Accurate Nearfield Monitoring for Every Studio

JBL 305P MkII active studio monitors are a great nearfield solution for any serious audio engineer or music producer. They're great for mixing music in your DAW software, editing video, or any other task that requires monitoring accuracy. JBL designed the 305P MkII with advanced features acquired from their 7 Series and M2 Master Reference Monitor, making legendary JBL performance accessible to every studio. JBL's innovative Image Control Waveguide works in concert with refined transducers to deliver a well-defined and incredibly dimensional stereo image. Ask anyone at Sweetwater: from surprisingly rich lows to smooth highs, you'll find it easy to produce great-sounding recordings with JBL 305P MkII studio monitors.

Incredible stereo imaging thanks to an innovative waveguide

When you can clearly hear everything in your mix, you make accurate sonic judgments — which leads to better-sounding recordings. To that end, JBL applied innovative elements from their 7 Series and M2 Master Reference Monitors to give the 305P MkII truly impressive sound reproduction capabilities. The Image Control Waveguide design is one such feature, and it helps the 305P MkII present a deep, detailed soundstage and a wide, room-friendly sweet spot.

Wide sweet spot equals a better studio experience

We're engineers, musicians, and producers, too — we know you don't spend every second of your studio time in the ideal mixing position. JBL 305P MkII monitors have a broad sweet spot, which means there's less variation in what you hear when you're not in the perfect position. Especially if you have clients in the room, you want consistent sound throughout your studio, and you'll like what you hear from the 305P MkII.

Ported design for greater accuracy at low volume levels

Checking your mix at low volume levels is a great way to confirm your overall balances, but many monitors will suffer in the bass regions when monitoring at low levels. The JBL 305P MkII uses JBL's patented Slip Stream low-frequency port for accurate bass response at low playback levels. The double-flared port shape also reduces the turbulence some ported designs suffer from, meaning that bass response remains pure when you turn the 305P MkII back up.

JBL 305P MkII Powered Studio Monitor Features:

  • Next-generation JBL transducers for optimized transient response and enhanced linearity
  • Boundary EQ settings compensate for environmentally induced low-frequency anomalies
  • Patented Image Control Waveguide for detailed imaging and a wide, room-friendly sweet spot

  • Frequency response (±3dB): 49Hz–20kHz
  • HF Trim switch adjusts high-frequency output to accommodate room acoustics or personal preferences
  • Flexible connectivity with balanced XLR and 1/4" TRS inputs, +4dBu/–10dBV input-sensitivity switch, and volume control
  • Engineered to JBL Linear Spatial Reference design criteria for outstanding accuracy in any acoustical environment
  • Strenuous JBL 100-hour power test ensures years of reliability
  • Shielded for safe placement near magnetically sensitive equipment
  • Sleek, modern design provides a dramatic flair to any studio
  • Compact footprint accommodates a variety of studio spaces

Great value, and quality on par with the Yamaha HS7s

I was torn between the JBLs or the HS7s for my fairly small sized home studio bedroom but after getting a couple of recommendations and advice from fellow audio professionals, I went with the JBLs first due to pricing but also ultimately identifying only a very small minor difference between these and the HS7s that wouldn't have made any difference.

I work full time (work from home) as a sound designer and mixer for a post production company (as opposed to an at home bedroom producer/hobbyist), so I was indeed meticulously searching for the right replacement speakers, and these definitely do the trick!!

Highly recommend, especially if on a budget!!

Clear accurate sound

What I like most about these monitors is that they sound great at low volume levels. Also, since my studio space is relatively small, the Boundary EQ settings come in handy to compensate for environmentally induced low-frequencies. These monitors allow me to mix with comfort and confidence.

JBL 305P Mk5-inch Powered Studio monitor

I am an old fart, 72, and have been doing sound for 50 years. I have been a JBL Man all my life, I have spent a lot of money on JBL Speakers over my lifetime. For years my favorite Speakers were my JBL 4310 Studio Monitors, I bought used from Bones Howe when he closed the little studio at Sunset and Vine, but alas after some 60 years of use, they faded a bit, and got set aside. When I built my new system 10 years ago, I bought MRX500 Speakers, and Crown Amps and DBX Drive Racks thinking I could creat the best sound, well I haven't mastered that as much as I would like, and never really got the sound I was looking for. Now I have a Recording Truck and a Home Studio. I decided to try the self powered speakers because they are build to be tuned correctly. And WOW!, I am hearing the best sound I have ever heard in my Control Rooms in over 50 years, it just blows my mind. The Sound Stage is so real sounding it is hard to believe it is recorded. I spend hours listening to Audiophile Blues Videos on YouTube and I am just amazed at how awesome these speakers sound, and they are the lowest priced speakers in my collection! Go Figure

Incredible Monitors

I had the Mackie CR3s for the longest time due to the small room my setup is currently in. I decided I had to move my setup to a proper sized room in the house and upgrade my Monitors.

Recently, I purchased the JBL MKII 305Ps and was going to wait until I moved my setup... I lasted maybe a day?... I had to try them! Against all reason, I placed these far too large Monitors in my 5.5 ft wide by 4 ft deep by 12 ft high ceiling room and Then I tried them out... They are so perfect, I don't have to move after all! The accuracy is pristine and they are less harsh than the CR3s which are half the size! These JBLs are perfect! Somehow the close proximity technology actually works! I trimmed the LF boundary EQ to -3 and left the HF trim at 0 while setting the out to half (10 clicks or 5-6) and placing my Focusrite 2i2 Gain just below the half-way point. No further adjustments! They are perfectly flat and I can hear the highs with insanely beautiful detail! Beyond impressed!

Phenomenal

Phenomenal sound! The bass is killer, each note is so clear and clean. These can get very loud as well. Also, sweetwater is amazing, they had these monitors shipped and out the door 45 minutes after I placed my order. They arrived at my doorstep in less than 24 hours! Thank you again!
