New 5'' midrange driver from eminence!

[rogypop]

Its neo, it reaches up to 10k, its not expensive. Great news for anyone who likes tinkering and designing the cabs. (I already see it mated to eminence delta 12lfa in inexpensive 12/5 project ) Eyeballing the spl chart it seems it could be quite cool sounding, in ballpark with faital m5n8-80,
but cheaper.

Just low sensitivity... Some of the other mid drivers are a little louder.

 

[INTP]

That's a pretty significant peak above 5k

Perfect match for kappalite 3010lf

That peak is there probably to compensate for beaming north of 4k.

Just noticed they now offer all kappalite LF models in 4 ohm version too.

Too bad they don't show off-axis response.

Hey look at that they sure do. But with the sensitivity losses, you gain nothing by going with a 4 Ohm woofer over the 8 Ohm drivers.

 

[rogypop]

From the engineering standpoint i agree with you, but from sales department point of view i strongly disagree.

A little louder?. At 93.5dB SPL and 80 watts it's only really suitable for a home HiFi cab, once you factor in some crossover insertion losses you will be struggling to be heard in the midrange in a cafe without live drums.:-(

This is respectable 102dB SPL. so will only need a third of the power to reach the same apparent audio level.

Yup! low ohms = more power with lower speaker count, that will suit a hell of a lot of complete idiots that will go on to do this to far more of them:

and Eminence will sell loads more replacements, good plan.:-(

i like how they say the usable range goes to 20k, then the chart shows a cliff at 10k. : )

That could happen to just about any driver if you use a lot of power but fall short on using your own ears and common sense I meant that the average customer Joe is more attracted to the
4 ohm offerings because he thinks ''he can use the full potential of his amplifier'' that way.

Check out the eminence alpha 6a, which is successfully used in fearful 12/6 design, it has got a few louder peaks but the same broadband sensitivity as this new model.

Common Sense? You haven't met many bass players have you.
They are the idiots that dont understand the many advantages of multiple loudspeaker coupling for sensitivity and impedance reduction, freeing real useable audio level increase.
They are the ones that are trying to run a bridged Crest 2.0 into a single farting Neo 112 and think if they only had a 4ohm driver they could hear themselves because they would have twice the power.

 

[rogypop]

shhhh Bassmec, this is the hornet's nest I'm a bass player myself and i think more cabs equals more of the good thing. I prefer high sensitivity cabs and moderate powered amps running cold, basically idling while pushing some serious air.

It will work just fine paired with a Kappalite-class 15" woofer.

I have a cab that pairs a 95.5 dB, 450-watt woofer with a 91 dB, 20-watt cone midrange. So the woofer is 4.5 dB louder and has 22 times the power handling. Guess how many of those wimpy little mids have blown in the field? Zero. Why? Two reasons: First, I cross them over properly; and second, the spectrum of bass guitar doesn't put a ton of power into them in the region where they are running wide open.

So how can a midrange "keep up" with a woofer that's about 5 dB more efficient? Two things: First, its radiation pattern is much wider, so it's putting just about as much sound out into the room in the crossover region as the woofer is, despite its on-axis response being a lot lower. And second, you may not want the mid being as loud as the woofer anyway, at least not across its entire spectrum.

This is respectable 102dB SPL. so will only need a third of the power to reach the same apparent audio level.

The problem I have with the mid you linked to is, its amazing loudness comes primarily from a 9 dB peak at about 4 kHz (this isn't apparent in the factory curves but I and others have measured it - it's that big dustcap breaking up). In my opinion, that's just about the worst place to have a peak. That's where the ear's sensitivity is the highest, so that mid "cuts through the mix" very well, which is what some people prefer. My personal preference is for a mid that "sits in the mix" very well, which would call for a very different voicing. You see, "cutting through the mix" sounds great in theory, but if it means having a 9 dB peak in a region that belongs to electric guitar, it can instigate a volume war (in which everyone loses).

That Eminence mid will sit in the mix beautifully. It will definitely show up in cabs that I build.

Actually I'd say that the 4ohm model has practical application in a 2x subwoofer cabinet with a total impedance of 8ohms. So that you could pack more speakers onto a single channel of a pa amp. Of course, with them as a pa subwoofer, you shouldn't need too many to get a good volume. I'm not saying that you're wrong, just that it does have a practical application.

 

[Bassmec]

Well Duke I have no spare power as hostillaties have long since been declared in the metal volume war against booming downtune guitars.
I have a graphic in my Ampeg pre that can losslesly pull that frequency back if it's too glassy but I won't be
wasting any precious ding dang diddly ding out of my KT88's that way will I.
Flat response Studio monitors? we already got some.
I have gone away from my three way active solid state bass rig I used in the late eighties and back to loads of bright efficient full range drivers and 200watt tube amps.
The twangs the thang.

 

[Bassmec]

Alternative ways to skin a cat.
My customer list is interested in the sort of bass tone goals he gets with the pedal switched on.

But would vastly prefer that in studio with less hiss and noise from the pedal, so we want it baked in the loudspeaker rig available from the limited pre amp EQ of an old school tube amp.
Horses for courses!
We don't all play blues, reggae and soul.
So I don't want any loud sub bass, the live PA reinforces that if necersarry via the DI.

That's a pretty significant peak above 5k

It's actually a bit less than the peak of the Faital M5N8-80, which I use and have measured. That being said, the peak of both of these mids is imo in a good place: It's north of the region dominated by electric guitar, so it lends itself to "sitting in the mix well" instead of fighting with the guitars on their home turf.

Alternative ways to skin a cat...

Indeed electric bass is a cat which can in more ways than one be skinned!

Notice the thermal power rating on the new 4-ohm LFs: 550 watts. This is because they use a thicker wire to get the DC resistance down, and that thicker wire can handle the heat better.

In addition to this new little midrange and 550-watt 4-ohm versions of their Kappalite-LF woofers, there's another development at Eminence that is imo worth mentioning: Engineer Jerry McNutt is now their Product Design Manager. Jerry designed the Kappalites and many if not most of the other woofers we swoon over on this forum. This is a good time for boo-teek bass cab builders and for hard-core do-it-yourselfers.
