Hey, this is for all the people who have purchased a tc9 sub that teamquakecelica is selling on this forum, well I took the plunge and bought one and I need recommendation on the correct size of box to use. Currently I have an 1.5cft tuned to 28hz. This sub would be replacing my IDQ12v2d4. What can I expect different from the tc9 sub versus IDQ using the same box.
