Help Speaker replacement advice needed
 

Hi,
I found some old Marantz boxes in the attic. LD20 if that means
anything to anybody anymore, probably not. 14" by 9" by 10"
outside, 2 way, vented. Foam turned to dust on bass units.

Since all I have is two probably usefull ready-made enclosures
my question is what speakers should I get to use there. Not
expensive and available in UK. I would appreciate your
recomendations.

The original tweeters might work but the quality? The mid/bass
opening is 168mm, centre to centre is 143mm. All openings can
be cut bigger, vent can be closed, etc.

Is there any info site where I can compare dimensions or find
calculations to arrive at proper crossover frequencies. Maybe
manufactors datasheet sites? My old ref books are gone and any
math background I had went with them.

It was long ago since I DIY-ed speakers and the old favorites
are irelevant today probably.

Thanks

Try phoning Wilmslow Audio.

They can possible recommend a drop-in replacement that will
work with the original crossover. **

If not, they could probably supply a matched set of woofer,
tweeter and Xover which will fit the cabinet.
All the designing you have to do is pick the right size reflex vent.

** It's a Marantz. It probably doesn't have a crossover :-)

I'd say that buying a complete set of replacements will cost more than
simply a new pair of speakers of equivalent or better quality. Unless you
really like experimenting.

You might find a kit of speakers and crossover etc of the right size where
you would normally build the cabinet is reasonable value, though.

Wimlslow Audio do such kits.

I would recommend getting a copy of 'Winspeakerz' (It's not expensive)
and using the library of drive units, (and your internal measurements of
the box of course) to see which current bass unit gives a good response.
