Looking to grab a Rumble 500 separate head - but what is the difference ..really..between the Bassman Pro cabs and the Rumble cabs?
Looking at getting a 410 but with such a price difference between these 2 cabs..is the Rumble just "budget" or is the Pro series just that much better? ( like the old Nemesis vs Eden )
The Rumble cabs have a different response, and less punch at high levels. Tonewise, it comes down to what you prefer.
Durability and overload limits are the area where there's the biggest objective difference. The Bassman Pro cabs translate some of the weight loss from the Neo drivers into more robust construction. The Neo drivers also have better motors (voice coil size, magnet strength, etc.) so they sound more controlled, and stand up better to being driven hard.
The Rumble cabs were designed to work with the Rumble heads, which have an aggressive limiter to protect the matching cabs from overload.
My pro gear (G-K MB800 and AudioKinesis cab) is much less forgiving. The G-K head has a defeatable limiter, almost no high-passing, and over 1,000 watts peak output. The single 12 in my cab has almost double the RMS power rating of a Rumble 115 and far more headroom below 100Hz, yet I have to be careful if I don't want to rattle the voice coil against the back of the magnet. If I were to do that very often, I would soon be shopping for a replacement driver.
The Rumble cabs are a great fit with their intended audience- weekend warriors who generally have to carry their own gear, and have a limited budget. Durability isn't as much of an issue when you carefully load your own gear, vs having it hand-bombed into a truck by an assortment of roadies. And when you use them with a head that's comfortably below their maximum power rating, the drivers should last indefinitely.
