Im looking for Speakers/Sub to play rap mostly

If you need bass, then get a subwoofer or two, in my opinion. The monitors can be whatever.

As one who manufactures both home audio and pro audio speakers, and does so with pro audio drivers, in my opinion they are not necessarily whole different ballgames.

One reason to consider speakers that use prosound-type components for demanding home audio use is the freedom from thermal compression. Thermal compression occurs as the voice coils heat up and the resistance rises, and can rob speakers of two or three decibels on peaks. This compression of the peaks reduces the liveliness and emotion that should be in the music, because musicians use dynamic contrast to convey emotion. Typically mild thermal compression sets in at about 1/10th the rated power, and by the time we get to 1/2 the rated power it's pretty severe. By using drivers that will be seeing less than 1/10th their rated power under home audio conditions, we preserve the liveliness in the music.

However if you do not want prosound components, the Legacys you mention are a good candidate.

Like most pop oriented music rap doesn't really have much deep bass (sub 40Hz) so subwoofers aren't really necessary. As said above by Audiokinesis there really is not that much of a difference between home and pro requirements. What differences that do exist (robustness, volume output, low distortion) favor the pro side. The better home speakers can do subtlety and refinement better. Rap music isn't about subtlety and you said you wanted something frickin' loud. Do the math and see how it adds up.

ok i meant loud enough to seriously rock out, not throw a house party, sadly once you get the fancy stuff those days are gone. But you pointed exactly what I meant, Rap does have some deep bass but alot of it is focused in the 70-120HZ range which to me seems like i would need an extremely fast and power hungry bass woofer in the speaker that can handle as such as its extremely electrified and processed music

Second off youve driven down the street and heard that jerk who blasts his music to the point that hes shaking his car. Thats not cool in public but at 60 on the freeway you aint bothering noone. Its more a question of a speaker that can play all music well and handle rap and do great. as I said we dont just listen to rap, but if were gonna build our systems its gonna be different than my dads awesome SET setup which is great and beautiful but it only works if your going for what hes going for, I went with a Conrad Johnson PV11, MF200 and a pair of B&W Matrix 804's so far.

We like music just want something can pound too, while still making a guitar sing and still being able to pass the audiophile gene down to our kids (Im only into this because it gave me and my dad something to talk about and go figure I really got into it). And for the record my favorite piece of gear ive ever owned has been a conrad johnson Premier 11A.

thinking about it how a would a speaker using the scanspeak 18w45K? or something similiar in name the awesom 6.5" woofer with the spiral that just rocks work?

Oh also the C46 has tone controls which can give I wanna say 12 or 15DB of boost thanks
