What is the Klipsch Heritage Active Crossover?

It is an active DSP crossover designed to serve as the electronic core of the Klipsch Jubilee Heritage system, dividing the audio signal before amplification.

What is the Klipsch Jubilee?

The Jubilee is a two way fully horn loaded Heritage loudspeaker system that uses an active DSP crossover with bi-amplification, which is what this unit provides.

Will this improve an existing passive Jubilee setup?

It is designed to enable the active, bi-amplified configuration of the Jubilee system rather than to sit alongside a passive network. Setup should follow the intended active topology.

Overview

The Klipschorn AK7 Active Crossover is a purpose built DSP crossover offered as an option with the Klipsch Klipschorn AK7. Rather than splitting the amplified signal inside the speaker with passive components, this unit divides the audio signal at line level, before amplification, so each horn section is fed by its own dedicated amplifier channel. The result is tighter driver control, lower distortion, and a coherent presentation. It is the same active DSP hardware Klipsch supplies with the Jubilee, running firmware that Roy Delgado tuned specifically for the Klipschorn AK7.

Active crossovers work by processing the source signal digitally, applying the exact crossover slopes, time alignment, and equalization that the loudspeaker designer specified. Because the filtering happens before power amplification, the amplifier no longer wrestles with reactive passive networks, and the drivers see a cleaner, more precisely shaped signal. This approach requires bi-amplification, meaning two amplifier channels per speaker, one for the horn loaded low frequency section and one for the horn loaded compression driver.

This crossover is intended for Klipschorn AK7 owners who want the fullest expression of the design. The firmware is tuned for this speaker specifically, so it is not a general purpose crossover for other loudspeakers. Klipsch offers a separate version for the La Scala AL6.

Designed For These Speakers

This active crossover is offered as an option with the speaker below. It splits the signal before amplification for tighter control and lower distortion, and it requires a dedicated amplifier channel for each horn section.

Klipsch Klipschorn AK7 This is the loudspeaker this version was tuned for, a three way fully horn loaded Heritage loudspeaker. The active crossover is an optional upgrade that replaces the passive network with line level DSP division and per horn amplification.
Klipschorn AK7 The fully horn loaded corner Klipschorn AK7 shares the Heritage design philosophy of very high sensitivity and horn loading, making it a natural reference companion in a Heritage focused system.
Klipsch La Scala AL6 The hand built La Scala AL6 is a fully horn loaded Heritage floorstander that suits listeners who want horn dynamics and efficiency in a room without corner placement.

Frequently Asked Questions

What is the Klipschorn AK7 Active Crossover?
It is an active DSP crossover offered as an option with the Klipsch Klipschorn AK7, dividing the audio signal at line level before amplification.

What does an active crossover actually do?
It splits the source signal into separate frequency bands at line level, before power amplification, so each driver receives a precisely shaped signal for tighter control and lower distortion.

How is this different from a passive crossover?
A passive crossover filters the signal after amplification using components inside the speaker, while this active crossover filters the signal before amplification, removing reactive networks from the amplifier's path.

Does this crossover require bi-amplification?
Yes. Active crossover operation requires two amplifier channels per speaker, one for the low frequency horn section and one for the compression driver horn.

Which speaker is this crossover designed for?
The Klipsch Klipschorn AK7. Klipsch builds two versions of this crossover, one for the Klipschorn AK7 and one for the La Scala AL6, identical in hardware but with different firmware.

Can I use this crossover with any loudspeaker?
No. It is a dedicated component tuned for the specific Klipsch Heritage system it was built for and is not a general purpose crossover.

What are the benefits of an active crossover for horn systems?
Precise time alignment, controlled crossover slopes, and cleaner power delivery let the horn loaded drivers perform with greater coherence and dynamic ease.

Why does removing the passive network help?
Passive networks present a reactive load to the amplifier and can introduce losses. Filtering before amplification lets each amplifier drive its driver directly for a cleaner result.

Do I need special amplifiers to use it?
You need bi-amplification, meaning enough amplifier channels to power each horn section of each speaker separately.

Is the voicing preset by Klipsch?
The DSP implements the crossover slopes, time alignment, and voicing specified by Klipsch engineers for the intended system.

Does this include amplifiers?
No. It is the crossover and processing stage. The amplification for bi-amplification is provided separately.

Is Klipsch an American company?
Yes. Klipsch was founded in 1946 by Paul W. Klipsch, and the Heritage line is hand built in Hope, Arkansas.

How does it relate to the Klipsch Jubilee?
It is the same active DSP hardware Klipsch supplies with the Jubilee. The difference is the firmware, which Klipsch designed specifically for the Klipschorn and La Scala.

How does horn loading relate to this crossover?
Klipsch horn loaded designs use Tractrix horns and very high sensitivity. The active crossover ensures the horn sections integrate seamlessly with precise filtering and alignment.

Can I pair the resulting system with tube amplifiers?
Klipsch horn loaded speakers are highly efficient and pair well with lower wattage amplifiers, though bi-amplification requirements and amplifier choice should be planned for the full system.

Is this part of the Heritage line?
Yes. It is part of the Klipsch Heritage program that includes hand built models such as the Klipschorn, La Scala, and Jubilee.

What warranty does it carry?
It carries a 2 year parts and labor warranty from Klipsch for the original owner when purchased through an authorized dealer.

Can I add this to a Klipschorn AK7 I already own?
Yes. It is sold as an optional upgrade for the Klipschorn AK7, moving the crossover from the passive network to line level DSP. You will need a dedicated amplifier channel for each horn section. Talk to us about matching amplification.

Is professional setup recommended?
Because active crossover operation involves bi-amplification and precise system integration, careful setup following Klipsch guidance is recommended for best results.
