I do not have any feedback on Y connectors but I do have some on Adire Audio product I saw in your home page. As a current owner of Adire’s Shiva, I can tell you that going with their subwoofer driver would be a wise choice. In fact you will be impressed with the performance of Shiva alone. Tumult is a few steps above Shiva and despite its hefty price tag, the spec of this monster is mind boggling. If you do end up getting it, please post a review on it. I’d love to hear what the experience is like.
