ano ba ang diff ng 2 way sa 3 way na speakers..
There are 2 general type of speakers, components also called seps or seperates and coaxial speakers.

Components consist of 2 or more speakers seperated from each other. This is a set that comes with a tweeter and a midrange or midbass speaker and a crosover. Coaxial speakers, the tweeter is mounted on top of the midrange or midbass. This is the most common form of speakers.

2 way speakers consist of a tweeter and a woofer. 3 way can be a tweeter, a midrange and a woofer. Some 6x9 3 ways are tweeter, super tweeter and a woofer. Generally, 2 way component system is good enough.

ano ba ok for seps and mid range?
There are lots of good brands it all depends on your listening preference and budget. Best advice listen to other systems 1st before buying. This is called "audition".

For budget meal, popular brands are Targa, Aura, JBL entry level, Ryan Audio, Infinity etc. Prices can start as low as 1,000 to around 5,000. Almost all speaker makers have entry level speakers. I personally use Ryan Audio Q series and I'm happy with it.

Bigger budgets will open up a whole new level of listening experience.

kasi may nabasa din ako na 3 way set up parang may seps na 6 inch then isang 4 inch with tweeter
This is called a 3 way component. More flexible but harder to install as you will have to find space for 3 drivers instead of 2. Generally more expensive than 2 way components. With a good installer and system, this can sound teriffic.

need your answers.. im planning to add a simple audio set up... pero lookign at sq.. thanks sa mga sagot boss!
Audition! Canvass! Whats your budget? Good installers are expensive, but worth it. For me, car audio is 50% install and 50% equipment. A good installer can work wonders. They can make even a all Targa system win in competions. While a guy without experence can ruin the sound of a very expensive setup.
