Hi everyone,

I wish to construct a cheap pair of studio monitors. As such, my design goals are neutral response, and tight transients, over a range of about 50 Hz to 20 Khz plus. I will be using a subwoofer, so they need not extend lower.

I have alread chosen some woofers, with economy in mind. Although relatively inexpensive, they look to be well suited as monitor midbass drivers. They are Max Pentavent 6520-8's. They are 6.5 inch midbass drivers, with heavy stamped steel frames, butyl surrounds, 1 inch voice coils, large spiders, and carbon infused poly-cone. I have yet to find a frequency response curve for them, but supposedly they are usable to 5 KHz.

Here is my question, then. In chosing a tweeter, should the impedance be matched to that of the woofer? Many tweeters seem to be 6 Ohms, where as my woofer is 8 Ohms. Can these be made to work together?

My midbass has a SPL rating of 90 dB 1w/1m, 8 Ohms, and high end extension to 5 KHz. I am planning on crossing over at a more pedestrian 2.5 KHz, or 3 K, to a textile dome tweeter of some kind.

Any suggestions? I have found a few tweeters with a SPL of 90 dB also, which is a match to my woofer, however they are 6 Ohm impedance units. If I correct them to 8 Ohms with a padding resistor, that will lower the SPL. I am at a loss as to how to match the impedances of a midbass and tweeter.
