Well depending on the subwoofer and if I cancel or purchase the new subwoofer I am looking at about 7 months till there may be a new sub in the home theater. There has been alot of changes in the home theater this past 12 months and I can only say I am very happy with the changes that have happened. The current plan if I follow through is to purchase a Emotiva three channel power amplifier which will be the last large purchase of 2019! I might buy another budget 4K tv but that will be for my mother for Christmas. So other than Christmas and 4K UHD Blu-ray movies the amplifier will be the last large purchase of the year. In 2020 how ever that will be where I finish off the addition of Klipsch speakers and I will also decide on a new sub so please let me know your thoughts. Newest purchase is here and now the center is more of a match for the Altec A-7's and the Klipsch RP-600 M's used for surrounds.
