Older vs. newer REL subs

@wolf_garcia  Thanks. I'll check my springs (and my neck bolt, while I'm at it).

Others here -- same experience? Subs don't have any issues due to vibration over time? Good to confirm, especially if I'm looking at a used sub.

There's a Q150e like the one I own (and the other one I just bought) on Ebay currently...I can enthusiastically recommend it. (no connection to seller, I simply noticed it)

"...The bad news is that REL won’t service them. If one dies I would try to find somebody to fix it,..."

Good point to bring up for others to see.  This is the problem with buying older -2 prior generation used subs, and when the factory no longer stocks the replacement boards, amps, parts, drivers any more. It becomes a best effort self-fix situation.   Helped many friends rip out stock amps and drivers to replace with generic Dayton 250/500 amps and other drivers to keep them going. Got two DA 500s sitting her right now in fact.    So what's left, a cabinet? Rather build a new Rythmik or Dayton kit sub with a good driver than buy a 5+ year old factory sub that you can't get parts for any more because they've moved on to different designs. Just something else to be aware of when buying used vs. new subs.  And they DO rattle themselves apart after 5 years, and less so when when used more sparingly.  They want you to buy the new model when it happens, fwiw.   

"I'm not in the market to buy two $2500 subs to replace a single older $2k sub; I would entertain two newer $1500 subs, however" .......you can buy the S510 for 2 grand brand new delivered...if you would buy (2)1500.00 subs and not entertain (2)2000 subs which are much much better your wasting everyone's time here with this post as thats just stooopid

@missioncoonery Where is the S510 available for $2k each?

As I price it out, I paid $1k for my present sub, used. I can probably get $600 or so for trade in with the folks nearby who trade and sell gear; if I get two $1500 T/9 subs with them, it totals $2300 rather than $5k. That saves $2700. Not chump change for people who work. If they’re all good subs and my system is not a $30k+ system, that sounds like a fit. More seems like overkill, though I know that’s the name of the game in this hobby for many.

But let’s take your $2k price as something really available (I assume that you’ve got a link for me on that). Let’s also assume that there is no trade in involved. So, essentially what you’re asserting is that someone who would prefer not to spend $1k or a third more is "stoopid" and that this discussion is "wasting everyone’s time here"?

I laid out my parameters and preferences in the OP and my posts, so I’ll leave it to others to decide if I’m wasting their time. Doesn’t seem like it, based on the helpful posts. Of course if you feel your time is being wasted, you’ve got options.
