Default Fostex FF 225 WK for T.V. and Movie's?

Hello everyone. I have been looking at this driver for awhile now. Well I am thinking of getting a pair of these drivers for t.v.and movie dutys. I just am looking for an easy driver to work with. I will add a super tweeter at 5, 000 on up. What type or kinda of tweeter I have no idea? The main reason I am looking to build theses is the t.v. is not loud enough and this speaker is easy to run with a few watts. So tell me what you think? N.S. I will be putting them in a floor standing tower.

Are you planning to use the TV as the amplifier ?!
The effort spent in making high efficiency speakers using 225WK and supertweeters might be overkill for the TV amp.

Go with a Tang Band 1772 8 inch, play way louder and no tweeter required!

The FF225WK has a smooth sound that will not cause fatigue and it will have good bass in a simple bass reflex enclosure. Bass is important for movies, hence it should work well, probably better than the suggested tang band unless you have space for big boxes.
Indeed you'll need a tweeter that you may be able to cross higher than 5K.
But, I think you should not connect the speaker to the TV amp as previously noted. use a cheap digital amp perhaps.

I've used FF225WK for a good while for TV and movies, did a good job of it. I had them in small Karlson enclosures, which helped loading them on passages with lots of LFE, but a simple reflex should be just fine if you don't go nuts with volume. A QB3 alignment (37L tuned to 48Hz) looks good to me. A super-tweeter is indeed a good idea. I've made the little FT17H work on them.

The FF225WK is at its best with girl-and-a-guitar, jazz trio, small-band classical. It needs a tweeter and the FT17H is a good match. If you only watch network TV, the FF225WK's will be plenty loud enough. If you watch action blue-rays, you will definitely need a substantial subwoofer.

For this application, the W8-1772 is a better choice, and once you factor in the mandatory tweeters, it almost the same price.

Does it offer better bass than the FF225WK?

Well of course that depends on the enclosure, and since the 225 is the only one the new WK series I've not yet heard, I guess you could decide whether the following tells you enough;



In US, the TangBands are not quite twice the price of Fostex - but due to the vagaries of international distribution, tariffs, etc, that price differential might not be global.

To expand on an earlier question, were you considering only 2 channels, or planning ultimately to expand the system to full blown surround system?

After some disappointing results with an earlier compromised attempt at multichannel HT rig, I reverted to stereo pair of FE167E, powered by mid powered tube amp. Then about 2 years ago I took another stab at 5.1 with a newer HT receiver - man have they ever come a long way in the past few years, in terms of feature set, ease of set up and performance value. Any way, I'd never go back to 2 channel only, even if only for broadcast TV. Thanks to highspeed / HD cable service, the quality is more than good enough for my own needs - of course hard-core cine-philes would scoff at that, but just call me a honey badger (OK. I'm not that tough, but I sure don't give a .... what others think)

Oh ya, I think Bob & others have already said that the W8-1772 doesn't really need a tweeter, thereby narrowing the "final landed cost" of the system.

There are other issues with the TB-W8:

1) As an 8 incher, high frequency dispersion is narrow. Beaming will not be pleasant particularly in movie applications where widest dispersion is preferred.

2)As Bob mentioned earlier, the highs definitely need to be tamed with multiple passive components. The 225 WK can be run without passive filters or crossovers and the supertweeter can be high passed with a single inexpensive small cap and resistor. Even a ribbon tweeter like Neo Cd3 can be used for widest dispersion.

To the OP, when watching tv or movies even at lower volumes a small sub will help substantially. Get a used home theater amp in the 5.1 variety. Craigslist and $50 will get you a good ampl. Run it 2-channel stereo with the sub and be happy. It opens up the available speakers for you since you have the amp.

I have tried my hometheater with full range only speakers. Had 5 FE167E in the recommended fostex cabinet. Sounded good but when I added the sub it was eye opening. YMMV
