Line 6 PowerCab 112 Plus Speaker System (250 Watts, 1x12")

A 250W power amp, 12" hybrid driver and built-in speaker models with up to 128 presets make the PowerCab 112 Plus the perfect companion for your modeler.

The Line 6 Powercab 112 Plus is a 1x12 active speaker system that delivers an authentic "amp-in-the-room" playing experience when paired with any modeler. When set to Flat mode, you simply plug your modeler in and play; Powercab 112 Plus amplifies the sound of your presets as they are, much like a standard "FRFR" speaker system -- but with the response and feel of an actual guitar amplifier.

Now imagine having an empty 1x12 speaker cabinet that you can instantly load with any one of six classic speaker types just by pressing a button. Setting the Powercab 112 Plus to Speaker Modeling mode enables you to do just that -- virtually -- using a new technology developed by Line 6. Simply bypass the speaker cabinet models in your modeler's signal chain and let Powercab 112 Plus provide the sound and feel of playing through those classic speakers.

The Powercab 112 Plus guitar speaker system accomplishes this by combining a clean 250-watt power amplifier with a custom hybrid coaxial speaker. The speaker combines the range, clarity, and power-handling capabilities of a P.A. speaker, with the rapid transient response of a guitar speaker, in just the right measure to function optimally in both Flat and Speaker Modeling modes. And Powercab 112 Plus is loud, producing a room-filling 125dB SPL maximum volume.

In addition to sounding and responding like a true guitar cab, the Powercab 112 Plus guitar speaker system also looks like one. Sturdily constructed of plywood, with a unique curved read more back that adds rigidity and decreases weight, Powercab 112 Plus weighs a gig-friendly 36 pounds (16 kgs). And a flip-out kickstand allows it to be angled toward the performer, whether used in the backline or as a frontline monitor.

Compared to the standard PowerCab 112 model available separately, the PowerCab 112 Plus offers several powerful advanced features, such as a 2-inch LCD, 128 user preset locations, MIDI In/Out, AES/EBU and L6 LINK digital I/O, a multipurpose second input, and a USB audio interface. Loading up to 128 third-party speaker cabinet impulse responses (IRs) is also an option, allowing users even greater tone-crafting flexibility.

The Powercab 112 Plus guitar speaker system for modelers looks, sounds, and responds like a professional guitar amplifier, because that is essentially what it is. In Flat Mode, Powercab 112 Plus delivers a neutral frequency response from 70Hz to 20kHz with plenty of headroom. There is no need to adjust your modeler's settings—your presets will sound just the way you expect them to. But what most clearly differentiates the Powercab 112 Plus from other products is Speaker Modeling.


The sound of great amplifiers is due to the speaker as much as from the other components, yet until now no one has modeled an actual speaker driver alone, independently from the cabinet it happens to be loaded into. Line 6 has done just that by creating models of six classic and boutique speakers which drive a custom-designed hybrid coaxial loudspeaker. A lightweight cone and high-temperature 2" voice coil deliver the punch and dynamic response you expect from a guitar speaker, along with the wide range of a P.A. speaker. This design adds unparalleled authenticity to the speaker models, and consequently the sound of your amp modeler, preamp, or even your stompbox amp-simulator.


The Powercab 112 Plus features a highly efficient 250-watt power amplifier capable of producing up to 125dB Peak SPL—enough volume to fill a small club or medium-sized venue. And Powercab 112 Plus is constructed to withstand the rigors of the road, while also being compact and weighing a mere 36 pounds (16 kgs). There's also an XLR output featuring optimized microphone emulation for direct connection to a PA, and foldout kickstands facilitate angled backline placement or use as an angled floor monitor.


Powercab 112 Plus can load and store up to 128 third-party Impulse Responses, recallable as MIDI-controlled presets. These can then be customized using the free Powercab Edit software for macOS and Windows, available at


Although Powercab 112 Plus was engineered to deliver superb results with any modeler, it is the perfect sonic complement to Line 6 Helix guitar processors, completing the chain -- from guitar input to guitar speaker.

