mmmmmmm so many sushi for me. ... *munch munch munch* yumm....


speaker RMS rating is a guideline to you on how much power to feed them.
Another spec to look at is the sensitivity rating, the lower sensitivity
the more power you need to put to it.

Disadvantages with driving a high power handling speaker with a low
powered amp? It would sound soft, and you`ll tend to up the gains on the
amp to make it sound loud enough. More often than never, people push their
amps beyond it`s capability thus causing it to clip... in the long run
your amp and speakers r going to fry.

High power handling comps tend to sound out off control or muddy, if not
given sufficient power. The amp is not able to drive it to it`s full
potential. In other words it don`t perform as expected. But does not
necessarily applies to all components. Some would play happily even when
given less power.

upesh: Preferably we want to the amp's RMS to be higher than the speaker,
but this is not a necessity. Sometimes, lower but close to the speaker RMS
also sufficient.

If the amp's RMS is too low, then chances are that your speakers are
underpowered, and may not play accurately. Underpowering your speakers can
damage it in long run.

Wah.. so much info gained today...So what speaker rating would you
recommend if i were to use one set of components and a woofer using the
amp specs below.

4x75W RMS at 4 OHMS. 4x150W Max at 4 OHMS
2x300W Max at 4 OHMS Bridged. 4x125W RMS at 2 OHMS
MOSFET Switches to Maintain Rated Power Over A Wide Range of Battery
Voltages
Stiffly Regulated PWM-Type Power Supplies
2 Ohm Stereo Stable Operation
Stereo, Bridge and Tri-Mode System Application Compatible
Variable Input Level Controls For Each Pair of Channels
Variable High and Low Pass Crossover Controls
Thermal and Speaker Short Protection Circuitry
Power and Protection LED Indicators
Bass Boost Circuitry
Nickel Plated Power, RCA and Speaker Connectors
High-Efficiency, Heavy Aluminum Heatsink
Bass Boost Remote Control
Bridgeable at 4 Ohms
THD: <0.04%. S/N Ratio: >90dB
Channel Separation: >65dB
Freq. Response: 10Hz~35KHz, 1dB
Fuse: 15A x 2
Dimensions: 9.82"(W) x 2.34"(H) x 11.46"

basially the speaker RMS rating is a guide to protect the speaker from
frying them with too much juice. typically efficiency rating means how
easy the speaker can be driven. as we pump in more juice to the speaker
we are increasing its spl.

try to think about it if an amp is stated to do 100w RMS per channel does
it mean we are constantly pumping the full 100w RMS?

happy icing.

Tumpang thread...

My comps are rated 60W RMS. My amp is 50W x 2. Playing at moderate to
moderately loud is okay. It's when I want to play real loud that I start
to hear some inwanted "vibrations" in the mids. Example is Nora Jone's
vocals starts to sound like she got phlegm in her throat.... due to amp or
speaker??? Or both??? Alamak, suddenly see more $$$ flying by! Big Smile
