I was amazed by what my 12/6 Alpha did in rehearsal situations with a pretty loud bunch of gang. Bear in mind, I have 900 watts at my disposal, but.... I suspect that my 15/6 will see very limited action. For me, if a 12/6 with some juice doesn't do it with a band, then they're too effen loud. :hiding:

Of course, I'm not talking about carrying a medium to large venue or anything like that- just about relative volume in a smallish space. YMMV, IMHO and other such....

My 12/6 is awesome and I don't have a lot of power....Yet. I haven't even used my 12/sub with it. Next Saturday playing an outdoor stage will be the 1st time for the full set-up.

Just did a festival show with my 15/6 and 15/sub and bridged IPR3000 run bridged. True hammer of the gods. The monitor tech and the soundman both came over to give the rig a onceover in disbelief. It was a show with banks of 2x15 subs (10 in all) out front, so I could be as loud as I wanted in stage...

I was going to paint Hammer of the Gods on my cabs before I decided on the Boss 302 motif. Definately more fitting with the 15's & more power. Talk about Thunder. Bet your guitarist want no part in a volume war with you.

Regarding those deep "D" cup handles; just how much volume am I losing by using these? I used them without hesitation on a 15/6 tube build, but I plan to use the same handles on a 12/6/1.

Should I be worried about compromising the design when using these handles on the smaller cab?

Sealing is not an issue, (black!) silicone works great. In fact, I used silicone inside the corner chevrons as well. With 1/2" ply, I figure it adds durability - provides a tighter fit and a touch of "give".

Hey guys,

has any one of you ever damaged their midrange driver because of heavy distortion or clipping your amp?

I have a 450W amp (4 ohms) that I sometimes push into clipping. At other times I engage heavy overdrives/distortions into it. How would the 6nD410 handle that? Any likely damage ?

I know I'll be fine with the woofer setup, since I have to run my head at 4 ohms to get enough volume and though am likely to get a 1212/6 which would give me at least 900W of woofer handling power. That's all good. But, is 120W enough handling power for the midrange to reproduce square waves without breaking off?

I know I would be better off with a more powerful head, but I want to upgrade cabs first.

Thanks foryour input guys!

I play loud with various amounts of OD and distortion. There have been times that I was convinced that I blew the mid, but kick off the noise and it was clean again.

Im not a techie so forgive me if this is not accurate, but I believe the crossover prevents the mid from "seeing" lower frequencies that would damage it prematurely. Also, in the spec'd xover, the mid is padded back so it's not getting hit with the same amount of watts as the 15". A full 120 watts to a mid driver this sensitive (and mids are perceptively louder to our ears) would mean you're pushing the 15" very hard as well, so unless you happen to turn it up too far while using some very strange eq'ing, (like, no bass freq's) you might just blow the 15" before you blow the mid.

Edit: I just realized you're doing a 12/12/6, which does ask for more from the 6". I'm sure someone with more knowledge will answer shortly.

That rating is for band-limited full power pink noise for two hours continuous duty -- a very rigorous method.

I've posted Link Removed way too may times, but maybe you haven't heard it. It's a 12/6 being pushed really hard with heavily distorted slide bass. The mid driver just laughs at this sort of treatment, in my experience. :cool:

I don't know about the volume but I just used (1) strap handle on the top. My 12/6 weighs less than 40lbs so it's a one hand carry. This way I don't mess with the internal volume at all.

Thanks for the info, didn't know what the calculation method actually was.

I had heard your clip before, it sounds like the midrange can handle just about anything, but I just want to make sure my setup is safe, since I wouldn't want to damage the cab that could finally suit my tastes and playing needs(and from what I read, it sounds/looks like it will).

Agreed...I'm running my 12/6 alpha wih a 15W practice amp found in many beginner bass kits. I pulled it out of the 6" speaker enclosure it was in, built and stained a box made from the ply I used on the 12/6 and run it...12/6 built per plans.

I can vibrate ALL the walls in my 2400 sqft. 2 story house. Not a great amp and would never do anything with it other than practice and play (as I only do now) but the 12/6 will get stupid loud with any decent amp.

I would love to try a good 300W amp just hear what it can do...The 12/6 can handle a solid 500W.

The 1212/6 configuration will put quite a bit more demand on the mid driver that my 12/6 did, but by all accounts it is up to it. I've gigged one 6ND410 with two 15s a few times (not 3015LFs though, but close) pretty happily. ;)

Ok so everything is done. I fired it up and I get some vibrations from the speaker with a B or E. It comes from the speaker but I guess it is a vibration issue, right? I don't have a bass head right now, I am testing it with a Traynor PA head. Do you think it might be the head giving me some clipping out from the different frequencies or it is likely to be the cab?

I also checked the speaker for grinding noise to make sure it is not damaged and it looks fine.

I did all the seams with PL premium glue (including the handles) and the whole cab is carpeted.
I stapled the damping material inside the cab.
I put an additional brace at the bottom of the cab (it is a 12/6 cube).
I drilled in the crossovers on the shelf.

Any help would be appreciated.

Are there any areas (except for air leaks) that are prone to vibrations?

Wow, I hope you get your vibration/noise issue sorted out because that is one badass looking cab. Love spray painted GB logo!!!! It's got that low-res-low-tech look to it; GB would love it! Did you create a stencil for spray painting or did you free-hand that somehow? Please share.

I made a stencil from the logo. Printed it on a paper sheet, cut it with scissors, took a plastic side from those cheepo duotang , retraced the logo on it with the paper stencil, cut it with scissors and then painted.
