I bought this cabinet as an extension speaker to my Gallien Kreuger MB1500 which I use for string bass. I needed to push out more volume and keep the sound of the instrument. It does this well and by placing it well away from my main amp allows my fellow musicians to hear me better. Double bass players do have serious problems with amplification on a budget and I would recommend trying this either as an extension or with an amp head for gigs that need a bit more but you don't want to DI. It is a very solid piece of equipment, ok it's a bit on the heavy side for carrying any distance,(17kg) and has an excellent finish. Thomann why not a cover for this, it would really benefit from it.
I had tried the 4x10 and this made me buy this little beast. The 410 was a problem for me moving it all around so i wanted something more lighter but with the same sound quality!! The aluminium speakers does give a punchy and soft bass sound!! great for gigs and rehearsal and home improvisation!
