marklings—Yes, you're likely correct about digital popular music mixes being more bass heavy than when intended for vinyl media, but that's for good reason. LP discs are the product of a 1948 compromise that traded fidelity for the means to fit 25 minutes/side onto a 12 inch record. Bass response was sacrificed to reduce groove excursion, and treble was boosted to mask surface noise. Complementary equalization is introduced during playback, but analog LPs still measure poorly when compared to standard “Red Book” CD media. CDs convey a dynamic range > 30 dB better than vinyl, with much flatter frequency response, far less harmonic distortion, and near-noiseless playback, so the bass will certainly be more apparent.
And, as noted, sealed speakers will provide a smoother and more natural bass falloff than ported reflex speakers, but they won't extend as deeply. That's why I prefer to use fully sealed mini-monitor main speakers with dual self-powered subwoofers for the low bass, with the main-to-bass crossover functions managed by an active electronic crossover control unit, e.g. Marchand XM66. This makes it convenient to set/reset a desired mains-to-subwoofer acoustic ratio from a single, central location; no need to crawl out to each individual subwoofer.
