Building my first cab

Sort by date Sort by votes

If this happens keep in mind that big of a cabinet will need a fair amount of internal bracing...ok a lot of internal bracing.
The mentioned internal sub chambers for each driver or at least a pair of drivers is a good idea and will work as some of the bracing at the same time.
Yes it will be big and heavy!

Maybe try a smaller cabinet for your fist cabinet building project

Yes, a 4-15 cab would be big and impressive looking, and it would be impressive lugging that into the venue, but I'd rather impress with my playing. Now there's a novel idea! 😉

IF it will fit, and if there are stairs...

Careful you don't blow it up using those 800-watt Class D amps. They'll put out all 800-watts into 2.67Ω and those old Kustom cabs weren't designed to handle anywhere near that amount of power. Typical power back then was 200-watts in a high-powered amp back in the 60's and 70's.

IMO, this is very overstated. I think there's a lot of misconception and misplaced concern about over powering speakers.

Why stop at 4-15's? Why not build an Ampeg SVT style 8X15 cab?

I used to design and build bass cabs. I also once (one too many) owned a Peavey 412 bass cab. Stupid heavy, large and couldn't come close to my fEARful 15/6 cab in volume, power handling, tone and portability.

What is it you hope to achieve by building a 415 cab? Because you can?

My fEARful 15/6 cab (next to my 110/6 cabs)...

Tell that to my recone tech, here's a picture of one from last week that was clearly WAY overpowered to the point that it pushed the VC out of the gap and tore the cone neck from the spider:

It's interesting, I have an old Peavey 412 TVX bass cab and an LDS nEarful 15/6 that I got to AB a full volume one day. Even though the LDS gets significantly less power since its 8ohm and also has lower sensitivity, with a Shuttle 9.2 it was almost as loud and much deeper than the Peavey.

If you didn't grow up going to deafening, yet unintelligible concerts that left your ears ringing for weeks, are you even a real man?

I'm thinking also there's a lot more to this story than just a simple overpowering. What was the speaker brand and model. What cab was it used in. What application was it being used in and what was it being powered with. And who was the operator. The closest failure I've seen to this in my 25 years was only once with someone using a 750 watt DB750 into my HT322 cab. That cab could easily handle that amount of power, but not the idiot plugged into it!;-{

There's always an element of poor judgement, not enough rig for the gig, an accident, or idiot involved in such damage, but I see enough from the main stream player world that it's an easily justifiable caution IME.

In the case of the DB-750 into that cabinet, clearly it couldn't handle that amount of power based purely in the results. Many players aren't perfect, I know that and accommodate them too.
