Wanted: Dalesford 5" drivers

[phydeau]

First post, so I hope I'm in the right place.

Where can I find a Dalesford 5 inch bass driver for a Keesonic Kub restoration?

Any help and pointers much appreciated,

Thanks

I thought Dalesford rather specialised in bextrene and polypropylene bass units. Perhaps they are Elac or Audax? Any serial numbers?

This is 5" paper bass reflex and a cone tweeter. Who knows, except you, what the crossover is?

I wouldn't throw a lot of money at it. Any old 5" paper bass that will fit, and fiddle around with some tweeter resistors for level.

I'm not putting it down though. This sort of thing can sound very good.

I didn't know Dalesford did paper cones. I'd had both D30/110s and D100/200s - they were bextrene. They went in the bin a couple of years ago...

The frame on the Kub's bass driver looks similar to the smaller SEAS 11F-GX used in the Kolt.

Thanks for the replies.

here is a pic of it: -

Dalesford bass driver

One of the original designs, the Keesonic Kub was launched in the early 1980s.

The Kub was a compact, two-way, bass reflex loudspeaker using a 5.25-inch diameter paper cone woofer (with flexible rubber surround) and a 3" paper cone tweeter.

Supposed to be very good speakers, so I've heard...

These are so long out of production that the only way to get a woofer would be to salvage it from another Keesonic Kub.

Many thanks for the reply. Good suggestion to salvage from another keesonic KUB. New thread has been posted immediately.

I've had the same problem with a pair of Kubs that I sold and Parcelforce dropped and killed the bass drivers.
Just installed a pair of L022C drivers purchased from EBay and in process of running them in.
Using just a single voice coil winding for 8 ohm and they appear to be a reasonable quality driver for the (little) money they cost.
Give me a day or two and I'll get back to say how they sound when they have a few hours on them.

I would always want to see the crossover schematic when changing drivers. For all that, most 5" paper mid/basses are much the same.

You will usually have to adjust the tweeter level at least. The ear is fussy on bass balance and tweeter level.

Not hard. Wirewound resistors are cheap enough.

Those L022C drivers are a good replacement believe it or not!
They do seem to require a good long time to settle down and run in but what started out as harsh and forward is now a nicely balanced and punchy sounding bass with a clear midrange. Still somewhat chesty sounding but improving by the day and a week on with few hours in total a nice surprise!
May need a change of tweeter level but at the moment they seem fine.

 

[GJF]

More hours on the clock and getting better sounding for it!
A little bright and toward but hell, wasn't the Kub ever that way?

 

[system7]

It's not going to get better with time. If it's overly bright on the new woofer, you must fix that.

Thing is the new woofer may not be as loud, or may rolloff the mids less, so it spoils the balance.

You really need to draw up the crossover layout to figure out what to do or change. It shouldn't be hard. Probably just change a resistor value. 10W wirewounds are 78p at Maplin.

I have two I'd part with but the surrounds need some work.
