Hello, I agree that having a true subwoofer efficient below 40Hz is needed for todays EDM and such. EDM has signals as low as 20Hz, with harmonics even lower. I was planning on using the TH18 40-150Hz, and building Ricci's Ghorn for 20-40Hz. (to replace reflex) I have found that it is better to keep the <40Hz to its own dedicated sub, as the volume the driver cone needs to displace is double going from 40-30Hz, and double again for 20Hz. So doppler distortion is inevitable if trying to cover that entire range with one sub. I have a 4 way DBX4820 crossed over at 40, 150, 800Hz. Kind Regards,

Hello, That is great results indeed. Nice work. So you recommend going with the three board CC as measured with your current design? Is that with the B&C-115? Kind Regards,

Hello, I am also building some TH18 XOC1 cabinets. I will be trying the 18IPAL and comparing to the standard 115. Do you have details of the throat V boards you have made from your throat picture? Thanks in advance,
