Collection: Shop All Diaphragms

Please note that all crossovers are built by-hand, to-order. None of these crossovers are "on the shelf and ready to ship". Throughout 2026 I have stayed consistently behind a backlog of more than 100 pair of crossovers. Please understand that this is a one-person business so there are delays in my ability to answer the phone and respond to emails as I rarely get to sit as my desk these days due to the number of crossovers that I need to build and test while also shipping out all of the other items that sell every day. Thanks for your patience as I work to catch up on all of these orders.
