LATEST ADDITIONS

Q I have a modest home theater in my basement that I have been slowly upgrading over the last two decades. The only component I haven’t upgraded yet is my Polk Audio subwoofer since it was a pretty decent model when I purchased it 20 years ago. Would I benefit from upgrading to a new 12-inch sub? —Cal Rempel, via email

THE VERDICT
Upgrades in style and performance take MartinLogan's Motion series speakers to the next level, while its Dynamo 1600X subwoofer is a feature-packed beast.

Ask a car guy to identify any classic American car from the 1950s or 1960s, and most would be able to pin it down to the exact year of production. Back then, the auto companies would change up styling every year, even if the mechanical stuff under the sheet metal remained essentially unchanged. The problem with that approach is that tooling up to build new models every year gets really expensive, so these days most cars have a life cycle of a few years before an all-new generation is introduced. To keep these longer-lasting designs looking fresh, at some point in the life cycle they'll give the car what's known as a facelift, replacing a few key parts like the grille, taillights, and trim to lend it a new look.
