So I gambled on a used older MarkBass cab to pair with my my Thunderfunk 550B. I needed something bigger and higher wattage than what I was using with my Thunderfunk head. On a side note is it possible I got a Thunderfunk 550B that's been upgraded to 800 watt specifications? The dang thing is extremely powerful even with the bigger MB cab it pushes it hard at half way on the master volume. How would one tell if the amp has the upgrade? So I have been very critical of the MB heads as they seem to fall short in an 8 ohm load and the amps are at full power at halfway on the master. Other than that I really like them my favorite being the LMIII, I have owned a good number of their offerings. Anyway I had stayed away from the cabs due to all the negative comments but I find this cab works really well with the TF head, its the MarkBass 104HF 4x10. This one is a made in Italy cab with the B&C drivers in it and looks new. I realize both these items are out of being the latest "got to have" gear but I thought some might want to know this is a good pairing. The 104HF sets really well with the overall tonal characteristics of the TF head. Something I hadn't considered until starting to do some serious research into what would work with the TF. The lower zealous tweeter on the MB kind of goes with vibe the TF has going to start with. I guess my main point is make your own decisions bout what gear will work for you. So kudos to this particular MarkBass cab design it works quite well. Obligatory pic with it's cousins.
