Default Cyburgs-Needle using W3-315SC

I’m planning to make a Cyburg Needle, I have recently tried to build an LongTall speaker whit pour result. So before I start my next little project I will try to fool-proofe my construction before I start.
In my LongTall I used a TB W3-315SC, and so comes the question.. In all the Cyburg-Needle designs I have seen so far they all use the TB W3-871S.
Will it also work well whit the 315SC?

From the answers (or in this case the lack of answers) i conclude that there isn’t any that have tried the suggested construct using the mentioned driver.

Is there any way to figure out if there is a match coupling, the w3-315SC and the Cyburgs-Needle?

I have been reading of a needle-design with Visaton FR8. But i wanted some better bass, so i made them some wider and fitted Visaton's FR10. Its was my first diy fullrange speaker project. All dimensions are allmost the same, but width now 13 cm. Now its not a needle anymore, but can be considered as "Cyburgs Pole" or something like that.
Very nice sounding, especially the stereo depth because of lacking crossover filter. The hill in the frequency curve has to be filtered though with FR10. No dig. camera at hand unfortunately.

Hi Marius

I have analysed the Needle, and the performance is the same with the Tang Band I have tested. However, the Needle is not a construction I would start búilidng - just my own personal opinion.

For some there is a reason: its price.

The FR10's cones are treated with dampening fluid from Visaton: LTS 50 against coloration (I am used to Bextrene woofers)
For Tang Band units this is not nessesary.

as you can see from the simulations in Bjohannesenäs post the W3-315 and the W3-871 perform almost the same in the bass region in the needle. Beware of the high of the W3-315, many find it too much.. I personally prefer the W3-871 is I have to listen for more than 5 minutes

btw: based on simulation (I have yet to build my pair of needles) the Omnes Audio BB3.01 perform surprisingly well in the needle

Default BB3.01

Does the Omes Audio BB3.01 need another filter since the parameters differ a bit from the TangBand

yes, I built them. performed very well. as expected the highs are much better than the W3-871S, but also the low is better (but only slight). The W3-871S is still a fine speaker, but imho the BB3.01 is well worth the extra money
