I definitely want to build a pair of 1 pi's for my office so if you could send me the plans for those I would really appreciate it.

Thanks for the warning on the large cabinet size for the Thermionic 4 pi. Within a few months I'll have the music system in a really large room so the 4 pi might work. But for ultimate flexibilty of placement I may have to do the 3 pi. - I appreciate your wisdom on building a mock-up speaker first. But I must be missing something- how doI find out about the cabinet dimensions without the plans? Are the dimensions on your website somewhere and I have just overlooked them??

Also, is there a difference between the thermionic 3 and 4 with regards to midrange naturalness? I wouldn't mind a little deeper bass but with owning 2A3 amps my main concern is how natual vocals are reproduced.

Thanks for all your advice,
