Dear Forum,

Many  of the Amels carry a Bose Acoustimass speaker system, either the 2+1 or 4+1 system. Although a good choice of Amel given the space it requires, Bose has this strange thing I always found with Bose in which they seem to think that the higher frequencies (trebles) of music are of no relevance. In other words higher frequencies are almost non-existent in the soundstage of the Acoustimass.
It annoyed me quite a bit as I'm used to speakers that do not suffer from this problem. To improve this I made a simple addition that makes a big difference in the sound quality of the system. By no means I will pretend this is a "audiophile" solution but the clarity of music really improves.
It involves ordering two tune-up tweeters from Pioneer via eBay. This model is not available in Europe or the USA but via eBay you can simply order it in Japan.
 See the enclosed picture for the model and they way I added it to the satellite speakers. No drilling, just stick them to the satellite speaker (de-grease the speaker first!). The cable is shortened to something like 10-15 cm and connected in parallel to the Bose satellite (just stick the the cable with the other cable in the back of the satellite speaker). Do mind the positive and negative leads though.

The tweeter-set is around 150 euro and mounting it takes 1 or 2 hours as the mounting studs of the Bose are a bit finicky with hard to reach screws.

Hi Philippe,

Although Im not a big fan of Garmin as a brand the Fusion-line of radios is a nice choice. This one has a touch screen, 4 stereo channels (2 with amplification and 2 line-out channels). It has some specific boat characteristics like storing preferences even if power (12 volt) is completely off. The Bose Acoustimass 2+1 has no internal amplification and relies on the amplifiers in the radio. I added a separate slave amplifier to drive the Bose set I installed in the master cabin. Some Amel 54s have this set factory installed but I think in this case it uses a separate radio-unit in the master cabin.
So for us we have three pair of speakers (Salon, Cockpit and Master cabin) with the master cabin utilizing a slave amplifier behind the mirror at the vanity in the master cabin.
In the cockpit we replaced the horrible speakers Amel installed with a few 4 inch models from the brand “Kicker” (ignore the cat in the picture). There are very few 4 inch models with decent sound quality. The Fusion brand has a few as well but the (sound)quality of the Fusion speakers Fusion is quite poor. Putting the speakers in the cockpit does mean you need to slightly enlarge the hole available but they do fit nicely in the end.
You can even add DAB+ to the radio (digital radio) if you live in an area when this is available. For the USA they offer a Sirius receiver. The power output of the radio is adequate for the Bose speakers. It connects to a a network and you can have an app on your phone to control the radio.
