Magnat Signature Sub 730 A is an active subwoofer for audio systems that need dedicated bass reproduction. Its down-firing 12-inch driver and bass-reflex enclosure make use of the floor boundary. A 190 W RMS amplifier powers the driver, while the adjustable 40-120 Hz crossover helps integrate it with the main speakers. Phase adjustment from 0° to 180° allows the sound to be matched to the speaker layout.
Magnat Signature Sub 730 A is an active subwoofer designed to add dedicated bass reproduction to an audio system. It uses a single 12-inch bass driver powered by an integrated amplifier. Adjustable crossover and phase controls help integrate the subwoofer with the system’s main speakers.
Design and placement
The enclosure is a bass-reflex acoustic system with a down-firing driver. This design requires sufficient free space between the driver and the floor.
Place the subwoofer on a stable, level surface, and do not obstruct the space beneath it. A thick carpet can reduce the available clearance, so the area around the driver cone must remain unobstructed.
Moving the subwoofer closer to a wall or corner will often increase the perceived bass level. If the bass becomes boomy, move the enclosure farther away and listen again from the main seating position.
Connecting it to an audio system
As this is an active design, the driver is powered by an amplifier built into the enclosure. Choose an audio cable only after confirming that the connection types on the subwoofer and amplifier are compatible.
If the amplifier also controls the crossover point, adjust both crossover settings consistently. Widely separated settings can create a gap in the frequency transition or cause unnecessary overlap in the bass range.
Adjusting the crossover
The adjustable 40-120 Hz crossover determines the upper frequency up to which the subwoofer operates. A useful starting point is the lower limit of the main speakers’ frequency range.
Speakers with less low-frequency extension will generally require a higher crossover setting. Main speakers that reach farther into the bass range are usually better matched with a lower setting.
If the subwoofer’s location becomes easy to identify by ear, reduce the crossover frequency. If the transition between the subwoofer and main speakers lacks energy, increase it gradually.
Adjusting the phase
Phase adjustment from 0° to 180° helps align the output of the subwoofer with the main speakers. The appropriate value depends on their relative positions and the listening location.
Play a repeating passage with consistent bass and slowly adjust the phase. Keep the setting at which the transition sounds most even and the bass does not appear to drop away.
Power and frequency range
The 190 W RMS rating is the more useful indication of power during everyday operation. The 380 W maximum rating describes the highest stated power figure.
The specified 19-200 Hz frequency range covers deep bass and the transition into the operating range of the main speakers. The endpoints alone do not define either output level or how evenly the subwoofer performs across that range.
The final result is affected by room size, proximity to walls, and the listening position. Placement, crossover, and phase should therefore be adjusted as parts of the same setup process.

FAQ
Is this subwoofer suitable for music and films?
It is designed to provide dedicated bass reproduction in an audio system. For music, it supports the lowest instrumental registers; for films, it reproduces low-frequency effects.
How should I choose the correct audio cable?
First compare the connection types and labels on both devices. Choose a cable only after confirming that the signal connections on the subwoofer and amplifier match.
Does the 120 Hz setting always produce more bass?
No. This control changes the upper operating limit rather than simply increasing volume. Setting it too high can make the upper-bass region sound excessive.
Which phase setting is best?
There is no single correct value. It depends on speaker placement and the room. Evaluate phase adjustments from the main listening position.
Can the subwoofer be placed on a carpet?
Yes, provided the carpet does not obstruct the space beneath the down-firing driver. The enclosure must remain stable, and the driver area must be kept clear.
What does the 19 Hz lower limit mean in practice?
It is the specified lower endpoint of the frequency range, not a promise of equal output throughout the room. The audible result is strongly influenced by room acoustics.
