Planar Magnetic Speakers??

[spwath]

So I didnt know these existed. Are they simmilar to planar magnetic headphones in the advantages and such? Why are they not more popular?
Was just browsing craigslist and found these, not going to buy them due to $$, but just interested in this idea.

its the same concept as a ribbon tweeter

but ribbon tweeters are only good for high and ultrasonic frequencies

i bet these speakers have bass just as good as a laptop

But planar magnetic headphones have quite good bass.

It will have good bass because unlike a ribbon tweeter which is no bigger then a couple inches this is huge and it does the bass well.

Personally i think those modifications ruin it. If it wasnt modified and was still with all the original parts like the trim and the canvas I would be throwing money at the owner but it doesnt look in that good of nick too many modifications for my liking.

yeah, because they are like an inch big

take some headphones and hold them a foot away from your ear and you will see that you can still hear them but the bass is gone

thats because it doesnt have enough SPL to make the low frequencies audible

how large it is doesnt make much of a difference when its excursion is barely a millimeter

Of course there no sub woofer so there not throwing out the sub 125hz, but they do produce good low mids.

There not popular because most the time there massive. But a similar style of speaker Distributed mode loudspeakers where some drives vibrate a large canvas produce a similar sound but, they also arnt very popular but they are going to be because of the the war on making TV screens thin, so currently television screens are starting to get so thin that now the speaker is the limiting factor on thinness so a lot of research is going into making it so that the tv screen its self is the speaker by using DML speakers I saw some people attempt planar magnetic but it doesn't work because you still have cables in the way.

pretty much any regular speaker can do 50 or 40Hz at -3db

125 is extremely high for a speaker that size

that would just sound horrible

-3db is a bit of understatement most speakers by 40Hz are down by 10dB and by 30Hz they can be down by 30dB. But dont think of this speaker the same way you think of a normal speaker it works differently and produces a completely different sound.

lol wtf

all speakers work the same, they move air

a ribbon tweeter is a different kind of driver, it does not magically make the sound any different

or do you think that you can hear spirits and ghosts through this speaker or something?

You dam well know what I meant, It works differently then a normal speaker in the term its not a single round driver moving back and forth.

no, now its a flat driver which moves back and forth a lot less

 

thats why bass response sucks so much for this type of speaker
