Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.

B&W 606 S2 needs about 101% more floor or shelf area. B&W 606 S2 is 161mm deeper, so it stands that much further out from the wall. B&W 606 S2 is 40mm taller.

Cabinet type and Materials

Spendor Classic 4/5 has a Acoustic Suspension type cabinet. Acoustic Suspension loudspeakers aka Sealed speakers have no openings such as ports or slots.. They can be designed smaller, the bass is more accurate and tighter compared to ported designs but doesn't go as low on the lower end in general.

Wall Mounting

Classic 4/5 doesn't sport any built-in mounting bracket, so you need an external structure to mount it on walls.

Does the Spendor Classic 4/5 come with a Grille?

Classic 4/5 comes with grilles. The purpose of the grille is to protect the delicate driver elements from external impacts while still allowing the sound to pass as clearly as possible.

Recommended Accessories

Here is a list of accessories that we think you may need for the Spendor Classic 4/5.

  • Speaker Cable and Connectors
    • Speaker Cables with Banana Plugs: If you know the lenght of the cable you need, this is the easier option to connect your speakers with your amp.
    • Speaker Cables without Connectors: If you are not sure about the lenght or need longer than standard cables with plugs, choose this option.
    • Banana Connectors and Plugs: If you chose the cables without connectors option or already have some cable around, pick the banana plugs separately.
  • Vibration Isolators: IsoAcoustics isolators are our favorite isolators but you may find more affordable options too.
  • Acoustic Panels and Treatments: Your room is as important as your stereo equipment so acoustic treatments goes a long way in improving the overall performance.
  • Speaker Stands: Stands bring your bookshelf speakers to ideal height (rule of thumb is to have the tweeter level with your ear in your listening position), helps stability and acoustical isolation.
