Meridian On-wall Installation Loudspeakers

For years, Meridian loudspeakers have been regarded as offering the highest performance available – the result of careful design, the highest-quality drivers and components, transparent crossovers and rigid, low-coloration enclosures in both Active and Digital Active designs.

Now we have paid the same level of attention to the design of loudspeakers for installation purposes, including in-wall, flush-mount and on-wall configurations. These offer full Meridian performance for systems where the use of floor-standing models is impossible or preferred.

Showing the 320 on-wall system in natural wood finish (also available in paintable white).

The 200 Series in-ceiling/wall design and the 300 Series of wall-mounting systems allow exceptional flexibility of configuration.

The 300 Series consists of three ultra-slimline systems for in-wall (surface grille), on-wall and flush-mount (completely hidden, eg behind wall coverings) applications, featuring 6.5in (165mm) metal-cone bass drivers, and a wide-dispersion horn-loaded ribbon tweeter for superb performance anywhere. Passive units feature built-in crossovers with bi-wire/bi-amp terminals, while Remote Active units are bi-amped with the G41 Powered Crossover/Amplifier.

The 320 includes a single bass driver and tweeter; the 330 adds an 8in (200mm) Auxiliary Bass Radiator (ABR); and the 350 features two bass drivers and two ABRs. A companion subwoofer will soon be available.

Rigid enclosures minimise wall and cavity excitation so you hear the speakers, and not wall resonances. A white fabric-covered low-resonance grille is included and the units feature a slim wood- or painted/paintable-finish cabinet.

Simple and convenient mounting hardware is provided.

In every case, Meridian installation loudspeakers deliver the performance of a stand-alone design in a discreet enclosure with minimal visual impact – and awesome power.

This document describes the 300 Series active and passive on-wall speakers to be driven by external amplification; in-wall and flush-mount active and passive configurations are also available and are detailed separately.

The A200Z in-ceiling speaker is a 2-way design with an 8in (200mm) bass driver, pivoting tweeter and is supplied without crossover. The unit may also be mounted into standard 4-inch deep stud walls.

Wall Speakers

The 300 Series consists of three sizes of ultra-slimline wall speakers, each offered in three mounting formats:

In-wall (surface grille) (“i” suffix, e.g. A320i);

Flush-mount (completely hidden, eg behind wall coverings) (“f” suffix, e.g. P330f);

On-wall (hangs on a wall) (“w” suffix, e.g. A350w)

The 320 model may be ceiling-mounted.

Each unit features 6.5in (165mm) bass drivers, and a wide-dispersion ribbon tweeter for superb performance anywhere.

Passive units incorporate a built-in crossover; Remote Active units include a G41 crossover module. A white cloth-covered grille is included with the on-wall products.

The 320 includes a single bass driver and tweeter; the 330 adds an 8in (200mm) Auxiliary Bass Radiator (ABR); and the 350 features two bass drivers and two ABRs. All three models are available for passive (‘P’ prefix) and active (‘A’ prefix) operation and for in-wall, flush-mount or on-wall installation. See opposite for on-wall system dimensions.

The 300 Series includes a companion subwoofer, and 300 Series units can also be used in conjunction with the 200 Series in-ceiling units.
