The combination of the OBC410 and OBC115 cabinets is another major attraction.

The 4x10 provides the immediate punch, articulation and midrange definition required to cut through a band mix.

The 1x15 adds additional low-frequency depth and a fuller, more rounded response.

Together, they create an imposing six-driver bass system with excellent versatility for rock, blues, soul, funk and heavier musical styles.

The classic Orange appearance completes the package, making this stack an outstanding choice for musicians who appreciate traditional valve amplification and distinctive equipment.

Detailed Features & Benefits

Orange AD200 – Powerful All-Valve Bass Amplification

The Orange AD200 is a professional 200-watt valve bass amplifier designed to provide rich, harmonically complex tones and outstanding playing dynamics. Its Class A/B output stage delivers substantial low-frequency authority, while the short, straightforward signal path helps preserve the natural character of the instrument. The result is a powerful bass amplifier that responds expressively to changes in playing technique and gain settings.

Warm, Dynamic Valve Character

One of the AD200's greatest strengths is its ability to deliver natural compression and harmonic richness as the amplifier is driven harder. At lower gain settings, it produces warm, full-bodied bass sounds with excellent depth. Increasing the gain introduces additional grit, sustain and aggressive midrange character, making it particularly suitable for rock, blues and heavier music.

Straightforward Gain & Equalisation Controls

The AD200's traditional control layout places the emphasis on tone rather than complicated processing. The Gain control shapes the amplifier's input-stage character, while Bass, Middle and Treble controls allow the tonal balance to be adjusted. The Master Volume provides overall level adjustment, making it easy to develop sounds ranging from warm vintage bass to aggressive overdrive.

Dedicated Active & Passive Inputs

The AD200 provides separate instrument inputs for bass guitars with active and passive electronics. These allow different pickup output levels to be accommodated appropriately, making the amplifier suitable for traditional passive Precision and Jazz Bass designs as well as modern active instruments.

OBC410 – Powerful 4x10 Speaker Cabinet

The Orange OBC410 is a professional 4x10 cabinet designed to provide punchy low frequencies, articulate midrange and excellent projection. The original OBC410 specification features four Eminence Beta 10A speakers and a high-frequency horn, offering a balanced combination of powerful bass response and clear upper-frequency definition. Its substantial cabinet construction makes it particularly suitable for demanding live performance.

OBC410 High-Frequency Horn Control

The OBC410's high-frequency horn allows additional treble presence and articulation to be introduced when required. Its three-position attenuation control provides high, low and off settings, allowing the cabinet's upper-frequency response to be tailored to the instrument and musical style. This is particularly useful for slap bass, modern fingerstyle playing and bass sounds requiring additional attack.

OBC115 – Deep 15-Inch Bass Response

The Orange OBC115 complements the 4x10 cabinet with the fuller, rounded response associated with a 15-inch driver. The original model uses an Eminence Kappa 15 speaker in a robust, ported cabinet, providing substantial low-end reinforcement. It is particularly effective for players who want greater depth and warmth from their bass rig.

The Benefits of Combining 4x10 & 1x15 Cabinets

Using the OBC410 and OBC115 together provides the contrasting characteristics of two popular bass cabinet formats. The four 10-inch speakers deliver immediate attack and defined midrange, while the 15-inch speaker adds additional low-frequency weight. Together, they create a rich and substantial sound particularly appealing to bassists who want both punch and depth.

Professional Birch Plywood Construction

Orange's original OBC cabinets use high-density, 18mm birch plywood construction, designed to provide strength and controlled acoustic performance. Internal bracing and substantial cabinet hardware help the enclosures withstand the demands of regular transportation and live performance. Their distinctive skid runners also provide stable positioning and help couple the cabinets to the floor.

Classic Orange Stage Presence

The Orange AD200 and OBC speaker cabinets create one of the most recognisable bass amplification setups in rock music. The combination of traditional Orange styling, substantial cabinet dimensions and familiar control graphics gives the complete stack an impressive appearance. For musicians who value visual identity alongside sound, the rig offers unmistakable character.

Ideal for Bass Players Who Use Effects

The AD200 provides an excellent foundation for external bass effects. Overdrive, fuzz, compression, octave and modulation pedals can all be used to develop a wider selection of sounds. Its traditional valve response works particularly well with dynamic playing and gain-based effects, making it attractive to bassists who use pedalboards.

