The Grotto adds a servo circuit, a tad better cabinet and a little more power (250 vs. 200) but in the long run, I could not justify the price difference.
Compact Affordable Performance Every element of Dynamo, from driver to amplifier to crossover to cabinet, is meticulously designed and manufactured to our highest standard. The result is staggering low-frequency performance for a subwoofer of its size and price. And its versatility is second to none. Variable phase and low-pass crossover controls enable custom tailoring to any system and environment. Dynamo can also be quickly reconfigured for either down- or front-firing operation.
Drawing on seven years of dedicated research into driver, amplifier, cabinet, control, and systems technologies, Dynamo establishes new benchmarks for performance and versatility in a subwoofer of such compact dimensions and moderate price. It is user-configurable for either front- or down-firing operation. That capability together with flexible crossover controls ensures that Dynamo can deliver excellent bass from any location in your room. No other subwoofer in its class offers Dynamo's combination of bass extension, power, and detail.
