A normal? loudspeaker !

Andy G · 5th July 2006, 09:36 AM

Here is progress pic of the KEF+ 4-way.
The bass unit is a KEF B139 in a TL (driver cost $0
Top unit contains 3 drivers and slopes back at approx 8 deg to try to vertically align the mid with the mid/tweet: mid will be sealed, other drivers don't have cabinet because they don't need it.
edges will be rounded slightly.
Vifa C13Wg, bought on sale for $20AUD each
KEF T15 38mm dome mid/tweeter $0
Foster ribbon tweeter $25AUD each

It's sort of "use what you have" speaker fun project.
x-o points are aimed at 250, 1500, 7500 in 4 way series x-o

All those weird compound angles in the top unit are proving quite fun ;-))

I'll let you know when/if I get them to a listenable stage !!!

Got a new (2nd hand) CD player cos the Tascam final seems like its giving up the ghost.
Its a Marantz CD-94... sweet sounding machine :-))

Great... be good to have a listen.

Tascam might just need a new laser or a clean.... maybe. The price of used CD players on eBay are going through the roof and glad I stocked up on some used players.

planet10 · 6th July 2006, 04:10 AM
