Granite base for 1.5's?
05/04/09 at 21:41:36
 
Any thoughts on what a 12x12x1/2" granite tile (about 6 pounds) placed under each speaker might do for the bass response of the 1.5's? My floor is not the most solid (basement below) and alot of energy is being absorbed and radiated through the floor. Thanks.

From what I have seen and heard of the 1.5, it might tighten up the response a bit. I do believe it would be an improvement, but I think you may find yourself messing with the distance from the bottom of the speaker to the peice of granite. If you can get that space just right, it is amazing how the bass response changes. It's a little change for the most part, but when it's right.......

Thanks for sharing that thought. I will try 3/4" granite (about 12 pounds) at some point and we'll see what happens.........

OK change of plans... I decided a granite plinth would probably create as many new resonance problems as it would solve so I decided to make something with natural tone properties and good dampening. I cut two squares out of Red Oak, beveled the edges and stained them. I put a thin cork mat under and on top of each plinth. Finally I removed the spike tips from the Radials and placed them directly on the cork surface. Wow, what a difference! Much less floor vibration and I believe EVERYTHING has improved. I did not expect this much of a change and so far it seems all positive. At least in my room this really seems like the way to go. I have attempted to attach a picture. --Greg
