Help on low frequency cut out?

Does anyone here know of any cheap and simple way, without purchasing
two entire crossovers, to cut out the low frequencies to my two book
shelf speakers? The other speakers I have in my system can handle all
the power I put to them, but if I get the volume too high on anything
with very low frequencies the two little speakers start to distort.
I'd rather just turn them into mid and high range speakers and cut out
the low end. I'm not too much of an electronic whiz, so what I'm
looking for is something I can buy ready to use, cheap. Any ideas?

Thanks,

David

Try the RatShack.....
They used to sell some inexpensive crossovers, no box, just the boards.
I have them in a set-up I use. Can be mounted in the speaker box itself.

You can't 'idiot proof' anything....every time you try, they just make
better idiots.

I used some of theirs on some speakers I built years ago, but they
don't sell them anymore. The thing is, I don't want to send the low
frequency anywhere (to any speaker), I just want to block it.

place a capacitor in series with the speaker. id guess about 10 uF
non-polerized 35 working volts or higher.

as you have not specified a frequency cutoff, speaker impedance, we kind of
have to guess.

for more high and less lows make the cap smaller (less uF)

the cap goes directly to the speaker. if its a self powered speaker, its a
different matter.

Thanks for your answer. The speakers are 8 ohms, and I'm thinking I
want to cut out everything below about 300 Hz. According to a chart I
found, that looks like about 70 uF. All of which I'd have never known
if you and others hadn't helped me out by responding. Thank you.

I've seen people selling crossover networks designed to go into speakers on
eBay in a sub-category of Home Audio. One or two of these [with the right
properties, of course] would do what you want.
