I recently connected an 8" speaker with a 2" tweeter in
a baffle to my receiver. The audio is much improved

for this?



My guess is it could be due to a combination of woofer (8")
resonance and under damping (high amplifier dc resistance).
Making it free standing, varying the height off the floor, not
placing in a corner or on a shelf or desk and other physical
orientations can change the room-speaker resonance dramatically
sometimes.

Stuffing fiber glass etc into the enclosure will dampen it as will
closing any enclosure ports (it could make it worse too).
Lifting the speaker off its baffle a bit (spacers) or completely
out will change the resonance a lot

The least efficient way is to try various inductors in parallel
with the 8" Try a 6, 12V secondary with and without a core or a
cheap woofer crossover coil.

Then there's adding negative feedback etc.

All in all it's proably easiest to just get another smaller
speaker.

Radio Man, try a 10uf non-polarized cap on your tweeter, to smooth out
frequency response. If you have a woofer coil, bypass it as well. Didn't see
what type of receiver you're using, but most modern solid-state units
emphasize bass-n-midrange as a means of fighting static crashes-n-other
hi-frequency rfi content. Utilizing outboard amplification, via tape output,
will produce acceptable hi-fi quality sonics. Got a cap modded ICOM R-75 which
now replicates that 70's-era Pioneer midrange-centric fidelity, when driven
through direct-coupled Marantz MR-235 amplification. Through the stock speaker,
though, audio is still pedestrian at best.

you need the nonpolarized capacitors that are used for speaker crossover
parts. radio shack used to have them fairly cheap. buy several of the
largest value ones. one of the caps will go in series with the speaker.
now it will sound thin and tinny. (like a midrange driver....... thats
what the caps are for, to limit the bass to a midrange or tweeter
driver) now drop another cap in parallel with the first one. there will
be more bass available due to the change in capacitance. keep increasing
the cap value this way until there is enough bass to sound like you
want.
