    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.

    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:

    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 :(

You can sand/cut the brace a bit to provide more travel. I had to do that with mine also, but that was due to a poorly made enclosure that didn't fit together right.
    Ya that is exactly right. The washers hang on the back and they hit the brace. I think IMHO that the AE PR will work better since it wont have anything hanging on the back of it. If the brace wasn't directly behind it, then it wouldn't be an issue.

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

    I designed the Digger8 with 3 goals to achieve simultaneously: dig deep, compact as possible including minimizing floor space area, and low cost. There are plenty of ways to get 2 of the 3 while conceding on one of those so if that's ok for you, the design can certainly be modified to accommodate that. But getting all 3 of those was what t couldn't find in an existing design be it diy or commercial. If cost is not an issue, I would forego the PR and go with a larger driver in a more compact enclosure with a nice amp that has EQ, but that design would cost considerably more, but retains the size and extension attributes. I looked into various PRs including CSS, TC and Seas and had good experience with AE many years ago, but I knew of their typical lead times. The others were just to high in cost for me and the projects goals. But feel free to adjust to suit your needs and budget. I can help if needed.

    Me too. I'm having kanemack help me with the enclosure... It's been so long since I ordered it I too almost forgot about it. Right now I have the JBL 8 in a small sealed enclosure, and it simply is not hitting the bottom octaves I'd prefer it to. No worries though.

    CSS PRs are a bit more expensive, don't look quite as good and probably cost more to ship since they're coming from Canada, right? The TC sounds ones are way more expensive. I wasn't aware of the crazy lead times on the AE PRs but it looks like they're the best bang for the buck by far if you can get em. I think their smaller PRs are less of a priority for them, maybe they'd come quicker if you were ordering 15" or 18" PRs? ;)

    I will let you al' know when i receive the PR's from AE. Perhaps Johnny might be able to run the numbers for the other PR's to see what would work.

    I was happy with the sound and output of the digger 8 until I was watching X-Men First Class and the PR bottomed out and hit the brace. I think when that happened it damaged the PR and is why it has a bend/weakness in the cone. So having a PR that is the the correct mass to begin with should eliminate that bottoming out issue.

    SEAS also has a 10" PR that 300 grams of mass can be added to.

    Anyone considering a slot loaded port? The cabinet could be made a few inches taller so
    as to not loose any box volume. It is even easy to make it flared - I suppose it would have
    to be quite long.

    Or a pair of PE 10" passives to gain some VD but they might require too much weight.

    Scratch that, did some googling -

    Here's the specs of the 12" TC PR (with very detailed physical drawings, could be handy for nikbrewer when designing the cabinet):

    http://tcsounds.com/wp-content/uploa...ner-Manual.pdf

    Again, here's the specs of the 12" CSS PR (again, with very detailed physical drawings):

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

    Though the TC is WAY more expensive.... CSS, is around the same as the AE PR.

    This really doesn't bode well, especially for my first build :(

    I'm afraid I don't know what TC or CSS is :S

    Won't matter. You will be fortunate if it's weeks instead of months. Great product if you have the patience.

    Although I'm not convinced the AE PR's are so much better functionally than CSS PRs that they're worth the excessive wait/frustration.

    I had the distinct impression via the emails that they did things in batches and needed a certain number of orders before they'd start, hence the long lead time.... I wonder if I should just bump my order to 3 PR's as once I've conquered the OS TM/MTM/Digger8 I wanted to perhaps do an integrated Speedster TMM/Digger8 towers or something equally overly ambitious :P
