It's +6dB for every doubling of cab count (assuming they are properly powered like the first). 1 cab=as chart, 2=+6dB, 4=+12dB, 8=+18dB, 16=24dB (etc)chrisj360 wrote:If I was to try to approximate the output of multiple T30's (I have the Lab12 loaded and I think the 3012LF is the closest match), I would just add +3 for each cab added like so?
Is this correct or did I miss something?

Re: Introducing SPL Chart
Could we get the T-45 with 3012l, in 15 and 24" versions, please? (Plus 18 or 20 would be a pleasant bonus, too )

Re: Introducing SPL Chart
I'm trying to see if 4 Tubas @ 50 volts are a suitable replacement/improvement over 2 SRX728's @ ~70-80 volts hence the +12 dB's and +8 dB's added to the charts. Looks like a build thread coming soon.Drey Chennells wrote:nice chart thank you

No, I thought you had modelling software that eliminated the need to build every idea that comes out of your drafting table.Bill Fitzmaurice wrote:Do you propose that I build and measure a cab in every conceivable size loaded with every conceivable driver? That most assuredly is not going to happen.

I lost the up to date source code for the application I wrote to do the sampling. So I'm trying to find the time to update an old copy.
