BobbyG2 Posted June 17, 2013 Report Share Posted June 17, 2013 A T-Line for two 18's is going to be massive, what kind of vehicle you have? I couldn't imagine anything smaller than a B-pillar wall in an Explorer would be possible. I designed a 27Hz tuned T-Line for two 15's and it took up almost everything from the C-pillar back. *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...

I was putting it in an isobaric enclosure so to the t-line its 1 18" woofer but power is more cause its two motors for like a single cone and the more the t-line is tuned low the longer it has to be Link to comment Share on other sites More sharing options...
