M-Audio BX5 Carbon Review: Affordable Studio Monitors That Pack a Punch

00:00:00 - 00:00:25
I’m S.W. Hammond, reviewing the M-Audio BX5 Carbon Black studio monitors—the good, bad, and overlooked aspects. Includes a sound test! Studio monitors need calibration; check my setup video for tips.

00:00:25 - 00:00:59
My office doubles as a studio for novels, audiobooks, podcasts, YouTube videos, and multimedia. Monitor placement isn’t ideal, but it works for my needs—more on that later.

00:00:59 - 00:02:32
BX5 Carbon specs: 1-inch silk dome tweeter, 5-inch Kevlar woofers (not carbon fiber), 70W bi-amped (40W woofer, 30W tweeter), shielded, XLR/TRS inputs, rear port, volume knob, acoustic space control (-2dB, -4dB, flat), power switch, 110/220V selector. Comes with foam padding, user guide.

00:02:32 - 00:04:46
I’ve used these for eight months since Black Friday 2018. I’m not an audio guru but have experience as an assistant engineer on 15 albums, at Sony Music, and in live sound. These weren’t my first choice—I wanted 6- or 8-inch drivers, front ports, more power—but a $100 deal was too good to pass.

00:04:46 - 00:07:20
Pros aren’t the target for these as primary monitors; they’re for creators like me. I planned to spend $600–$800 but took a chance at $100. If they failed, I’d use them in the garage or resell. They’re not for pros mixing albums but great for secondary use or multimedia creators.

00:07:20 - 00:10:14
Treat your room before buying high-end gear—acoustic treatment trumps equipment. Budget gear has improved dramatically. BX5s use Kevlar, not carbon fiber (despite the name). Kevlar’s precise but harsh, unlike paper or polypropylene cones, which are warmer but less detailed.

00:10:14 - 00:15:11
Kevlar’s clarity is fatiguing at first—sounds pierce rather than blend. Break-in (24+ hours over weeks) and ear conditioning help. Initially, the BX5s were wince-worthy, but after two weeks, they mellowed, and I kept them as daily monitors. They’re not bass-heavy; you’ll need a subwoofer for low-end mixing.

00:15:11 - 00:18:36
Mid-range and tweeters shine—balanced, accurate, no complaints. Compared to JBL, PreSonus, or Mackie, it’s subjective; features or price decide. Rear ports exaggerate bass against walls, less ideal for my setup, but sound-absorbing material helps. I use a repurposed 100W sub for casual listening, off during serious mixing.

00:18:36 - 00:23:07
Soundstage is excellent; imaging lets me pinpoint instruments in the sweet spot. My elevated setup (above monitors) creates an ethereal effect I love, despite purist objections. It suits my desk with large screens. Rear ports are a drawback if against walls without treatment.

00:23:07 - 00:26:18
I built custom cradles for these on gas-spring arms—video coming soon. I’m happy with the BX5s; they meet my multimedia needs. Clarity is impressive, revealing subtle details like page turns or vocal breaths, improving my content creation.

00:26:18 - 00:29:49
At $300/pair, I endorse them for non-pros. They’re well-made, perform flawlessly post-break-in, and don’t hold me back. Recommend a subwoofer (80–120Hz crossover) for music mixing. Small footprint (10x7x7.5 inches) fits most desks.

00:29:49 - 00:33:14
My studio is treated with absorption panels and diffusers, critical for sound quality. BX5s excel in this environment for audiobooks, podcasts, and light music composition. Calibrate monitors before use—my video explains how. Equalizing volume is essential for soundstage.

00:33:14 - 00:36:15
Recap: treat your room, be honest about needs, calibrate speakers. Sound test uses a Dayton Audio EMM-6 mic—flat but accurate. Results vary by your setup (laptop, earbuds, studio). Like, subscribe, comment your thoughts on the BX5s!
