Default Ported box for TAD Tl 1603 ? Calculation help

I have calculated the Tad 1603 in different programs and get different answers each time .

Can someone help me ?

Iīm going to use it up to 50Hz. My room is 80m2 I want it to be as small as possible. Iīm not sure if iīll use 1 or 2 in each speaker. I want it down under 20Hz.

hi, if small size is your prerequisite, why not go for sealed with linkwitz transform and a cheap-to-recone 18" beyma LX60 ?
"a sealed equalised subwoofer will simply wipe the floor with anything else, provided that you have done your homework. "

TAD looks like cool choice for 2way instead , no ? I wouldnt sacrifice it for sub...

oh and the plots JBL made for the SFG follow up 2226 showed TAD 1601 with worst power compression , so its not really cool for sealed use. Anyway the topic is about ported, whats interesting is that Kinoshita "20hz" studiomonitors not use 16" TAD but 12" -s ...

80 m^2?! My room is only ~35-36 m^2 and there's plenty of room for a pair of 566+ L cabs, so I'm curious why size is an issue.

Regardless, different programs round off the calculations more than others and/or use different assumptions, but the cab will be large to go low at low distortion, so using the largest design is a good idea if you don't measure the driver's specs.

If two/channel is used, then double the single driver cab size/vent(s) and of course to get below 20 Hz in a vented cab will require tuning to the desired frequency with 0.707*Fs being the practical limit in a typical BR, MLTL, 4th order BP.

GM: I just donīt want it to look like a PA speaker. Iīll build a nice curved box together with the 10" and horn on top.

I'm sorry, I thought I had. I mean I explained about your design software confusion and gave you some additional guidelines for using them, so what specific help do you still need?

Mats, i wonder if you ever built cabinets for the 1603's? I have a pair and 11" TAD midranges also and am looking to build cabintets this month. I would love to see what you did.

ark: Yes i buildt 2 single ported cabinets for them but i donīt remember the size on them. I made a pair speakers to my mom with a single TAD 1603 in bottom and a Jbl 2446h 2" driver with a tractrix horn above. A passive Jbl 3110A 800hz x-over. The x-over isn`t ideal but it works for untill i have time to fix a better. I have to take down the 2" a couple of db.

I can measure them and take a photo of them this week.

For my own project i changed the TADīs to 4 Jbl W1500H in sealed 80 liter cabinets each.
Project TAD - MeanAudio.
The CAD drawing isn`t final yet.
