I'll second that! Why not just stick a bunch of 2x4's joining opposite sides (say 2 per 'level') and alternate directions at each level of bracing? I mean I like cutting holes and all, especially with a circle cutter on the drill press, but those braces are a project unto themselves!
Hmmm... with an 8ft^3 enclosure I am getting a 17.45Hz tune, which may not be all that bad. Remember to keep port at 8" x 49.5". That accounts for the 48" tube with 1.5" for half the flares, provided I can find a 1.5" cutting length roundover bit.
You know... just looking at this thing (the ever changing possibilities)... I may go with a 6ft^3 enclosure and tune this thing to 20Hz. Doing this will assure me that I'll never have to worry about port air velocity and cone excursion even at full power. Look at the differences...
I just spoke with Rodny and he has a roundover bit I can borrow for the flares.
The Reckhorn B1 is reasonably priced, but dialing in a 20Hz filter appears to be a guessing game. I would rather have an indented rotary knob or specific accurate markings. 7 o'clock is 12Hz and 8 o'clock is 25Hz. It would not take much to be off there. I suppose I could always measure the frequency response with sweeps in REW and get it close.
I am hopefully getting the wood cut today. My cabinet builder is supposed to call me back shortly. I plan on visiting Rodny in the morning to pick up the roundover bit for the router. If all goes well, I'll be working on it tomorrow. :T

lol... yeah... he gets paid very well, at least my pocket feels that way. :sarcastic:
I did manage to get all the wood cut by my cabinet maker today... all nicely done!
This will be one I'll have to put together without Rodny's help, but should I ever need it finished for public viewing, I'll have to take it to him.
I'll take my EP2500 and quiet fan with me in the morning and we'll throw one of those extra alarm connectors he has lying around his shop onto the fan for easy swap out.
I have to cutout all the bracing holes and if I can manage to get finished with that I'll start sticking it together. :T
I would like to build the LLT. I will be using the Ultimax 15" DVC. Also have (4) 4" x 18" flared ports to use if necessary. The enclosure will be behind the couch so it will have to be narrow 18"/20" but up to 30/32" tall and 50/60" long. Recommendations for speaker/port location would be...
I should have taken more pictures of this build, but I did most of the assembly in a hurry one night after the rest of the family was in bed. Anyway, I had a full marty with a Dayton classic 15 that sounded amazing but I was suffering from massive room gain in one corner and the inability to...
Hey guys, so budget is a limiting factory for my build its a 500mm cube I don't mind ported or sealed but need sub 30hz(my mains comfortably get to about 35 before they roll off too steep)
I am in the UK so somthing available here would help as I would have to spend on shipping & import duties...
Another build helping my workshop friend with his cabinets.
Mainly music but maybe movies in the future.
Drivers: Eminence Lab 12
100liter probably around 90liters usable.
Ported optional Sealed.
Dual 4" ports.
Tuned to 27hz.
Portspeed below 15m/s
Highpass Bessel 3order 20hz.
1port sealed...
