Design a TRANSMISSION LINE Enclosure with LTspice

Learn transmission line enclosure design with LTSpice and the addon SpicyTL.
Transmission line enclosures (unlike ported enclosures) are easily enough simulated so that the high-frequency output from the "port" can be modeled.
Transmission lines can not only be more EFFICIENT over a wider frequency range than a ported enclosure, but since we can model the high-frequency resonance output, we can also learn to reduce it, allowing us to use a port like design with a driver that would be crossed over higher than where the first port resonances would usually occur!
This is a massive upgrade in audio quality; especially if you were not previously taking these resonances into account with ported design!!!
