Hey CT Sounds thanks for saving me a ton of money!

Hey CT Sounds thanks for saving me a ton of money for my new speakers. Bought a pair of Bio 6.5 ceilings 2 ways to replace Pxxks that dry rotted out. Funny thing is that they are nearly identical size wise so no cutting. Crossover is different but the drivers are really similar. Sound nice clear with good mids. Nice quality and I like how much the tweeter is aimable. Definitely keep CT Sounds in mind next time I need speakers. Way to go Coleman

Great value, cutout template leaves a little to desire.

Hard to beat the quality for the price. My only complaint would be that the templates that are included for the cut out are printed on paper instead of cardboard, and they aren’t perforated like many other in wall and in celing speakers I’ve installed in the past. A minor inconvenience that is easy to overlook given the price.
