I'm going to build a TL sub
Hi all,
I'm going to build a TL sub, based on MJK MathCAD TL sections model. After played around with the program, I got what I think the best, but I'm not sure, so I post it here waiting your comment. I got box outer size (LxHxW)=83cmx45cmx34cm, I will use 2cm thick MDF panel. If there is any better solution from what I got, please let me know. Thankyou in advance for your help. Chris. MCD file can be downloaded from HERE (don't forget to change the extension from ggg to mcd) Below is cross section drawing of the box: |

Hi Volenti,
here is my driver specs and box data, I will use it for HT mostly, my room size is 13ft wide and 20ft long. Is it to much stuffing for the box? (system SPL only reach 87dB average) And please look at Terminus Opening (So 9,1=0.05.Sd), I make it a lot smaller then original design (0.77.Sd), it made system time response look smoother (the last graph), but I didn't see drastic change in another graphs, is it good or bad for the system overall? thanks. |

I don't have whatever worksheet(s) you used, only the original TL WSs he released, so can't reproduce it to view........ GM
