Bose Professional DM6C Reviews

Big, heavy, and LOUD!

By William
Rated 5 out of 5
Date: 2026-04-12

Bought these to replace some Boston Acoustic 8" ceiling speakers that had failed after 15 years in use. My client has some hearing issues, and likes his music LOUD. These speakers fit the bill. They are pro level gear, heavy, with full back boxes. They are expensive compared to the low end of the market, but are really a completely different animal. And they rock. Even driving them at 100w, I couldn't bring them to full, it was just too loud. Exactly what my client wanted. Be aware of the size. They are wide and tall. I got lucky and they fit between the ceiling joists, with about an inch to spare, and one barely fit under a pipe in the attic. If you have a complicated ceiling, you definitely want to open a smaller hole, and have a backup speaker in mind that is shorter if needed. It's definitely worth it to look in the attic before committing to the big hole. Bottom line, they eat power for days, sound great, and my client loves that he can rock out.
