PMC Twenty.21 Bookshelf Speaker Review

I've said it once and I'll say it again: Transmission lines only make sense in bafflingly enormous boxes. Until you get up to well up over 50L internal volume, they don't make much sense vs a traditional port.

In my opinion PMC use transmission lines as a marketing gimmick and to differentiate themselves. Same with the BBC ties.

I agree. It's a USP.

I will say on the really titanic boxes (MB and BB series) they are genuinely excellent but anything smaller than that is kind of a dumpster fire.
