Vifa TC9FD-18-08 3-1/2" Full Range Paper Cone Woofer
Vifa TC9FD-18-08 3-1/2" Full Range Paper Cone Woofer is rated 4.7391 out of 5 by 23.
Rated 5 out of 5 by from Works nicely as a mini amateur radio speakerI built this into a somewhat undersized but inexpensive 4" X 4" X 4" plastic sealed electrical box (about 0.8 liter) with acoustic damping. Sounds very good with reasonable efficiency as a mini amateur radio speaker. Unibox spreadsheet says it has an F3 of 135 Hz, and a 2.1dB response peak, not unduly large at 231 hz. SPL predicted at 83.8 dB 1W/1M. Audio sounds full bodied and smooth.

Rated 3 out of 5 by from Good sounding speakerSpeaker sounds so much better than my old one that was blown. No more crackling sound. Although the frame and speaker dimensions were the same, screws holes were just a tad off and I had to re-drill them. So measure carefully.

Rated 5 out of 5 by from Smooth and non-fatiguingI initially got them to replace the front woofers of a 99 Audi A4. The fit well with just a little mounting modification. A little short on bass compared to the stock speakers but then again these are just 3"ers. what struck me is how smooth these sound. i ran them straight off the radio with just a cap to keep them safe from too much bass. i later changed them to larger 4" then 5" drivers for more bass but their replacements just couldnt match them for smoothness.

Rated 5 out of 5 by from 9 speaker bar for home theatre systemSo, i read the reviews, and these sounded worth it. I had some Tang Bangs in my cart that were on close out that were a little cheaper, but before i could buy them, they were out of stock. I ended going with these. I love the sound of them. So what I did was made a spear bar/shelf that has a left, right, and center channel in it. The box for the speakers are 5 inches in height, 54inches in lenght and 14 inches deep. I also made each channel with a tranmission line design. I went this route after reading up on this design and thought that this could improve over all sound quality. Im not done with all the detail of the exterior shelf, but have the box made and speakers installed. Listened to lots of different types of music. Bass was good and hit well on, some drumb and bass music, highs were awesome on some Classical. Not running any crossevers, thought about it, but was waiting to see if there were going to be any issues with the lows, and didnt really hear any issues.

Rated 5 out of 5 by from Crazy Good little speakerWow, what great sound coming from such a little speaker. Can't push them very hard and I would suggest a cap to limit the very low frequencies. But these sound very good. Excellent range and very clear.

Rated 5 out of 5 by from No more ear fatigue!!I bought a pair of these 3.5" full ranges with the intention of making a couple enclosures and having them play full range at my office. Since my building is shared space I didn't want to mess with a subwoofer or a very powerful setup. I also bought Lepai T2020 mini amp to connect the audio-out of my computer. I just have to say that even without ANY box I set them side to side to a pair of Bose 601's I had at home and WOW I now am a believer in SPEAKER manufacturers, Peerless knows speakers, quality, detail in reproduction, instruments I was missing, etc.. It all came to life!! They are better heard ON-AXIS and even in the boxes I made (13 liter ported towers) you can definetly hear bass, not overpowering or mind numbing, but is definetly there... I mean for a pair of quiet office speakers, these things are amazing.. They will take you for a ride. Must have :)(sorry for the unfinished look in the picture, when I finish them I'll upload more)

Rated 4 out of 5 by from great multipurpose driverI ordered 10 of these to build a small footprint LCR bar for a clients new 51"plasma.. paired drivers in separate enclosures, with a driver on each end of the bar, wired each pair together for 4 ohms to each amp channel.. results.. for less than a hundred bucks, awesome sound in a small cabinet. wrapped it in velour and they are very happy, better frequency respone than expected, used no circuitry inside the cabinets whatsoever. a little active EQ and HPF from the reciever did the trick. much louder than expected. very happy, built two dipole surrounds with the other four drivers. can't wait to hear it.

Rated 5 out of 5 by from JUST WHAT I WAS LOOKING FORSo i've been searching and searching for a replacement speaker that wouldn't break my budget for the '88 celica and this speaker is perfect. Though i did have to do some mods to the speaker box, i didn't even mind because it wasn't anything difficult. These speakers are awesome for the price and i would definitely recommend them to anything who needs.

Rated 4 out of 5 by from Amazing ValueIn its price range, these are practically unbeatable, however there are some quirks that are relatively minor.1) I'm not a fan of the shape of the basket. It was rather annoying flush mounting it. A simple square or circle would have been much preferred. This shape is very common to Tymphany, unfortunately.2) The foam padding on the basket is inconsistently glued on. Some edges in fact had a visible amount of glue leaking out. It makes the driver look cheap, which I suppose it is.Still, I wouldn't have been able to guess from the sound this makes that it was a $10.60 full-range. It's such an amazing value that it's hard to recommend other drivers at even twice the price.

Rated 5 out of 5 by from Great replacement Item.I ordered two of these 3 1/2 inch speakers to replace two bad midrang Triads speakers, That I had since the 80's. The delco drivers were nice sattellite speaker with a Luxman amp and pre amp sound was smove until about six years ago. I haul my Thiel 2.2 up the stair to the 2nd floor to listen to my music. And now that I replace the old Triad delco drives with the new Vifa drivers, after about four days of brake in time. The Triad sound great with the replacement Vifa drives. These are now my main speakers. Great sounding drivers.

