## Description

Review: Can't Go Wrong ! - Fast dispatch & delivery. Box came a bit damaged but contents inside arrived all good. Speakers do look nice but don't expect JL audio or Pioneer sound qualities here, For the money its a winner for decent sound compared to stock if your on a budget. Go for it! Bass response is not the best but mids/highs are solid for its price, get a subwoofer if your after bass Lol
Review: Great stock upgrade - Actually very good little speakers. Ideal as a straight head unit upgrade due to the RMS power being around 25w. Combined with high sensitivity, these are great little swap outs with no need for an external amplifier.

### ⭐⭐⭐⭐ All appears good with the product
*by G***T on 31 May 2013*

All appears good with this product although when received the box looked like it had been kicked around a car park and had obviously been previously opened with very little finesse. Saying that the item came quickly and speakers seemed undamaged and in good working order.
