Does anyone know how long subwoofers are designed to last, provided you don't abuse them (i.e. bottom out driver, play at absurd listening levels, etc)?

Does anyone have experience with REL, Velodyne, or Sunfire Subwoofers in this regard? I recently purchased a brand new Velodyne D10, and just wanted to see how long I can expect to have it last.

Years. Unless like some people on this forum, you try to kill it.

No idea. But FWIW, I've used a Paradigm sub for the last 10 years and it still works just fine.

I've got a pair of old Velodyne CT-150's that are about 8yrs old (I think). Both are still fine.

I have a 20 year old Velodyne ULD-15 sub-woofer. I had the feedback cable come loose (it has an external amplifier) while it was playing (about 4 years after I bought it), which caused some damage. Velodyne fixed it (and upgraded it at the same time) for free. It's been working ever since and still is doing a great job.

NOTE: The ULD-15 replacement (equivalent) is the newer DD-15.

I got 10 years out of a Velodyne HGS, I'm actually sending it in for repair as it has a bad amp but the driver is OK. I replaced it about 6 months ago with a REL but will continue to use the Velodyne for the LFE channel.

If it's a budget JBL sub, don't hold your breath!

Around 20 years give or take a few yesrs,depending on use and even as important what conditions it has to endure.

If the sub is placed in a room where temps are maintained around 18-20 Celcius with normal humidity...over 20 years should be the norm.Of course ...humane livfe...not blasting Transformers III and Mickey Mouse VS Batman IV at near Xmech. To satisfy curious AVSer's who want to see if the " Stoopid" Loud Barrier can be pushed and impress the kiddies.


On the side.

Drivers with compressed foam sourrounds should be treated(the sourround part IMO),drivers with rubber sourround have in general a linger life span as the sourround cannot dry rott like foam.It will dry,but it takes much longer.

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

Actual designed to last?

Average MTF on most electronics these days is 5 years by design. The engineers have sort of settled in on this one as the cost -vs- real life span number.

That means some fail from on first use and some last 10, 15, or even 20 years.

PS: I am hard a can be on my subs. I've blown more than a few over the past decade and a half.

Foam surrounds these days are now specially treated to resist dry rot. They will last much longer.
