Got a 2245H 18" woofer off of eBay. And a surround kit for the future. Guy threw in the cab for shipping expense. 3/4" MDF.
Internal dimensions are 27.5" x 19.5" x 42.5". Port is 8" x 8" x 20.75". Port exits one end of the box and the driver is below it.
I am using a Carver TFM-22 strapped mono for 350w into 8 Ohms.
I have a JBL/Urei 5235 Freguency Dividing Network.
Given the dimensions, port and driver what should I be using for a crossover point? The 5235 is currenly set for 800Hz. That is too high. I plan to change the channel 2 board in the 5235 so I can take the LF from channel 1 and feed it to channel 2. Channel 2 would be set to give LF at the needed point. That will got to my pre-amp (for volume control) and then to the Carver.
Does JBL still offer the 8630 boards populated or blank?
