Mission has occupied a distinctive place in British loudspeaker design since the late 1970s, building a reputation on a willingness to challenge convention when the physics justified it. The company has long prioritized musical coherence, time alignment between drivers, and cabinet designs that manage resonance rather than merely hiding it. The 700 is a direct descendant of that philosophy, reviving a name that carries genuine weight among enthusiasts while applying contemporary materials and driver engineering. What follows is a thorough look at how this two-way standmount is built and, more importantly, why each decision was made and what it does for the sound in your room.
What kind of speaker is the Mission 700?
The Mission 700 is a two-way vented-box (bass reflex) standmount loudspeaker. That means it uses two driver types (a mid-bass unit and a tweeter) and relies on a tuned port to extend low frequency output below the point where the woofer alone would begin to roll off. A two-way design keeps the signal path simple, with only a single crossover point where the audio band is split, which reduces the number of phase and integration compromises the designer has to juggle. The vented (reflex) alignment uses the air mass in the port and the compliance of the cabinet to resonate at a chosen frequency, reinforcing the bottom end. The practical payoff is greater low frequency extension and higher efficiency in the bass than a sealed box of the same size could achieve.
Why does the tweeter sit below the mid-bass driver?
The tweeter sits below the mid-bass driver because of Mission Inverted Driver Geometry, a signature approach the brand has used for decades to improve time alignment at the listening position. In a conventional speaker with the tweeter on top, the high frequencies (which travel a shorter physical path from a driver that is typically mounted flush) tend to arrive at your ears slightly ahead of the midrange and bass. By inverting the layout and placing the tweeter beneath the woofer, Mission arranges the acoustic centers so that the output from both drivers reaches a seated listener in closer time coincidence. The audible benefit is improved coherence through the critical crossover region, a more believable sense of a unified sound source, and cleaner reproduction of transients such as leading edges of notes and percussion.
This geometry assumes a typical seated listening height, so the 700 rewards proper stand placement that puts the drivers near ear level. The inversion is not a styling gimmick; it is a deliberate answer to a real timing problem.
The Drivers and Crossover
What is the bass driver made of and why?
The bass driver is a 6.5 inch mineral-loaded polypropylene cone. Polypropylene is a well understood cone material prized for its inherent self-damping, meaning it resists ringing and breaks up more gracefully than lighter, stiffer materials that can exhibit sharp resonant peaks. Loading the polypropylene with mineral content raises the stiffness of the cone without sacrificing that damping character, pushing any breakup modes higher in frequency and reducing their severity. In practice this yields a mid-bass unit that stays clean and controlled through the midrange it has to reproduce, with a warm but not woolly low end. A 6.5 inch diameter is a sensible choice for a standmount of this size, balancing bass output and cabinet volume against the need for good midrange dispersion.
What tweeter does the Mission 700 use?
The Mission 700 uses a 1.25 inch soft dome tweeter. The soft dome (typically a treated fabric) is chosen for its smooth, non-fatiguing high frequency character. Unlike hard metal domes, which store energy and release it as a resonant peak that usually sits just above the audible band, a well engineered soft dome tends to roll off more gently and self-damp its own break-up behavior. The 1.25 inch diameter is slightly larger than the common one inch dome, which lowers the resonant frequency of the tweeter and lets it operate comfortably down to the crossover point without strain. The result is treble that has extension and air while remaining forgiving of less than perfect recordings.
Where is the crossover point and what does that mean?
The crossover frequency is 3.0kHz, the point at which the signal is divided between the mid-bass driver and the tweeter. This is a fairly conventional crossover height for a two-way of this configuration, and it reflects a careful balance. Crossing over lower would ask the tweeter to handle more energy and higher excursion, risking distortion near its resonant frequency. Crossing over higher would force the 6.5 inch woofer to reproduce upper midrange content where its dispersion narrows and its cone may begin to break up. Placing the handover at 3.0kHz keeps each driver working within its comfortable band. Combined with the inverted geometry, this crossover region is where the 700 does much of its work to sound like a single, coherent source rather than two separate drivers.
Cabinet, Materials, and Build
How big is the Mission 700 and how much does it weigh?
