Airpressure behind speaker will decrease, will it not affect speaker movement?

So you will not add an unwanted air vent in your cabinet but only a cooling vent. Amplifiers are never build directly in a speaker cabinet. Edit : unless they are very cheap.... It's not about what you got to use .... but how you use what you got... Would you like to comment this tip? Log in Become a member
