Gold 50 6G features a 1" MPD III Tweeter and 1 x 6" HDT C-CAM Woofer with a Crossover frequency at 2.5 kHz. On the other hand, the 606 S2 AE features a 1" Aluminum Decoupled Double Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
Gold 50 6G has a frequency range of 55 Hz - 60 kHz whereas 606 S2 AE has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 606 S2 AE can go slightly deeper then the Gold 50 6G's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Gold 50 6G is a 4 ohms speaker compared to the 606 S2 AE which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Gold 50 6G can provide this impedance level.
These two speakers also have different sensitivity levels. Gold 50 6G sensitivity is rated at 85 dB and the 606 S2 AE's is rated at 88 dB. This 3 dB difference makes the B&W 606 S2 a more sensitive speaker compared to Monitor Audio Gold 50 6G, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Gold 50 6G can handle a max power of 150 watts RMS, whereas 606 S2 AE has a max power handling value of 120 watts RMS, 30 watts less than the Gold 50 6G.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both Gold 50 6G and 606 S2 AE features dual binding post speaker terminals for bi-amping or bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Monitor Audio Gold 50 6G's and B&W 606 S2's external dimensions. Monitor Audio Gold 50 6G has external dimensions of 321.0 x 186.0 x 304.0mm (7-5/16 x 12-5/8 x 11-15/16) whereas B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm (13-5/8 x 7-1/2 x 12-13/16inch).
B&W 606 S2 is clearly the larger of the two speakers. Its body is 5mm wider, 26mm taller and 22mm deeper than Monitor Audio Gold 50 6G.
Below you can see the front view size comparison of Monitor Audio Gold 50 6G and B&W 606 S2 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Monitor Audio Gold 50 6G is approximately 565.4cm2 / 87.6inch2 and base area of the B&W 606 S2 is approximately 622.7cm2 / 96.5inch2. The Gold 50 6G requires 9% less surface area than the 606 S2 AE which gives it a small advantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Monitor Audio Gold 50 6G weighs 8.52kg / 18.7lbs and the B&W 606 S2 weighs 6.90kg / 15.2lbs. This makes the Gold 50 6G 23% heavier than the 606 S2 AE.
Here is a comparison of how Gold 50 6G and 606 S2 AE's weights compare with the average, max and min weights in Passive Bookshelf class.

These sit in different price classes - Monitor Audio Gold 50 6G costs roughly 2.5x what B&W 606 S2 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | B&W 606 S2 digs deeper - 52Hz against 55Hz. A subwoofer would even that out. |
| Amplifier needs | B | B&W 606 S2 is more sensitive (88dB vs 85dB), so it goes louder on the same amplifier. |
| Amplifier match | B | B&W 606 S2 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | Monitor Audio Gold 50 6G takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Monitor Audio Gold 50 6G: bi-amping; B&W 606 S2: bi-amping. |
| Price | B | B&W 606 S2 is cheaper - $999 against $2,499, about 60% less; arguably a different class. |
A Monitor Audio Gold 50 6G B B&W 606 S2
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
B&W 606 S2 is the easier recommendation: it leads on most of the measured areas and costs less. Take Monitor Audio Gold 50 6G if its size, looks or fit in your room suit you better. If your amplifier is modest, vintage or valve-based, B&W 606 S2 is the safer partner - the other will want more current or more watts to sound its best. Think about the whole system, not just the speakers: the roughly $1,500 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