The Mission 700 measures 20.08 x 10.24 x 11.50 inches (height by width by depth) and weighs 28.22 pounds each. Those figures are meaningful. At just over 20 inches tall it is a substantial standmount, tall enough to house a cabinet volume that supports the 6.5 inch driver and the reflex tuning. The weight of 28.22 pounds per speaker is significant for a box this size, and that mass is a good indicator of a well braced, appropriately dense enclosure. A heavy, inert cabinet is desirable because the walls should not vibrate along with the drivers; any energy stored and re-radiated by the panels smears detail and adds coloration. The heft here suggests the cabinet is doing its job of staying quiet so the drivers can be heard cleanly.
What finishes are available?
The Mission 700 is offered in Walnut or Black. The Walnut finish leans on the brand's traditional, warmly domestic aesthetic and suits rooms where the speaker should read as a piece of furniture, while the Black finish is more discreet and blends into a wider range of decor and equipment racks. Both are cosmetic choices with no effect on performance, so the decision is purely about how the speaker looks in your space.
Performance and System Integration
How efficient is the Mission 700 and how much power does it need?
The Mission 700 has a sensitivity of 86dB and a recommended amplifier power range of 25 to 150 watts. Sensitivity of 86dB is moderate, typical of a well behaved standmount, and it means the speaker converts a given amount of amplifier power into a moderate sound level. Speakers in this range benefit from an amplifier with real current delivery rather than one operating at the bottom of its capability. The recommended range tells you the design is happy with as little as 25 watts for modest listening levels in a small to medium room, while comfortably accepting up to 150 watts for larger rooms or higher volumes with dynamic headroom to spare. Staying within that window protects the drivers while ensuring the speaker is properly driven.
What does the impedance rating tell you about amplifier matching?
The Mission 700 has a nominal impedance of 8 ohms with a minimum of 5.2 ohms. Nominal impedance is a rough average of the electrical load the speaker presents across the frequency range, and 8 ohms is a friendly, easy figure that most amplifiers handle without difficulty. The more revealing number is the 5.2 ohm minimum, which is the lowest dip the impedance reaches at some point in the band. Because 5.2 ohms is not a severe dip, the 700 does not demand an exotic, high current amplifier to remain stable. Practically, this means the speaker will pair well with a wide range of integrated amplifiers and receivers without them running into protective current limiting or thermal stress.
How low does the Mission 700 play, and how loud?
The Mission 700 has a stated frequency response of 45Hz to 20kHz, with bass extension reaching down to 38Hz and a peak SPL of 106dB. The 45Hz to 20kHz figure describes the usable band where the speaker maintains its intended balance, reaching to the top of human hearing at the treble end. The 38Hz bass extension figure indicates how far the reflex-loaded woofer reaches into the low bass before falling away, which is genuinely deep for a standmount and reflects the effectiveness of the port tuning. That lower reach means most musical bass lines, kick drums, and the fundamentals of many instruments arrive with weight and body, often without demanding a subwoofer. The 106dB peak SPL is the maximum short term level the speaker can produce, which is more than sufficient for lifelike dynamics in a typical listening room.
How should you place and integrate the Mission 700 in a system?
Because the 700 is a rear or front vented reflex standmount that relies on Inverted Driver Geometry for time alignment, placement matters more than average. Mount them on rigid stands that bring the drivers close to ear height at your listening position so the time alignment lands as intended. Give the port room to breathe by keeping the speakers off boundaries somewhat; positioning too close to a rear wall will reinforce the low end from the reflex tuning and can thicken the bass. Toe the speakers toward the listening seat to sharpen the central image and lock in the coherence the driver layout is designed to deliver. As a two-way standmount with real bass extension, the 700 works beautifully as the front pair of a stereo system and integrates cleanly into a system built entirely around Mission components.
Where the 700 Sits in the Mission Line
Who is the Mission 700 for?
The Mission 700 is aimed at the listener who wants a full range, coherent standmount that honors Mission's engineering heritage while using current materials and driver technology. It revives one of the names most associated with the brand's identity, and it carries forward the defining Inverted Driver Geometry that separates Mission's approach from most of its peers. Within a Mission-based system it functions as a serious standmount capable of anchoring a high quality two channel setup, offering the time coherence and musical warmth the brand is known for, in a cabinet built to stay out of the way of the music. For an experienced enthusiast who values design decisions grounded in acoustic reasoning rather than fashion, the 700 is a thoroughly considered piece of engineering.
