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 ayosha |

Try phoning Wilmslow Audio. http://www.wilmslow-audio.co.uk/ 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 :-) -- Roger. |

I would appreciate your recomendations. 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 can see your point, but I still think you're full of ****. Dave Plowman London SW 12 RIP Acorn |

Thanks ayosha 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. -- Chris Morriss |
