Vifa TC series overlooked?

[coolkhoa]

The Vifa TC series midbasses, in particular the 3-1/2" and 4-1/2" units, seem to be good alternatives to the Tangband full-range units. Of course, they will have to be paired with some tweeters. But given Vifa's reputation for quality and consistency and the versatility of the TC range, I'm surprised they have not been implemented in any published designs.

Does anyone have experience with them? Perhaps this thread will make them popular...

Post the URL for specs and we'll have a look.

I just edited my post to include Vifa at Parts Express. This link will take you there also.

... is actually a rather nice sounding one, especially for the money, well worth looking at for a good system within a moderate budget.

Haven't used any other TC's yet, one reason being that I have other stuff sitting on the shelf I have to use first.

Well, factor in the cost of parts to get rid of the high freq nasties (especially with the 3.5" model) and it seems less attractive.

slightly larger, but i am about to implement the TC14 5.5"

into a pair of "small" PC speakers, however with a VAS of 10.5L i get a maximally flat response from BassBox in a volume of 12L with a FB of 45 and an F3 of 53

i have only seen them used in a 14Lish pair of 2ways from Selah

the 4" I did a fullrange design with a filter on it at my DIY event.
Dave from Victoria was stunned at never knowing about them.AS he is a MR FULLRANGE
His friend bought them at the event.
I never measured them but I am building another design that I will have up later in a kit.
Simple and very neutral.

Hmm...double posted..tried to remove this one...sorry, I'm a little trigger happy on the clicker finger apparently....

At least for the 4" drivers I would very much rather have the Vifa TC series. I've tested the IMD performance of the Vifa TC11SG-49-08 and the W4-654S, W4-616S woofers from Tang Band. The Vifa woofer beat them hands down in IMD tests centered on 150Hz, and is quite a capablie little woofer. It's a bit more expensive I think, and does require a little more work on the xover, but it is a much better sounding driver in my opinion.

I don't find the parameters of the TC18 series drivers to be all that useful for most of my applications. Either not enough bass extension or not enough power handling, and they don't tend to work well in vented enclosures. The TC14SG is a mighty fine little woofer.

I've never tried the TC08 series...never needed to make that tiny of a box.

I'll try and remember to post the IMD plots this weekend when I have time to go to the other computer and find them. If you guys haven't seen them by Sunday, send me an email or something to remind me. I could forget too.
