@buellrider97 Thank you for the information regarding vacuum tubes. Very good information.
I get no sense of you being off cognitively. You seem pretty sharp to me! It took me four tries to spell cognitively. lol.
Footers under new speakers
Hi , I’m seeking advice regarding footers and/or platforms under my speakers. I purchased Tekton Double Impact’s and have heavy shag carpet and padding over a cement slab floor. House is 35 years old, cement is thick and well cured. I’m from that old mindset of spikes into cement and I am looking for an improvement. I’ve looked online at Gaia footers and Herbie's Studded Giant Gliders. I emailed Herbie’s and specifically inquired about the studded gliders alone on the DI’s over carpet. I asked about stability and was told the speakers were “ heavy enough “. Unfortunately I just set up the DI’s temporarily to get a little break in time. They are without any footers upright on my carpet. At 115 lbs the speaker does about zero to compress the carpet. I understand weight Vs footprint is abysmal but they won’t even stand straight. I’ll probably put the spikes on for a bit until I formulate a plan. But my first concern is that Herbie’s gliders alone are not enough and due to the minimum cost of the speakers I am struggling with purchasing Gaia’s footers and footer spikes. The seismic stands look exceptional, but I’m trying to be frugal. So I’m looking for suggestions like, gliders or dots with or without spikes on wood / stone plinths spiked to the floor. My goal is to try some sort decoupling (Gliders / Springs / Dots) AND eliminate the need of having to rely on the carpet being compressed. And yes I have cheap speakers and seek a cheap solution, so I get that limitation. Unfortunately I can’t afford Tannoy’s or Fynes to compliment my 180 watt tube mono blocs for at least a year. Cheers , Mike B.

@buellrider97 I am trying to show there are ways to get much of what can be attained for much monies for a lot less. Is aesthetic the trade off, not necessome of the arily if a little extra thought went into the end design. I recently put a Link up to Barry Diament who is the Godfather of releasing the designs for some very common items seen today with large price tickets, but Barry's designs can be produced for very low Dollars. Barry's Footers would be great for Tier 3 and Tier 5 used in conjunction with a perforated wall material as the Tier 1, on the Speaker Base Support I am suggesting and regularly use. As I have a large range of Isolators I can play with the Sub Sub Plinth and Sub Plinth Separators and attenuate the end sound incrementally, but not substantially, as the Five Tiers does the Substantial Change when used as the whole structure. In your own case Tier 1 Separators are with lesser choices as other controls are needed in conjunction with being a support. |
@rodzilla47 +1 thanks, that is the exact link I intended to post and could'nt remember where saved it. |
Measure it accurately: I use an old unloved, unwanted tonearm and cartrige jury rigged so I can use it to measure vibrations. This is way more sensitive than any phone App! Just rest the stylus on the DUT and plug the output into a spare amp phono stage and measure the output with DVM. Isolation works best as has been described.
Newton’s 3rd law states: For every action there is an equal and opposite reaction, so yes there will be an alteration but will you hear it? Using Newton’s Law and considering a conversation I had with Max Townshend at the Premium Audio Show in Veldhoven, Holland in 2019 who has now sadly passed away, the old gentleman explained that say your speaker weighs 40Kg and the cone of your speaker weighs 40gm we find a weight ratio of 1:1000 which equates to 0.01dB You will not hear that. Consider the response of your room’s huge effect on your speaker output. Below Schroeder the room dominates. Fact. Even an acoustically treated room will have peaks and nulls and if not then you will measure peaks/nulls in the order of 12 to 15?dB. You gonna hear 0.01dB. Pffft What you will hear is a vastly improved sound when speakers are Isolated. |
