Should I use Audiopoints under Aerial 10T spikes on hardwood floor?

Most speakers come with factory spikes and metal disks to put under them if you have wood floors. I have never actually used the disks, but I would not think there will be a really small difference. If you want the most performance consider Townshend seismic platforms… these will have a major impact… far beyond spikes and protect your floor.

• Townshend platforms (if you want to spend the money)
• Individual springs sized for the weight and damped with foam inside or thin heat shrink loosely applied outside
• Platinum Silicone footers by Hudson HiFi or Sound Addicted
• Sound Anchors stands specifically made for Aerial 10T, with their spikes and Cone Coasters

I owned the 10T's a few years back. Great speaker! I had the Sound Anchors stands specifically made for Aerial 10T, with their spikes and Cone Coasters. Highly recommended.

Nice speakers! I users to own them years ago & the they like & need lots of power especially in a big room if you play them loudly which they are very capable of doing. 
 

I don’t see many folks here mentioning this & I'm sure many won’t agree but whether you want to try to couple to or decouple your speakers from the floor really depends on the construction of the floor..If you have a very solid floor system like concrete slab on grade w/ ceramic tile or a very well made, very solid floor joist system ( unusual) , then coupling the speakers firmly w/ good quality spikes makes sense. If you have a more typical suspended floor w/ joists, plywood subfloor & wood or vinyl flooring on top ( over a basement or in the 2nd floor), then decoupling probably makes more sense to keep the floor from becoming one big resonating system which will likely muddy the bass & cause loss of detail, dynamics etc. 

In my opinion, the main reason for using spikes on any floor is to stop the speaker cabinet moving back when a dynamic driver moves forward, and vice versa.  It is Isaac Newton's law of action and reaction.  For this reason, IsoAcoustics makes isolation devices specifically for speakers.  These are more rigid in the fore-and-aft direction than sideways, when compared with the pucks they make for other components.  I mention this as a design philosophy, not a specific recommendation.

With big speakers like yours, any solid metal disk under a spike will be very effectively clamped by gravity!  Another of Newton's Laws ....
