is ED still good? check this out

well. i've owned...when my last one gets here will be my eighth ed sub.

all have been 9kv.2s, or their 8" sub.

the first time i powered up my first set, they rattled like a mofo. when i took them back out of the box to ship them to ed for inspection, the dustcap popped off of one. it was repaired and i was told they couldn't get the other to rattle.

got them back and they were still rattling. sent back again. the one with the bad dust cap was replaced, the other sent back, again, without them finding a rattle. they told me it had to be the box i built. an air leak or something

hmm... got tired of the shitty rattle, went to buy two kicker cvr 8" subs. they still sound fine in the same box.

i tried to sell the 9kv.2s on icixsound. no bites for a long time. so whatever, someone wanted to trade me two more 9ks for a little amp i had in the basement. fine. great. they also sound fine in the same box. odd.

well, i decide since i have four of these things, i'll build a box for four. i do, to their specs. same rattle. i've pinpointed the one. same one that has had a rattle since i got it. also, found the other sub i've had for a while had two spots on the surround coming unglued. also, one of the two subs i got in trade had one spot on the surround coming unglued.

so, i send all 4 back. they are all still under warranty. figured i'd get black dustcaps on them. for 10 bucks a piece, why not?

the two new got black dust caps and were reglued around the surround. one of the older two was replaced with new 9kv.3.

now, the last one, the one that has rattled from the beginning, cannot be replaced under warranty. i have to pay for a replacement. suddenly, the adhesive that holds the voice coil to the former melted. that's the rattle. apparently i pushed them too hard. after all this time, they find the problem, and it's my fault.

so now i'm getting my fourth one back tomorrow. i got a replacement at a discount, but i'm still severely pissed.

i guess i don't need to post my opinion. you probably get it

im pretty willing to bet that the rattle is either a misaligned coil, or a loose spider landing (most likely the latter). is it volume dependant? does it get louder with the volume?

 
sort of gets louder with volume. it only made the rattle on certain notes.

regardless, they said i pushed it way too hard and melted the adhesive that held the voice coil to the former and it stuck in the gap.

i had to pay for a new one

 
they fed you a line of bs my good sir...

if it melted the glue, that should have been a manufacturers defect. there is no way that the metal on the coil could have gotten hot enough to heat up the glue an inch or so up the former... the coil would fail first...

their was either not enough glue (most likely the case, see my previous posts about their gluing inabilities //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ), or the glue was defective (they could have forgotten to put accelerator on it //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif)

 
oh, i'm sure it was a line of bs. but, directly quoted from their rma ticket system- "The former and voicecoil were stuck in the gap. there is no reason that would be caused by a defect."

what can you do, you know?

About the only thing you can do is what you are doing ---- let others know how bad that company sucks.

 
WOW!! I would encourage anyone who is considering an Ed product to watch that video!



If you still opt to buy one of their products, it is your own dam fault.
Terms like, "incredibly purpose built" just make me want to pounce on the driver.

He then goes on to brag that there are no "over the shelf parts" on their products. Followed immediately by him admitting that other vendors use that same basket and that they didn't need to tool their own because this one does everything they need.

Yeah, okay Ben. Shave that cheesy *** catcher off.

He also mentions how their cones are built specially to avoid glue failures... yeah, he knows a thing or two about glue related failures.

 
it actually changed my perspective on them //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

seeing as how they make the last true SQ woofer on the market //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

maybe he was able to go back to school and get an engineering degree with all the money he stole. you know, to come up with all those nifty (not new technology by any means...) ideas they used //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

 
Glue got too hot eh? I have a prototype here with a 2" coil and 1.2" winding height... Kapton former, etc, etc. I put 400 watts RMS on it for 60 minutes on a Bass Mekanik intermittent sine wave (40 Hz). It was hot enough that you couldn't even touch the RIM of the basket outside of the box, much less the motor structure... but no glue failures.

Sounds like either BS or crappy glue to me!

 
yeah. funny thing is, before i sent them in, i was throwing 1600 or more watts at them. not on voice coil failed, but the glue holding that one melted. and, the 9kv.2 is rated to take 200-400 wrms. but I was puching them too hard
