MartinLogan Grotto [4/24] Ntroduction

4 Introduction and Assembly

INTRODUCTION

Congratulations! You have invested in one of the

world's premier subwoofers.

The MartinLogan Grotto represents the extension of an inten-

sive, dedicated team research program directed toward

establishing a world class line of reference subwoofers using

leading-edge technology, without compromising durability,

reliability, craftsmanship or aesthetics.

The Grotto subwoofer uses a 10-inch high-excursion alu-

minum element driver to achieve deep, tight, well-defined

bass. Servo-control minimizes distortion. A proprietary

amplifier is used to drive the output stage with precision

and extremely high efficiency. Low-pass filtering and phase

control have been designed to make integrating the Grotto

subwoofer with MartinLogan and non-MartinLogan prod-

ucts both seamless and simple.

The materials in your new Grotto subwoofer are of the

highest quality and will provide years of enduring enjoy-

ment and deepening respect. The cabinetry is constructed

from the finest composite material for acoustical integrity

and is finished with our attractive custom coating.

This User's Manual will explain in detail the operation of

your Grotto subwoofer and the philosophy applied to its

design. A clear understanding will insure that you obtain

maximum performance and pleasure from this most exact-

ing subwoofer.
