EAW use quite a lot of these drivers and I believe they cross them typically around 450Hz to 500Hz.Something out of the ordinary has happened to lose a midrange with these settings.
They are rated to cross at 300hz, and I use them to that point regularly.
Here are some more details:-I would be interested in more information about this box as it becomes available. Thank you..
Have you done any comparisons with a EAW KF394?
It uses a similar Mid/HF driver, if not the same driver, as your design.
I've done a few gigs with that, it's a very good speaker.
I have noticed the same thing.Looks like you have made a pretty serious speaker. Do you take orders
One really fun thing with speakers that sounds this good is trying to guess how loud it is before you look at your SPL meter. The lack of distortion in the speaker itself removes some of your reference points, so you're constantly 6-10 dB low in your guessing until you get used to it. Going back to another speaker, you start mixing at a lower volume because it sounds "too loud".
The first time I ran into that was when I took the SH-50s I owned along with some Labsubs to a gig. It didn't feel loud at all until I tried to talk to someone and had to scream to be heard. IME: .
I have noticed the same thing.
What I have also noticed is that for some reason there seems to be a lot less "ear fatigue". Your ears don't seem to ring as much-even though in many cases it is actually louder SPL wise.
But even though it is so loud you can't talk-some people say "It's not loud enough" because they are looking for the distortion and they associate the distortion with SPL.
I have run across BEs who mix for a particular level of distortion-not just SPL. Give them a little it of distortion and they will back the level down.
We don't use "normal" crossovers in our products.
Out of curiosity – approximately where to you cross the HFdriver(s) in the SH96HO and J1?
I would expect you to be doing all of that - my curiosity was about the compression driver you are using in these particular boxes. Its capable in a large horn of operating down to about 300Hz; I was just wondering how far down you were taking it and how much work it was doing.We don't use "normal" crossovers in our products.
Yes we use high and low pass filters-but they are at different freq (often overlapping), sometimes with different types of slopes and often some out of band eq.
This is done to get the best phase and amplitude response.
Of course the acoustical and electrical crossovers are different.
But as a "general" idea it is around 1500ish Hz(give or take), I don't recall off hand.
Often times we use multiple "crossovers" in a product. In one case there are actually 4 "crossovers" for the HF.
As with many things-there is no simple singular answer.
That’s the opposite of reports I have heard; people have describe the sound as having a lot of impact, like being hit in the chest with a hammer, however they have all been in relatively small boxes - around 190L per driver.Having heard the 21SW152 in a fairly large reflex box, i wasn't impressed at all with the performance. Yes it shifted lots of air but the sound was kinda undefined and it lacked definition. Perhaps if combined with an upper bass cabinet the result would be better. Crossed at 80Hz to a 15+2 top box it definitely lacked punch.
This makes sense from my experience. That, and my theory that most don't get the opportunity to LEARN how to manage actual sub bass frequencies. I did a walk in last night and of my many suggestions was setting up a proper aux fed sub system with appropriate eq and dynamic abilities to manage the subs separate from the top of the system. I had years of club experience and being able to adjust the 'feel' of the system by slight 'tilting' if the sub/mid hi balance, especially effective when the crowd density changes.My experience with the 21sw152's has been the opposite of Marjan's. I've used them for around 4 or 5 years in a variety of cabinets. Often when people talk of one box being subjectively "tighter" or having more "punch" it relates to the lack of deep bass in the output of the system with a "tighter" sound or the presence of elevated levels of 2HD and 3HD. Subwoofers with lower extension sound slower because the low bass IS slower. As with most things it is best to listen or research and form your own opinions. Good luck.
I have found the same ..... the alignment used can also have a significant effect. Here is an example of what I was talking about above - both boxes using a 21SW152 and tuned to 33Hz - one box is 190L the other 380L. The green plot will sound good, the red will sound as Marjan described.My experience with the 21sw152's has been the opposite of Marjan's.
