Selenium 8W4P 8" Woofer
Selenium 8W4P 8" Woofer is rated 4.8182 out of 5 by 11.
Rated 5 out of 5 by from Great for my chucheroI put two of these in a small sealed cab with a single st350 tweeter and use it in my car. they are very sensitive (loud even with low power). But when you pour on the watts and crank the volume it is simply amazing. they do NOT distort, the more you turn it up the more it wants. many people have said they can't believe such small speakers are able to get so loud, aaand Clear.

Rated 5 out of 5 by from Custom 2x8 (with tweeters) 2 way application - PICTURE INCLUDEDUsed 2 woofers per cab, ported and rolled off at 80hz (electronic highpass) and crossed over over again at 2.5kHz (passive filter network, LR 12dB/octave). Couldn't believe the detail these provided! I heard things in music I have never heard before with other drivers.Running 300 watts RMS per cabinet for DJ/Livesound. Amazing output for such a small cabinet!Selenium makes great drivers!!!

Rated 5 out of 5 by from Best 6" speaker by far!!!I've been installing these in cars for at least 6yrs+.. The sound that comes from these little guys is unbelievable when putting the right amount of power on them.. They also sound great with 30-50 watts too..Great speaker!

Rated 5 out of 5 by from Great Woofer For The MoneyThis is one great woofer for the money, has a great midbass/midrange performance, and really brings the vocals out great in music smoothly but still loud, i'm using 6 the of same selenium 6" woofers and 4 of these 8s in a car audio setup, i played with them with 30 watts and they still put out great sound for the small amount watts i was surprised, but now i have them with 125watts and man do they sound off and still keep as smooth of sound as they did with 30watts going to them
