Transmission Line - "C m/s"

[10K2HVN]

Hello,

I found this link in another thread:

http://www.mhsoft.nl/spk_calc.asp#transmissionline

I was wondering what the "C m/s" input in relation to the transmission line enclosure does?

..is "344" really "ideal"..?

Thanks for your help!

Speed of sound defined as 344 m/sec in air is fine. It will change slightly when stuffing is added but probably will not go below 320 m/sec.

Don't use that calculator for TL sizing, it is not correct.

Thank you very much for your input!

Im just trying to fine an easy way out.. Ill actually read through your site one of these days.....

Unfortunately, there is no free lunch with TLs. You really need to do a lot more work desiging a TL then a bass reflex or acoustic suspension enclosure. A horn is even more work then a TL. The quality of the design is directly proportional to the effort expended.

at first i was thinking about copying the SEAS THOR TML for dual SEAS Lotus RW165 midwoofers because the woofers are somewhat similar..but after some searching, i found someone said that the enclosure was not well-designed, so now im thinking of designing my own..but i dont know the first thing about them....

ill figure it out someday.... unless someone has a design that will work well for them......?



Thanks for your replys!
