Welcome!
Most perspective of you to realize your room needs help with bass, as virtually every residentially sized room does, yet the human ear easily acclimates to the inherent bass peaks/dips. And full range speakers only make matters worse in the direction they're facing. It's long been recognized that the best position in the room for generating bass versus mids/treble do not coincide, making full range speakers a flawed concept (plus the consumer pays for the lumber, veneer, shipping, and then has to pay for all that again when selling them on).
Suggest reading Floyd Toole's "Sound Reproduction" 3rd edition. It's the consummate audiophile primer for learning how speakers behave in-room. One of major points covered is how every room has huge bass peaks/dips. The ways to fix that are: 1.) Having the proper room size (bigger is better) and shape (following Fibonacci ratios is a great start); 2.) Measure and remeasure the room at each step along the way with REW (Room Eq Wizard) or Dirac; 3.) Use of 3 or 4 carefully placed subwoofers; 4.) Effective absorption (look into GIK here at Audio Circle); 5.) As a last step apply the REW/Dirac corrections being careful not to boost narrow/deep dips that can cause amps to clip and damage speakers.
Modern speaker design has been focusing on active design (low voltage input to sophisticated crossover which feeds one channel of amplification per driver) for undeniable design, cost, and sonic advantages. Which is why active speakers are used for nearly all recording, mixing, and mastering. The latest concept is the use of controlled directivity (most often seen with large wave guides surrounding the tweeters) which helps the speakers sound the same from room to room. Go to audiosciencereview.com for a sampling of speakers with a focus on controlled directivity and soundonsound.com for professional reviews of active monitors.
