Ask about replacement drivers, foam surrounds, lid latches and keeper plates, rubber feet, grilles and retainers, and cabinet gaskets. Supply is by enquiry; listing a part category does not confirm stock.

Ask for the origin and condition of the specific item. Historical Bose reference numbers identify parts in the source manual; they do not establish that an offered replacement is genuine, new or available.

Available speakers and controllers can be added to the cart, with quantities limited to stock. Online checkout is not open yet. You can prepare an enquiry to arrange purchase; no payment or reservation is taken automatically.

Our focus is speakers and parts, with minor services such as part identification, small cabinet fittings and cable or connector checks. Ask about your specific job before sending equipment.

Confirm the exact series, condition of all eight drivers, surrounds, grilles, cabinet, input panel, lids and fittings. Ask what testing has been carried out and whether the matching controller, stands or cables are included; do not assume accessories are supplied.

A passive professional PA loudspeaker using eight small full-range drivers in an articulated array. It needs a suitable amplifier and model-appropriate active equalization.

The full-range array covers the intended working band without a conventional woofer-to-tweeter crossover. This does not mean perfectly uniform response in every room or the absence of protection and processing circuits.

Bose’s term for its angled driver arrangement. Series II documentation specifies broad nominal coverage of 120° horizontally and 100° vertically; positioning and room reflections still matter.

The Series II reference specifies 14 kg (31 lb) per loudspeaker. Weight differs between generations and can change when a lid, mounting hardware or other accessories are included.

The published Series II dimensions are approximately 33 × 52 × 32 cm, height × width × depth. Other generations differ; check whether a measurement includes a transit cover or brackets.

The Series II reference specifies a nominal 120° horizontal by 100° vertical pattern. That is a loudspeaker specification, not a guarantee of even coverage in every room.

Check the exact cabinet and the manufacturer’s approved stand adapter. Do not assume a generic 35 mm top-hat fits an older 802. Mounting accessories and cabinet inserts vary.

The Series II reference gives 114 dB average and 123 dB peak. Other models and test methods differ; maximum output also depends on amplification, processing and operating conditions.

They can serve vocal and instrument reinforcement when correctly configured. Required output, room size and low-frequency content determine whether additional loudspeakers or subwoofers are appropriate.

They can be part of a DJ system, but bass level and programme material matter. A suitable subwoofer may be useful for bass-heavy material; use documented crossover and protection settings.

Surround construction varies by driver and revision, including replacements fitted during a speaker’s life. Inspect the actual drivers rather than assuming every Series II cabinet has the same surround material.

The transport-oriented versions use a detachable protective front cover. Not every later installed-sound version has the same lid arrangement, and lids are not assumed included in an advert.

Use the manufacturing label on the actual cabinet or controller. A Bose model name alone does not establish a country of manufacture for every production run.

Use the active equalization specified for your model. This may be provided by the matching controller or an appropriate DSP with verified settings. An arbitrary EQ setting is not a documented substitute.

It shapes the signal to produce the intended overall system response. The required filters and equalization are model-specific; a generic description of a bass-and-treble boost is not a complete setup prescription.

Normally between the mixer’s line-level output and the power amplifier’s input. Never feed an amplifier’s loudspeaker output into a line-level controller input.

Only when the mixer provides a suitable master insert or other correctly routed line-level path, with compatible levels and connections. A generic effects send/return is not automatically equivalent.

A 31-band graphic EQ alone is not a verified replacement for the specified system response and protection filters. Use the documented controller or an accurately configured supported processor.

Yes, if its settings implement the correct model-specific equalization, filtering and protection. Confirm the speaker generation and amplifier before selecting a preset.

The speaker will not have its intended system response. Turning up the amplifier or adding arbitrary EQ to compensate can create excessive demand; missing EQ alone does not prove a particular driver has failed.

This depends on the controller. Some provide outputs and operating modes for associated bass systems. Check the exact unit’s connection diagram; do not assume every output is a subwoofer output.

Check the published compatibility for the particular controller, speaker and operating mode. Neither universal compatibility nor universal incompatibility across all generations is a reliable rule.

Not necessarily for standalone use. Some compact controllers need a specific optional mounting kit to fit a 19-inch rack. Check the dimensions and correct rack accessories for the unit.

Check the actual switch label and controller manual. “Sharp” may describe filter behaviour in documentation rather than name a front-panel control. The supplied 802C photograph has low-frequency and high-frequency cut switches.

They vary. For example, the 1997 original/SMD 802C manual identifies balanced XLR inputs and unbalanced quarter-inch inputs. Connector shape alone does not establish how a circuit is balanced.

Possibly, using a suitable line-level distribution arrangement. Confirm the controller’s output drive capability, the amplifier input impedances and grounding; do not join amplifier outputs together.

Use the current manufacturer documentation for supported DSP software and speaker presets. A third-party plugin or downloaded curve should not be assumed to reproduce the required processing and protection.

Noise, low output or altered response can have several causes, including routing, cables and level settings. Compare the unit against its documented test procedure; symptoms alone do not identify a failed capacitor.

Boosting a frequency band increases the signal demand in that band and can reduce headroom. Correct filtering, amplifier limits and operating levels matter more than assuming one universal power multiplier.

The 1997 802C manual specifies 180 Hz in bi-amplified mode. Other controllers and system modes can differ, so use the relevant connection diagram and technical reference.

Alternative processors may be suitable only where their documented settings correctly implement the required speaker processing. A product described as “for 802” still needs its compatibility checked.

Follow the exact speaker’s amplifier recommendation and the amplifier’s load rating. For Series II, the cited sheet recommends 240–480 W. That recommendation does not remove the need for sensible levels and protection.

