not sure if I should post here or the head unit processing forum so sorry if the wrong place I did a forum search with the word active with no real results I am going to be purchasing a 80prs by pioneer here pretty soon and am very intrigued on what exactly active is does anyone have any good quality sites you could link me to with good information not common rumors or otherwise so I can begin my journey of discovery I don't mean to try and be spoon fed but we all know google isn't the most credible source so I would like to get credible sources from the experts first then after I research those and learn something then I will probably come back to this thread and pick your brains im not for sure saying I want to do active I dont even have any idea what it would sound like though I figure why not learn a little more and try it out and pray to god I love it and if not ill try something else lol

 

any help is appreciated as well as opinions comments or otherwise dont worry I wont get butthurt like most if you give it to me straight or tear me up for not googling first

Simply put.

Your sub should only play bass.  These are low notes.

Your tweeters should only play treble.  The are the high notes.

Your mids should only play what the tweeters and sub aren't.  These are the middle frequencies.

 

Two different ways to do this:

1) Utilizing a passive crossover.  These are non-powered electronics that will cause the frequencies to roll off at a selected design point.

2) Utilizing an active crossover.  These are powered electronics that will cause the frequencies to roll off at a selected design point.

 

Considering all GOOD passives incorporate some sort of eq & level balance this also needs to be mimic'd in the active world.  Normally this will mean some nice equalizer to go along with the crossover.  A non-eq'd active setup will sound a SHIT ton worse than a passive setup that is designed well.  Basically when you choose active, you are thinking you can do a better job that a marketing $ limited engineer.  This requires an ear and a lot of patience and of course is completely customizable to your tastes.

 

Easy choice if you have a great ear and are capable of searching like crazy, doing a ton of technical reading, and generally really are passionate about music.  Active all the way then.  If you aren't the above the choice is also easy and not the same.

Could you post some "general" crossover points for those three segments?

I love the idea of active then I like my music in very specific ways I like my country to sound one way rock another as well as anything else so customizable sounds awesome my ear im not to sure about im not sure if I trust it but I assume with a little bit of practice I can figure it out from what ive found so far you use the low pass filter on the sub to block any notes above a certain hertz as you had said as well as low and high pass for the mid to restrict frequencies then the high pass for the tweeters now as a question I have seen mention of 2 way and 3 way active which is superior and if they are equal what are the factors that would cause a person to decide one over the other?

 

and I love music and need a hobby that doesn't involve changing out my stereo components every week because it seems to make me broke so I love the idea of changing installation and deadening and settings to satisfy my need for change and pursuit of making it better... I get a little obsessive about certain hobbies

 

now Ive read in my research time alignment crossover slopes and roll offs are paramount is speaker placement a huge deal or can it be overcome by proper install and settings I just have soo many questions lol I wish there was a sticky with a comprehensive guide or knowledge base or something on this subject because it seems like a hell of an endeavour

I love the idea of active then I like my music in very specific ways I like my country to sound one way rock another as well as anything else so customizable sounds awesome my ear

 

Keep in mind a poorly tuned active setup will sound worse than a moderately well tuned passive setup.  There is a balancing act between knowledge, skill and sound.  And it will take considerable time to make an active setup actually sound good.

 

what ive found so far you use the low pass filter on the sub to block any notes above a certain hertz as you had said as well as low and high pass for the mid to restrict frequencies then the high pass for the tweeters

 

A crossover isn't a brick wall.  It doesn't block frequencies above or below the crossover point, it attenuates them at a certain rate based on the slope of the crossover. 

 

now as a question I have seen mention of 2 way and 3 way active which is superior and if they are equal what are the factors that would cause a person to decide one over the other?

 

 

There are a lot of factors.  One could nearly write a book about all of the various factors, advantages and disadvantages.  Short story is that one is not better than another.  They each have their own purpose and role.  It depends a lot on goals, skill and knowledge in tuning, restrictions, budget, personal preference. 

 

If you are just starting out (which is appears you are), then with either active or passive 3-way is a bad idea.  It takes more understanding to properly setup even when passive.  Active would have you pulling your hair out.

 

now Ive read in my research time alignment crossover slopes and roll offs are paramount is speaker placement a huge deal or can it be overcome by proper install and settings

 

Speaker placement is part of proper install.  And no, not all speaker placement issues can be overcome by tuning.

