MartinLogan Revamps Grotto Line with Powerful Subwoofers
MartinLogan has revamped the Grotto line with new 12" and 15" subwoofers, each powered by 1kW amps and dual passive radiators for deeper, more powerful bass.
The new Grotto subs feature a significant upgrade from the older models, which were sealed 10” models with 250 to 300 watt amplifiers. The Grotto 12 measures 17.8" x 17.9" x 17.9" (45.2cm x 45.4cm x 45.4cm), while the Grotto 15 measures 20.5" x 21.8" x 21.8" (52.2cm x 55.4cm x 55.4cm).
MartinLogan has impressed us with their subwoofers in our recent reviews of the Dynamo 12 and Abyss 10.
The new refresh of the Dynamo and Abyss series was greatly improved over their predecessor subwoofer lines, and now MartinLogan is giving the same treatment to their Grotto series.
