Default Suggestions for winter DIY project...

Hi everyone,

I'm gonna be building a single or dual DIY sub this winter (Probably SEALED, but not ruled out a Ported version).....I want to compensate a little bit on the upper range (40-80hz) for music/etc with some tighter and faster response Bass.

I've narrowed down the Drivers to one of these (although suggestions are most welcome):

Styke AE12:

Adire Tumult 12":

I'm planning on making either a single of dual design, and will try to make a rosewood finish to match the Ultra.....couple of preliminary designs I had in mind to copy of some you folks :

The AV12 and AV15 are good woofers. AE Speakers is the name of the company, and AV is the name of the driver series. Right now, there are no AE Speakers HE woofers because an improved design is in the works. Stryke Audio was reorganized into two brands, Acoustic Elegance and AE Speakers, so that means that you couldn't order a "Stryke" HE12 even if you tried. Such a driver has never even been commercially available, but I think that John (proprietor of AE Speakers) has considered it for the new model line. The new AE Speakers HE series woofers are expected to have a woven carbon fiber cone with an aluminum thread woven in with the carbon fiber and the same clear-anodized inverted aluminum dust cap. No word yet on how long this will take.

I recommend a SonoSub with an AV15 driver. That's this one: Click the image to open in full size.
They can safely be used in a down-firing configuration. That's critical for building a SonoSub. The output from one of these bad boys in a big (8.8 cu.ft.) sonotube would lay waste to an SVS 16-46 PC-Plus. All you'd need to really pull one of these off would be a table saw and a router. You can use plexiglass to make a circle cutting jig for a router, which would give you very smooth round shapes for the sonotube endcaps.

Looks like you want to go 12" with this...

Any reason why not a 15" box size asside?

In case you didnt know in general a 15" driver will:
Have much greated displacement with equal excursion
Have higher sensitivity with equal BL
Have less distortion at low bass(due to smaller excursion requirements mostly)
Require a larger box(the downside)

Thank you BAM, for that info....much appreciated.

ok, so here are some follow-up questions:

1. Which would provide a better acoustic signature or sound, in a sealed box: An AV12 or an Adire Tumult 12" ? I will probably not go with a 15", and definitely not a Sonosub because of aestitic reasons! My wife has command over that, and she absolutely would pull her hair off if she sees a sonosub

2. I don't have a PC-plus, but rather a boxed PB12-ULTRA, which provides me with Plenty of SPL and extremely good sub 30hz (and subsonic, <20Hz) bass.......what I'm looking for is more of a Tight bass strictly for music to complement the SVS Ultra. What would be the best configuration to try? SEALED or VENTED?

I also want to match the finish of the SVS's Rosewood veneer, so I'm gonna try to stay away from too many fancy designs....

You want to use something in-between of your main speakers and your subwoofer? You could go with a high sensivity pro driver too. The AV12 or AV15 will be nice, but you could ask John to make you some Lambda woofers with Faraday rings, you won't have them for christmas on the other hand.

BTW, with the AV15, you could discard that SVS, that's why your setup is a bit special hehe!

Yeah, Lambda drivers are a custom build that takes extra time you might not have for this project.

Default Snow Horn

Didn't Adrian Mack build a great big horn speaker in his back yard behind his deck out of lots of snow and a garden hose to ice it all up hard? Cool project put one next to the hot tub turn up the volume and you have a jacuzzi. Tried to find the picture no luck. Anybody got a copy of that picture? Hey! probably very little thermal compression with a horn like that! Regards moray James.