Designed for Live Performance

With 200 watts of valve output and a substantial six-driver speaker configuration, this stack is especially appealing for rehearsals and live performance. The OBC410 provides definition and projection, while the OBC115 contributes additional low-frequency presence. The result is a commanding bass rig suited to players who need substantial stage sound.

Who Is It For?

Rock Bassists: Powerful valve-driven tones with excellent low-end authority.

Classic Rock Players: Warm, expressive sounds and natural overdrive.

Stoner Rock & Doom Musicians: Thick, harmonically rich bass tones.

Blues Bassists: Responsive dynamics and traditional warmth.

Professional Gigging Musicians: A substantial rig designed for stage performance.

Recording Bassists: Rich valve character and flexible speaker options.

Orange Enthusiasts: A complete setup featuring one of the brand's most celebrated bass amplifiers.

Playing Styles & Applications

The Orange AD200 stack is particularly suited to classic rock, hard rock, stoner rock, doom, blues, alternative, indie, punk and heavier contemporary music.

The amplifier's warm, dynamic character works beautifully with passive bass guitars, while its active input makes it suitable for a variety of modern instruments.

The combination of the 4x10 and 1x15 cabinets provides powerful stage sound with excellent depth and midrange articulation.

For bassists who want natural valve overdrive, the AD200 offers the opportunity to introduce harmonic richness directly through the amplifier's gain structure.

How It Compares

Orange AD200 vs Orange Terror Bass

The Orange Terror Bass is designed to provide powerful bass amplification in a significantly more compact format, using a valve preamp with a solid-state output stage.

The AD200 is a fully valve-driven amplifier, delivering a different playing response and natural power-stage character.

Players who prioritise traditional all-valve tone may particularly appreciate the AD200, while musicians seeking portability may prefer the Terror Bass.

Orange AD200 vs Ampeg SVT

Both the Orange AD200 and Ampeg SVT are celebrated professional valve bass amplifiers.

The Ampeg SVT is particularly associated with powerful clean headroom and the classic Ampeg bass sound.

The AD200 offers its own distinctive Orange character, with warm lows, pronounced midrange and expressive gain response.

Both are appealing choices for musicians seeking traditional valve-driven bass amplification.

Orange OBC410 & OBC115 vs a Single Bass Cabinet

A single 4x10 cabinet provides strong projection and midrange definition, while a standalone 1x15 offers deeper, rounder low-frequency response.

Combining the two cabinets provides a broader speaker configuration that can deliver both characteristics together.

The choice between a full stack and a smaller setup depends on available space, transport requirements and desired stage sound.

Orange Amplification Heritage

Orange Amplification was founded in London in 1968, becoming one of the most recognisable British amplifier manufacturers.

The company's distinctive designs and powerful tones became closely associated with influential rock musicians throughout the following decades.

Orange developed a strong reputation for amplifiers capable of delivering rich harmonic character, powerful low frequencies and expressive overdrive.

The AD200 represents this philosophy in a professional all-valve bass amplifier, combining traditional circuitry with the output required for serious performance.

The OBC speaker cabinet range complements the amplifier with substantial construction, carefully selected speakers and classic Orange styling.

Together, the AD200, OBC410 and OBC115 form an imposing bass amplification system that reflects the company's longstanding commitment to powerful, characterful sound.

Power Requirements & Speaker Connections

The Orange AD200 is an all-valve amplifier head designed to operate from mains electricity.

A mains power lead is included with this stack.

Unlike a standalone effects pedal, the amplifier uses an internal power supply rather than an external DC adaptor.

Important Speaker Connection Information

The AD200 must be connected to a suitable speaker load whenever it is operated.

For an original OBC410 and OBC115, each rated at 8Ω, the two cabinets provide a combined 4Ω load when connected in parallel.

The appropriate configuration is:

• AD200 4Ω speaker output → OBC410 8Ω cabinet

• AD200 second 4Ω speaker output → OBC115 8Ω cabinet

Use suitable speaker cables, not conventional instrument leads.

Always check the impedance markings on the individual cabinets and amplifier before connecting the system.

Never operate the valve amplifier without a suitable speaker load connected.

If the labels or connections differ from the published specifications, consult a qualified amplifier technician before use.
