Why so many B & W Speakers on the used market?

I think there's 2 reasons for amount of used B&W's on the market:

1. They have been around for 60 years and have always had a pretty broad range of speaker choices, across many price points. They have also developed a wide range of retailers and distributors.

2. I also agree with some posts here that B&W's seem very forward and can be fatiguing, to my ears, especially at the lower end of their range.

When partnered with more laid back sounding electronics they can be a nice listen.

They sell a bunch of speakers. I think they also tend to have a "house" sound which over time and exposure to other speakers can become tiring. 

Brands marketed in big box brick and mortar outlets are ubiquitous on used sites. Search engines are paid in full. If you pay enough you get a nice familiar speaker. But you lose the hook of something people haven't seen, and the expertise of producers who do not participate in the search/review game. If you care.

Thanks for all of the responses. I thought maybe I hadn't heard about a decline in quality, as I wouldn't have expected. I agree with many of the replies as one brand with a huge amount out there will commonly have more available in the resale market. As for the forward/brightness issue, I actually have not auditioned the brand in many years, so it's good to know this characteristic. For the models I see often, being in the mid-fi price range of less than $2,500/pr., I would guess that most of these buyers have paired them with less than ideal amps, often being used with multichannel home theater receivers, thus compounding the brightness and forward soundstage presentation. It also reminds me of my college years, circa 1980, when I knew several guys that had JBL loudspeakers. Although they were popular and cost 2x-3x my Large Advents, their brightness made my ears bleed. But that was their trait and very few fed them anything other that the power from a Japanese receiver.

B&W sells A LOT of speakers here in the states. Maybe they offer a higher mark up to their venders, but they are everywhere! They are most always powered by Mac in said stores and if you don’t use an amplifier that quiets down those tweeters, you might have issues with brightness.

Just my 2c.
