Good LX-5 replacement
These seem like a great value. Very clear sound for not a lot of cash. I realized that the foam on my LX-5 woofers was starting to tear, but at these prices, it's better to upgrade the woofer than to try to refoam.

The old woofers sounded a bit "muffled" compared to these. I measured a bit more upper-midrange with the new ones, but they do seem more clear. Bass is especially more detailed. Volume level seems to be about the same, which means that the tweeter is still overpowered a bit, but if you were OK with it before, it'll still be OK, only the mids will be more clear and with better bass. The tweeters seem to be a bit more audible, but they are still recessed a bit. Stock speakers are very boomy in the mid-bass; I stuffed the cabinets with some polyfill to combat that.

These were a perfect fit for the LX-5. Opening the front of the LX-5 is a bit tricky, but tips posted on AudioKarma were helpful. This is not a difficult job.

Excellent Value X 6
I had 8 RCA Optimus Pro LX 5 speakers with deteriorating surrounds and I read this speaker was a direct replacement. It's been several weeks now listening to my rebuilt speakers and they never sounded this good even when new. This is a fantastic speaker for the price and it's shielded just like the originals. The bass is far superior and even the mid-range sounds improved which is saying something for a two way compact enclosure. The replacement was effortless. I suggest you do not even bother with the free gaskets they supply. My only complaint was I only bought 6 instead of 8 because I really only needed 6. Shipping over $100.00 is free so this was an incredible bargain and now I wish I had purchased the extra 2. Fantastic price, fantastic sound and an effortless replacement.

Optimus Pro LX-5 Replacement Woofer
This speaker driver is a perfect replacement for Optimus LX-5 Radio Shack speaker. Fits perfectly with no modification. The best part is that it sounds fantastic... better than the original. Bass is tighter and a little deeper, not to mention that you can play at a higher volume level with no distortion. The price? Only 20.00 bucks. You've got to be kidding me. Highly recommended!

Replacement for Paradigm Alpha B1
This is a drop in replacement for Alpha B1 to fix the weakness in the speaker. The upper midrange of the OEM woofer is lacking, and this woofer is clear and detailed through the operating range, just like the frequency response is shown in the chart. From 55-3000 the output is almost a straight line, it's that flat!!

Perfect fit for Optimus Pro LX-5
This is a great replacement for the Pro LX-5 woofer. They sound much better than the original woofers and literally are a perfect fit. Audio Karma has great instructions on how to replace the woofer. It only took 20 minutes to replace the pair.

Optimus PRO LX5 Replacement
Drop-in replacement for original woofers in a pair of LX-5 MkI.

At $20 ea. only about $10 per speaker more than a kit to replace the foam surrounds on the originals - and these are far superior to the OEM part.

Nicely packaged and included a new gasket for the baffle. More than I expected at this price point. Exceptionally fast shipping by Madisound.

Very pleased with the sound.
