So to the tech guys out there .............. Whats the difference betwee the Rcf n850 , selenium 405ti and the 18 sound nd 2060................. Loudness and overall cleanliness...

tuning

^^^summed up ans dey..lol..from what i've heard selenium louder but rcf is way cleaner never heard the 18sound..however as SSC said all of them can be very loud and clean once tuned properly.

i have the 18sound ND2060

i personally prefer 18sound drivers over RCF and selenium....the selenium was too huge to fit in my backdash and although the RCF was smaller than it, it was tsill too big...the ND2060 is neodymium so it fits in almost any application, not to mention the magnet force for the 18sond is wayyy stronger than the others

all have the same sensitivity rating of 109db which is excellent but inspecting the curves for the three said drivers...u'd also notice that the 18sound has the flattest response curve

the 18sound handles 200rms, rcf handles 180rms and the selenium has 2 power ratings, 250rms and 125rms...i would go with the 125rms as how its selenium cuz most likely the 250 is peak power in this case considering the reputation of this brand...i am hitting my 18sound drivers with 250rms each from an oleskool soundstream rubicon 502 so u know its a TRUE 250rms each them mofos getting

both the RCF and the 18sound has the exact same frequency range specs whereas the selenium is said to go as low as 400hz and end @ 18,000hz...i wont exactly trusty going right down to starting point in any of these drivers though....i'd recommend to AT LEAST start @ 1000hz to be safe

really comes down to personal choice between the N80 and the ND2060 cuz as u can see with the charts theirs really no comparison between them and the seleniums...

^^^^ i tend to prefer the N850 over the others....


i have listened to the 18sounds and the selinum and in terms of clarity and being loud....


in my opinion the RCF has the edge....

n850 all d way quality & that fine pitch u get only from rcf

cudnt say it any better :thumbsup:
