Very good sound quality for the price. Paired with a sub provide well balanced sound with a bit of eq. Without the sub the bass are a bit weak…

Pair them with a good Amp and you’re in for a treat!
These really are quite a remarkable pair of speakers when paired with a good quality amplifier!I originally powered them with a Fosi HT4S and they sounded ok but pretty rough in the midrange. Then I tried a Wiim Amp and they sounded much better, nice and refined and balanced but I just had a feeling they could go further.Then I bit the bullet and got a second hand Arcam SA10 and that really brought them to life! Amazing clarity and such great warmth from the Arcam. They are lacking in bass but as they’re the smallest in the range that’s to be expected.I’ve already decided to upgrade to the Atrium 6 and move the 4s to a quieter part of the garden.All in all a fantastic pair of speakers! Great build quality, fantastic sound and easy to fit. Power them with a good quality amplifier and you’re in for a real treat!

Damaged on delivery
Whilst the box was not damaged the speaker grill on 1 speaker had a big dent.Good sound but disappointed that it was damaged.

Polk sound for reasonable price
Paired with Fosi 20a Pro amp makes for an excellent listening experience in my 10x12 gazebo.

Tenían que ser Polk.
Las compré para ponerlas como surround en mi AVR, tal vez hasta estén sobradas para eso. Antes, las probé como Segunda Zona y me gustó el sonido; en algún momento sustituiré también mis surround traseras por este modelo.Las volvería a comprar para una segunda zona para ambientar el jardín o en el comedor.
