If I wanted to buy a NEW 3.2 ohm speaker to use with a Hammarlund radio

would two 8 ohm speaker in parallel work?

I suspect that a 4-ohm speaker, or two 8-ohm speakers in parallel, will
sound just fine.

Is anyone using a DSP unit with their boatanchor which they would
recommend? Most [All ?] DSP units distort the audio so there is probably
always some distortion, but some DSP units would be better than others.
I am thinking in term of AM signals broadcast band reception.

I have followed the price of the Hammarlund speakers on ebay and they
are a bit expensive. I assume they would be best, but a bit rich for me..

I don't know what you want the DSP unit to do, or what you're calling
"distortion", but just about any post-audio filtering unit is going to
work by "distorting" the signal -- the question isn't "does it distort?",
but "does it improve other things enough to make the distortion
worthwhile?".

Beyond that -- I dunno, I really got on to answer your speaker question.

The noise I [most] want to eliminate is the HISS when you receive a
weaker signal.
The hetrodyne can also be a problem, but the slot can do some good,.
I got the Hammarlund because I wanted the full quality sound on AM.
I will have to except some distortion when I use a DSP unit.
The CLRSpkr DSP is a reasonable unit to use I think.
I would like to eliminate or decrease the fading effect by a better
AVC.
Well I cant have everything with a Hammarlund.Thanks to ALL for their
responses.
PS:: Is there a Service Bulletin to the HQ-145X ?
