What your choice speakers with spikes or speakers with a vibration isolation device?

That's what I remember about the company.

They have isolation platforms for floor standing speakers and subs as well as little ones for desk top speakers.

I'll repost if I figure out the name of the company (pretty certain I read comments/reviews here on A'Gon).

The best choice would depend upon the speakers used, the floor/substructure composition and (of course) your ears/preference.

List your gear/room/floor info in order to receive informed/meaningful opinions.

Interesting cables (never heard of them, but just went through their site).

Your listening room is approx. the same dimensions as mine (though probably better as it's a rectangle instead of the odd horseshoe I have).

Assume that bass it full/deep as it has been in my room with previous fuller range speakers (than my current tiny Tots:-).

My first thought would be to isolate the subs from the sprung floor, while in turn simply spiking the speakers to the same (Tekton supplies spikes I gather).

Forget the name of the fave sub isolation platforms (not expensive as I recall) and perhaps another member can fill in the blank.

Think the manufacturer may also offer isolation stands for small desktop monitors.

The other brand is Isoacoustics, which I've seen @ Guitar Center.

They have a sub platform that's $50-$60.

I found it:

Auralex SubDude ($70-$80).

I had confused it with another platform manufacturer who makes stands that look like square/rectangular scissor/baby gates.

Anyway, the SubDude is reviewed to be a good choice for suspended wood floors.

When I had wood floors in the 70's/80's I used carpet padding and horse hair pads under Rogers AB1's, but they probably only went down to 40 Hz (if that).
