Cyburgs-Needle for Tangband W3-871S

[hm]

did anyone tried the new FRS8M,
better Qts, 87 dB, in the Needle

my alternative is the TROMBONE
http://www.hm-moreart.de/106.htm
better soundstage more bass and max. SPL

Can you please present the Trombone here, with full diagrams/crossover components (if necessary) as a new thread? I am very interested.

The other day, I heard a pair of the Needles with Tang-Band drivers in them, built by a friendly and courteous fellow DIYer here in Iceland. They sound wonderful! Granted, I'm hifi-naive, but these were very convincingly one of the best sounding systems I've heard. Cat Power played beautifully out of the Needles and the Antique Sound Lab AV-8 tube monoblocks.

I guess the greatest surprise was that the 8W amps were enough, after reading that they Needles weren't that suited to low-power amps. I'd sort of imagined that more power would be necessary. Of course, up to the point of distortion the volume was hardly ear-shattering, but there was enough of it by any standards of mine.

The sound was indeed warm, as I've seen it described, and it had a reassuring heft and lovely punch on the drums. Klang+Ton thought these speakers were fascinating, and I believe that I agree, based on their sound, the looks, and the price.

The best educational experiences are those that naturally cause an irresistible curiosity-urge to dive in, learn more and do, and that then bear fruit that you'll enjoy for a long while afterwards, sitting around with good people and cups of tea. A thank-you to Herr Cyburgs for designing these and sharing them, and my sincere show of appreciation for the employed design philosophies. A great introduction to this deep and satisfying hobby, a great way to spend your time.

Edit: and of course, thanks to all the builders and the experimenters for their feedback and parcticipation, the sharing of knowledge and expertise.

Would it be a worthwhile experiment to load the driver of the needle on one of the sides, with the driver the same distance from the top but centered between the former front baffle and the top of the angled center baffle? the port would remain in the same place and now be side-firing. I've seen speaker designs kind of like this, I guess in order to have a larger front baffle. Ummm, thoughts? I guess you lose some of the slender/sleek aesthetic appeal, but maybe not?

Hi,

it could be interesting if one of you built my TABAQ and compared it to the Needle. It is very easy to put together, as I have made it as simple as possible.

One thing is doing simulations - another thing is how it works in real life.

I have not measured TABAQ, just used my ears with test tones and different types of music. I am very pleased with the result (of course, I made it myself. It is like a woman being a mother for the first time - her baby is the most beautiful baby in the entire world).

Please take a look at

Hi from Bjorn

[Solve]

Very nice!
I sure going to build an pair of those.
Just wonder if its possible to use any other Tangband speaker?
Already have one pair 871 in an box.
Have some credits in http://www.hifidistribution.com/
that i want to use.

Hi Solve,

I have tested with 315 and 926

Simulations with 871 does not differ much, so I would expect these to perform well too.

Sorry for stupid questions but, if i want to use W4-657SC is it a new box modelling then?Just thought i maybe get it a litlle bit deeper.

Hi Solve, this driver has T/S paramaters that are very different from the 3" drivers and would need another design or at least, it has to be checked by using Martin J Kíngs models to what should be adjusted. Give me a couple of days.
