So i've been reading up on horn placement and there seems to be an actual bit of aiming for horns. It's not always about getting them as deep and wide as possible, but more of making sure the PLD between the driver side and the passenger side is the same to opposite ears of the person driving. And something along the lines of aiming the line between the middle of the throat and some point on the horns to aim at the opposite side of the car.
1:15 on this video explaining it. https://www.youtube.com/watch?v=sdEX...8DB575&index=3
I've never really understood the whole point of PLD in regards to ITD and IID in a biased side eq and reflection arena like a car. Even with exact PLD of the voice coil, you are still going to have massively different reflections for the frequencies those drivers are playing and i am sure the different arrival times of those Different reflections per side, are going to severely screw with your brains ability to figure out wtf its hearing. That and those different reflections are going to cause huge eq differences so you'll have to eq one side to sound better anyway which means the whole two seat idea will be defeated in the first place as one will always be far superior.
Maybe i am just arguing the pointlessness of a 2 seat system without upmixing and a center channel...meh. Lets not go there.
I am also confused on the whole 3 way front stage + sub, in a horn system. If your midbass are in kicks and mid-range in doors and horns against the firewall. The midbass and horns are aligned distance wise pretty closely but any info the door mid plays is going to severely screw with the stage. There is also the issue of different dispersion patterns of cones and horns, even under beaming.
A 3 way is to keep that IMD(??) or excursion related distortion out of the lower mid-range but it seems to be at a trade off of introducing a lot more issues that having another driver would add.
The ES horns are designed to throw energy at the opposite side of the car by having the long side of the horn follow the contours of a typical dash but the installs i see where the end of mouth is flush with the firewall(motor in engine compartment), or even just way deeper than would be vertically-ish flush with the dash. They all seem to kinda defeat the purpose of the design of that horn. The energy isn't following the lines of the dash anymore. They are just playing under the dash and having who knows what reflections. The long side of the horn is playing directly into the dash and not using the dash as a guide at all.
So my questions are.
How much aiming should actually be done with a horn? Is it just a matter of burying it as deep as possible and say fuck all to dash contours, or is it better to have the motor not as deep but really use the design of the car and horn in unison to make smooth transitions?
In a horn install. Is it really better to have a 3 way plus sub, vs a 2 way+ sub?
A 2 way system would have a large format midbass that plays to 1200hz, with a hlcd playing up from there. Both drivers are pretty damn close to each other's path length. You deal with the added distortion of IMD(i hope im using that correctly) but you gain a more cohesive wavefront, but perhaps lose in the realm of beaming. It also justifies the price of say ES $700 car focused horns.
If you add a 3rd driver per side. You can either put the midbass or the mid in kicks. I'd assume that the midbass in doors and mid in kicks would be the better option, but then your install gets far more complicated because you now have to build an enclosure big enough for a large format midbass driver...because absolutely F%$# doors as enclosures.
The stage should be pretty good because both hlcd and mids drivers are pretty deep but you now have 2 cones drivers, and 1 HLCD, per side. Beaming is far better accounted for and everything will be playing below beaming, giving you a better stage and far far less location ques. The downside being that the whole thing seems like a huge amount of money for whats essentially a tweeter that plays down to 1200hz and Its REALLY hard for me to do so much install and shell out any decent amount of money for a mid that only plays say 150hz-1200hz.
