nugget Posted December 30, 2012 Share Posted December 30, 2012 Hi Just had my schroeder cab apart to repair the crossover, all done and putting it back together I sealed the rear panel as the sealing strip ripped a bit when opening. I noticed that both jack sockets are open and not sealed I normally use one of them I've been reding up a lot lately on cab building as I fancy a pair of BFM jack 12's and the common problem a lot come accross when building cabs is sealing them, a lot of people seem to find little leaks from the sealed cab. So are the open jack sockets on the schroeder a problem? Thanks Dave Quote Link to comment Share on other sites More sharing options...
nugget Posted December 31, 2012 Author Share Posted December 31, 2012 I just tried shoving a speaker cable in the spare socket (making sure it wasnt touching anything!!) and ran it in the house, it did make a difference - took away a minor farting sound that I didnt know was there until it went away and tightened up the low end a bit. Definitley gonna whip the back off tomorrow and remove the jacks and seal the holes with some sort of blanking plate Still interested to see if anyone else has come accross this??

nugget Posted January 1, 2013 Author Share Posted January 1, 2013 Played last night in a fairly big club and the cab sounded so much better (tighter?) than before with the dummy jack filling the spare open hole. It MIGHT have just been superb acoustics in that room as we havent played there before. Is there any way to correctly check how air tight a cab is?

Protium Posted January 1, 2013 Share Posted January 1, 2013 My 1210 originally had a Speakon and a jack so I just replaced the jack with a second Speakon Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted January 1, 2013 Share Posted January 1, 2013 (edited) Hi, all cabs leak a bit and so do the speakers themselves, through the gap the coil runs in and sometimes the surround. This is accounted for in the design process as a 'fiddle factor' for leakage called QL. I doubt that such a small hole will affect the sound much except as you say by cutting down extraneous noise which we would only hear if we were listening for it. why not just buy a couple of jacks to plug in the holes or a couple of 1/4in dowels from a woodworking shop, you could screw a washer to the end so you have something to stop them falling through and give you something to tug on if you need to remove them.
