out4u Posted April 30, 2020 Report Posted April 30, 2020 Had the subs for a few years but only just recently got to using them . Did I bottom out or what? I have seen quite a few blown subs but never this. It's sounded off since I put them in, and the truck hasnt been drivable till now so I just recently got to take it for a ride , coil is not burnt and ohms out fine. Obvious scuff marks where it rubbed( which when I shut it down to further investigate I found it frozen)
slowfkncar Posted April 30, 2020 Report Posted April 30, 2020 The glue that is supposed to hold the pole is no longer holding it together.
out4u Posted April 30, 2020 Author Report Posted April 30, 2020 Well that really sucks 😕 wasnt even running them hard gains all set properly with dd1 0db on headunit -3 db on amps. Given I have them on 2500 watts and it's a 1500 watt rms sub but I figured that would be fine especially using -3db tones. This isn't my first rodeo but godamn I figured it would take more than that to kill it or a coil would smoke before something like this.. I can't even get the thing back centered it won't budge.. Its a 18" crescendo forte wonder if I can get a compatible recone somewhere like psi so it's not just a paperweight before I get rid of the rest and go back to sundown since they have never let me down...
CstrokerV Posted April 30, 2020 Report Posted April 30, 2020 Could of been dropped and broke my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/
out4u Posted April 30, 2020 Author Report Posted April 30, 2020 Maybe during shipping =/ I've had them in the box for 2-3 years until I got ready to use them , didn't see any signs or dents on the boxes though. Sure wish I could fix it somehow. I kinda feel like it was a bad glue job if it did loosen up, I don't know why the pole would be part of the magnet or bolted or something seems like poor design to use glue for that but I don't make speakers for a living so idk maybe there's a reason. Out of all the subs I've owned over the years this is a first. I still have 4 sundown e 12 v1 I use for basement parties and I used to beat the hell out of them on double the rating and they are still going strong. 2 sundown x 15s I also beat on and a friend still has them going strong. I'm just gonna get 4 nsv4 18s that was the plan anyway just made me need them sooner
SkarredSierra Posted April 30, 2020 Report Posted April 30, 2020 Crescendos qc isnt good. They send out a decent amount of broken shit. Also their cs is garbage too. Cant go wrong with sundown. Or skar or american bass.
out4u Posted April 30, 2020 Author Report Posted April 30, 2020 I can believe it..there customer support is pretty bad to hell I've waited 7 months on an order they told me 2 weeks for, to bad my whole build is already them oh well still getting back on the sundown train.
out4u Posted April 30, 2020 Author Report Posted April 30, 2020 Top plate shift I think I can fix it either way I feel like this was def a defect.. so done with crescendo. Never again
SnowDrifter Posted April 30, 2020 Report Posted April 30, 2020 If not from a handling error, baffle flex could do it too ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
out4u Posted May 1, 2020 Author Report Posted May 1, 2020 I could see that however it was in a wall with 4 layers of 3/4 mdf and tons of bracing internally and all seams glassed. the only flex i have/ had was typical stuff like windshield, doors, dash.
