EV EVM 15l possible for SUB use and how?

One has been re-coned with a non ribbed cone. They measure very similar in the horns.
Rob.

You have created a 15b.
Doesnt seem like it matters in horns though.

Hi Leon,

Oh, btw, the 15l is out of a Zeck 3-way stage monitor.

Zeck, of course, how could I forget 🙂

So you say that even if I build bjornos enclosure it will drop like a rock below 70 hz?

In the low end the EVM15L-II worked better in ported models than in real life and I wouldn’t be surprised to see similar behaviour in other types of enclosures.

With a relative high BL, low Mass, low Qts and a very high EBP, it has a steep roll-off. You can mimic a higher Qts by adding a power resistor in series with the woofer. It will lower the sensitivity while frequency increases, resulting in a more gentle roll-off (more 'flat' response).

My Dad has a pair of them and one of the 15l blew.
So he exchanged both of the woofers to get deeper bass out of them.

Perhaps your father already knows the answers of your first post 🙂

Cheers,
Djim

You can also set your house on fire if you aren't careful by doing this.

I was trying to say this but no matter how I worded it i sounded like a dbag.

Rob, thanks for posting. I simmed both the L and B and they appear identical too. That said, I am willing to bet Art's comments are related to performance at war volumes and under driver Fs. I am quite happy with my 15B's in my horns (70hz) but they are parked in the house. Almost all well known 15s easily sim 6db+ over the 15B in my studies. That said, very few drivers have extended HF response like the 15B does if you have a 2way setup. They are great at what they do but they are not a sub driver.

I asked because you guys might have some enclosures that worked around that, like a ripole or something.
But if it isnt woth it i will just sell it. Need to find a buyer though.
Thanks for all the answers guys!
Just say it if you want the 15l.....
And live close maybe, because I dont expect international shipping to be cheap.

Much smaller than the first one (about half sized), easy load on the cone (800cm throat), may be driven to full output with a 50W amplifier (100W/4Ω plate amplifier).

The cones crumple in PA when driven with 200W+ amplifiers, should be fine with only 50W or so (and over 125dB!).