 

I wish there was a sticky with a comprehensive guide or knowledge base or something on this subject because it seems like a hell of an endeavour

 

It would be too long.  Pick up some good acoustic related books and start reading.

There aren't any.  Speaker/install/etc dependent.

 

Seriously, just about every "rule" could be broken under certain circumstances.    

wow my curiosity has became interest I think I am really going to look into to this worst case scenario it sounds bad until I get my head right either way I like the idea of the challenge and with how helpful yall are I think im going to try my two channel active set up I think I may just keep bumping this thread with questions and as I buy parts start a log because I have a feeling this is going to be a long process

Your getting advice from people who really understand their shit.

exactly why I greatly appreciate their input and am confident in pursuing this venture any added info of any type to help me on my pursuit of awesome sound would be appreciated tips tricks etc..

Exactly what I did

umm I would love to read your input but it doesn't show for me in english

Сей вопрос касается скорее студентов, ищущих подработку, выпускников и тех, кто задумался о переквалификации, нежели тех, который уже давно и успешно трудится сообразно той специальности, которая записана у них в дипломах.

Студенты, решившие встречать работу, чаще всего руководствуются одной из двух целей: либо они хотят заработать денег и обрести независимость, либо желают приобрести попытка работы по специальности опять прежде окончания высшего учебного заведения (искренние поздравления тем, у кого удачно совпали обе цели).

В первом случае будет хороша любая подвиг: и барменом, и продавцом, и официантом, и промоутером. Размер зарплаты довольно напрямую зависеть через трудолюбия и отработанных часов, а навыки работы в команде и общения с людьми в будущем пригодятся на всякий работе.

Сколько касается дальновидных студентов, то в первое время, когда они будут подвизаться по специальности, о высокой зарплате лучше пренебрегать: никто не будет платить больших денег сотруднику без опыта. Однако сообразно окончании вуза усилия окупятся.

У тех, который решил переквалифицироваться, — свои причины (либо материалистические — желание избегать из неприбыльной сферы, либо идеалистические — встречать работу сообразно душе). И в том, и в другом случае должен проанализировать свои сильные и слабые профессиональные качества, а потом уже определяться с выбором новой работы.

google translate, umm i dont think hes talking about crossovers

umm I would love to read your input but it doesn't show for me in english

It's spam.

The time,effort and learning curve are very well worth it in the long  run when diving into active.

Start small if you go that route.  Expect you will blow a driver or two so don't go nuts on spendy ones and also expect that for a year or two your car will sound worse than if you just bought something off the shelf.

Why would i blow drivers? And yea i figured as much its slightly intimidating from how complicated it sounds though i think im gonna start with this set of 65 dollar pioneer components i found and go from there do you think it would be a good idea to hook them up with the passive crossovers first hear the sound then attempt active and try to match the sound then customize to my liking so i can have a slight base line to start or what is the best way to start

Because you'll confuse something along the way and it'll happen.

Oh ok i understand now should i start off with a prebuilt component set and just remove the crossover or purchase a woofer and tweeter seperate? Also what do you think of my baseline idea?

You're going into troubles !!! j/k
Good luck

I would like to try a passive setup, once, but I don't have time to tune anything to often, and I don't like to play with settings.

So, I just bought a good component set and  tried to install it properly in my front doors. I still love the sound, 7 years after.

 

 

Oh ok i understand now should i start off with a prebuilt component set and just remove the crossover or purchase a woofer and tweeter seperate?

Separate.  Better quality and wider availability of drivers at better prices and without wasting money on a passive crossover that you aren't even going to use.  Half of the advantage of active is less limitations in driver selection.

 

Now that doesn't mean you can buy any mid and tweeter and expect it to work well.  You need to select drivers that will work together.  And as M5 said start out with less expensive drivers.  Helps ease the burn if you mess up and blow something by accident, and it helps you learn your preferences with less out of pocket expense. 

Awesome the advice is so helpful for individuals what brands do you recommend and where to purchase from

Depends completely on the install.  Mounting locations, aiming, musical preferences, processing, capability, yada yada.  

 

Either way, you need to make a plan on where.  

Wow there is alot to this sorry ive been asking so much im still actively using google though there doesnt quite seem to be a wealth of knowledge like asking here is
