the box pro Achat 115 Sub

At first, I purchased one of these (with the intention of buying 1 more later).
The sub was driven by 1 channel of a t.amp E1200 (800w @ 8ohm), and the sub really kicked hard- I was so impressed I immediately bought the other straight after testing the first.
Unfortunately for me, and perhaps a percentage of others - if you choose to use the sub on a different speakon pin set (Set 2, in my case), you have to open up the back plate and resolder (Usually the spade crimps aren't easy to pull off, or don't go back on very well), the resoldering isn't an issue if you're capable - but it would be nice to have a pins selection, like the 18" version.

Fast forward a bit - the subs are now being run on a Powersoft M30D (Martin rebadge), and the sincere quality and detail that the subs are capable of really shone through. They really do punch, and they certainly dig a bit.

A small thing about the drivers in these enclosures is that the pole vent does whistle at high excursion - which is unnoticeable if you are running tops as well, obviously.

Highly recommend this sub - great performance at a nice price.
