3 way speakers

Specifically for LAs

yes i want specifically array simulation. i see no point in simulating regular boxes - i know how they work. the point is to to experiment with things so it gives you an intuitive feel for how it works.

that's what happened with HornResp - i played with it until i started to get the feeling for how horns and boxes respond. now i don't need to model anything i can just intuitively know it.

Yeah this is great super power! Applies to all kinds of things, not just audio. Sometimes it bites back and intuition gets it bit wrong. But yeah, the main concept is then available as instasimtm in brain.

I recommend VituixCAD, ideal drivers available, million tests at fingertips much fun for hours on end 😀
 
Who brought line array into here?

Danley guys like to talk about imaging not because it's so important but because it's what their system is good at.
I get what you were trying to say but surmising that imaging might only be important because ones system just so happens to be good at it, is as they say, wild. lol
 
I'm in the final stages of building my first pair of 2 way speakers and already thinking what next. Ive built plenty of subwoofers. When I started this 2 way project it was originally going to be a 3 way but I must have heard at least a half a dozen people tell me not to go 3 way since it is a way more complex build. I reluctantly decided to go 2 way and Very glad I did. I learned a lot on this 2 way build but what I didnt learn is why are 3 way builds so much harder? Isnt it just an extra driver and crossover. Is it that much more difficult to match up 3 drivers? Anybody care to educate me on the subject? I'd appreciate anybody willing to take a few minutes to explain it to me. This forum has been a huge help for me already so thank you for that
Give a man a passive crossover and he frequency-divides and level-matches one simple design somewhat painstakingly over days or weeks. Give a man a DSP active crossover and he frequency-divides, equalizes, level-matches, and signal-path-compensates many complex designs with instantaneous audibility of adjustments. I, for one, am :note:never going back again:note:.
 
Most of the work (at least for me) is in the calculations and simulations common to both types of crossover.
For me, no calculations or simulations.
Just measurements and putting filters, crossovers, levels, and delays directly into the processor from those measurements.

A 4-way main like below takes less than an hour to measure and construct all four sections.
Acoustic responses and impulses of each section, with black trace being measured summation. 1/12th no gating.

That's a beautiful tune you're singing 111dB! :note:never going back again:note:.
 
Mark, some would argue that your method is little different as you're not taking acoustics into account either, since you don't use off-axis measurements.

I'd defend your position to a point, however, by saying that with synergy horns the off-axis performance is almost common through the crossover region since it is to a degree set by the horn.

Once I obtained DSP multiamp capability, I was able to make gratifying improvements to my best system as tuned by ear. Once I obtained calibrated measurement capability and compensated via DSP for more subtle system nonlinearities I made stunning and groundbreaking improvements as confirmed by all who have auditioned. Now I mostly just listen in awe. It's a 4-way system, btw, and feloniously inexpensive. Cheers!

going back from DSP to passive is like going back from a Car to a Bicycle.

believe it or not there is an international movement called "Urbanism" that seeks to accomplish exactly that. they are also winning. they are dismantling everything from BQE expressway in NYC to the highways across the everglades in Florida and they are putting concrete road blocks on main streets in towns all over America ( and Europe is much further along still ).

likewise there are movements within DIY / Audiophile community that reject modernity. they have likewise scored many victories against me.

in the end i have learned that the solution to them is the "ignore" function of the forum.

as Robert Greene teaches "do not recite poetry to one who is not a poet"

or "you can't wake a man who is pretending to be asleep" - Chinese Proverb

some battles cannot be won, sadly.

i have figured out a long time ago that the reason commercial systems aren't better isn't because they don't know to improve them

but because the average customer never listens to music on their speakers the same as how they never use their fireplace to heat the home - it's just there to have some expensive looking accent to their living room

this is why there are no 2-way headphones. it's not because they wouldn't be better - it's because people want headphones that LOOK EXPENSIVE not headphones that sound good.

show me one $1,000 headphone that looks cheap. you can't. you can probably find many that sound horrible but not one that looks cheap.

all studio and prosound is now 100% DSP because those are professional tools that must perform. 99% of home audio still analog not because it is cheaper ( DSP doesn't cost anything anymore ) but because amateurs fear it. 100% of car audio is DSP though, because people can't see how it is internally designed so they can't fear it.

my late grandma used to be afraid of 120V extension cords - she thought they are irradiating her with electromagnetic waves because a YouTube video said so. i tried explaining to her that there are also wires in the wall that are exactly the same but she was never afraid of those because she couldn't see them - she was only afraid of visible wires. likewise people aren't afraid of DSP systems in car audio because they are hidden, but they want good old capacitors in their speakers to feel safe ( make sure their music isn't harmed ).

you could try explaining to them that the music they're listening to passed through countless op amps and DSP processors before it was recorded but they will just be no, i can't have any OP amps or DSP - they ruin music. i can only have vacuum tubes and capacitors.

the key is to never respond to them. EVER. just put them on ignore. without ignore function i couldn't be here. they would all gang up on me and drive me out. their strength is in numbers but they can't get to you if you can't hear them.

at one point i thought i found paradise when i discovered ASR because they actually embraced DSP over there as opposed to places like this where capacitor still rules but i soon discovered that on ASR they believe all anybody needs is a 19mm silk tweeter and a 5" woofer and i don't think a single person on that entire site has ever even heard bass in their life ...

then on AVS they are actually fairly sensible ... until you try to criticize sinbosen amplifiers or dayton subwoofers or any other heaps of bass on the cheap solution. then the pitchforks come out.

and so on. in the end honestly for all the BS on here Diy Audio is still the best on the balance, probably because it is the biggest. the sheer size prevents any one group of lunatics from completely taking over the whole asylum. there are always pockets of resistance.

that said a more honest description for this site would be " the house of vacuum tube and fancy capacitor ( with a side of Danley ) "

honest description for AVS would be " the house of subwoofer walls, single digit Hz, Dayton and Sinbosen "

and actually some self-aware individual on ASR ( not me ) described their own site as a house of " plastic DSP boxes "

i will say though this is the only place where people build their own drivers and amps. which is something i don't do but i respect it.
