Does carpet deaden the sound too much?

I also have plenty of LPs lining the side and rear walls.

I had speakers spiked on w2w carpet for many years. I just had carpet removed and hardwood floors refinish. I am now using Herbies Gliders with spiked speakers on the hardwood floors. It sounds more lively, open and detailed. I think its a big improvement. I am happy with the result.

@OP, there is a lot of nonsense being sprouted here through misunderstanding. Absorption in a room is necessary to reduce the time it takes sound to decay but the absorption needs to work over as wide a bandwidth as possible.

If sound is left to decay in an untreated room the result is smeared sound, congestion and loss of detail and nuance.

A carpet is, because of its limited thickness, a narrow-band absorber, and if you have wall to wall carpet as I see you do, then you will be absorbing only a limited frequency range and because there is so much carpet there will be information lost, resulting in an imbalanced sound.

Successful treatment is achieved by broad-band absorption.

@artemus_5 mentions finding hard floor and a rug helped.

@fatdaddy2 described a simple experiment which is a good idea. The sheets of plywood will negate some of the damage of wall to wall carpet. I favour a broad-band absorber on the ceiling preferable to carpet as a means of dealing with floor to ceiling absorption. This makes more sense if you consider that the human ear has evolved to allow for floor reflections.

Great, this is the area in which I need more information in order to make an informed decision. I know that my next move is on the ceiling, and your position of broadband absorption aligns well with what I have been reading.

How to implement that, for my particular needs, that I am very unsure of.
@lemonhaze - I’d like to know more about what you’ve done, how you went about it, researched it, implementation and resulting impressions please?
I can take it to DM (PM) if you’d prefer, as I am really interested, hopefully you're willing to share it?

 I've heard that an egg shaped room has perfect acoustics. Mind you won't be able to walk around, but you will have great sound.
