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 4.7 out of 5 by 20.
Rated 5 out of 5 by from Vifa TC9FD-18-08This small speaker packs leading technology and sounds as good as expected but of course don’t expect spectacular high frequency what you get is a fullranger with an excellent sound and balance for a few bucks and happy to have bought them (way better than my 5” Fostex). I have mounted them on a 4” diameter white drainage PVC coupling adding two lids to close the box making a volume close to 1 liter all tree parts are available in Home Depot or other hardware store for less than $3.00 Dollars. Just open a 3.060” diameter hole on one of the lids for the speaker mounting from the inside and a small hole on the other lid to exit the cable pair add pillow stuffing on the inside and glue both lids to the coupling this makes a sturdy and non-resonant cabinet. I left my boxes with the natural white color of the PVC so no need to paint or do other finishing work. As a finishing touch you may want to make a wooden support for the cylinder cabinets and they will look great!I’m using my pair as a close field PC speaker and if I would ever need lower bass I can connect a “sub”-woofer I have from a PC speaker set BTW the speakers are connected to a small chipamp (TDA7297Q) that I made for the PC which will drive this 8 Ohms speakers up to 5 Watts at less 1% THD. They may not be party speakers as fullrangers but highly recommended for near field application such as explained.Enjoy!

Rated 5 out of 5 by from I like these a lot!I've built two different systems with these. One uses eight per side, arranged vertically in groups of four with a compression horn tweeter in between. Crossed over before amplification, they cover from about 200 Hz to about 5000 Hz. With a subwoofer covering the lows, these blow away the typical "speaker-on-a-stick" 2.1 system . With just the slightest EQ, these provide near HiFi results, and they will get plenty loud enough for a large backyard or small gymnasium.The second speaker in which I've employed these is a stereo pair that I've been told can pass as a studio monitor. In fact, the more I listen to them the more I prefer them over my Mackie HR8s.Accurate, loud, not at all expensive -- can somebody tell me why I might want to spend more for something else in projects such as these?

Rated 4 out of 5 by from Surprisingly good sound!I am designing a sound bar and used two of these speakers as the main stereo pair. To test their function, I connected them to a 35W per ch amp and turned them on. I near fainted. They had amazing vocal presence that I usually only hear in my very expensive pro sound speakers. I wasn't expecting much, but I ended up getting a lot more than I paid for!

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 The best value for moneyWhy Granite is a very common reaction.A good choice if you think the price of others.Be installed in the home or car is recommended for small sizeVery good price considering the performance and design selection

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

I've just purchased a pair of the Vifa TC9FD'S  for th sole purpose of making a scaled down version of The Paul Voight - Tapered Quarter Wave Tube system. But I have to ask: do I need to install a filter of some type between th amp and th Vifa driver? 

Asked by: thcatt
I am not familiar with that design specifically. If the driver is being used full range, a contour filter will help with baffle step and create a smoother response, but ultimately it will be up to you and how you like the sound. Not having a filter will not hurt anything as long as the driver is not overpowered.

So I put the specs into a calculator and it was giving me all these crazy readings. So what would be a good size and port dimensions for these in order to make them into good computer monitors.

Asked by: kyle1
The recommended vented box volume for this driver is 0.206 cubic feet with a 1-1/2" diameter, 1-5/8" long port for a tuning frequency of 89 Hz.

Would a 3.5" hole saw be too big of a hole for this speaker?

Asked by: dholt44
Unfortunately yes, the frame itself measures 3.5" so it will likely not seal properly if a 3.5" hole saw is used.

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.
