    Thanks for your input Tom! i'm starting to build up a backlog of projects! I ordered the components for Wolf's Triumph last night and will hopefully start cutting MDF this weekend. i don't expect this project to take too long and will make a decision on the next one soon. Designs by the folks mentioned above are on the short list for sure. Though I haven't seen one by Wolf that used the HiVi tweeter you mention.

    Perfect, thanks! I'll fit what stuffing I can in there without touching amp or driver (or PR's) and will not forget the brace.

    As far as stuffing goes, I didn't have a lot of room to put much in it. You don't want it on the amplifier due to hot parts. The magnet on the SDF is bigger than the Neo in the one I built (no measurable result difference really), so that is taking up more volume. Rumor has it, the plate amps are being sealed better at the jacks than prior, so the whistling from leakage I had (and Tommy on his build) will likely not be an issue. Don't forget the central pole-brace from top to bottom, as it's about the only brace you can get in there. At most for stuffing, you might be able to place a couple layers of batting.

    Just to pile on - I heard Craig's Keramiskas at Iowa DIY and thought they were simply stunning. So good that I used the aluminum version of that SB woofer in what's now my personal best design. It's been a while since I have heard any of Wolf's designs, but the few I did hear sounded great. He had a smallish pair using the rectangular faced HiVi RT-1.3 that sure turned my head.

    You can't go wrong building a project from either of these guys!

    If you don't mind me asking, how much stuffing did you put in the cabinet? And did you line the inside with anything?

    Yes, I've heard great things about your design. I think it might pair well with the first pair of speakers I've built - I think they're called the ELF 1.0. A single driver design from quite a while ago that uses small tang band full range drivers. Sound very nice near field but of course no low frequency at all.

    I found the plate amp and driver (TB W5-1138SMF) at Parts Express, but they don't carry the PR. Found those at another site I frequent where I got the Mandolin kit.

    I love my little Triumph sub! Solid to 40Hz by itself, in room a bit lower.

    Thank you Drjay! It looks like a great build and I really want to try something with a tweeter other than a typical dome. My Mandolin's are fantastic and keep getting better with run-in but I need to stay busy and want to work on a new project. That said, my mind seems to change with the wind sometimes and I'm also considering a woofer module build to augment the Mandolin's.

    l'm also looking at something cheap and fun while I decide on my next bigger spend project and may take a shot at building Mr. Shaffer's Triumph sub.

    Thanks again,

    RDS

    I have not heard most of the candidates you are considering but have heard the Keramiskas and feel they are, by a significant margin, the best small 2 way I have heard.

    That all looks very nice. I'd build what interests you.

    Well, after some additional research I'm leaning toward the Keramiskas. Does anyone have an opinion on how these would compare/contrast to the Bagby Mandolins? I just finished building a pair of these a few weeks ago and really like them. But would also like my next project to provide something different, though stil awesome. Not sure if this statement will make sense, but: Do I need to spend alot more than the Mandolin's to get to the next level?

    Here is a photo of my Mandolin's done in red oak (still breaking them in):
