I have ProAc Studio 140's and have put large spikes (2 inches) on them and they sit on granite slabs. The spikes rest on shoes. Sound was greatly improved from the spikes just sitting on the carpet. The large spikes make a difference.
Down Firing Speaker Ports: Carpet vs Hard Surface
Calling for thoughts, experience, and/or technical of speaker port theory....
I have had, and still own several speaker models and subwoofers utilizing downward firing ports. In most cases, I have always had carpet to content with, and even though all of my speakers have had spikes, I've wondered on the ideal setup scenario. I have tried the following:
1) Granite tiles under the speaker spikes to get the speakers up and allow better air flow. 1a) tiles split to allow the port air to hit carpet. 1b) Tiles together to allow the ported air to hit a reflective surface., or 2) spikes into the carpet which lowers the speaker toward the carpet and somewhat lessons air flow.
The best results seems to be with the tiles only partially gapped.
Any Ported Speaker theorists out there?
Thanks in advance.
