Hartke HD500 2x10 HyDrive Bass Combo Amplifier – 500W

Two 10-inch HyDrive speakers. Powerful Class D amplification. One complete bass rig built for rehearsal, studio and stage.

The Hartke HD500 is a professional 2x10 bass combo amplifier designed for bassists who want powerful performance, responsive speaker technology and flexible tone shaping without carrying a separate amplifier head and speaker cabinet.

At the heart of the HD500 are two 10" Hartke HyDrive paper/aluminum hybrid-cone speakers powered by an integrated lightweight Class D amplifier.

The HyDrive speaker architecture combines the warmth associated with paper speaker designs with the attack and definition of aluminum, giving players a versatile tonal foundation for everything from warm fingerstyle bass to articulate slap, pick-driven rock and modern effects-based sounds.

Add Hartke's selectable Shape circuit, 3-band EQ, XLR direct output, effects loop and approximately 35-lb design, and the HD500 becomes a versatile all-in-one bass amplifier for working musicians.

How Does the Hartke HD500 Work?

The HD500 combines both the bass amplifier and speaker cabinet in one enclosure.

That means you don't need a separate amplifier head to power it.

Simply connect your bass to the amplifier's input.

The built-in Class D amplifier increases the power of the instrument signal.

Use the EQ and Shape controls to dial in your sound.

The two 10" HyDrive speakers then reproduce the amplified bass signal.

Your basic setup becomes:

Bass Guitar → Hartke HD500

For live performance, the XLR direct output can also send a signal to a compatible mixing console or PA system.

Two 10" HyDrive Speakers

The HD500 features two 10-inch Hartke HyDrive speakers.

A 2x10 configuration offers an excellent balance between portability and substantial speaker area.

Two 10" drivers provide the responsive feel bassists often want for:

• Fingerstyle playing

• Slap bass

• Pick playing

• Funk

• Rock

• R&B

• Gospel

• Pop

• Jazz

• Blues

• Worship

• Modern effects-based bass

The dual-driver design gives the HD500 considerably more speaker area than a compact single-speaker practice amplifier while remaining far more portable than many large professional bass rigs.

What Is Hartke HyDrive Technology?

Hartke's HyDrive speaker technology combines paper and aluminum elements within the speaker cone.

Why combine two different materials?

Because each contributes different characteristics.

The paper portion helps provide warmth and roundness.

The aluminum portion contributes attack, punch and definition.

Together, the hybrid architecture is designed to give bassists a versatile sound that retains musical warmth without sacrificing clarity.

That makes the HD500 capable of adapting to a broad range of basses, playing techniques and musical styles.

Class D Amplification

The HD500 uses Class D amplifier technology.

Class D amplification allows substantial power to be incorporated into a relatively lightweight and portable amplifier design.

That helps make the HD500 practical for musicians who need enough output for serious rehearsal and performance applications without carrying an excessively heavy amplifier.

500-Watt Bass Amplifier

Hartke positions the HD500 as a 500-watt bass combo amplifier.

That gives working bassists a substantial amplification platform in an all-in-one enclosure.

Rather than assembling a separate amplifier head and speaker cabinet, the HD500 integrates the system into one portable package.

Plug in.

Dial in your tone.

And play.

Shape Your Bass Tone

The HD500 includes Hartke's selectable Shape circuit.

Engaging Shape applies a specialized EQ contour.

The variable Shape control then allows you to move the center of that contour across approximately:

100 Hz–900 Hz

This provides a quick way to dramatically alter the overall character of the amplifier.

Need to carve out a different midrange space?

Adjust Shape.

Want the bass to sit differently alongside guitars and drums?

Experiment with the contour.

Want to return to the amplifier's standard EQ response?

Disengage the Shape circuit.

3-Band EQ

The HD500 also provides dedicated:

Bass

Mid

Treble

controls.

This gives you a familiar way to tailor the amplifier to your instrument, playing style and room.

Increase the lows for additional weight.

Adjust the mids to change how the bass sits within the band.

Use the treble control to modify attack and upper-frequency definition.

Then combine those controls with the Shape circuit for even greater tonal flexibility.

XLR Direct Output

The HD500 includes an XLR direct output for integration with compatible professional audio systems.

This is especially useful during live performance.

Use the HD500 as your personal bass amplifier on stage while simultaneously sending a direct signal to the venue's mixing console.

That allows the front-of-house engineer to incorporate the bass into the main PA system while you retain your own amplifier sound on stage.

The direct output can also be useful in compatible studio and recording environments.

Effects Loop

An integrated effects loop provides another way to incorporate compatible external processing equipment into your bass rig.

This can be useful for:

• Compressors

• Multi-effects processors

• Modulation

• Delay

• Preamps

• Other compatible bass processing

The effects loop gives players additional signal-routing flexibility beyond placing every effect directly between the bass and amplifier input.

Built for Active & Passive Basses

The HD500 provides a straightforward amplification platform for a wide range of electric bass instruments.

Whether your instrument uses traditional passive electronics or an active onboard preamp, the amplifier's tone controls and Shape circuit give you substantial flexibility for dialing in the overall sound.

Approximately 35 Pounds

One of the HD500's biggest practical advantages is portability.

The entire combo weighs approximately:

35 lb / 15.9 kg

That's the amplifier and both 10" HyDrive speakers together.

For a working musician, that matters.

Move it from home to rehearsal.

Carry it into the venue.

Put it on stage.

Play the show.

Load it back into the vehicle.

A complete bass rig weighing around 35 pounds can make regular gigging considerably easier.

One Complete Bass Rig

A traditional bass setup can require several separate pieces:

Amplifier Head + Speaker Cabinet + Speaker Cable

The HD500 combines the amplification and speakers into one enclosure.

Your basic setup becomes:

Bass + Instrument Cable + HD500

That's less equipment to transport.

Less equipment to connect.

Less equipment to keep track of.

And potentially less setup time before the performance.

Great for Fingerstyle Bass

The dual 10" HyDrive speakers provide a responsive foundation for fingerstyle playing.

Dial in a warm, rounded sound for traditional bass lines or use the EQ and Shape circuit to bring additional definition forward when the arrangement calls for it.

Great for Slap Bass

Slap techniques depend heavily on transient response and articulation.

The HD500's 10" HyDrive speakers combine the responsiveness of a 10" driver with the upper-frequency definition of Hartke's hybrid-cone architecture.

Use the EQ and Shape controls to further tailor the percussive character of the instrument.

Great for Pick Playing

Rock and alternative bassists often need enough attack to maintain definition alongside electric guitars.

The HyDrive speakers and adjustable EQ provide a strong foundation for pick-driven bass sounds that need to remain present in a dense band mix.

Excellent for Effects-Based Bass

Modern bass rigs frequently incorporate:

• Compression

• Overdrive

• Distortion

• Octave

• Chorus

• Synth effects

• Delay

• Multi-effects processors

The HD500's effects loop and flexible tonal architecture make it a strong amplification platform for players building more elaborate bass systems.

Rehearsal, Studio & Stage

The HD500 isn't limited to one environment.

Rehearsal

Two 10" HyDrive speakers and powerful Class D amplification provide a serious platform for full-band rehearsals.

Recording

Use the amplifier's natural speaker sound, XLR direct output or an appropriate combination of recording techniques.

Live Performance

Use the HD500 as your stage amplifier while sending its direct output to a compatible PA system.

Home Playing

The relatively compact all-in-one design also makes the HD500 easier to manage than a large separate head-and-cabinet rig.

One amplifier can therefore cover several different parts of a bassist's workflow.
