Vifa BC25SG15-04 1" Shielded Dome Tweeter
Vifa BC25SG15-04 1" Shielded Dome Tweeter is rated 4.4286 out of 5 by 7.
Rated 4 out of 5 by from Replacement for Old Paradigm Monitor Series ~'93?Excellent though not direct replacement for the hard to find (and if so, extortion-priced on ebay) stock tweeters.You *could* mill them a little and have them sit under the oval faceplate, but I just installed them with 4 new screwholes and they seated nicely. the new holes would not show if you went back to stock. Cutout is proper, maybe you'll take off a hair of the speaker box cutout to accomodate the terminals, but literally, a mm if that, or you can squeeze them in.Nice warm, shimmering highs, no complaints. Back to being a wonderful set of bookshelf classics.

Rated 5 out of 5 by from great dome driver... specially for the price!although i just have a few days with it.. is a good driver for 18 bucks... is articulate enough, sensitive for a 2 way dual woofer set up, a tad bright but smooth and flat overall... it might give you some issues below 2k with low order crossovers, but nothing that hard to work out. you have to be carefull with the plastic faceplate if you are soldering on the terminals, bet nice quality in general... well worth its price.

Rated 5 out of 5 by from Outstanding Value!As stated this is an outstanding value. Highs are smooth and dispersion is very good. There is a surprising amount of true detail for a low dollar tweeter. Output is good and does not break up at high volume as many low cost tweeters do. It is shielded which I needed to replace an old vifa. I could not spend very much money to repair my old speakers but I never expected such an improvment!

Rated 4 out of 5 by from Shockingly good tweeter for the priceFor builders on a budget this is a tweeter option that shouldn't be over looked. My transfer function is 1700hz 4th order Bessel with impedance compensation and the tweeters aren't sounding strained. Others have gone with 1800hz 4th order transfer functions without adding impedance compensation and had pleasant results. Overall tweeter performance that exceeds expectations.

Rated 4 out of 5 by from Amazing!This tweeter really is amazing...To compare it to Daytons silk dome (which is really nice) it is a bit brighter sounding, but still remains smooth throughout. Ridiculously low fs allows for simple 6db p/octave xovers at low frequencies...I currently have them paired with the closeout peerless 6.5" $10 driver in a ported .9 cu ft box xover'd at 3khz and it is absolutley stunning!

Vifa BC25SG15-04 1" Shielded Dome Tweeter

What is the difference between VIFA BC25SG19-04 and this one? Need to replace on Dali Concept 6- crossover point is 3000hz. Dali guys wont help nor provide spares. Do you wonder this one will fit even the holes on the mounting plate being Danish and all?

Asked by: NitinKaushik
This will work well as a drop in replacement for the BC25SG19-04. It will handle that crossover point well and the face plates should be exactly the same size.

will the Vifa bc25sg15-04 1" replace the tweeter in a Pioneer SP-FS51-LR floor speaker

Asked by: skibrew
Without knowing any of the original tweeter parameters, specs or dimensions I cannot say whether this will work as a replacement. You may want to contact Pioneer and see about possible direct replacement parts.
