Put them in a corner with spike feet and 10 pounds of sand on top. It will add bass but may not sound better?
Getting more bass from Altec Bolero 890c Speakers
I would like to increase the bass response (dig deeper) of my Altec Bolero 890c's speakers. They are rated at 50 watts, and according to the Back-to-Basics Audio by Julian Nathan - simply adding more dampening material would do the trick and would also increase the power handling of the speaker. Is this true? I also read in another thread here, about place a large baffle around loudspeaker, and that Altec did this on many theater models. Has anyone ever tried this with their Boleros with positive results?
