Hey all. I thought i would ask the DIY community for a little help. Since ED is now dead, many customers will be hooped if their drivers fail. Unfortunately, the various model driver specs are not available on the website anymore. If any members have the specs or know of a suitable replacement for any of their drivers, please post.

Great minds think alike? wink.gif Good idea.

Here is what Chris Schempp posted in the other thread. I also recall eD had posted internal volumes and tuning frequencies in the spec section of many of the products. I might take some archive digging as most of the models aren't listed in the store anymore.

Thanks for the help and thread bump Mark. Looks like i was writing here while you were posting in the other thread. Id like to agree with your great minds comment but sadly when it comes to this stuff yours is the only great mind in this equation:rolleyes: hopefully the community can come up with some replacements. I know i will probably like to try a different driver someday if i can still use the same box i had made.

From a depth perspective, the Mach 5 UXL-18 would be a good replacement for the 19OV.2. However, you would have to increase the diameter of the hole some.

What about a TC sounds LMSR-12 for the 13av2? The cabinets are stellar and would love to drop in two of these guys to compare.

sorry to hear about your driver problems, but who cares about dead driver specs?

what you need to know are the enclosure and amplifier specs, then a good set of drivers can be matched even if they have different specs than the ed specs (which seemed to have some questions surrounding them in the past anyways).

Listen. It's All Good.

Any one that has a two year old or newer a2 300. That above info is wrong. I took mine out to see what it looked like and was less then impressed with the driver . Alex would never tell me the truth. But when I wanted to talk to matt about making a clone since they are out of biz he honestly replied that it is theayton classic driver that cost $85 at parts express. Wow. No wonder mine bottoms out all the time. They go from the original 16 mm xmax to 9.5. Kinda dis honest on there part. But if you have a newer a2300 you probably have his wimpy pe driver.

How have you isolated your 110v power supply to the amp to eliminate ground loop hum?

Yes, powering up the sub on an isolation transformer and without any other connections hooked up, it still hums.

Now it's taking up space in a spare bedroom...
