bigjohn Posted September 7, 2011 Share Posted September 7, 2011 Big John just got a Big One. Got a few questions. Alex is away at the moment which is a shame... Anyone else shed any light? 1) I've found bits an' pieces saying this cab is "6 Ohm" rather than the expected 8 Ohm, because of the crossover. I'm a little concerned by this, as I'm hoping to run the cab off a amp that only goes down to 8 Ohm. 2) Does anyone know at what frequency the crossover point is? 3) Does it fit well on a standard Auralex Gramma Pad? ta for advice.

Mr. Foxen Posted September 7, 2011 Share Posted September 7, 2011 Pretty sure it is as 8 ohm as any other 8ohm cab. Close enough for most purposes. Think it was initally a case of when you actually measure impedance, the relevant parts of the plot give it a 6 ohm rating, but many other cabs marked 8ohm are equivalent amounts different. Maybe he altered the crossover design too. I think the Fearful cabs, developed in parallel cross over at around 800hz, guess similar for this.

Happy Jack Posted September 7, 2011 Share Posted September 7, 2011 I've used mine for two years with a variety of 8-Ohm amps. Nothing has blown up yet, but give me time. A Big One will [i][b]just [/b][/i]fit on a standard Gramma Pad but you'd best not be stacking anything heavy on top of it. My Big One has to carry the band PA (in a Gator 6U rack case) plus my own amp (either an OTB or a Line 6 Lowdown in a Gator 4U rack case) so I always use a Great Gramma Pad for the added stability and peace of mind.

warwickhunt Posted September 8, 2011 Share Posted September 8, 2011 Just out of interest which amp is it? Quote Link to comment Share on other sites More sharing options...

SVP-Pro, power amp and RANE DC24 Compressor/Limiter. Gramma pad is wider than The Big One, but 2cm more shallow... it's a poser.
