I am considering Oris 150 (Lowther DX3) with Pi 7 or 10 bass bin (possibly with JBL 2226 or Eminence Magnum 15HO). Could I get copies of plans for Pi 7 & 10 bass bin?

As mentioned above, I already have a pair of Lowther DX3, and am wondering if there is any alternative to Oris 150 (among your offered products) that will take advantage of DX3 that would go well with Pi 7 or 10 bass bin?

Also, another question is on the price listed for speaker kit. Is that the price per pair?

Thanks so much!
