Blew my 12".....AGAIN!!!!!

[rufus.K]

Someone has suggested to Eminance 3012, but Spec sheet shows useable frequencies end at 57Hz. Still do not know what to do.....DRAT!!!

There's a 3012ho, and a 3012lf.
Which did you look up. The 3012lf is a champ.

May I suggest that you just don't have enough rig for the gig?

The math is pretty simple actually... Knowing the SPL sensitivity at 1 watt/1meter at the lowest frequency you intend to reproduce, then extrapolate to the safe power handling of the speaker (using the RMS or continuous rating, not the program or peak rating) if the resulting number is less than your needed SPL at whatever distance you need it at then you do not have enough rig to accomplish what you hope.

These are exactly the calculations used when determining how much PA is needed in a touring rig to get the job done acceptably.

I suspect that you are WAY off in the ability of any 112 to meet your needs.

I don't have any numbers either but my guess is four of those 112 might put out a minimally acceptable compliment of sub bass thump to go with 8x8.

I got a DOD Meatbox pedal which has a TRS output which splits the signal, one dry to my pedals and amp, one effected which I run to a Behringer subwoofer. The Meatbox delivers the proper frequencies to the sub to really give you some serious thump.

No way??!?? Really?

Please...

I'm not going to post a resume here, but I have worked with some of the finest loudspeakers in the world - Bowers and Wilkins - and I know what I'm talking about.

But you just keep believing that you can use any driver you like.

That's hifi stuff. Different world, really.

A driver is a driver. Applications don't matter, because they are all reproducing sound. What feeds the speaker is irrelevant, it's how the speaker behaves.

 

[Downunderwonder]

You think? I figure that since below 100 Hz it's not doing much, bring it up and it will, in a more useful range, with less power (he'll need to turn it down). No? Betcha.

it's a biamp. The 8's are all over 100 to 200 already. Your scheme takes from the 8's and piles it onto the already overtaxed 12. What's the solution? Raise the crossover some more? No.

 

[tfer]

Enough polluting the OP's thread.

Good luck buddy - but the people outside of this separate discussion are giving you good advice. You are simply overpowering your 12.

I hear ya but my thought was that he'll end up turning the 12 down, probably a lot. Because it's suddenly making lots of sound where before it wasn't. I don't know, just a thought.

he's got 5 making NO sound already because he couldn't hear them dying trying to keep up with the mini fridge. Enough of this madness!

Not at all. I've stated multiple times that if the excursions are equal, the larger driver will ALWAYS be louder with better bass response.

By the same token, what you gain in bass response, you lose in transient response because smaller speakers have a higher transient attack.

There's a reason that subwoofers are large, and tweeters are small.

And from sales response, combinations of 10" drivers seem to be where most bassists are happiest. If you need more bass, at louder volumes, you simply add another pair of 10s.

I saw a pic on here and he had it all figured out. A 410 with a 210 ontop and another 210 on that. SO he has the ability to: 210, 410, 610 and 810 for whatever size gig and look good while doing it. Plus 210 X2 or 410x2 in stereo.

All magnetic speakers work in the same way. How you move the voice coil is irrelevant: it could be from an iPod, a CD, a guitar...hell you could use a 9V battery to move the coil. It doesn't matter. All that matters is how the speaker reacts to that magnetic charge.

Fundamentally, sure. Real world application? I don't think so.

I actually have a 210, a 2.5 (2X10 with a 5" HF driver) and a 1X15. I always use the 1X15. I add the upper cab depending on the gig. The 2.5 is vented, so it adds a little more bottom end.

If you believe that fundamentals and real life are different, then we will never agree.

Yup, that's what I'm trying to tell buddy with the blown 12. The TL EVM15B has always been the go to cab for quality, volume and portability. One easily keeps up right beside the drums.

I want us to! You said a driver is a driver. They're not! There's a huge difference between a hifi speaker and one meant for pounding bass, or guitar, or PA use. And there is possibly no more demanding source that a high powered bass amp fed by an aggressive played bass guitar. Way different than a music source. These are really very different technologies and applications, with very different goals.

 

[B-string]

Fundamentally a speaker is a servo motor that is attached to a diaphragm.

By the way the EVM 15L and 15B's had a pretty poor Xmax and Xlim (excursion).

But the science is identical. The manufacturing and materials are different.

 

[David Jayne]

Yes but the DESIGNS are also different, way different.
Like I said, I'm no expert. But I pay attention and I've been here for ten years and I've learned that when guys like B string and Agedhorse say stuff, you probably should take notes.
