Hmm, there is nop program to install. So I need advice, I get errmsg when I hit Update, saying macros are unavailable . ??
-
Doh ! I thought the XLS sheet you sent me included the Unibox macros etc. I have just gone to their site and downloaded the program. Everything should work once I get it installed tonight.

Thanks John, Ok I have put the specs in as you recommend and the graph displayed looks similar to the one you produced, but when I alter the mass, the graph remains unchanged. Is there a Run button to recalc everything that I am missing ?
-
John, I am tying to use Unibox and am having trouble entering some of the PR specs. eg ones in Red appear to be Read-Only eg Vasp, Cmp, Rmp. The values in the spreadsheet do not match the data sheet from Scanspeak. What gives ?

Nice. I can only imagine how far a 6" driver must travel when trying to deliver sub 40Hz at a reasonable SPL. Any chance the PRs are bigger? say 8". If so maybe an 8" driver might help. I got a 6" pianist for Xmas one year......

I think I'll take my bike for a ride down to Newport with some washers and a bottle of wine under my arm. Prefer to spend on some wine rather than spend on 1-time only scales. Got a system worth sampling, yet ?
-
Are there any drug dealers here ?? I need to be able to weigh things in grams, possible 200 of them, but nevertheless I need access to scales in that range, not to mention enhance some late night listening sessions. Perhaps there is another method t…

Thanks John, I am surprised that the Weight is not displayed in the legend, it is an important factor. That dark blue line looks pretty good. Can you run it again with 50 or 100gms more ? I am wondering about moving the knee from 29 in your graph…

Coincidence, my subs will be 370mm external cubes using 25mm MDF, no bracing. Using 10" driver and PRs. Target is around 30L but accuracy is less important when I can just add/subtract a washer or 2 off the PRs. John can explain what you will need…
-
Graham, it is a great idea. Don't know how many subs you have but some say multiple is better than one. As for calculating the volume of the box, without being too anal, you should unbolt the driver or a PR and have a look inside. Have a look at …
-
I has thunk about this a bit more and decided that my idea was crap and John's suggestment is much better. So I will install 2 opposed PRs to reduce the box dancing around the room and this will also address the concern of using PR with a same size …

just googled "passive radiators larger" and got hits. "Now, we need to select an appropriately-sized passive radiator. ALWAYS use a passive radiator that is larger in diameter than the active driver, as the displacement of the passive radiator usu…
-
Hippy ! It is written 3 posts earlier - do I have to go searching ?? can't you google up PRs and have a read ? Something about the limits of their excursion being easily achieved, so suggestion is to increase the area to avoid Xmax. Perhaps "conven…

thinking of adding pieces of gold to "tune" the PR, since it won't tarnish.

Peerless. Got a part number and some T/S parms 'n all.....

What is bandcamp ?
-
Been a long time, but the memory lives on..... a very unpleasant shake. I got 2 off a crappy old guitar amp...never wanted to go near it after that, even though neither was the amp's fault. I reckon sparkies can probably remember each one clearly. …

Cheaper to go to a Sydney Target and buy some clothes which stay in Bathurst until the next year. Would help the Jones's with their Friday night game of Whose Undies Are These... "ooh, that's a strong odour..... smells a bit... yes, definitely…
-
Graham, if you want to extend your Bathurst trip to include Syd, I have a spare bed (and 3 more if I send my son to stay at his mum's). Plenty of rheum and as you know plenty of ways to get into trouble in Syd.....

Joz flew up to Syd and hired a car one year Syd-Bathurst-Syd then return trip. Quicker.....Joz is made of money though....
