Cabasse Dinghy 221 drivers
« on: 19 Jan 2023, 05:46 pm »
If you are so lucky to find a good condition couple of Cabasse Dinghy 221 you’ll have the chance to take off from the original poor cabinet and reuse one of the best large bande drivers you’d meet in your life.
The 221 was a very cheap French speakers in the 70’s.
I bought 2 pairs of its drivers on EBay at a very cheap price. You won’t believe me if I tell you that the drivers frame is in plastic (you read well: plastic) the cone is in paper and the suspension is in paper at the same.
The materials cannot be cheaper.
The sound is astonishing!!!
Fast, detailed with a mid and high cristal and extremely transparent.
The bass is light but you cannot imagine what happened when I put two drivers (one in the front and one in the rear of the speakers in a TQWT cabinet.
The bass came out clear and deep, fast and detailed as much as the rest of the range.
You just have to close the speakers in order to cross the drivers direction 50 cm  in front of  your nose.
Of course you cannot have the same classy sound of a Fostex or a Lowther but with just some coins you are able to enjoy an incredible performance.
the efficiency is very high (95 dB declared) so even a very low powered ampli is enough to drive them at the best (I use a 8 watts single ended Audio Note Oto)

Well, this FR driver looks a great speaker with the right materials.
These materials you mentioned are the best to the purpose of sound quality.

The best sound material for cones are paper, not plastics or aluminum, I have the Beyma 5MP60/N and his polypropylene cone delivery a plastic sound in many tracks and an alu cone will delivery a neutral sound at best.

Many great FR drivers use paper VC former that are light and delivery a very musical sound, but not heat resistant as the usual Kapton VC used in pro-audio woofers.

The best material for basket are brass, second Alu, after some plastics frames as used by MarkAudio.

Old-fashioned FR drivers use suspension in paper, accordion, fabric etc.
The Visaton B200 is a good example:

Hallo boys !
This evening I’ve fitted my lab cabinet to the Tang Band W8-1772 to get a correct idea about its sound.

I have to say that I’m really satisfied. I’ve left the speaker (one only) for some ours with a cd under repeat.

Right after I took a brief audition with some of my references both in cd and, mainly,  in vinyl.

The voice is very nice both in women and men. I’ve felt a “comfortable” sound but it was important to hold the eyes a little bit lower the driver center in order to avoid the inevitable “papersound effect” of the large band drivers.

I have to say that , due to the not dedicated box” the mid to bass frequencies weren’t too much equilibrate.

I’m sure that the not tuned back horn loading caused this inconvenience.

By the way I have to say that the first audition made me very happy about the potential of these drivers.

In the next weeks I’ll have to take the decision about the cabinet I’ll build up.

There are mainly two types that I’m very curious to test. One is a TQWT and another one is a TLML.
The first one is a well known solution that I’ve already used with the Cabasse. The second have a great sponsor (Bob Brines) but, to be honest, till now I do not understand the working principles so I’d cannot tune it if I’d meet some problems.

I’ll keep you updated.

Paolo

If the Tangbang have a low Qts you could use the new frugalhorn from Planet10 for big drivers,   it have a new name.

They are very nice to look at.
Unluckily I have no much space as you can see and, moreover, there is “mein Fuhrer” at home that I don’t think will accept something like these…
All we male play the same game, my friend !

Bob Brines built my FTA-2000 floor standing single driver transmission lines (TL) 18 years ago, that I'm still using but my understanding is that Bob has retired from building speakers.  TL's are complex to design, Martin King developed a MathCad application that finally took TL out of the trial and error stage (that Bob used).  But TL's are relatively big but superior to most other speaker design types.  My TL's use Fostex F200a drivers, very nice but no longer available, beefier and smoother compared to your Tang Bands.

Given the continued searching for Bob’s ML-2000, Scott designed a similar box as replacement — Bonnyville.

Well done plastic baskets are very good and better than many cast Al baskets.

Do you have pictures of the driver itself?

some audax driver frames are plastic.
