There was a review of the Radio Shack use of the tweeter
several years ago.

Stereophile Review of Radio Shack speaker

From the review:

Quote:

while a 6.2µF plastic-film series capacitor keeps LF from the tweeter.

Quote:

Description: Two-way, stand- or bookshelf-mounted, reflex-loaded box loudspeaker. Drive-units: 5" polypropylene-cone bass/midrange; 2" by 4" Linaeum dipole tweeter. Measured crossover frequency: 4–5kHz. Frequency range: 85Hz–20kHz (no limits given). Measured sensitivity: 81.5dB/2.83V/m (B-weighted). Nominal impedance: 8 ohms. Amplifier requirements: 100W recommended maximum.

Quote:

The Linaeum tweeter comes in sharply above 2kHz, but on-axis at least, its output is down in level and looks very ragged.

That might give you a starting point.

I am pretty certain I have radio shack brochure at home. I bought them while back. Give me some time, I will find it for you and scan it.
