Laney Iron Heart IRT-X Powered Guitar Expansion Cab

Written by

Elliot Stent

The IRT-X Expansion Cab from the guys at Laney is a truly versatile tool for any guitar player. It is an active 200w powered speaker that can act as a expansion speaker for any guitar amp combo with speaker outs available, as a cabinet for your digital amplifier such as a Kemper or POD system, or as an on stage monitor. You can also use it as a 200w power amp to connect your POD or Kemper to your speaker cabinet

With a stereo effects loop, master volume, bass, and treble controls this is an extremely controllable system. DI out to the board with or without cabinet simulation and the option to run more than one of these at a time gives you so many options depending on what you need.

Here's what Laney say about the IRT-X


The key is - Electro- Mechanical Reactive Linking (ERL).

Unlike an extension cabinet - which sits after your output section, the IRT-X sits BETWEEN your amps output section and your amps speaker and cleverly mimics the response characteristics of your on-board speaker.

Unlike most guitar speakers, which are commonly, rolled off above 4Khz the IRT-X houses a high quality flat response 8" Driver and a 1"Compression Driver. As soon as you connect the IRT-X, YOUR guitar tone has the capability for far more highs and lows, which means more tone!

Used in its most straightforward application the IRT-X gives you more of YOUR tone! And since it's YOUR tone what better than to use it as your own personal guitar monitor on stage - every gigging musician has run into problems hearing themselves on stage.


The IRT-X gives YOU the solution to hearing YOUR own tone on stage.

Better tone that you can hear - it's a win-win situation!

But for the player who wants a little more - the IRT-X has a few tricks up its sleeve.


Guitar players love effects but sometimes they can get in the way of your tone - the best tone is the simplest tone.
The IRT-X houses a stereo FX loop!


Plug your effects into the IRT-X and you get all the benefit of your unadulterated guitar tone - with effects only in the IRT-X giving you a Wet/Dry set up.


The IRT-X can be scaled up to fit even the biggest rigs, with 2 IRT-X's you can run true W/D/W rigs with amazing sonic implications.


The IRT-X has a super compact footprint which means you can have a massive sound on even the smallest stage


Mic-ing the IRT-X is simple! The IRT-X comes equipped with an XLR DI out. Which can be sent directly to the PA and provides either a completely dry signal, or can be cabinet emulated - with or without FX!

Emulation options include Dry, 1×12 or 4×12, so there is no need to use a mic & stand, which on a tight stage is great news.

The on-board DI also means you get the same great tone night after night, venue after venue - no more relying on mic placements!


The use of hi tech modelling setups requires some specific considerations when it comes to amplification.

The IRT-X is ideally suited to pairing with a modelling processor or DSP based DAW package as the IRT-X has a completely flat, full range frequency response.

Meaning your carefully modelled signal path in not re-EQ'd during the amplification process.
