Engine capacity Vs Curb Weight has to
go hand-in-hand as we know in automotives”
Here it’s the Amplifiers Versus
Speakers that makes it simple to understand right?
But let’s see how much technical we can
travel through this to get it right for our understanding!
It is highly important to understand
this, while we graduate to use this set up even as an amateur music lover or
audio fanatic!
First things first: Impedance, Power
handling and Sensitivity
Impedance of Amplifiers and
speakers are mentioned in Ohms between 4 to 8 Ω.
Unless your Amplifier and Speaker are down to these ranges it’s not recommended
to drive them at higher volume levels which could result in failure of your Amp
or Speaker!
Power handling is usually mentioned
in wattage and some do not mention the peak power of the speaker but it’s
better to go by the RMS / nominal power output of your Amplifier and your
speaker
Monoblock
Stereo Power Amplifier India | Power in RMS
mentioned is the Root Mean Square, alright I mean the effective value of sound
waves delivered whereas peak power is utilizing incoming voltage to its maximum
capacity possible towards the sound waves which may not be as natural or clear
as heard from the actual recording. While some people may still love the ground
shaking or heart hitting powerful bass and shrills it’s not often advisable or
acceptable to the majority out there.
Therefore, the Wattage output of
Amplifier cannot stand at 50Watts per channel and we end up hooking a 150 watt
per channel speaker set up to it just because we liked that speaker and
couldn’t upgrade to a better Integrated amp or processor which supports its
actual power.
Sensitivity is usually looked by
us independently but we should ideally take it together with the overall frequency
response range in Kilohertz that usually ranges from 20 Hz to 22,000 kHz.
Sensitivity means how easily an amplifier can drive the speakers. Low
sensitivity speakers need bigger amps as higher sensitivity ones need low
amplifiers. Anything above 90 dB is good enough for home usage.
Some Knowledge on Speakers and
Amplifiers...
Speakers:
Low, mid and high frequency ranges are
catered by various combination of the drivers. There are several driver
variants to choose from and each one has its unique characteristics utilized by
an engineer.
While not missing out on the above
specifications we may choose from a dynamic speaker like the two-way/three-way
bookshelf or floor standing speakers or electrostatic ones with lower
distortion trends, ribbon, bi-polar, or horn-built speakers which are a little
more efficient in nature.
Amplifiers:
While frequencies are similar for our
knowledge here the amplifiers used in building subwoofers or speakers or even
externally used Stereo or multi-channel amplifiers are classified into A, B, D,
G, H and A/B.
Dedicated transformers for separate
channels, high-end monoblock, vacuum tubes, transistors, Ultrasonic, Wide-band,
and high gain electronic amplifiers are some variants in build classification.
Each has its unified response ranges but from sound perspectives they may have
minor differences while the high-end ones carefully built can show a major
difference in terms of soundstage and definition of each frequency reproduced.
Integrated Amplifiers can be a
readymade option for those who want limited components yet a great
amplification and power output for their good to great sounding speakers as
they can supply enough power to the speakers
While some may use an excellent processor
and amplifier built in their high end so called AVR and be happy with it and as
long as that works for their needs it is still okay.
Conclusion:
So, squeezing all of these in a
nutshell, an Amplifier should carry the perfect sound signals and hand it over
to Speakers at any given volume level with ease and without losing the timbre
of the sound.
Have a great sound!
