The CT 219 is a transmission line subwoofer containing a Peerless SLS-8 driver. The Udo Wohlgemuth design has a triple folded transmission line where the driver was placed at 1/3 of the duct (CT 221: 1/3 and 1/5).

CT 219 (the smallest), CT 220 and the powerful CT 221 are forming a range of transmission line subwoofers with different outputs.

Considering their size all subwoofers show an astonishingly low frequency response.

Klang+Ton review of CT 219, CT 220 and CT 221:
..."The CT 219, with a cut-off frequency of around 80 Hz, in conjunction with five CT 214 is ideal for smaller rooms or for those who prefer lower volumes. Somewhat to big already was the CT 220, a subwoofer that likes to be partnered with CT 215. This set is more than adequate to let loose a few dinosaurs knocking down some less robust trees even in a somewhat bigger room. Realistic sound levels, however, were only achievable with the CT 221, since five satellites with 17'' drivers each, running in parallel at 4 Ohm require a powerful companion. As a result, even music videos turned out to be enjoyable, for what's a rock concert at a moderate volume supposed to be!"...
