WHAT Ohms are these speakers? EV 15L OEM type

[davearonow]

I bought these bass guitar cabinets, single 15 encloseres loaded with EV 15" speakers. They are EV model 15L OEM type.

I tested them with a j bass with brand new strings, and used a 400w Line 6 lowdown bass head to power them and the rig sounded amazing.

I thought the head had adequate power for testing but it was really the only thing they had available.

I absolutely love the sound of my bass through my tech 21 DI processor though, and plan to simply add a power amp with these cabs and keep this as my basic simple rig. I need a power amp, and want to use a p.a. Type amp like a crown, or qsc or something but I can't seem to find specs for these speakers even on Ev's site.

Can someone tell me what kind of power I need, how many watts I need to maximize the efficiency and power of these cabs and in particular, what ohms are these speakers? I have always had good luck with crown power and will probably end up sticking with a crown amp. Just need more info so I can match the best amp. Thanks for suggestions.

Prolly 8 ohm each.

Excellent speaker!

That would be my first guess but I kinda want to be sure when I go amp shopping tomorrow.

I bought these Ramsdale cabinets, Rick Ramsdale is a local highly acclaimed audio guy, in particular for his cabs, every one in Central Florida has sung his praises for decades, I got the two loaded cabs at GC used for 89.00 for the pair!



They were in perfect shape and don't look like they have ever even been used. Think I got a pretty good deal.


I'm going to use them, some power, my tech 21, add compression and a tuner and I'm done. Should be plenty of power for just about any venue since we also have a screaming monitor system and I can put as much bass in that as I need also.

Hi.

You can easily check the resistance with a multimeter.

Around 4 Ohm means obviously 4 Ohm nominal impedance, ~8 means 8Ohms etc.

IIRC there was a 4 Ohm version availale, but not as popular as the 8.

For that price, it was a killer deal.

Watch out for the lows though, You can easily blow 'em up even with a 4 stringer.

with your meter, it will read a bit below the rating.

an "8Ω speaker" will read like 5 or 6-something ohms, a "4Ω" will read 3-something ohms.

+1 to being careful, those speakers were only like 200w each,and not really made for pounding bass.

Plus you could call this Ramsdale builder and ask him. I have never seen the 200 watt version (OEM). My guess is they were taken from a salvaged Mesa 2-15.

Thanks everyone. Yes definitely sounds like I need to be careful since I plan on using a five string most of the time. I'm going to call The Speaker Exchange today. They have been in business here for decades and are the go to source for pro audio speaker sales, new, used, and repair. I've had alot of speakers reconed there over the years, and I know they will have all the info I need. I was a little impatient and wanted an answer last night, so, anyway, I will test the ohms, and get their recommendation on matching an amp based on what I want to use them do.. I'll let y'all know what I find out. So I guess the best way to "protect them is to use compression? Or a limiter? I plan on using a compressor anyway, and also I'm a pretty smooth player, don't play terribly hard usually, and even when. I almost never post very loud as we are not an extremely loud band on stage anyway. But I do definitely plan on some sort of protection though. Also, I'm not illiterate, my cell phone makes all kinda of crazy autocorrections to my text that don't make sense, I'm kinda lazy about editing them. Sorry.

When a speaker is labeled 8 ohms, it is actually a nominal reading. An ohm meter measures the resistance to direct current (DC), but music is alternating current (AC). A speaker's impedance to AC depends on frequency and the nominal rated impedance is sort of an average impedance over the usable frequency range of the speaker. You will find that a 8 ohm speaker will be between 5.1 and 8 ohms, 16 ohm speaker will be between 11 and 16 ohms, and a 4 ohm speaker will be between 2.1 and 4 ohms.
