Here is a pair of DB Plus 880 Speakers in good condition. They are made in Canada, by Sound Dynamics I believe. They use a 10" woofer that is very similar to the sound dynamics 10" woofer, like in Sound Dynamics 10s. The drivers were made by API, who made drivers for many Canadian speakers. The tweeters very closely resemble the Infinity Polycell tweeter, I believe they were made by the same company as well. These are a very good sounding speaker. The name DB may not be well known but they are the same quality as many other Canadian made speakers, like Sound Dynamics and Infinity. The woofers have just been refoamed. May be auditioned. Gear serviced RIGHT. Care taken and no half fixes. See my other ads for vintage audio/guitar equipment.
