series connected speakers

[dobias]

I'm wiring up a full range Wharfedale assisted by two tweeters & two woofers working with 6 dB slopes. In order to keep the total impedence within reason, I'm thinking to wire the two 10 ohm tweeters in series with a 2 mF cap. The two 15 ohm woofers would be connected in series with an 8 ohm inductance. The woofers, tweeters & 15 ohm full range would all be in parallel for 7.14 ohms.
Is there any inherent problem in wiring speakers in series?
I'm not looking for a 3-way crossover.
Thanks for any help.

I can't answer your question, but it sounds like an odd combination of drivers.

May I inquire about the purpose of it all?

What's an 8ohm inductance mean in this context? Seems like pretty high value.

Kal,
That's what I get for not proof reading... that should read "8 mH inductance". The crossover (as I read it) would be 600 Hz.

whoaru99,
I'm boosting the top & bottom end of the full range 12" Wharfedales on OBs. I hoped to go the additional step & use two tweeters & two woofers with each full range speakers. I would have preferred to wire the woofers in parallel to get an increase in output but the total impedance would have been too low. Now I'm trying to determine the best combination or whether to just use a single tweeter & woofer with each fullrange. I'm told that I may have problems with "comb filtering" by using a pair of tweeters side-by-side facing up. Unfortunately, I don't comprehend the ramifications of comb filtering.

When there are 2 high frequency point source drivers playing the same passband, the sound will cancel at some frequencies and combine at other frequencies.

If one looks at a frequency response plot it looks like the profile of comb. The teeth are where the frequencies combine, the voids between the teeth are where the frequencies cancel.

The effect of comb filtering is terrible sound

BTW it's a 8 mH inductor, not 8 mH inductance
