Arash Posted November 20, 2012 Share Posted November 20, 2012 I have a CW with Bob's CW1526 woofs. they are so bass shy. the bass is tight but not lower than 50hz I think. I've heard them with tube and SS amps, no luck at all. I want opinions about "what's wrong?" [] possible issues: woofers are not broken up (they got ~100 hours of play time) it's about dampening materials it's about XOver ... .. .

moray james Posted November 20, 2012 Share Posted November 20, 2012 first off check to see if you have both woofers wired the same with respect to polarity. Second Bob is your friend so why not ask him first. Good luck and best regards Moray James. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted November 20, 2012 Share Posted November 20, 2012 MJ has a pretty good answer. The woofers being out of phase is the only thing I could imagine. To troubleshoot that, just exchange the position of the positive and negative leads on one woofer and compare the difference. If the bass increases, you've identified the problem. If the perceived bass decreases, then that means the woofers were already in phase. You could run them w/o the crossovers to rule out crossovers as a problem. The crossovers are also a place where the polarity might have been changed by accident. Quote Link to comment Share on other sites More sharing options...

If the perceived bass decreases, then that means the woofers were already in phase. That would work BUT if you choose the wrong one, the woofers will be in phase with each other but you'll have both woofers out of phase with the mids and tweeters. Best to trace the wiring.

Daddy Dee Posted November 22, 2012 Share Posted November 22, 2012 oops! [:$] My bad! Thank you getting this right. Indeed, best to trace the wiring! Quote Link to comment Share on other sites More sharing options...
moray james Posted November 22, 2012 Share Posted November 22, 2012 Check the soeaker wire first then reverse one speaker wire lead to one of the cabinets that will tell you if ther is a wiring issue inside one of the cabinets go from there. I need another beer. Best regards Moray James. Quote Link to comment Share on other sites More sharing options...
lucky5115 Posted December 3, 2012 Share Posted December 3, 2012 For whatever it's worth. I did some testing over the weekend and had similar results on a pair of speakers. Turned out to be my receiver(built in amp). Ron Quote Link to comment Share on other sites More sharing options...
coolhandjjl Posted December 4, 2012 Share Posted December 4, 2012 I'm surprised no one mentioned cab placement. Boundary cancellation issues perhaps? Quote Link to comment Share on other sites More sharing options...
DizRotus Posted December 22, 2012 Share Posted December 22, 2012 Are these the speakers you built? If so, what is the crossover? Is the port (size & depth) correct? Quote Link to comment Share on other sites More sharing options...
Arash Posted December 29, 2012 Author Share Posted December 29, 2012 Are these the speakers you built? If so, what is the crossover? Is the port (size & depth) correct? the cabs are a 1989 CW cab which motor board is changed to CS motor board. nothing else (ports dimension) is changed. everything is what should be Quote Link to comment Share on other sites More sharing options...
Arash Posted January 7, 2013 Author Share Posted January 7, 2013 I'm sure it's all about damping materials. what to use? come on guys gimme a remedy I'm dying of this problem and I'm some kinda starting to change my mind to replace the Klipsch with a new kitsch product out there do woofers need a break in period?! they got less than 200 horus Quote Link to comment Share on other sites More sharing options...
sootshe Posted January 7, 2013 Share Posted January 7, 2013 I've tried lots of different dampening materials in bass cabinets, but I always come back to the old fashioned fibreglass insulation. Seems to impart a warmer smoother sound to the bottom end. You may have to line over the top of the fibreglass with some speaker grill cloth to prevent the fibreglass from flying all over the interior of the cabinet with the air pressure from the bass driver.

Rusty Melton Posted January 8, 2013 Share Posted January 8, 2013 My Cornwall I's seemed pretty bass shy as well, I used them with a set of KG 5.5's to help with the bass output. I changed out the old crossovers with a set of ALK Cornscalla wall crossovers and now the bass is much improved. I guess the 42 year old crossovers must have been shot because they sound great all by themselves now. Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted January 23, 2013 Share Posted January 23, 2013 Try pushing them back against the wall as close as you can get them. That is, however, how they got their name. They can be used in a CORNer or against a WALL. Quote Link to comment Share on other sites More sharing options...
