About the Bowers & Wilkins 603

Eric A.

Excellent full-range sound

I love floor-standing "tower" speakers because the larger cabinet can hold more specialized drivers to create an immersive, accurate soundstage. The Bowers & Wilkins 603 draws on the famed speaker manufacturer's long history of technical innovation to do just that.

The Bowers & Wilkins 1" Decoupled Double Dome tweeter

The 1-inch Decoupled Double Dome tweeter in the Bowers & Wilkins 603 makes movie and TV dialogue come through crisp and clear.

You can use a pair of 603s to star in a classic stereo music listening setup, or use them as a front pair in a Bowers & Wilkins surround sound system.

Proprietary drivers

A closer look at Bowers & Wilkins' driver technology will give you some idea of why this speaker sounds so good.

The 1" Decoupled Double Dome tweeter features a thin, light aluminum dome, surrounded by a second, thicker ring that reduces distortion. The assembly is decoupled from the mount to isolate it from cabinet vibrations that can color sound.

The 6" Continuum™ cone FST™ midrange borrows technology from the company's high-end 800 Series. The cone's composite construction delivers precise vocals and instruments and smooths transitions.

Flowport™ for better bass

The speaker's dual 6-1/2" woofer bass cones provide deep, rich bass, which remains smooth thanks to Flowport technology. The 603's bass reflex enclosure features a rear-firing, dimpled and flared port that provides natural bass response without the turbulent "chuffing" that standard ports can create. The speaker includes a two-piece foam plug that can be inserted if you want to adjust bass response to your liking.

My hands-on experience with Bowers & Wilkins 603 speakers

I had a chance to audition a pair of these amazing floor-standers at home, and they're the best speakers I've had in my living room to date. 

I have a playlist of about 25 songs that I use to test every pair of speakers, so I have a baseline for a true comparison. These towers delivered power and nuance that made a difference on each track. I reveled in the clean, clear vocals on Cassandra Wilson's version of "Don't Explain" — I could hear the complex tonality of her voice, and feel the ache in the way she delivered the lyrics. That was a testament to the decoupled tweeter and the dedicated midrange, as well as the influence of clever cabinet design and well-engineered crossovers.

To test the power, I also played several songs with challenging low-end passages and found the bass to be punchy, musical, and never distorted. Again I credit cabinet design and driver materials, plus the ingenious Flowport technology. There were some bass passages that I could feel as much as I could hear them, and I must admit I giggled with glee when they hit while I was listening to these speakers. The first one I always turn to is James Blake's "Limit to Your Love," which drops into atom-rattling territory about one minute in. PJ Harvey's "Joy" is another that really benefits from a well-tuned woofer.

The upshot is that the 603s bring out the sublime quality in music. They create a blissful sonic bubble you can sit inside for a while — a place where you can forget about everything else and simply live in an exquisite moment. That's what these speakers do best.

Build a complete Bowers & Wilkins system

The 603 is voice-matched to other speakers in the 600 Series, so you can build a seamless surround sound system.

Product Research


1" Decoupled Double Dome Aluminum Tweeter: The Bowers & Wilkins 603 floorstanding loudspeaker adopts a refined and upgraded version of the proven Decoupled Double Dome Aluminum tweeter (1"), offering 38kHz breakup performance. The Decoupled Double Dome tweeter uses a thin and light aluminum dome, surrounded by a thicker ring, to prevent audible distortion. Decoupling also helps prevent cabinet vibrations reaching the tweeter. Synthetic gel cushions the decoupled tweeter, with the assembly isolated from the mounting hardware. The result is a more natural, spacious, and pure sound.

6" Continuum Cone Midrange Driver: The 603 floorstanding loudspeaker features a single 6" Continuum cone FST (Fixed Suspension Transducer) midrange driver, borrowed from B&W's 800 Series Diamond. Thanks to its composite construction, the Continuum cone provides a smooth and accurate sound by avoiding the abrupt transitions in behavior that can impair the performance of a conventional drive unit and cause distortion. As a result, voice and instruments are delivered with purity and precision.

Dual 6.5" Paper Cone Bass Woofers: The Bowers & Wilkins 603 houses dual 6.5" paper cone woofers with rubber surrounds. These 6.5" paper cone woofers deliver deep, accurate, natural sounding bass.

Flowport Technology: The B&W 603 floorstanding speaker utilizes Flowport Technology to create smooth, deep, and efficient bass response. Its bass reflex enclosure features a rear-firing, dimpled flared port that provides natural bass response without turbulent noise or distortion. If you want to reduce the volume of bass without moving the speaker further from the wall, fit the included foam plug into the rear-firing port for lesser bass response.

Note: You can adjust the floorstanding speaker's low-frequency performance using the supplied foam plug. The foam plug is two-pieces, allowing for a degree of fine-tuning using either the outer, larger-diameter piece in isolation or the two parts together. Using solely the outer, larger-diameter foam piece will deliver less bass attenuation than the complete foam plug assembly.

