the 4 ohm rating


im a little confused as to why buyers choose 4 ohm products.

now here's what got me thinking about all of this 4 ohm stuff.

i took a pair of mids into my rebuilders shop the other day to get new surrounds installed & we started talikng audio & he told me that about 75% of the blown driver's he takes in for rebuilding are 4 ohms & the other 25% was split between 8 & 16 ohms.

correct me if im wrong but when you run a amp in 4 ohms as opposed to 8 ohms isnt the amp working much harder to produce the inflated wattage at the lower ohms? & isnt a amp thats getting worked hard a bad thing?

the same goes for 4 ohm speakers,the 4 ohm rating only makes the speakers to appear to be more efficient & also creates the need for thicker cabeling for the lower ohm's.

i hope the answers can remain civil as i didnt start this thread to be a smart ass but i am wondering what(if any)advantages there are to having 4 ohm gear over 8 ohm gear.

take me to school here & learn me somthing because all im seeing is drawback's to owning 4 ohm gear.

ok guys,ive read all the responses & all of them were well writen but there wasnt anything that really answers my question.

most of the responses went on to further puzzle me as to why people choose 4 ohm gear when by the statements written in the responses 4 ohms looks even more like a drawback to me then ever before.

if by having your amp running in 4 ohms uses more current to run at that wattage isnt that current being drawn from the power supply(wall outlet)& isnt the increased current being drawn making the supply weaker creating the need for dedicated lines,power conditioners & beefier power cords & custom cabling.

also as C123666 pointed out with his article that running 4 ohm speakers dose not improve a speakers accuracy,reduce distortion or make improvements in any other area other than playing louder but then requires the use of heavier wiring & better connections at the amp isnt that a drawback.

im not saying that 4 ohm gear dosent sound as good or even better than 8 ohm gear but from everything i see & read is that 4 ohm gear requires alot more aftermarket products to let it reach its full potential.

once again this wasnt an attack on 4 ohm gear but i clearly see multiple drawbacks that not only shorten the life of amps but require more cash to be spent to reach top performance.

RABELAIS,excellent explaination,now this whole issue is starting to make sense to me.

i did not know that 4 ohm's was helpful in creating better bass in a smaller cabinet & it makes perfect sense,my speakers are 8 ohm & go down to 20 hz but they are absolute giants that take a ton of floor space.

thanks for taking the time to really explain this to me,the whole deal had me confused but it now makes sense.
