  • Hah hah, I think this "Scandinavian Oil" might have been on the shelf a bit long for it's own good. Had not one but TWO skins I needed to break through. Still, I decided to give it a try and it worked OK, my kind of finish, fairly fuss-free. Note to…

  • Take me to the river!! Nice work. Kudos to the young fellow too. Is that mist (in the second set)? Ghostly. (I'm afraid the image upload code may be compressing a bit of life out of the images... I'll get around to fixing it one day..)

  • Thanks Mal. I found something called "scandinavian oil" on a shelf which looks like just the ticket for a quick finishing job.

  • Getting there... this joins onto thaat... I guess I'll put some finish on it before final assembly... and I just realized that I forgot to drills holes for the binding posts [-X

  • Right! I'd forgotten about that one. Have you tried it? Looks this one might be able to run a frequency sweep and read the accelerometer output - http://www.faberacoustical.com/ios_apps/signalscope_pro/

  • "Optimized for sub" heh heh Well I suppose people need to know that it will work, buying an unknown unit you don't know what the low frequency response will be whereas this one is at least spec'ed at "15 to 20,000 Hz +1/-3 dB". Having said that,…

  • Hi Graham, have you checked the Eco panels for vibration? I can feel the side panels on the mini convertible vibrate with my fingers - or at least, I believe I can :-P I'm wondering about being more scientific. Mostly people just make assertions …

  • Variations on a theme... the idea, basically I suppose, is to make the panel stiffer in both dimensions. Unlike shelf braces, which only work in one dimension. Unless you do a "matrix" and then you need even more good material. Whereas starfish can …

  • MALfunction said: I like Ze starfish Yah, yah!! ) Nigel, the idea is that usually the end of the taper is fairly close to the perpendicular panel. (Or a rigid brace). I couldn't do it in this box because then I wouldn't be able to ge…

  • Thanks Seano! I'm balking at the prices to be honest... I guess I can live with just one for the speaker projects, need to figure out which one. (1/4 inch bolt) [Edit: well I guess it would have to be the one with a 6.3 mm bit - duh] Any thought …

  • Hi Graham... hm, according to Unibox, 112 liters with lots of stuffing will give an f3 of 33 Hz with Q of 0.69, 800W will drive it to Xmax at 32 Hz.
