Radial Cab-Link Speaker Cabinet Combiner

Solidly constructed. Performs the useful task of combining two cabinets when the cabs have only one output. A welcome plus: the line-out jack, when your amp does not have one (which justifies the price). As mentioned by other reviews, note that this is not an impedance matcher, and therefore you have to make sure that the outgoing impedance is sustainable by your amp. To help you do that, schematics on the box itself clearly indicate how to proceed about connecting.

Radial may not have the sexiest pedals in the world, but what they make always works perfectly and lasts forever. I got this so I could run my PRRI into 2 16-ohm cabinets and IT WAS THE BEST DECISION I'VE EVER MADE! Sounds incredible!

This device does not do impedance matching. It is simply a shortcut to adding a second speaker out from your amp. In parallel mode it will affect impedance exactly like putting a Y adapter from your single speaker out in order to connect a second speaker (ie, connecting 2 speakers to a single output). Thus if connecting two 8 ohm speakers, you will have 4 ohm load and your amp must have a 4 ohm output tap. It also has the ability to connect speakers in series, where impedances are added. Thus connecting two 8 ohm speakers in series will produce 16 ohms resistance, and your amp must have a 16 ohm output.This device does nothing to solve the impedance changes that occur when connecting multiple speakers to a single output. You are still dependent on your amps expected output impedance. If you want to add a second speaker out, and your amp has the appropriate output impedance, then this will work great. Of course, many people attach multiple speakers to a single output all the time with no thought about impedance, but this is considered “abuse” of an amp. Solid state usually has no problem. Tubes are a different story.This does add a line level out from a speaker out. That alone might make it worth the price.

I've used this in a couple of situations, but it really shined during a gig when I ran my Joyo Zombie XL into two 16 ohm 2x12s and the dry out into a delay pedal which in turn ran into a combo. This is probably the most versatile piece of gear I've bought, and I liked it so much I bought another for backup.

Works as advertised without any issues. Great way to expand your cab section.

Radial is the “ Cats Meow” of all direct linking products etc...This is no exception!! Amazing quality and Canadian made, which I can be proud of!! I can’t wait to get their ABY box next..best value out there bar none.

I have this on a GM 40 pushing two 2x12. One with GB 25s the other with Anni 30s. I have other Radial gear and all of it is top notch. I have the line out going to my RME AI. Definitely could be used to send to FOH. -hth

I used this to link up 2 -8ohm speakers as 1 -16ohm for proper impedance to my amp
