SonyXSMP1611 Marine Speaker Dual Cone, Diameter 16 cm (6.5"), 140 W

Sound quality is good for waterproof marine speakers of this price range.Installation was straight-forward. It comes with a template for cutting the hole - I recall it was on the box itself (we didn't need it as we had an existing hole from the previous, different speakers we were replacing), so if you need to cut holes for them, I suggest you don't end up ripping up the box before doing so.They have been installed on our sailing boat for a couple of months now, without any problems at all despite having been drenched by salt water a number of times.The product doesn't look too plastic and has a good quality feel to it.

The sound is a bit thin but for the money they are okay, the alternative OEM marine speaker was listed at twice the price. Finish is excellent and they are easy to fit. The plastic surround is flexible so they can adapt slightly to a curve, which was important for my application on my boat. On the other hand because the plastic is not rigid it is easy to tighten the screws right through the fixing holes provided, so be careful. That happened when I installed and I had to find a washer to hold the speaker in place.

Fitted to my boat where two of the four speakers required changing. Similar model to the 2 taken out. The sound quality is better that the old ones probably because they have been upgraded.I am very happy with them.

Replaced an old pair of Sony speakers on my boat with these. Marine quality, easy to fit and sound great.

Good relation sound/quality/money. Used in a boat. The last two pairs worked fine 3 years. After, the third summer, they broke.
