The "it's too much" rig
Regular sized ;-)
I swear it was chef or b string who told me that when using the older Rb models that biamp is ill advised. Something about the NEO driver and the amp. I feel like I'm going crazy now.
Well, my review may not get a 10.0 score, but at least it's somewhat realistic. I loathe "this is the best (insert gear here) ever!" reviews.
the older 800rb is a different biamp than the newer HMS biamps....
As Chef pointed out the 800RB is an adjustable Bi-amp with the highest crossover point being too low for any of the horn loaded cabs (be it NEO, RBH, SBX ect.) 400RB has never had any bi-amp or HMS. While the NEO212 II sounds aggressive up close the out front sound is smooth and very present the point where most cabs tend to lose projection and get swallowed.
Hi there, I am planning to buy a new amp, GK RB400 IV and I never had any GK head before, but i am afraid that head isn't loud enough for gigs..I have markbass club 121 cab (8ohms) and with it GK RB400 IV delivers only 120w..is it enoough for small gigs and sometimes big stages with PA support always? sorry for bad english, thanks in advance.
Its got enough power. would be the weak point but with pa support it shouldnt be an issue.
Currenlty I use markbass LMII, never more than 4/10( LMII delivers 350w at 8 Ohms) and that is quiet enough for my needs, I hope that GK could do the same job for me.
G-K conservatively rates their products. The limiting factor would be a single 12" cab, in real world bass guitar use the cab will probably top out at 150 to 175 watts input of bass guitar.
In short it will drive that cab pretty close to it's limits, if that is loud enough depends on the others playing in the band.
in like sin!!
I was doing some checking today to see what damage i had to one of my 212 cabinets,as it turns out i think i was just putting too much low end in them and they were starting to distort,which was surprising because i never had this happen before.Anyhow after doing some tweaking of the knobs,i couldn't get the cabinet to distort like it was before.I was checking the cabinet with my mb800 and decided to compare it to my other 212.What i noticed was one cabinet was a little louder than the other one.The one that was distorting before was not as loud as the other one.I know two guitars made the exact same way will not always sound the same,is this the case with cabinets too ?

You may have damaged the cab. BGM tests showed at 8 ohms 566 watts rms with burst power of 646 watts. 803 and 1020 watts at 4 ohms!
Well it wasn't a huge difference,but it was noticeable.Is there some sort of way or test i can do to check for any damage.Without the speakers distorting,i can't tell which one would be bad and i don't want to spend $360 for two new speakers if i don't have to.
A repair shop can perform the tests, not much you can do without the proper test equipment. Chances of the DCR (that you could measure with a handheld meter) are not good.
