Sure - bring it on brother.

Oh hell yeah! Nik hasn't cut the wood yet so I'd be interested! I have the the AE PR, BASH amp and the REF860W.

Haha, I have sub that's like that with a port sticking out. The port is actually extendable so i can adjust tuning.
Glad to see your guys' builds are coming to fruition.
I've been looking into another design that's smaller, roughly about 0.6-0.7cf with an 8in reaching almost as deep as the Digger8, but requires a Bash amp for the EQ boost. Any interest?

Sure - bring it on brother.

Yep, I got the same message.

"Hello Benji,

Your PR12-970 shipped out today. You will receive the tracking information via email from UPS. Thank you again for your order, have a nice day."


Yaaaaaay! Got everything I need, just waiting on the CNC cut wood which we are finalising the designs on!

Up periscope! Awesome. Nice wine shelf - did you build it by any chance?

Thanks Joe. Yes I did make the wine shelf... and the bar (actually a thorough renovation of its original godawful 1970s blocky satin-black-and-white-Formica form).

Here's a couple of shots of Digger 8 build:




I've only played it with music, and I don't listen to much techno or hip-hop - so I haven't witnessed subterranean synth tones... but I can tell you that it reproduces a Bosendorfer piano and five-string electric bass (both of which have content to 30Hz) with outstanding depth and authority. It's not gonna shake the house like the quad RSS390HOs - with 2.4kW - in my media room, but it makes one helluva 2.1 computer sub!

I almost say... keep the the long PVC port.

Got an email from AE saying my PR is on the build table! Originally ordered on October 24th.

Me too! Yay!

Hello Benji,

Your PR12-970 is now on the build table being assembled. I will contact you after it has been tested, packaged and is ready to ship. Have a nice day.

Built Digger8 and Overnight Sensations for 2.1 PC system. Infinity 860W with Yung 200w (no boost) amp. Ordered AE PR in December; hoping to see it in another couple of months. In the meantime, I fashioned an external port: 3" x 42" This gives Fb = F3 ~24Hz. Hole for port will disappear when the PR opening is cut. Had to put an elbow in it to tuck it in the corner under the wet bar where the computer is sitting. Pretty amazing bass for an 8" sub. I have a few photos of the build I'll try to "dig" up!

I've got two Infinity 8's waiting for boxes. Plan was to use them for two 2.1 systems, but now I'm thinking they might end up as stands for my mains in my HT. Amazing how low these little subs model in such small boxes. Can't wait to hear one (or two )

NP. Hope you guys can finish your builds soon and enjoy the Digger.

Re: Digger8 Sub - diggity dig it all the way to 20Hz

AWESOME jsr! Thank you for doing that for us, gives us another option at least! Can't wait to experience the Digger8!

Re: Digger8 Sub - diggity dig it all the way to 20Hz

jsr, if you could model the CSS PR or let me know how I could do it that would be awesome! Thank you!

I found these specs in case they help:

http://www.creativesound.ca/pdf/APRG.pdf

I figure model the CSS as a possible replacement while we wait for the AE PR's and if they delay as much has been suggested, at least then we have another option even if it does break the budget :(

With the CSS 12", 650g of added mass will get a F3 of 20.7Hz with a HPF at 18Hz. The PR will not exceed its Xmax, but the active driver will at 200W below 20Hz.

I used 575g of added mass with the Dayton 12" PR. The Dayton's cone has a mass of 200g, so a total of 775g moving mass. According to the CSS data sheet, the CSS has a lighter cone at 94g, for a total moving mass of 744g, so about the same as the Dayton. But the CSS has much more excursion, to the point that it will allow the active driver to exceed Xmax. But the JBL and Infinity both have a pretty healthy Xmechanical.

As far as I can remember from this thread/Kevin's thread, the Dayton requires a lot of additional weights to be added to the back whereas the AE PR12-970 already has the right weighting.

I added about 565 grams of washers on mine.

Re: Digger8 Sub - diggity dig it all the way to 20Hz

I am working on one of mine that takitaj sent me as a flat pack. I honestly don't see how the weights in these are going to hit the brace. I guess I will find out when they are finished.
