Why big driver

I love photography, shot some too!

for poor man's dream to be sucessful, I had to buy older lens which means quite old lens actually. but they come with fast aperture and fixed focal length. that helped me in toning my eye to reselct my area of composing correctly for the lens I have on my camera body.

Simalrly to conceive and achieve my dream I had to rely on cheap speakers. Means Public Anouncement speakers. Actually, later i found out those big PA drivers of those big speakers actually creates live programme like atmosphere at home.
Plus they generate a life like sound reproduction, a bit larger than life actually for some cases.

These PA drivers have quite good value of SPL. Mostly greater than 93 dB/W/m. Ahuja drivers has minimum of 97 dB/W/m. Means a run off the mill branded speakers of 89 SPL will struggle to produce sound with a 10 Watt amplifier, where these driver will fill your room.
Plus a larger diaphragm generates a pitch that emolute those musical instrument.

Try listening any song through your mobile and then listen the same song through your car speaker inside your car. You will understand what I meant.

Size does matter.

Secret of open baffle

There is nothing secret really, rather it is an illusion.

Illusion caused by delayed music that comes from the rear sound of the same driver. sound from the rear of the open baffle (OB) speaker gets reflected from the front wall (of the listener) and reaches listener bit delayed.
In presence of the sound projected by the front of the driver, this delayed sound creates a lovely 3 dimensional sound stage.

You get quite a depth depending on the music, room and ofcourse your speaker and amplifier set up.

What is a reproduction then?
Just an illusion of the recording studio or the live programme.
