[Dean Halleck]

- Hi CJ ... after telejunkys joke ---- --- I read your name and I'm afraid all kinds of things went thru my mind .. , I'm going to blame it on him - lol, lol ...... made me wonder if Payne last your last name or just avatar name...

- Thank you for posting your models, and for the additional info on the different variants!!

- Hi telejunky,

- Bozedale, Wharfezak -- LOL , LOL - !!!!!


- Can you post a diagram of what your crossover looks like??

- klipschorn is also helping me with some changes to my W70's as well , he has test equipment and working knowledge of crossover design.... ( unlike myself ) -

- I'm thinking, since yours is different from mine I could build your Xover and his as external Xovers and switch between them .... I would like to compare the two results and post them here maybe others can benefit from it...

----

- Where did you guys find your Model numbers at? , I don't see a model number on the inside, or outside of the box??

-----

mine just has a plate on the back above my two controls that says -

THE RADIO PEOPLE Ltd.
25 CHATHAM ROAD ,
KOWLOON HONG KONG
SERIAL No. 38386

-- My W70 is - Acoustic Suspension , has three drivers , the Midrange is a square red Alnico Magnet, the Woofer and Tweeter are Ceramic // the Speaker has -- one Inductor / coil , one 4uF and one 18uF Capacitor , it has a Treble and a Midrange Potentiometer ... the Midrange doesn't appear to be passive , the only cover is over the Ceramic magnet Tweeter...


Thanks,
Best regards, Dean

PS. I was going to include in my description - and looks better than all other W70 models.... but well maybe not...

- I am interested in trying your crossover and the cover on the midrange driver... and compare it to mine.

Thank You!

however the 8" is definitely not a passive radiator

I think there may be some confusion here. What Wharfedale are saying is, that the 8" functions as a passive radiator for the bass, and an active driver for the midrange. Any driver that has an open back and shares a sealed enclosure with a woofer will move because of the pressure inside the cabinet. This is why manufacturers put their midrange drivers in cups, or use a driver with a closed back. Since Wharfedale used a relatively large 8" driver for the midrange, it sounds like they tried to use this cone area to their advantage by having it function as a passive radiator also.

Hi leesonic, Did you ever get your drivers back, or get a pair of W70's up and running?

Nah... drivers got sold on, cabinets got trashed. Put it down to another project that didn't work out right. In hindsight, I wished I'd persevered with them, but I needed to thin down the herd prior to moving.
