.
