The other day I was fiddling with my car radio in an attempt to find an interesting station, not an easy exercise in my end of the woods. I landed on a real estate broadcast. I’m not in the market to buy or sell property, but I stayed with it rather than dial while driving. My car doesn’t have one of those all-singing, all dancing, voice activated in-car entertainment systems—”Alexa, play soft jazz.”

The subject being discussed was what sort of home improvements homeowners were investing in these days. In the current environment it may seem odd that some folks are putting in swimming pools, adding bedrooms, and remodeling here and there. But if it keeps contractors in business and their workers employed I’m happy for them. One question asked of the commentator was if these upgrades included an uptick in home theater installations. Given the current (non) status of commercial movie theaters, this seemed logical. The answer given, however, was a definite no. With the ability to now watch and listen on portable devices such as smart phones and tablets, the responder claimed that some current home theater owners are even converting their entertainment spaces to home offices or other more pressing needs. Yuck.

The center channel speaker doesn’t often get the respect it deserves. To keep it slim enough to fit on a shelf, many manufacturers simply offer two-way center designs, laid out in a horizontal woofer-tweeter-woofer arrangement. Every experienced speaker engineer knows that this is the worst way to design any speaker, but cost cutters, marketing departments, and consumers who don’t know better (or don’t care) demand them.

"How big is the screen?"

A recent product announcement from Amazon touted the launch of a “subwoofer” to supplement the response of Amazon’s popular Echo vocal assistant. Presumably it will work with the even smaller Echo Dot as well. But for me it raised a couple of eyebrows.

Given that the low frequency response of an Echo alone probably doesn’t reproduce any useful output much lower than 100 Hz (admittedly an educated guess), the Echo Sub certainly can't hurt. But given its size and its 6-inch driver, there's no way that such a product it can be considered a subwoofer...
