DRIVE UNITS BY MANUFACTURER:
DC250-8
NEW PRODUCT - IN UK STOCK NOW.
The Dayton Audio DC250-8 is a 10" 8 ohm woofer designed as a general replacement for larger traditional 3 way loudspeakers that feature a pulp or paper cone woofer as were popular in countless vintage designs from the 1970s / 80s. This unit has a great bass response and is an excellent cost effective way of reviving retro loudspeakers.
The Dayton Classic Series all offer an excellent price / performance ratio and are available in 5¼", 6½", 8", 10", 12" and 15" chassis sizes.

Quick dispatch
I needed to renew the foam fabric around my JR149 loudspeakers. Age and UV light had caused them to start disintegrating - not helped when one of our cats decided to assist with her own paws!!
Googled and up came Willy's details. I confirmed that I needed two of the "large" sheets and paid by Paypal. Order promptly dispatched and JR149s cosmetically restored!
As always, items arrived nicely packed and promptly.
I purchased these as substitutes for another driver that was used in a transmission line design. The old drivers had way too high a Q and sounded a bit boomy.
I chose these mainly because the diameter was exactly the same as the original drivers, meaning no cabinet reworking :)
They behaved very well in the transmission line cabinet and don't exhibit any peaks or nulls in the response. Very easy to work with and the 2nd order crossover couldn't be much simpler, crossed at around 2.4K which was mainly determined by the DT105 tweeter I was using, the drivers blend really well together.
Overall these are a very good sounding driver with a natural and neutral sound.
For those interested, I have included pictures of the speaker, crossover and measurements.
Tip: Run these drivers in before measuring and designing the crossover!
Good service well packed
I've needed something like this for years, fantastic product and a lovely company to deal with. Won't be my last purchase from them
It was a nice experience to send the old filters to the UK (from the Netherlands) and get them surprisingly fast back (taking the overseas shipment into account). At first I did it wrong since I also replaced the drivers that could also be connected in a 4/6 Ohm (double coil). But after correcting and calibrating my receiver the speakers sounded great.
Thanks!
