The question I have is it worth the extra cash for the new D class SYN-DX amp. I was thinking a SYN 6
Without knowing whats there now driving the 6 in-boats and woofer, its hard to say if a new amp is worth the money. However, we can make some comparisons between the original Syn-6 and the new Syn-DX6
1st, if your woofer is a single voice coil 4 ohm or a 2 ohm dual voice coil woofer, either amp will safely drive that woofer. But, we need to know what woofer it is, in order to say whether the amps' 600W rms is a good match, over powered or under powered for the woofer.
for the in-boats. The original Syn-6 is going to deliver about 60W rms to each in-boat, where as the new DX6 is going to deliver 100W rms to each, so nearly 2X the wattage. This is a noticeable difference especially if you are going with a hi-performance speaker like the Wet Sounds 650 series.
The new DX6 has a smaller footprint than the retired Syn-6, making it easier to design and configure the amp wall.
The new Syn-DX line is class-D and MUCH more efficient compared to the class-A/B Syn-6. In this comparison, you could see no more current draw yet with more wattage and possible less current draw for more wattage.
So, if you happen to score a deal on perfectly good working used Syn-4 and Syn-6, then jump! Both are great amps and the Syn-6 will serve you well. But, if you are building from scratch and go with the new DX6 and DX4, then yes, they are worth the money.
