I did an interesting experiment. Two monitors were placed on the ground and the microphones were placed in the middle. The frequency response and level of the two speakers were all adjusted to the same level. At this time, if the same signal is pushed at the same time, logically speaking, The sound heard at the position of the microphone should be in the middle of the two speakers, but in fact it is not, even completely to one side

Sorry for the distraction but I really should do my Youtube videos this way. Set up several wedges in a big warehouse and lecture to them. Sounds freaking great! Did I mention that I am not an engineer, but I do know a German engineer and a Czech one too … I said … a Czech one too ….

Mr rat. You are the craziest of all, but i do love the orginally and the environment where you test the gear. I have used L'acoustics in many different ocations and i believe is the best off them all. Thanks for the video

I think there's some kind of dependency between max stable SPL and form factor of wedges with complicated reflection/resonance system of microphone plus face. I mean – the narrower (close to the size of the head) the wedge, then more higher stable SPL can be reached.

Gain before feedback is largely a function of the consistency of a speaker’s dispersion and frequency response. It is the absence of lobes in the dispersion pattern that permits higher perceived volume before the onset of feedback. Smooth dispersion across the frequency spectrum is very hard to achieve, requiring serious research investment. Most pro companies show their speakers plots at a variety of frequencies. The ones with the smoothest response plots at a wide range of frequencies are going to be less susceptible to feedback, all other things being equal. It should be said that the same exact thing applies to the microphone. The polar plots give a lot of useful guidance.

I've had the pleasure of using "Pro Wedges" before and I can say that they are the best sounding monitors I've ever heard! Hearing your vocals in all ranges singing low like Elvis or high like Plant. With these you will be able to sing at your best!

You dont even need to worry about any of that if you use Bob Heil microphones. testes..testes… one two testes.

Interesting video. I might be taking a too much of a technical approach, but isn't this just testing the frequency response of the wedges? You can actually see the dips on the spectrum analyzer. You could think of it as a factory eq'ed wedge. I can honesty say I don't know if i'd like that, the technical voice inside my head says I'd want to control the frequency of that dip myself. But then again it is probably pretty practical in the real world. I'll probably never know, the band I mix uses in-ear, makes it so much cleaner though.

Just landed here and checked out this video. When pushed hard I thought the MicroWedge 15 out performed the rest with the MicroWedge 12 coming in second. Nice design. Nice work.

HEY DAVE , It has been 7 years since you did this Video , It is about time you do a new one . This time do one on as many different monitors you can get your hands on to test . Also Leave out the Gated Reverb this time . Love learning from you . The Best places I have found to learn from are BAR BANDS . They are on the road 300 days a year working with equipment that is as old as dirt and HAVE to get by with what they own . But they make it work and Grow up to be like you … A Hard working Man .. Good Luck in all you do ..

Dave, thanks for sharing your knowledge. It seems to me like the Microwedge are slightly pre-eq'd from hearing the noise test? Still very interesting test. The toughest mons I've had to work with are the QSC KW122. The horn is not suitable for monitor duty IMHO…

Peter Swindley 26/09/2021 - 2:31 Sáng

Difficult to say whether this is really a fair test. it seemed to me that whilst the D&B probably was slightly less stable, the microphone was being aimed more directly at the wedge than with the other models. Plus we don't really get a sense of how clear each design is. For me, a good monitor provides the most clarity before feedback, which might be different to the gain before feedback. I still like the MWs however.

Ah, just seen you take apart the monitors, split drivers as opposed to coaxial.

What are the likely reasons for the 3 dB difference between the D&B wedge and the microwedges?

I should do though to be honest so far I kind of do these videos last minute and fairly spontaneously when I have time and an idea. I do intend on putting together a better/cleaner setup to make the videos.

Can I ask why you do not wear a wireless mic tied directly to the camera instead of using a camera mounted mic so your narration is properly recorded?

Well, first lets clarify. 1"(throat diameter) typically refers to drivers with 1.75" to 2" diameter diaphragms and 2" (throat) usually refers 3" or 4" diameter diaphragm drivers. Lets do the math on surface area (Pi*Rsquared and circumferences (Pi*D). 2" dia would be approx 3sq inches & 6 inches. A 3" would be approx 7sq inches and 9 inches& a 4" dia would be approx 12 sq inches and 12 inches. More surface area increases max output, more voice coil circumference increases power handling
