Improving sub quality

Dear Mark: You have to have your subs really " anchor " to the floor with out any movement between the sub/spike and between spike/floor. You can improve your sub's sound reproduction if you put some " weight " at the top panel: 20-30 kgs.

The Aurios goes against the performance sub's ( floating ). Maybe Ipy thinks he had an improvement but is not, he had a heavy degradation on the music/sound reproduction at the low end.

Regards and enjoy the music.

Hi Ipy: I do intensive test over the Aurios ( both models ) and my subs: the first time that I use the Aurios I was delighted for what " a priori " was a huge improvement, over the time I perceived that something was wrong not only with the " quantity " of the bass but ( more important ) with the " quality " : no pitch control and very " soft " bass. So, I return to spikes to " see " what happen and spiked everything was really on target.

What happen with the Aurios ( floating ) and subs: for a sub can do its work it is a must that when the woofer had a foreward/rearward movements the " box " stay dead-movement like a big heavy stone because if the " box " moves with the woofer movement ( like in the Aurios ) the bass sound reproduction will have a high diminishing effect ( like you say ) that will be far from the reality. Ipy: try to imagine what happen with the woofer movement through an Aurios and you can have the right answer. My english is bad and I do a great effort to explain this subject but it is very dificult to me do that in a good shape: sorry.

I can remember a rave review of the Aurios by R. Harley ( I think ) using through a subwoofer. Right now , I know he was wrong.

Regards and enjoy the music.
