Magnat Signature 505 Floorstanding Speaker

The Magnat Signature 505 speaker is a 3.5-way floorstanding model designed for a home audio system. Its bass-reflex enclosure houses four drivers that cover different frequency ranges. The specified 170 W RMS power handling and 4-8 ohm impedance help when selecting a suitable amplifier.

Driver system

The 6.5-inch bass-midrange driver reproduces two adjoining frequency regions. A separate 6.5-inch woofer handles the lower part of the spectrum. This configuration should not be confused with a system using two identical bass-midrange drivers.

High frequencies are reproduced by a 1.2-inch dome tweeter, supported by a 0.75-inch super tweeter. The three specified crossover frequencies indicate where the filters divide the signal between the different driver sections.

The bass-reflex design uses an enclosure port to support bass reproduction. Distance from the rear and side walls can affect bass output. Marking the initial position makes it easier to compare several placements from your usual listening seat.

Amplifier selection and connection

The amplifier should operate reliably with a 4-ohm load, as this is the lower limit of the stated impedance range. A higher power figure alone does not guarantee a suitable match. The loads supported by the amplifier and your listening volume also matter.

170 W RMS is the continuous power rating, while 300 W is the stated maximum power. Neither figure should be interpreted as a mandatory amplifier output. Increase the volume gradually and turn it down if you hear distortion.

The 92 dB sensitivity rating was measured with a 2.8 V signal at a distance of one metre. It is therefore most useful when compared with models measured under the same conditions. Sensitivity does not indicate the maximum possible volume.

Room placement

The 205 mm-wide cabinet requires relatively little horizontal space, but the speaker is wider when fitted with its spikes. Allow at least 286 mm of floor width. The overall depth of 332 mm also excludes any additional clearance required from the wall.

The spikes increase the height from 930 to 970 mm. Consider this when placing the speaker beside furniture or beneath low shelves. Begin with both stereo speakers at a similar distance from the listening position, then adjust their angle while listening for a stable central image.

Placing a bass-reflex speaker too close to a corner can reinforce part of the bass range. If the bass masks other frequencies, first increase the distance from the walls. In this situation, room acoustics matter more than small changes to the amplifier’s volume setting.

FAQ

What is this floorstanding speaker designed for?

It is designed for a home audio system with enough space for a speaker standing 970 mm high with its spikes installed. Four drivers cover the separate sections of the 3.5-way system.

What type of amplifier should I choose?

Choose an amplifier whose permitted speaker-load range supports 4-ohm models. Consider its supported impedance range rather than looking only at its power rating.

How should I begin adjusting its position in the room?

Start with equal distances from the listening position and leave some space from the walls. Then move the speakers in small steps, listening from the same position after each adjustment.

Why do the dimensions with spikes matter?

The spikes increase the overall width by 81 mm and the height by 40 mm. Clearance around furniture should therefore be assessed using the overall dimensions rather than the cabinet dimensions alone.

Does 300 W mean continuous power?

No. The specified continuous power rating is 170 W RMS. The 300 W figure is the maximum power rating, so the two values should not be treated as equivalent.