I just went back to Helix after using Mesa MKV and Friedman JJ amps. The band doesn’t play a lot of gigs that require miking up the guitars or using direct FOH, so the speaker I chose had to sound great on its own and not just something to monitor myself with. The last time I went down the FRFR road it didn’t work out very well. I know it’s not the boxes it’s me, but regardless I got tired of constantly trying to find the right IR or thinking I found one that sounded good at home only to have it sound like crap at band volume yada yada. When I was researching speakers for the Helix I heard a lot of great things about the Powercab so I thought I’d give it a shot. The speaker modeling is somewhat unique, and I thought it might be the shorter path to better tone for me. It arrived 2 days after I ordered and the set up was very easy. I had already decided to use L6 link instead of XLR because I wanted to remotely control the cab via the Helix and not have to set up MIDI. Out of the box it was still on an old software version and needed an upgrade to support the L6 Link remote control, but updating it only took a couple of minutes. Just hook it up to your computer with a usb cable and download and run Line6 Updater. 5 minutes later you are up on version 2. After that it was just plug the Link cable in and turn it on. I started with building a basic high gain patch with the Friedman model with no cab. I chose the Vintage model in the PC+ and immediately noticed that the boomy read more bass and shrill high end that I didn’t like with FRFR was not there. It sounded, well, more like a guitar amp! Did it sound exactly like my JJ running into a V30 cab? Probably not, but it sounded very good and that’s what I was after. I didn’t need to add in EQ blocks to ‘correct’ the sound either, the amp EQ sections are all that’s needed to tweak the tones I wanted. After playing with it for over a month and having a chance to hear it at band levels I can honestly say this is the best solution I’ve found for modeling. And yes, there is plenty of volume. There are 2 other guitarists in the band and the PC+ kept up fine with more to spare if needed. I would recommend the Powercab+ to anyone looking for a modeler speaker solution.

I’m very happy with the sound quality. It may not sound identical to the original speakers modeled but honestly I don’t have that good of an ear to know the difference. I do know my high gain and crunch patches with the Vintage or Green sound just like I want, and for clean-ish tones the Essex with a Vox amp does the job quite nicely. Whether it has the mythical “amp in the room” sound or not is going to be up to each user’s own ears. I will say it sounds more organic and amp-like than any FRFR I’ve used and leave it at that.

This has so many features it’s hard to list what I find most useful. Physical features like being fairly lightweight and having tiltback legs are certainly helpful to an old guy like me. The tiltback seems extreme but it works well and I don’t feel the need for an amp stand. MIDI or L6 link to remotely change cabinets with each patch is great, and with the L6 link it can easily be done within each patch. I also like that the L6 link runs audio and data. Why use 2 cables when you can to it all with one? The ability to use it as a standard FRFR to run IR is another cool feature and I like that if I need to I can go direct to FOH via through the PC+ and use a separate IR to FOH and speaker modeling in the cab. Lastly, this can be used with any modeler. You can send MIDI messages via standard 5 pin MIDI cable to change speakers and IR within patches from just about any modeling product. If something ever trumps the Helix, I’ll still have a great cab to pair it with.

Ease of Use
It’s incredibly easy to get good sounds. Turn the knob on the top until you get a speaker you like. The speaker modeling sounds great. I’ve dabbled with some of the IR’s and they sound great too. Some folks have complained that it doesn’t have enough volume but that’s not been the case with me. You will need to make sure the output levels on your modeler are properly set to get the most volume and avoid clipping. If you aren’t familiar with how to do this, I would suggest checking out YouTube videos by Jason Sadites or Steve Sterlacci on how to properly set patch levels. It’s super easy and mostly common sense, but something a lot of folks overlook. And don’t forget to include your solo boosts when setting levels!!

By all appearances it seems very well built and sturdy and has a quality feel. I know there are people using these on the road and that also says a lot about the build quality. It’s been tossed in and out of my trunk a few times now with minimal wear and tear showing. It would be nice if it was made of birch and covered with Tolex, but that would only add to the cost and weight. As it is the box is solid.

At first glance $799 seems expensive for a 1x12 cab. However, when you consider what it can do that others can’t and then compare it to other 1x12 FRFR that are $1,000 and up it starts becoming a better and better value. If you don’t need MIDI or remote speaker switching, then there’s also the standard Powercab that’s a couple hundred less. Sounds the same just not as many features.

Manufacturer Support
Over the years I’ve purchased quite a bit of Line6 gear and they have always provided me with great support. They have a very good user forum with plenty of knowledgeable and helpful people and Line6 also has reps in some of the larger gear forums. Line6 has a good history of product updates as well. The PC+ has already received an update with some additional features and I expect they will continue to update as needed. They seem to do a pretty good job of listening to their customers when it comes to requesting features etc.

The Wow Factor
Speaker modeling, FRFR, and IR all in one cab that sounds really good. That’s pretty wow to me! I think this will appeal to players like myself who use modeling and are looking for the best sound without a lot of fussing, or just plain don’t like the sound of an FRFR as much as a normal amp and cab.
