@audiokinesis Duke, that's exactly what I intend to do - the room is of medium size and self contained, and my hope to gain 6dB with the corner-horn, so your analysis is spot on. And my incredulity is unfounded? That is, it is possible to get good response down into the 20s as long as the driver goes there, even though the Fs is so much higher?
Question: Sub with Fs 54, but response remains above 95dB down to 27: How can I best build
I read a lot of stuff on here from guys a lot more experienced than I, so I'm hoping someone might know some answers. I've got a driver with free air Fs at 54 1w/1m, but free air response remains fairly even down to 27Hz above 95dB, and my question is how effectively can I extend response down to 27? And if so, with what type of cabinet would you recommend? Bass reflex, passive radiators, corner horn,...? What would prevent the cabinet from going down to 27? What would I have to do to make the cabinet reach below 27, to 23-25? Thanks in advance for any knowledge you can share.

@hsbrock , I want to double-check something. It might take me a couple of days. Duke |
@audiokinesis Thank you. I'll be here! |
Thanks @koestner. I am realizing this more importantly than ever. In the past 24 hours I've read in one JBL Speaker Manual sent to me by @ditusa to use 2x4s for bracing (not just little lengths of MDF), and another technically authoritative source said that adequate bracing can make a difference of 3 dB in volume, which to me suggests the wood cabinet can absorb up to 50% of an amp's power in large cabinets, and that's absorbing half as much vibration as the voice coil is producing, which makes sense. I've never appreciated this fact before. |