Only if the amplifier supports bridged operation into the connected load and the resulting power is appropriate. Bridging changes the amplifier’s load requirements; follow its manual.

Where the input connectors are documented as parallel, a second speaker cable can link to another cabinet. First confirm the resulting amplifier load, connector wiring and cable capacity.

Two nominal 8-ohm speakers connected in parallel present a nominal 4-ohm load. Connecting cabinets through parallel sockets does not create a series connection.

Potentially, with two nominal 8-ohm cabinets in parallel per channel, if the amplifier supports that nominal 4-ohm load and suitable operating power. “Standard stereo amplifier” alone is not a sufficient specification.

Choose the conductor cross-section for the cable length, power, load and acceptable loss. Use a purpose-made loudspeaker cable and the amplifier or system designer’s cable guidance rather than a universal length rule.

Use loudspeaker cable between an amplifier and a passive speaker. Typical instrument cables have a different construction and conductor capacity; they are not a substitute for a suitable speaker lead.

Where a lamp is part of the documented protection or impedance-control network, its resistance changes with heating. A lamp and a resettable polymer PTC are not automatically interchangeable components.

Possible causes include a protection circuit, amplifier limiting, damaged driver, poor connection or upstream signal fault. Reduce the level and check the signal chain; do not bypass protection to diagnose it.

Not directly with a normal low-impedance cabinet. A suitable, model-supported matching transformer arrangement is required. Do not assume that a transformer named for another Bose model fits.

Choose an amplifier for its documented output, supported load and suitability for the speaker system. Tube or solid-state construction alone does not prove that an amplifier is suitable or unsuitable.

Excessive voltage, sustained overload, inappropriate low-frequency content or clipping can damage drivers. A small amplifier is not inherently destructive, and a large one is not automatically safe.

Only if the mixer permits the correct processing to be placed before its power-amplifier stage. Never connect its speaker-level output to the controller. Consult the powered mixer’s routing diagram.

Neither is a universal safe choice. Use suitable amplifier power, correct EQ and filtering, and control the operating level. Avoid clipping and sustained overload regardless of the amplifier’s nominal rating.

Confirm the pin assignments in the exact cabinet and cable documentation. NL4 has four contacts, and modified equipment can use different wiring. Do not rely solely on a connector’s appearance.

Possibly, where the model supplies the required output and load capability. DSP features and speaker presets vary; do not assume that every PowerSpace or PowerMatch amplifier has the same processing built in.

Ageing foam surrounds can crumble, split or detach. Deterioration depends on the driver material and its environment, so there is no fixed service-life deadline that applies to every 802.

Inspect the surrounds using the correct grille-removal procedure for your model. Look for cracks, missing material or separation without pressing the cone or damaging the surround.

Re-foaming may be possible if the original driver is otherwise serviceable and a correctly sized/profiled surround is available. It will not repair every coil, magnet or basket fault.

It requires careful alignment, suitable materials and an assessment of the driver’s other faults. A kit of the same nominal diameter is not automatically correct. BOSEMAN’s current service focus is minor jobs and parts enquiries.

Use a model-specific parts reference and confirm the supplier’s item, condition and origin. BOSEMAN lists historical references, but catalogue-parts stock is currently 0; the listing does not promise an available replacement.

The documented original cabinet uses eight identical full-range drivers, but replacement history and later revisions must be checked. The 1979 manual describes series wiring, not a universal series-parallel network.

The original 1979 manual specifies 1 ohm per driver, eight in series for an 8-ohm cabinet. Do not apply that individual-driver specification to every later or modified system without checking its documentation.

A fault may show as an open circuit, distortion, rubbing or no acoustic output, but each symptom needs diagnosis. Do not force a cone inward or assume that any rubbing means a melted coil.

Possibly, if the replacement matches the required part revision, impedance, fit and polarity. Inspect the other drivers and confirm that the cabinet has not already been modified.

Possible causes include loose fittings, wiring contact, damaged cones, a rubbing coil or enclosure components. Locate the source at a modest level before choosing a replacement part.

Follow the exact model’s service procedure. The original 1979 instructions describe clinch nuts and a grille retainer, rather than a universal set of perimeter screws. Avoid forcing the frame.

Only using the preparation, coating and masking guidance appropriate to the exact enclosure and finish. Keep paint and solvents off drivers, connectors and moving parts; alterations can affect the original environmental performance.

Identify the exact jack, wiring and panel arrangement first. Access and replacement procedures vary. Incorrect polarity, insulation or wiring can create faults, so the connector must be matched to the model.

Check the source, routing, controller, amplifier and leads before assuming a cabinet fault. Protection parts, wiring and drivers can also fail. Use the relevant schematic and avoid bypassing protection.

Incorrect processing is one possibility, alongside room acoustics, placement, excessive bass settings or damaged components. A sound description by itself does not identify a single cause.

Follow the care instructions for that particular grille material. Do not soak a grille assembly indiscriminately or let water reach the drivers and electrical parts. Allow any permitted cleaning to dry fully before reassembly.

A replacement must match electrical, mechanical and acoustic requirements. An aftermarket item is not established as equivalent just because its size and nominal impedance match; confirm its specification and suitability.

With equipment disconnected, a resistance reading can help find an open or short, but it is not a full performance test. DC resistance differs from nominal impedance; there is no single pass value for every 802 revision.

Yes. Moisture can affect cone materials, wiring, contacts and other components, particularly where water is trapped or seals are damaged. A weather rating does not make a cabinet immune to deterioration.

Useful life depends on condition, environment, loading and repairs. Some older units remain serviceable for decades, but no lifespan or warranty can be inferred from age or the Bose 802 name alone.
