Rated 5 out of 5 by from Great for studio monitors too...I bought this over a year ago. I've tested it in a center channel for home audio, and now they are in my new studio monitors I just finished. Even testing it alone, the sound is very nice! You can almost even run it without a crossover because it can handle the power with minimal distortion. I gave it 5 stars because: Price is great. The performance is spectacular. It has a nice magnet with heat dissapating fins which is an innovative design. The tweeter is bright (94db) so I used a good 10 watt non-inductive resistor for my monitors. It has a very clear and precise upper bandpass region too. I highly recommend it. Thanks PE!

Rated 5 out of 5 by from Great, Versatile little tweetersNice compact little tweeters, Great for small to large projects and they're high efficiency allows you to combine them with larger number of different woofers(if they're to bright you can dial them back with a L-PAD) On those compact projects the truncated face plate/horn allows you to mount them up close to the mid/bass drivers where they need to be. I'm using these in a MTM with 5.25" Peerless, 0.5 cu/ft vented boxes, 3500 Hz x-over is a 2nd order Linkwitz-Riley with an impedance EQ circuit on the Vifa BC25SC55's combined with a 1st order Butterworth on mid/bass drivers. "WOW" these are a really good value and can put out alot of crisp, clean sound for the buck. There intended use is computer speakers for my wife. I've also replaced a variety of other tweeters with these little guys and they worked as good or better than the original. You can't beat them for the price. Will be getting a bunch more. Thanks PE

Rated 5 out of 5 by from Very pleased with Vifa woofer and tweeters."the Vifa BC25SC55-04 1" Tweeter is fabulous! Very efficient at 94dB/1W and sounds GREAT!! Got these on sale for $11ea. and used them for a speaker project of mine and am very pleased with them.Also bought pair of Vifa TC9FD-15-08-3-1/2 Full Range Paper Cone Woofer for $4 ea. and they sound incredible for such low price. (what a bargain!)Very happy customer indeed.

Rated 5 out of 5 by from great performance and priceused this on a MTM set up with the Aura 299-030's. Great matchup. Very affordable. went single order X-over. You will enjoy the sound even more as you relate to the low cost of these items. When you're talking about a system with six speakers and crossover components for around $80 bucks, well................ Go PE.

How do you recommend cutting a 1.7" hole? I assume that means a 1 7/10" hole, and not a 1 7/8" hole? Thanks

Asked by: dholt44
Yes this is a 1.7" (7/10) hole. This is just shy of 1.75" and there is plenty of tolerance for a slightly larger opening. You should be able to find a 1.75" hole saw or spade bit to make this easier.

Would these Vifa tweeters work as replacements for the flat bottom/oval tweeters on my B&W DM220s? Is there a better replacement tweeter for these old B&W tweeters? Thanks.

Asked by: joe1965
Unfortunately we do not have a specific cross reference for this type of thing. The B&W speakers are all proprietary and anything after market will likely require modifications in order to fit properly. As long as you fine a tweeter with the same impedance as the original the crossover point will not change.

impedance for two wired in series?

Will two of these wired in series result in a total of 8 ohms? How will that change the SPL - 94 to 90dB?
Asked by: Johnny Reno
Yes you will get 8 ohms, as far as SPL the rating of 94 db is stated in volts per meter and not the normal of 1watt at 1 meter so I am not sure of there rating. Since they are in series each speaker will see half the power as they will act as one.
