I picked up a pair of Kustom Deep End DE115H sealed 15" with horn recently and wanted to share some thoughts and details as there isn't really much info to be found currently. Sealed 15" cabinet and piezo tweeter No horn control though you can easily install a simple on/off SPDT toggle on the RED WIRE for the horn to disable it Light weight at around 50lbs with large side handles Removable 2" casters, plus huge rubber feet Appears to be a plywood baffle, but pressboard everything else Appears fairly well constructed - one brace in the back, some amount of padding, t-nuts for the speaker though the tweeter is directly screwed in through a gasket to seal it, no rattles or loose parts that I've seen. Appears to have no crossover (apparently piezo tweeters need none), and uses cheap plastic 1/4" jacks that are not sealed and should have a plug inserted to keep them from moving air and potentially whistling and buzzing. Overall a very nice cab for what it is. Has a lot of depth though not a lot of massive 40Hz sub-lows, has nice tight low end without being boomy like a lot of ported cabs are, is very smooth without any annoying high mid / high peaks even with the tweeter engaged. My only real complaints: Tweeter can generate a lot of audible "buzzing" noises when fed gainy sounds from your amp, overdrive, of fuzz pedals. I haven't cracked the case on this, but it's not a mechanical buzz from the sealed 15" vibrating it, you can remove the tweeter from the cab and it will still generate that buzzing noise which does sound like something loose but is just the horn. Turn the gain down (of FX off) and master volume wayyy up to feed it a cleaner signal and it goes away, seems related to grindy/tubey gain/harmonics. I haven't figured out a solution other than to disable the tweeter entirely which still sounds great (and is always preferred when pushing OD/fuzz IMO). No parallel Speakons, just parallel 1/4" though the jack board is traced for a parallel Speakon should you want to install one yourself. No horn defeat or L-Pad. Would've made troubleshooting the horn buzzing easier. However, you can simply install a switch yourself on the RED tweeter wire. Casters are small and always catch on every rug edge, etc. 3" MESA casters are the bomb diddy in comparison. One week after unboxing and they still have a noxious off-gassing odor to them. It's nasty. The two cabs stacked and pushed by my MESA 400+ definite start to fart out sooner than my GK 4x12 NEO cabinet. Or it could've been the nasty tweeter buzz, I'll need to retest. But overall I actually prefer the sound of the Kustoms over my GK. Tighter, smoother where the GK has more sub-lows, and high-mid peaks even with it's horn turned off. Guess those GK 12" NEOs push a lot of high mid/high end content?
