hi

i'm rob campbell and have recently joined the forum. i've owned a pair of nightingale nm1 speakers for some years and have just bought some whopping speakers from ebay -

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=280432037902&ssPageName=STRK:MEWNX:IT

i'd really appreciate it if anyone knows any info about the above 0 i've not even tried them yet as i am not able to lift them at present!

just for info i mostly listen to bbc radio 2,3,4 these days ; i;ve a tandberg 70s receiver , also a quad 22/II setup and a 300b valve amp.

regards

rob

ePrey pimp speak "of £1780 each" NO ~£178 from Nippro?

A "real" homebrew design!

i.e. a pair of Chris Rogers Pro9TL cabinets fitted with KEF B139B, B110A, T27, Coles 4001, which would normally be found in his "rip-off" of Bert Webb's Cambridge Audio R50.

The fun thing is with the drive units at the top, you'll get the presentation offered by Lentek Monitors or IMF TLS80/RSPMs, although the T27 and B110 should have had their relative positions transposed!

Pro9TLS http://www.tech-diy.com/LS_Articles.htm have the bass unit at the bottom and should have a Peerless KO40MRF midrange and an Isophon, Peerless or Audax tweeter.

Rather than the Pro 9, i think you'll find they are based on Chris Rogers' earlier design which was published in HI-FI ANSWERS. That version used the Kef drivers & Coles supertweeter as well as the mid positioned T/line vent as per the Ebay units, though they have repositioned the drivers grouping them all in the upper area of the baffle.

Where were the Nippro versions made??

Both the HiFi Answers version & the Pro9-TL are 13.5" wide!!
I have both sets of plans in front of me as i type having built the HiFi Answers TSL, in the 70's & contemplated building the PRO9s, but instead moved on to other things.

The HiFi Answers TLS, is 1" taller than the PRO9 at 39" & 1/2" deeper at 18", so dimensions are pretty much identical for both of the Chris Rogers designs.

I'm not familiar with the Cambridge Audio R50, i don't think it sold in Aust, but we did have their TL100 & 200 transmission lines. The bigger TL200 was 13"W X 17.5"D X 42.5"H.

hi chaps

thanks for the replies , they are 40.5" high (with some small feet to allow the cables in) , 19.5" deep and 13.5" wide.

i now have them running with quad fm4 , 22 and 2 IIs and they sound very nice ; connecting the speaker cable was a bit of a fiddle - just 2 small screws on each base - seemed much lower quality than the rest of the speakers.

any advice on power handling please? are they designed for a particular max wattage for example? or more relevantly perhaps , is there a particular type of amp that would suit them best?

regards

1. Spend a few quid on replacing the old Alcap electrolytic capacitors, they're probably acting as small resistors after 20-30 years.

2. The crossover is probably a "stock" or higher powered version of the Cambridge R50 unit, so 15W light bulbs, 25-100W solid state.

3. Get a pair of round plate 5-way binding posts and practice with a tank cutter on a piece of scrap wood first.

4. As the single largest user of Quad equipment (according to Quad Service) I'm not allowed to be biased , so stick a Sugden or Croft up their backsides, although they'll be quite happy with most European amplificaion and American muscle amplifiers with care.
They will be "picky" with Japanese amplifiers and tuner-amps, so Pioneer Reference, Yamaha, Sansui and odd sods like the transformer outputted 100W JVC power amplifer, which was the oriental take on the Quad 303/50E without the hassle .

wow , thanks for the comprehensive reply colin. nice to know my old 15watters are in the right ballpark ; they suit my ears for a large part of my listening.

i will look up '5 way binding post' but think its unlikely i will unleash my crude manual skills upon them ; i may be able to persuade others.

may i ask a further question? -

does it matter which brand of capacitor one buys? i am not technically competent either but have read about the deterioration you mention.

many thanks

hearing varies from cloth through brass to silver i would imagine ; i am in possession of an old school a level physics although it has not served me well in the real world.

i recall that falcon had something to do with the nm1 speakers i have. i'm still looking for a picture of them with the foam intact or a drawing as i quite fancy restoring the cosmetics to their original glory.

cheers for the amusing and highly informative reply , its most appreciated.

regards

Finally dump the Quad pre, some of the Croft 3 and 5 series sound much, much better with Quad IIs .