Acoustically Transparent Magnetic Grille: The Bowers & Wilkins 603 comes with an acoustically transparent magnetic grille that's easy to install, looks great, and doesn't get in the way of the sound.

Dual Binding Post Terminals: The floorstanding speaker has two sets of binding posts connected by jumper straps. The binding post terminals will accept bare wire, pin connectors, spade connectors, or banana plugs (single only). There are plastic inserts that will need to be removed from the binding post terminals in order to use banana plugs. Using the dual binding posts terminals, you can choose to bi-amp or bi-wire the speaker (when facing the back of the cabinet - the left set of binding posts are for the high frequency drivers; the right set of binding posts are for the low frequency drivers).

  • Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier.
  • Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.

Note: Make sure the jumper straps between the dual binding post terminals are removed when making a bi-amp or bi-wire type of connection.

Rubber or Spike Feet: The Bowers & Wilkins 603 floorstanding loudspeaker comes with a plinth (base), rubber feet, and spikes. The plinth (base) secures to the bottom of the speaker cabinet using the supplied hardware. The rubber or spike feet screw into the bottom of the plinth (base). Use the rubber feet for hardwood, laminate, tile, and vinyl flooring. Use the spike feet for carpet flooring.

  • Dimensions with Rubber Feet: 12.625" (w) x 40.75" (h) x 14.625" (d)
  • Dimensions with Spike Feet: 12.625" (w) x 41.5" (h) x 14.625" (d)

Note: The 603 floorstanding loudspeaker should always be used with the plinth (base) and feet installed for optimum performance and proper stability.

Placement Options: Moving the floorstanding speaker further from the walls will generally reduce the volume of bass. Space behind the speakers will also help to create an aural impression of depth. Conversely, moving the speakers closer to the walls will increase the volume of bass.

  • Stereo Setup: The floorstanding loudspeakers should be positioned between 4.9375' and 9.875' apart at two corners of an equilateral triangle completed by the listening area at the third corner. The speakers should be approximately 1.625' away from the back wall, and at least 1.625' away from any side walls.
  • Home Theater: If the floorstanding speakers are to be used for the front channels in a home theater system, position the speakers within approximately 1.625' of the sides of the TV screen to keep the sound image in scale with the visual image. The speakers should ideally be at least 1.625' away from any side walls.

Bowers & Wilkins 600 Series: The Bowers & Wilkins 600 Series consists of a floorstanding loudspeaker (603), two bookshelf loudspeakers (606 / 607), a center-channel speaker (HTM6), and three powered subwoofers (ASW608 / ASW610 / ASW610XP). The 600 Series delivers Bowers & Wilkins' storied sound in simple 2ch stereo applications or more complex home theater setups.

Do you have to use the Plinth?

Yes I did
giovanni lorenz  Dec 18, 2020
You don't have to use it. The hardware kit provided gives you options for both carpeted and non-carpeted floors.
eric  Dec 10, 2020
The manual says you pretty much do need to use the plinth. You could try it without, but I would question the stability.
susan  Dec 06, 2020
Yes I certainly would. I have 2 pairs of B&W's and the plinth is on both sets one on a hard floor and the other on a carpeted floor. Just use the included spikes or rubber feet depending on the surface you are standing them on.
paul  Dec 05, 2020
Yes, it is a must.
vipul  Dec 05, 2020
Hi Steve! I have wood floors and used the Plinths with rubber feet. They do provide a lot of stability and the speakers look complete with a clean finish. If you are planning on setting your B&W's on wood floors try to see how they look without the Plinth! At the end of the day the Plinths are given for a reason! I hope this helps.
shaun  Dec 04, 2020
You CAN attach the feet directly to the speaker, but it's a lot less stable without the plinth. It would be kinda sketchy on carpet, but as long as you don't have small kids or dogs, it would probably be ok to attach the rubber feet directly to the speaker and put it on a wood or tile floor. I had attached the rubber feet directly to the speaker on my tile floor, but I was nervous about it tipping over, so I ended up attaching the plinth.
jeremy  Dec 04, 2020
No, I didn't need them and they are very stable . The speakers are very heavy. Hope that helps.
brad  Dec 04, 2020
I believe you do and should. The plinth adds stability and includes mounts/anchors for either rubber feet for hard surfaces or spike feet for carpeted floors. I am using the rubber feet over a wood floor. I also think it adds a good look. John
john  Dec 04, 2020
Yes, you do. At least I did. Wish I could share a pcture.
ted-maier  Dec 04, 2020
No! I would argue that in most applications save for maybe think rugs not and same for effect on sound
nnamdi  Dec 04, 2020
Yes we use
chau  Dec 04, 2020
I use the plinth because they make the speakers look better to me.
robert  Dec 04, 2020
What is the total shipping weight of one pair of B&w 603 speakers?
munim  May 30, 2020
2 answers
Not sure of the actual shipping weight but each speaker is really heavy. I'm sure you can get the weight of each speaker and then I would add another 10-15 lbs. Hope that helps.
brad  Jun 09, 2020
The total weight is about 115 pounds for the set.
