Has anyone heard of or poccess a Wharfdale E70 with one 10 inch woofer, two midranges, and a horn tweeter that was made back in the 80's?

If by lucky chance someone processes or heard of this loudspeaker- was it a high end good sounding loudspeakers back in the 80's?

I remember them. There were, from memory, three models in the range along with the model you mention. These were "High Effeciency" (over 90dB) designs made by Wharfdale in the mid 70's, though unfortunately they were the right model (for now; ie. se tube amps) at the wrong time (yesterday; all solid state)and did not quite catch on. Again from memory if I recall correctly Wharfdale did not skimp on materials, the main drivers had quality die cast alloy baskets and they were mid to hi end models. If they are in working order cherish them as they are eminently suited to tube gear.
Hope this helps.

So someone remembers...i used to have a working pair but sadly the bass driver in one gave way after 25 years of working. I drive the speakers in too high SPLs with the frigid bass turned to +3Db.
So, it was a high end loudspeaker meant for tube amps... I just wanted to see is my second hand wharfdales were high end..guess you provided the answer.

Yes, unfortunately to maintain efficiency they did not have very deep bass despite the relatively large enclosures and 10" woofers, and although they had good power handling, once people started turning up the bass control on their transistor amps, the drivers life expectancy was quickly shortened. I don't think recone kits are available any longer, but there are various after market voice coils available, so a reasonably competent repairer could fix it but it would be up to you to determine wether at the end of the day it is worth it to you, as it is likely to be expensive.

I had a pair many moons ago, seem to be very rare these days and go for very high prices.

Still have been my favorite speaker to date, never been able to match them for sound quality.

But then i'm using a pair of Goodmans "Magnum K2's" for 2ch music these days, Very nice reference speaker from 1972.

(After reading about Billy Woodman who owns/designs for the ATC speaker co., Billy cut his teeth in designing loudspeakers for Goodmans back in the late 1960's and aparantly he designed the K2's as well)

I remember them well, a friend a college had a pair.

Edit : actually he had E50's not E70's
to which the following comments apply.

I'm not so sure about the die cast frames, as I recall they
had die cast trim rings on all drivers, the port and the
tweeter level control, the actually technology IMO being
rather mundane.

The tweeter is very similar to this :
http://www.partsexpress.com/pe/showd...number=270-055

IMO in standard form I'd put them at Mid-Fi.

The crossovers are distinctly improvable, with better quality
capacitors and inductors, and replacing some small cored
inductors with air cored types, there is a very poor looking
small inductor/ resistor combination in series with the bass
units.
I know this because it expired in one of my friends speakers,
and I replaced it with a high DCR air cored type, which from
what I recall improved clarity.

IMO damping of the driver frames, some bracing of the cabinet,
rebiulding of the crossover, detuning the port somewhat etc.
would lift performance considerably.

Hi Guys,

Yes, I've had two pairs of E70's and a pair of the even larger E90's (2x10" bass drivers per side). They were quite awesome speakers in their day, but not what I would consider hi-end these days. I still have a pair of E70's tucked away in my shed unused.

The build quality was excellent, they looked fabulous with the fishnet grills and bold aluminium surrounds on the drivers. The E90 had a superbly designed 12 elelment Butterworth crossover with attenuators for mid and treble. The E Series by Wharfedale were their best modern speakers by far (their prior vintage series of the 1950/60's are also excellent). The E Series were closely followed by TSR 108/110/112 Series with time aligned, modular, funky looking, slanted enclosures. I had a pair of the TSR110 which were very smooth sounding with nice acoustic suspension/sealed boxes for low bass.

The E70/E90 were an efficient 95dB 8ohm load and were easliy driven by valve amps and any 25watt solid state amp, such as the NAD3020 at the time. I drove them on nice big 100w Luxman amps and the speakers had a nice 'alive' sound; punchy bass down to about 35Hz; were very robust and could go very loud! The horn tweeter and twin midranges are a bit forward and coarse sounding at loud levels, but it's difficult to fault the overall sound because it has that highly enjoyable 'boogie factor'.

I owned the big E90 for ten years purchased from new and I used it to pump out a lot of reggae (UB40 & Bob Marley) and late 1980's pop music (Dire Straits/Fleetwood Mac/Blondie) through them without any trouble at all. In their later years the glue on the spiders of the drivers came away and you could hear a rattling sound at high volume. But this was an easy fix, just apply a bit of contact cement to re-attach the spiders to the magnet and off you go again for another ten years. My E90 was eventually sold to an enthusiast/collector in 1995, and he still uses them to this day (and loves them). They are just about to complete their second DECADE of life!! Now that's saying something for product quality...


Regards,

Steve M.

Hi wharf. IMHO, the earlier Wharfedales are better than the multi-way. In your search don't overlook the Super 10s, alnico or ceramic. I have 2 pair. Geoff

Yes, I believe I could own the best Wharfedale E70's in existance. In my opinion, they are the best sounding speakers I have ever heard by far, to this day. I have listened to all the new rubbish speakers in a desperate attempt to find replacements for my speakers if they ever*sob* die... I have been suffering some....................stress over what Im going to do if I cannot find suitable replacement parts at some stage for my beloved speakers. If this isn't possible, the only thing I can think to do is buy a Mackie PA system(YES, PA system!) as they are the best sounding speakers I have heard besides my own.
