GoldwoodSound GW-205/4S Shielded 5.25" Woofer 130 Watt 4ohm Replacement Speaker,Black

Muy buena acústica especialmente en bajos aunque el rango audible es hasta unos 8000 hz

Awesome speakers in combination with peizo tweeters and a tuned custom bass reflex box. Get smooth responce down to 35 Hz. Just watchout for You Tube as their ads come on sometimes 8x the volume of their normal content.

Had to find replacement 130mm speakers for my Aiwa SX-N9 system and these are an exact fit size wise. The originals were 6 ohm, these are 8 ohm which is ok. Just had to alter the negative connections to fit the narrower spades with adaptors. Tested with a range of music from heavy to orchestral, excellent sound, as good as new.

It seems like every speaker in my house is starting to degrade, mostly in the same way. The rubber surround on the woofer is turning to either mush or cracking and falling into pieces. It used to be that when this happens it was the death-knell for the system, but then folks started selling replacement rubber surrounds. However for the same price of that kit, you can often get a brand new speaker.That's what happened here. For a mere 15 bucks or so I now have effectively a new BA 790 speaker system (which I LOVE!). As others have mentioned, there are a couple bumps in the road with this specific replacement:1. The rear of the sheet metal doesn't fit quite right into the opening in the box. Not really a problem, just center the speaker and tighten the four screws incrementally to pull it down into circumferential contact.2. The terminal on the (-) wire is wider than the push-on connector that's in the box. I used a small diagonal cutter to trim the terminal, then it slid on on easily.3. If this is the first time you've opened your BA-790, you'll probably find that the wires seem too short to allow access. The solution to this for me was to remove the cover plate and push the grommet through, thus giving ample slack to the wire. Open yours, you'll see what I mean.The sound is great once again, no more shattered bass, clean but rich. Totally worth it. I have a couple other BA-790s in the house, I'll buy two more speakers so I'll be ready once they fail, which they undoubtedly will.BTW for those who are not familiar with the BA-790, it is a 3-speaker system designed for computers but works really well with TVs. Unlike some of the boom-makers that are currently on the market, this system is well balanced with excellent treble and bass definition. If you can find a used one on Ebay, buy it, and replace your woofer when it needs it.

I used this to restore an old, inexpensive Infinity RS-series speaker. This speaker was nearly an identical match to the old one, although I had to trim back each of the four corners of the metal basket by around 3/8 inch, and I also had to remove the seal around the front of the frame in order to get the plastic Infinity front trim piece to fit. But when it was all done, it sounded better than when new, and it looked cosmetically perfect even with the grill cloth removed, like it was manufactured that way from the factory. My friend was totally happy with the result.
