This 1964-1967 Cutlass dual voice coil dash speaker is a single 4x10 speaker that will play in stereo and fit in your original dash location. This 1964-1967 Cutlass dual speaker has two tweeters on it, one for the left channel and one for the right. The 4"�x10"� speaker cone provides better midrange sound than the dual dash mount speakers as it has more surface area in order to produce those lower notes. With 140 watts of peak power, 70 watts per channel, this speaker will give you high quality sound while maintaining a stock look in the dash of your 1964-1967 Cutlass. This is the speaker we recommend for your 1964-1967 Cutlass and yes, even over the more expensive Kenwood option.
