Floorstanding loudspeakers — Mission QX-5 MKII

The QX-5 MKII is a floorstanding loudspeaker from Mission's QX range, positioned above the LX-4 MKII with a larger cabinet and lower impedance. Mission's QX range sits above the entry LX series, offering more developed cabinet construction and driver technology for a buyer wanting more scale from the brand's catalogue.

Position in line

It sits above the QX-4 MKII and near the ZX-3 in Mission's floorstanding hierarchy. As a step up from the LX range, the QX-5 MKII likely represents a genuine engineering advance in cabinet volume and driver complement, moving to a demanding 4 ohm nominal impedance that the more accessible LX range does not require.

Key specs that matter

Rated response is 32 Hz to 24 kHz, deeper than the LX-4 MKII's 45 Hz figure. Sensitivity is 90 dB into 4 ohms with a 30-200 W window. At 53.5 x 35.0 x 125.0 cm and 34 kg it is substantially larger than the LX-4 MKII, consistent with the deeper bass extension and higher sensitivity this model claims.

Sound and use context

Expect a fuller, deeper-reaching presentation than Mission's LX-series, consistent with the larger cabinet and 4 ohm load - a capable performer for a buyer who has outgrown the more accessible LX range's compact scale.

Pairing

The 90 dB sensitivity and 4 ohm load call for a mid-power amplifier with reasonable current delivery, worth confirming against the specific amplifier already owned given the more demanding impedance here compared with the LX range.

Alternatives

The QX-4 MKII sits below this model in Mission's QX range for a smaller room, worth considering if this model's considerable 125 cm height and 34 kg weight exceed what a specific space comfortably accommodates. Mission broader LX, QX and ZX ranges give buyers a clear upgrade path within the brand as room size grows, and a dealer demonstration comparing this model against the entry LX-4 MKII helps clarify exactly what the step up in tier and impedance buys for a specific room. A rigid, well-positioned base or spike set remains worthwhile even at this accessible price point. Overall this remains a capable step up from Mission accessible LX range for a larger room. Toe-in adjustment at the listening seat remains a free, worthwhile tweak once placement is finalised. A subwoofer should rarely be needed given this tower already genuine floorstander bass reach. A dealer visit remains the simplest way to compare current stock across Mission closely related current range.
