Default A Big'un - the Audio Nirvana Super 15

I decided it was time to open a thread to capture my experiences with this driver and the box I'm going to make for it.

It's a big driver. Until you have one in your hands, it's hard to imagine.

More about the driver here


Edit: this design eventually became an open back box with a light level of stuffing behind the driver. It's not an open baffle because the highs are mostly radiated from the front whizzer cone and the stuffing absorbs these frequencies behind the driver. The bass however is able to radiate backwards from what is essentially a U-frame so I would expect the rear wave will not by symmetrical to the front wave, i.e. some cardioid response is likely although not measured. It sounds much better than with a closed box.

A big driver deserves a big box. I requested plans for the 13.6 cu.ft. enclosure from the Common Sense Audio.

There will be no supporting woofers or tweeters, nothing other than a wire between the amplifier and the driver.

This is the real deal, a single full-range driver.

Sitting on the floor the driver has been gently breaking in and it sounds very promising.

Default big one

Me too. I note the 1 mm xmax and go directly to my ancestry (AR, TL) and hope for the best on the bottom end...could be great! Chances are the 17mm Matsushita Philcos I enjoy so much in my basement have about that much, or little, xmax. Big boxes. Make them kiosks for art, visual that is. Bigger is better they say. And sit in the middle.
