Accurate speakers for a verity of genres?

Hello guys – I’m looking for L/R speakers to fill a 15x15 room – the budget is <4K (new/used). I’m not much of a PC user and was recommended by a good friend of mine to post here for advice.

I don’t have subs yet, so wanted something that could extend into the mid 30’s if needed. I will get subs next year so it’s not a big deal. My background is in music (have a degree from NYU) and come from a family or producers. Being that the speakers will be in my living room, I want something nice looking, and also capable of home theater usage and powered by a receiver.

I’m pretty young (under 26) and my musical tastes are leaning towards the more compressed side. Pop and some rock if I’m feeling casual, house or funk if I’m reminiscing and “real” hip-hop if I’m looking for stories or lyrical material. All mood dependent. I’m ‘classically trained’ and very critical in many genres’ being exposed to them my entire life though. Unfortunately, I do not listen classical music in my home although I do respect it. My instruments of choice are typically percussion based rather than string based and I really like both hard hitting bass and rolling basslines - but clean bass. Never boomy despite the musical choices.

Strange eh? I enjoy an accurate sound, that isn’t harsh in the upper band. Perhaps I have sensitive ears nowadays. I know to appreciate flat req response, and smooth off-axis response, great crossovers, etc. Now the question is – Where do I begin looking? Thanks for your time!!!!
