tweet to match 4ohm vifa pl's

raginbullwinkle · 12th December 2006, 01:59 AM

I was just able to snag some vifa pl18wo09-04's for a good price, so i am considering using them in an inexpensive 2 way setup. This project is just in its formative stage, so im trying to get some suggestions for a good tweeter to match before starting anything.

1.Would i be correct in looking for a 4 ohm tweeter to match?(to be used on a reciever capable of 4 or 8 ohm operation)

2.Should i be looking for dome tweeter, perhaps something that can
be crossed over low?

3.Any budget(sub $25 per speaker, less if possible) tweeter suggestions?

No. the higher the tweeter impedance used the better.

thank you for the reply and link sreten. So it is acceptable to use an 8 ohm tweeter with a 4 ohm woofer? I was under the impression, and perhaps it is an erroneous one, that the amplifier sees the eight ohm load on higher frequencies and the four ohm load on lower frequencies. Would that combination be acceptable for the amp? Sorry about the stupid questions here, im an audio neophyte kinda learning on the fly

This is true.

Yes.

Note that you need a properly designed crossover,

you should cross vifa pl as low as possible
(the driver is very good in bass, and not so good in mids)
so i suggest seas H1212
