Request for 4Pi Plans
type: item
description: Hello, I'm just finishing my modded Dynaco ST-70 kit with the VTA board by Bob Latino and a tubes4hifi SP14 preamp. Now I want to start to build some really, really great speakers. Is it really true, that one can request the building plans? If so, I would like to ask for the plans for the 4PI speakers. Having such formidable speakers would be like Christmas for me. Thank you, Wayne, Sir, for sharing your expertise with us. I greatly appreciate this!! (Sorry for my poor English, for it's not my native language) PS: One question - do they need an impedance linearization?

description: You've got mail! All our models of speakers are very "tube friendly," having high sensitivity and benign impedance curves. They don't need any extra impedance compensation to prevent interaction with tube output transformers.
