Sorry for the pre-mature panic- Did some research and found that they are the right ones...
The Boston S85 6"x8" speaker features a 3/4" tweeter with a built-in cooling system for long term reliability and excellent power handling. A contoured tweeter plane guides high-frequency output to create a larger listening "sweet spot," while Boston's Amplitude Modification Device (AMD) reduces harshness in the upper mids for clear, detailed sound.

The sturdy woofer cone teams up with a durable butyl rubber surround to produce tight, clean bass with minimal distortion. And you'll hear a smooth blend between the woofer and tweeter, thanks to the built-in crossover. Grilles are not included. (Factory grilles are appropriate for most installations.)
Note: Although the Boston Acoustics owner's manual for this speaker says that it's a 5"x7" speaker, our research has determined that it only fits into 6"x8" openings.
