First Tests - Bronze BX1

"Compact; smart design; clear midrange; decent bass depth and control; good scale."


May 2013

Bronze BX1 Certified & Recommended

“The Monitor Audio Bronze BX1 looks like a high-end product.”

“Over and over, the panelists described the BX1’s sound as “flat”, but they meant that as a compliment. They meant flat in terms of frequency response, i.e., without any peaks and dips that color the sound.”

“This is an all-around good speaker. It works really well on rock, pop, acoustic music... almost anything.”

“I felt that the BX1’s tweeter was definitely the best in this bunch, the only one that showed not a trace of edginess. It was also in perfect balance with the woofer; Monitor’s engineers nailed the crossover on this speaker.”

“A neutral sound that treats any kind of music with respect. If that’s what you want, the BX1 will provide.”

Monitor Audio BX1 is a superb little speaker. Its portrayal of sound serves the music rather than enhancing the sound in a artificial fashion. It does all the 'hifi' basics (bass, treble, dynamics, PRAT and resolution) in a acceptable musical fashion. Not bad for a speaker worth £200.00

I own a pair of Monitor Audio Bx5 as well and all I can say is that the BX1s really rock. I love doing sound comparisons between the two sets and I can say that for such a small speaker they give you a large full sound with great detail and clarity, I think if i had heard the BX1s first I might not have even given the BX5s a listen as they really did it for me. Dont be fooled by their size!

Chuffed with the voluminous sound generated by such small speakers. From everything from bass-heavy songs such as "Supermassive Black Hole" to acoustic numbers like Led Zeppelin's "Babe I'm Gonna Leave You", my BX1s have never failed to prove seriously impressive.

  • High frequency level adjustment (3dB).
  • Audio match with BR-CP, Radius-CP, Climate 10 and Bronze BR and Radius Series hi-fi speakers.
  • Our innovative Tri-Grip® fixing system is easier to install than conventional clamping schemes but provides three times the surface area and a better surface seal, maximising bass response and mid-range clarity.
  • Magnetic and easily removable steel grille.

Suggested alternative

Radius 90

  • New 4” C-CAM® bass driver - Radius features all new bass drivers with concave cone profiles, introduced by our top-of-the-range Platinum speakers and applied subsequently to Gold GX.  Extensive research and FEA modelling have allowed us to perfect the relationship between the new radiating diaphragm and its motor design, introducing larger motor sizes and voice coils for increased excursion, higher power capability and reduced distortion.
  • New C-CAM gold dome tweeter - optimised to deliver the finest and widest performance within the compact Radius cabinets. It benefits from a more efficient rear-venting design, releasing air trapped and compressed at the back of the tweeter dome, and guiding it around the drive assembly to a rear-loading chamber.
  • HiVe®II port design - Straight from Platinum’s design blueprint, the HiVe reflex port makes its Radius debut. It’s shaped to have the same effect on airflow as a gun-barrel on a bullet. Rifled grooves inside the port help to accelerate the flow and reduce turbulence, so air moves in and out of the port more efficiently, for a faster more dynamic bass response.
  • Single through-bolt driver fixing provides mechanical de-coupling and enhanced mid-band clarity and resolution. The through-bolts also act as rigid cross bracing to give a very solid non-resonant cabinet.
  • Single point ¼”x20TPI wall fixing. Use the optional Monitor Audio speaker mount or any standard wall bracket
  • Optional floor-stand with internal (pre-wired) cable management system.
