Hello FM's

The post is to make a clarity on the common facts which are consider when someone like to Buy first speaker or Upgrade.

1.Minimum Watts- The Amplifier should have atleast 2*power of the minimum recommended watts of speaker.

Eg: Speaker Minimum Wats is 30 and Max is 100, then the Amplifier should be atlest 60 Watts per Chanel.

2.Sensitivity- High the Speaker is Sensitive they can be driven with less watts amps,

Assumption : 99 DB Speaker can emit 144 db with only 32 watts,where as 86 DB Speaker needs almost 500 Wats per channel.

3.Ohm- some basic understanding. Low the Ohm will load would heat up the power unit(Transformer) of Amp compared to 8 Ohms.

8 Ohm 89 db Sensitivity speakers consume 500 watts for 114 db.

4 Ohm 89 db Sensitivity speakers Consume say approx more power than 8 ohms.

So 8 is better and 4 needs more power.

Is this the reason the SUBWOOFERS are more power HUNGRY?

Note: The wats needs to be DOUBLED for feeling the INCREASE three DB.

4.Numbers of Drivers- Still need a clarity.

2*8 ohm speaker=4 Ohm Load= Double the power required than Single driver.

1*8 Inch driver at 89 db Sensitivity needs 32 Watts for reaching 104 DB ?

2*8 Inch Driver at 89 db Sensitivity needs 64 Watts for reaching 104 DB?

I understood that MORE DRIVERS=MORE Watts consumed= Less OHM.

So DOES More drivers= Good Quality of sound and the power consumed are really worthy?

If the More sensitivity Speakers are easy driven with low power amps then Why we cant find much Speakers with More sensitivity now a days compared to say 70's and 80's or before.I have seen few Vintage speakers they are really with High sensitivity. But

Please share your opinion's

Note:

All, All the above is my assumption\understand by reading and not TESTED LIVE ,So kindly correct wherever, I that i could correct my understanding.
