Hi there g: in Post #3, you introduced the possibility of using a musical instrument driver speaker). Recommend you pull up the information from dealers such as (P.E., Madisound, US Speakers) and look or the manufacturers published FR curves. MI drivers all have big peaky response at higher mid HZ. HI FI divers have more smooth response. ...regards, Michael
not "all" MI drivers have peaky responses in the upper midrange that's an unfair classification that smells of hi fi snobbery we need to stop factionalizing audio.
nothing wrong with looking elsewhere when you run out of options in the classic categories.

Hi there T: This post edits my last post. ...regards, Michael
I've been well pleased with tang band's w4-1320sif in Bjorne's TABAQ cabinet. Very accurate reproduction across the vocal range with nice clarity and depth. I've supplemented them with a pair of Dayton classic 8 inch subs, each in a 135" mass loaded transmission line that reaches down to 20 Hz though, in retrospect, a single pipe of a slightly larger cross section would've been sufficient. The TABAQs may also benefit from a tweeter crossed around 4kHz but I would not say they are lacking in highs.

Look at the response curve. You could run it to 5 kHz without a crossover and it would be better than a lot of "midwoofers" with a second order crossover. Off axis response is excellent to 3 kHz. Impedance @ 3 kHz is about 12 ohms, easy to work with.
I haven't used this driver yet, but it's on my short list. Budget builders might think it's expensive for a midrange, but the flexibility the driver offers in regards to woofer and tweeter selection, and also in crossover design, should more than pay a budget builder back.
All this depends on whether the datasheet is to be believed. I've had good luck designing speakers off the graphs and T/S parameters. It gets you real close.
Some guitar speakers are peaky, especially when driven with old school tube amps. This is a characteristic cherished by many guitarists.
Stage monitor speakers are designed to provide accurate sound for a vocalist. Often the drivers are intended to be used full range and can cover a fairly wide range of 150Hz to 8 kHz or so. Crossed over I think many could make very competent hi fi midrange.
I'm intrigued by these drivers. Dayton Audio PA130-8 5" Full Range PA Driver They have response to 10 kHz; maybe a little peaky, but no huge peaks. In practice this might make a nice line array speaker (available in 16 ohm too) and you can't beat the price. It might make a very good hi fi midrange too.
Yes i agree. However an important data is missing. The THD of the driver.
I understand this kind of measurement is very rare in the spec sheets, unfortunately.
Morevoer i am more and more interested in higher efficiency drivers.
Imho a driver that can output let's say 100dB/2 meters in the assigned range without sweating it will even more relaxed at lower levels.
Strange peaks on the response can be an issue with this kind of drivers.
Hi and yes i have seen for instance the Celestion drivers response. But I am not ruling out an extreme measure 😱 the use of digital eq. I know it will complicated the audio chain a lot and some people are completely against this. But the advantage is to have high efficiency and i guess low distortion.
I could be able to use low wattage amps as well at least for the mid-high section.

as a monitor tech my observation over the years is that 90% of existing designs are all two way with either 15's or 12's for lows and horns for highs which tends to put crossover points smack dab in the midrange which is something i don't like and unless i'm mistaken was ginetto's prime objection, crossing over in the "critical" mid band.
did anyone look at the Radian stuff i referenced?
FastEddie could you show me a monitor design that covers the mid band from 150hx to 8khz on a single driver, i'd love to see one, it would need to be a three way and with two x-over points had better be ultra flat and narrow directivity to qualify.
the EVM 12L was manufactured as a guitar speaker but saw more use in monitors and the mid section of many PA systems, i guess those old school guys weren't influenced by prevailing biases or preconceptions.
i deserve some flak for taking exception to the comments made earlier, fighting against preconceptions comes at a price.

Hi ! do you have a link to a datasheet maybe ? i have said i am very confused on the subject. If this one sounds very good indeed i stop immediately to worry about placing the cut in the mid-range. Immediately.
I am only looking for great sound especially with voices/choirs and similar music. I like to understand every single word in a speech just to explain my ultimate goal. More an engineer approach than a music lover approach 😱
Hi ! exactly it was my doubt. It still is.
A way to test could be if possible to rethink the x-over a little.
Usually these pro bass drivers are almost wideband.
So that a 3 even 4kHz cut could work fine, depending on the driver of course .
I am for paper cones and high efficiency ones in general. They have a sound that is very lively and fast.
i like this attitude 🙂
maybe. But some of the most fascinating discoveries were made by fighting preconceptions ... 🙂 Preconceptions are the quite the opposite of science.
thanks again.
I would counter-argue that it's actually worse to cross over "smack dab" in the middle of the frequency range where the ear is most sensitive, i.e. 2-5kHz:
Marco
Thanks a lot. I will read it during the week end.
Again something that sounds very good MUST be good 😉
no prejudice here against pro drivers at all. For one thing they should be very robust indeed. If they bear a continuous pro use in a domestic situation they should last forever. Very good.
P.S. maybe i have to take a look at the wideband drivers section ? a 3ways could be a woofer + WB + tweeter in the end.

I have heard many great sounding 4 and 5 way speakers, with crossovers inevitably in the sensitive area.
I have heard horribly sounding 2 way speakers trying to avoid sensitive area.
Its all about execution.

to marco gea in post #33 you should have continued to highlight further to include "which is something i don't like"
so please re-read the statement and take the time to process it fully.

Btw that 5FE120 mid is good suggestion, i have recently built nice open baffle bookshelf with it and with B&G Neo3 as tweeter with open back, meant to be used with sub. After some initial troubles with two breakup peaks on mid, i redesigned and simplified crossover, and now i am quite happy with it, sounds balanced, musical and involving. One feature i always pay attention is phase behavior around crossover frequencies.
About four different bookshelfs i built recently, the ones with minimum phase change sounded best, assuming flat fr response on axis and good behavior off axis.

i fully agree it's about execution if driver response and x-over don't provide a proper summation the flaws are easier to notice.
and from a monitor tech perspective if the x-over region has any bumps and wiggles it can cause spurious feedback when a performer moves the mic with respect to monitor.
flat response controlled directivity are key to getting good levels without feedback.
i guess that may not be applicable in a reproduction circles because there are no open microphones.
