No, I've never been so bloody stupid as to try it.

Why would I damage my difficult and expensive to repair equipment proving a point to ill-informed gimps on the internet?

I can fairly well guarantee that you've never actually metered the Voltage*Current function of them though so your assertation that you've delivered the power is totally baseless.

Once again, go discover what crest-factor means. If you want to dick-swing about doorstops, I ran mine from an SR-707 for a long time until moving to light-weight amplifiers. Doesn't change the laws of physics.

The argument was done after my first post. Everything you've said since demonstrates you haven't a clue Clap

Go cry to the admins about the swearing, pigshite being spread about by idiots is called pigshite. If they don't like it they can update the filter. Meanwhile I'll continue having fun playing with my EVMs that I apparently don't own or use LOL

That’s like saying “up to 1million” and then backtracking to “I meant 200… that’s in there on the way up!” 🙄

Asserting you have fed them that and they survived unharmed is also misinformed pigshite.

I refer to my previous comments, an amplifier rated at 600Wrms doesn’t mean you’re feeding your speakers anywhere near 600Wrms. Go and learn what crest-factor means as you obviously don’t understand the relationship between signal content and speaker power.

You can’t feed them 60-120Hz on a 500w/8R amplifier with something the crest-factor of live music without them getting beaten up, let alone a setup capable of feeding them anything close to 600Wrms.

You’re either deeply misinformed or knowingly bullshitting, are you sure you shouldn’t be posting in the scoop section?

I see I've touched a nerve because all now you haven't said if you tried it or not. Yet, you are cursing left right and center LOL  

All you are saying it can't be done. Meanwhile, I've used 8 EVM 15B Series II loudspeakers on 2 QSC EX 4000 Amplifiers from 60 Hz on up from 1990's - 2000 and, never lost a driver. I retired the drivers once I upgraded to the QSC PL 6.0 and upgraded the top boxes.

Argument is done. Go play Chess. Obviously, your knowledge is solely based upon reading specification sheets and, have no real world experience in regards to the EVM 15 L and EVM 15 B.

Best Regards,

That said who knows what the op has.


sadly i own the old non proline models with 200 watt rms.
when i buy the amp , i want to buy one that can drive 8x the pro version with 400 watts each comfy.
i dont plan on killing my speakers , but if one dies , the recone kits are only aviable in the pro version so i want to plan for that.
using them as subs , i will be limited by xmax anyway , or else i will just kill them fast imo. i wanna be gentle to them.

Interesting thing about these, i think the 2.5 inch coil must be in a very tight gap,which obviously helps the sensitivity, but every one i have owned, the cone excusion allways feels 'rough', as if the coil is rubbing, yet they all play well when in a cabinet.   Thumbs Up

hey jbl_man , all my drivers are the old non proline 200 watt rms version ( at least i think) i want to
wire them up in 4 ohm pairs , my amping is still a big ? , i will get to that when i finished the caps. 
for testing i can use 2x yamaha p1600.
for all other people , i know the material i own is not nearly anywhere "pro".
i just wanna have fun & a fairly good sounding rig for private parties. no need for huge bass orgies / 8x 2000 watt subs. 
just in it for the fun

They are absolutely not Sub or Heavy Bass capable, do not even try it. You'll also have to be absolutely religious about the high-pass filter.

The best boxes for them IMO is the TL606AR (or ARX) as built by Shuttlesound (previously the UK EV distributor). I have the plans for these if you are interested and IMO it is a considerably nicer take on the design than the original TL606 designs from the EV handbook.

Shame you're not in the UK as you could buy mine LOL

iam really interested in those boxes , you mind sharing the plans with me ? maybe i will use subs / infras under them one day , but for now i think 40hz lowcut , moderate power and my plan on how i want to use them and for what , i think i dont really need or have the money for subs. 

thanks for the help !

The higher tuning offered more punchy bass from 60-70 and up, but needed dedicated subs for an overall balanced sound.


thanks for the help !

thanks for the tip

600 watts is way too much , even i know that. 
since they are non proline , they are rates for 200.
600-800 would straight up wreck them in seconds & then i gotta recone 8 drivers Wink

I am interested in this thread because I have 14 working ones (Bbfl) in eliminators. DH3 comps x 8 working fine. I just think they could be in a better box. 
I don't want to abuse them but what would you do with them? They cost 54,000 yen 350 quid, here if you buy new. So not a cheap driver. That doesn't guarantee sound quality I no. 
Where to put them? In the bin? rite now used they sell for peanuts.
Road runner sir I am not really into driving things to within an inch of there life. I would rather keep my speakers within there limits. It works out cheaper in the end. That day I was just amazed they didn't break that's all. Made me think that they are better that I thought.

200Wrms (Thermal) on the early ones later increased to 400Wrms (Thermal) due to a combination of different testing standards and better thermal properties of the glues, lacquers, etc.

Not that it actually matters if you’re using them for bass duty since they’ll mechanically exceed their capacity before they do thermally if fed real-world content instead of test tones

The 12” & 10” versions had a bit more of a non-sensical rating scheme that seems to have varied depending on who they were OEMd to, etc.

The DL series appear to have opened the gap up slightly and lined it with Teflon, it really is like threading a needle on the EVMs which makes cleaning the gap out on a recone *so* much fun 😂

Interestingly the EVM-18B can also be rarely found with familiar Blue labels and an LS-1801e designation…
