Default Cost-No-Object Front Stage

Someone emailed me, and asked what I would do in a "cost no object" front stage.

Basically, if I was prepared to take a car and chop holes in the dash, what would I do?

This kind of system isn't in my wheelhouse whatsoever; I'm kinda obsessive about NOT building systems that reduce the value of the car. That used to be my thing; in the 90s I took the wheels of my car and cut a hole in the wheelwell to mount my midbasses.

I don't do that anymore because it makes the car un-sell-able.

But...

If you're into that kind of thing...

I think that I would replicate a prosound monitor and jam it into the firewall.



For instance, these are the speakers that I use in my den. They're Yamaha DXR 12s. These things are capable of something like 135dB. When I listen to them, I generally have them set at about 2-5% of their maximum volume. These things are beasts.

The setup is fairly straightforward; there's a Celestion compression driver loaded into a waveguide that's about 12" wide. The woofer is twelve inches in diameter.

It's going to be tricky to fit a twelve inch woofer up front, but there's lots of eight inch woofers that get hella loud. A B&C 8NDL51 can produce more than 120dB from a single unit.

I'm a big fan of unity horns, and unity horns would work nicely here, but there's only one unity horn for sale (mine) and mine won't do 120dB. That was intentional; I didn't want to create a horn that would take sales away from Danley Sound Labs. So my unity horn is nice, but it's nowhere near as loud as the Yamaha DXR12.

I think that Mic Wallace has a really nicely engineered car, and I'd make mine like his if I were willing to cut into the firewall. I wouldn't use Image Dynamics horns, I would use something like 18Sound. That's not a knock on ID horns, I simply prefer symmetrical waveguides.



Here's an 18Sound XT1464, as an example of a nice waveguide. I've been using 18Sound XT1086 as my "goto" waveguide for speaker measurement for ages.

In principle it would be quite simple to waste the surplus labour of the world by building temples and pyramids, by digging holes and filling them up again, or even by producing vast quantities of goods and then setting fire to them. (Orwell)