Vifa TC9FD-18-08 3-1/2" Full Range Paper Cone Woofer

Hi What is the smallest enclosure that you'd recommend? Also, sealed or ported? Since Qts is .89, it should be ported, right? I have planned an enclosure of dimension 8Wx4Hx3D, sealed. Thanks.

Asked by: arjunm009
The dimensions you have in mind are perfect for a sealed design using this driver. If will have an F3 of about 130 Hz but it will extend into the 80's or so pretty easily. Ported will give you more low end output but is about 0.2 cubic feet.

Would these be a good option for a line array driver.  Would a line of 18 of these compare with a line of 18 FaitalPRO 3FE25.  I hear the FaitalPRO's are being used some professional compact array setups.  These would of course be accompanied by a sub. 

Asked by: strander
These will work well in a line array but they will have significantly less sensitivity than the FailtalPRO 3" drivers.

I plan on using two of these in a MTM design. In order to cross them over to the tweeter at 6K hz., would I use an inductor value based on the 8 ohm of each speaker, or the 4 ohm value of the two wired together?

Asked by: BobbyZ
You will want to use the impedance of both together for this type of application.

i have a design on using 2 of these in a center channel with a tweeter (part #279-002) crossed at 12.5kHz and i would like a tuning frequency in the 80Hz - 100Hz range also my design is to have both the midwoofers (this 3-1/2") sharing the same airspace

Asked by: speakerfreak1
I would recommend .32 cubic feet for both with two 1.5" diameter, 3" long ports for a tuning frequency of 82 Hz.

Good choice paired with a small sub for a boom box?

I'm looking to build a boom box and was thinking of using 2 of these per side along with a small 8" or so sub woofer powered by the Dayton mca2250e 2.1 plate amp. Thoughts? Good choice? Would this combination even work?

Yes that combination would work and work well.

Your sensitivity always goes up by 6 dB when you wire two woofers together in parallel. Two of these in an MTM will have an SPL of about 89.5 dB.

Suitable for sealed enclosure?

I have been considering this speaker for a satellite cube project that will be used mainly for HT and music listening. I ran some calculations in a box modeling program based off the thiele and small parameters and the result was negative, which was kinda odd. I am trying to achieve the flattest frequency response possible because these will be used for music listening and I prefer a balanced sound. So my question is this, is this speaker better in an open baffle application and if not what would be the recommended sealed box volume? Also, how accurate is the advertised watts that this speaker can handle? I am planning on pairing two of them with a soft dome tweeter(rated @ 50 wpc rms, 100 wpc max) in each configuration, which will be powered with 120 wpc rms in HT( DolbyII) and 140 wpc in stereo mode. So according to the specs the combined rms watts for each configuration should be 130 and 220 max. I would prefer feedback from someone with direct knowledge of these questions and/or direct experience with the speakers.Thanks
Asked by: btuck
These woofers are better implemented in a vented enclosure however it depends on how low you really need to go with them. With an Fs at 125 Hz, they are not designed to play very low and will work best with a subwoofer. The power handling is accurate although this is only taking into consideration where they are crossed over on the low end. As long as they arent doing much below 120 Hz they will handle 30 watts just fine. Most systems like this will never send full RMS power to the satellites simply because the subwoofer is doing 95% of the work. If you plan on mating these with a sub, I would go ahead and throw them in a small sealed enclosure.

I'm planning to put these in a small set of ported computer mini monitors. Any recommendations on the ideal cabinet specs and port length?

Asked by: Drewfus30
There are many response curves and alignments possible - the best thing to do is plug the specs into an online "speaker box calculator". You can then play with port diameter, length and boxes to see how deep and flat you an make your creation.

What size disconnect terminals should I use?

I will be buying 50 of these for a line array and obviously having the right sized terminals would be very helpful. Thanks for the help!
Asked by: wassp223
If the photo is an actual representation of the driver in question, then one terminal is 3/16 and the other is 3/32.I checked the data sheets, as you likely did. I found no better way than to measure the on screen width of the driver mounting flange across the width and reverse engineer the dimensions for the terminals. I would have to measure one physically to be more certain than that.

Has anyone worked out a notch filter for the bump at about 8.5k ( per Zaph)? Thanks

Asked by: boone
I had a similar fostex speaker. The notch at that frequency turned out to be baffle compression, widening the hole around the driver or mounting the driver behind the baffle should fix it.

does the high end roll off as weak?

The price really makes me want this one to work out for me, however the 15khz(+) cut off is hold me back. Honestly, would I be much more satisfied if i dish out the extra $17 for the Peerless 830986?
Asked by: Project addict
I guess i am getting deaf all cheap 3.5 in drivers need a good x'over and a tweeter for me. I use these with a 4 k xover in the poly type 3.5 [love them ]open accurate but realistically a small cone cannot move the air accurately at 15k with out beaming or below 150 hz with out distorting or loosing contact with the air. they came with 45 uf installed to block low bass. snipped it off made a 12db xover and 2 good tweeters L-paded and a dayton150 amp,mated the speakers below the 24 in pc monitor where the drivers sound field was best then mounted them, lip sync is awesome and the dual 18 in sub in the den with main's shake the icing off the cake
