**TWO WEEK UPDATE**
I have had these RSD's in for exactly 2 weeks now. i must say, they have to be heard to believe! they really live up to all the hype they get on here. after 2 weeks of playing with tweeter angles, time alignment, crossovers, and the EQ on my Pioneer deck these things(and my whole system in general now) sound absolutely ammmaaazing IMO.
like i have said before, i have not used a lot of different component sets in my time so i might not be the best person to give a review but for the price or even maybe 2 or 3 times the price these things are awesome.
the mids and highs still sound nice and smooth but also very detailed even when played very loudly, and the mid-bass, MY GOD the mid-bass is insane. the mid-bass seemed to be getting louder and louder as time went on, at first i had 80hz and 125hz boosted a good amount on my EQ, not anymore. i am constantly turning off my sub just to hear what they sound like with out it and several times i have forgot to turn it back on thinking it was already on. i don't have my sub turned up to extreme levels though. i'm trying to go more for SQ than SPL, so no extreme bass for me. i have also played the rsd's for short periods of time in full range at pretty good volume levels and they handle it perfectly fine, no distortion or bottoming out. even when i have them crossed where i normally have them they can shake all three mirrors in my car pretty nicely. with the sub off you can still feel bass drum kicks in your chest, it's really amazing that these little guys can make this much bass. they truly have to be heard to believe.
in my case they didn't really need a lot of EQing IMO, just some slight changes here and there. i have messed with settings quite a bit and this is where i am at right now. i have 315hz cut by 1(there seems to be a decent peak there), and 2k and 3.5k also cut by 1, and i have 31hz boosted by +2, and 50hz boosted by +1(for the sub), and 80hz boosted by 1, and 12k boosted by 1.
i have the rsd's crossed at 63hz at a 12db slope and the sub at 50hz at a 12db slope as well. the rsd's have plenty of low end extension which allows me to do this. it really brings the stage forward when you can cross the fronts and the sub this low. in certain songs that don't have a lot of low low material my sub is hardly even playing.
