No bass on B&W 800D2


Hi,

I’ve been a B&W fan Since the late 90s and have owned many different speakers over the years. I’ve owned a pair of 802Ds (first gen) For a long time and those had always been my dream speaker. 

I recently had the opportunity to upgrade to a pair of 800D2. I had never heard the 800 or the second generation diamonds before, but was tempted by the idea of owning the flagships. I don’t like the looks and sound of the newer generation 800 so in my mind, I was upgrading to the top of the line speaker of the last generation that I like.

I’ve had these speakers for three months now, and I’ve played around with positioning and levels of my subwoofers. when I first set them up I immediately noticed a lack of bass compared to the 802’s. I listen in the near field and have the 800 approximately in the same position as the 802, although with slightly more toe in and a little further away from the wall as they seem more sensitive to room placement than the 802s did. Even pushed up to the wall there is not more bass, just boom. 
 

I’m powering them with a Classé sigma amp 2, which doubles to 400W a channel on 4 ohms. Before you say it’s the amp, the 802s sounded exactly the same on my Denon 4520 as they did on the Classé amp after I upgraded to that - so I don’t really subscribe to the “more power” idea and believe an amp won’t change the sound dramatically as long as it’s decent quality and has enough power. I mostly listen at lower levels anyhow. 
 

Has anybody had the same issue with the 800D2 lacking so much bass compared to the 802D? The midrange sounds about the same and the highs are way more tame, which I like, but this lack of low end authority is making me seriously consider selling these again which makes me sad - since they are absolutely gorgeous in the looks department. 
 

thanks for your thoughts in advance - would appreciate hearing from actual owners of these.

In addition to polarity, worth checking the drivers are actually working.  The inductor wires are especially susceptible to having nearly invisible cracks happen at the circuit board.  

Try running the speakers with only the bass terminals connected to the amp, no jumpers or direct connection to the mid/tweeter. Play music or test signals to evaluate whether the bass drivers have the same output. Try different speaker positions. Sometimes only a few fractions of an inch make a big difference.

Also might inspect the bass port to see if a prior owner stuffed a sock in there.

Stereophile's measurements show that the 802Ds have a few more DBs in the bass range vs the 800D2s.
