To build our pa.
The PA is where you want to start. The backline cabs should only be driving the stage, the PA drives the room.

Re: Which cab to build.

They both have valve 4x12 cabs. For pub and club no one needs more than a 112. Unfortunately six stringers tend to all picture themselves as Angus playing at Wembley, and use gear appropriate for that. We can certainly make recommendations for a rig that will send them home crying, but it won't be ...

Re: Good article on SPL

You usually don't get to the melting point of the copper on a coil. The most common source of voice coil failure is burnt insulation, which causes coils to short to each other, which lowers the impedance, which pulls more current, which heats the wire even more, which burns more insulation. Then it...

Re: Should I build TLAH or SLA for TV/Movie/Music?

Build a center and surrounds. There's no reason why you can't wall hand SLA.

Re: Good article on SPL

Not necessarily. Higher power handling requires a larger coil wire gauge, which increases the moving parts mass, which all else being equal reduces sensitivity. You can never look at just one spec, you have to look at all of them.

Re: Stuffing the back of compression drivers

It may make response better, the only way to know is to measure them with and without the foam.

Re: THT Driver

The problem is that it won't fit into the access unless you mount it first and then attach the flanges. With the LP version there's plenty of room.

Re: Omni 15 midrange driver farting

Yep, the bass control should have no effect on the signal to the midrange driver, unless boosting the bass causes clipping. With on board EQ that clipping could occur in the on board pre-amp, in the amp pre-amp, in the amp power amp or in all three. The Alpha 6CBMR did not exist when the original ve...

Re: Simplex Back Panel - Why is it not under top?

In order to build the cab with internal bracing the back must overlap the top, bottom and side edges. There is no strength issue, the wood will fracture before the glued joints will. Someone will probably bring this up eventually, so I'll say it now: 'Traditional' speaker cabinet construction is not...

Re: Otop 8 future build

Make cables with 1/4" plugs on one end and Speakon on the other for when you use an amp with only 1/4" outputs.

I searched online and found a descriptive comment from a person who says they wired there speakers
Don't search on line, read your plans. :horse:
You should not be using 1/4" jacks with PA. Use Speakon only.

Re: Table Tuba 11 inch panels, humming sounds at 20 hz

At or near the bottom end of these horns' performance, the driver in the enclosure itself has some output as a direct radiator, *I believe*. I think I remember this coming from the horse, himself. If this is so, a larger driver would most likely have a bit more output at the bottom end, below the h...
