Compact and versatile without sacrificing performance.

The Alpha P3 is a small two-way bookshelf speaker that connects to any stereo or home theatre system to fill the room with powerful, crystal-clear sound. Featuring a custom 4” (102mm) woofer and aluminium dome tweeter that uses a waveguide to perfectly match the low and high frequencies for a smooth transition, the P3 delivers improved directivity and flattens the frequency response for a more natural sound. It also leverages specially textured woofer cones and a unique port tube design that uses bass flex to add back energy and extend the bass frequencies even lower and without any distortion.

  • ¾” (19mm) Black anodized aluminium dome tweeter with front waveguide
  • 4” (102mm) Textured polypropylene woofer with rubber surround
  • Bass reflex cabinet design with a rear-firing port

Hear beautiful texture and detail
All new Alpha Series models employ a ¾” (19mm) black anodized aluminium dome tweeter that extends the high-frequency response beyond the Alpha’s original measurements and minimizes distortion for a rich, balanced listening experience. A waveguide on the front of the tweeter works to perfect on and off-axis performance while smoothing the response for improved resolution and detail. The ferrofluid cooled tweeter on the P3 has also been precision engineered to sit below the woofer to provide precise stereo imaging at any height.

Powerful woofer with dual layer voice coils
At the heart of every good speaker is a great woofer that produces low distortion and high output levels. With the new Alpha Series, the 4” (102mm) woofer employs dual layer voice coils with a very powerful magnet structure and a cone that is made from a special textured polypropylene compound that prevents breakup. With bass reflex loaded through Paul’s original port tube design from the ’70s, the woofer adds back wave energy to extend the bass response and improve efficiency down to 43Hz.

Custom-built and perfected
The Alpha Series’ new crossover wasn’t custom designed to simply just direct low and high frequencies to the woofer and tweeter. It was re-engineered to control the directivity and flatten the frequency response while utilizing an unusually complex Acoustic Linkwitz-Riley filter design that is designed to get a perfect blend between the drivers and keep distortion at its lowest even at high volumes.

Unique modular cabinet design
The P3 has a unique combination of wall thickness and bracing to control resonances and provide a perfect platform for the driver components. The P3 cabinet’s internal damping material was first used in PSB’s most high-end models, and has now been adopted by the Alphas and positioned precisely for optimum effectiveness. A premium woodgrain vinyl finish and chrome front baffle highlights combine with magnetically attached grilles to provide a rich and timeless design.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes. When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected. Over all the new brushes and filter restored Goophy Euphy back to when we first used her!

Don't be cheap like me - buy these and save yourself the hassle!
Style: 19 Pack
I made the mistake of going with another, slightly cheaper set of replacement parts for our Eufy RoboVac 11S. I did not heed the cautionary tales which lead me having to find replacement parts for the replacement parts. This brand fits our vacuum perfectly - the corner brushes don't pop off, the filter is the right size and the roller brush gets sufficiently tangled with cat hair so clearly also a good fit. My only concern (and why I only gave four stars) is - surprise! - the corner brushes. Do they stay on? YES! In fact, they is so secure, I had difficulty swapping one out. Here's the peculiarity of the brand - the "whiskers" on the spinner fell out. I found them all over the floor, on different surface types and under various conditions; they were not getting caught on any one thing. Not all at once, but over two or three uses, one of the corner brushes had become devoid of almost two entire spokes! Ironically, the little guy can't seem to pick up his own mess but I digress. Without the whiskers to grasp, removing the part was difficult. I ended up using a small flathead screwdriver for leverage to pop it off. While the other corner brush appeared to have shed some whiskers as well, it was not in need of replacement. Despite the shedding, this will be my first go-to for replacement parts next go round.

Essential!
Style: 19 Pack
After about 2 months of daily cleanings, the side brushes were looking a little ragged on my Eufy 12. The brushes included in this kit did come out a little bent, but as shown on the product page, when I dipped them in hot water they straightened right out. Intrigued, I decided to try that with the original brushes. They cam out looking like new! The only con is that the filters don't look like a perfect fit. The foam seems very minutely smaller than the original and the pleated filter seems slightly thicker.
