Gallo Reference Strada Speakers and TR-3 Subwoofers

Anthony Gallo Acoustics has been developing and improving their spherical loudspeakers for more than 20 years. The new $1,998 per pair Reference Strada is the next generation, following the company’s very well received Reference 3.1 . The CDT3 tweeter is the exact same unit which is used in the new $5,995 Reference 3.5, and the dual 5” drivers with neodymium magnets are also found in the 3.5.

How to Dial In a Subwoofer

Here is how I dial in a sub. I do this procedure fairly often and it works very well. You can dial in a pair of subs in less than 10 minutes. It helps to have another person making the adjustments while you listen. We'll use the sub's level control and the sub's low pass filter (frequency) control.

We can usually live with sound that is missing most of the bass, and often do.

The Perfect Subwoofer

Note: I think I know what I'm doing here at the outset, so I have arrogantly titled this project "The Perfect Subwoofer". If the result is only an improvement over my previous reference, I'll be very happy. I also realize that perfect in one system might be anything but perfect in another. How is this possible?

Adjusting the controls on a subwoofer for best performance takes time and patience. It is always interesting to see ads for used subwoofers appear on the Web stating “only a week old” or “barely broken in”. These almost always identify a dissatisfied owner.
