It can be tricky to work out exactly how much a BigE cab will cost as it will depend on the exchange rate at the time and how much you get charged on import duty. I think that my MAS45 ended up costing £700, which wasn't far off the cost in US dollars. So as a guide, the price in US dollars will be pretty close to the cost in £ Sterling after import duty is added.
So, they aren't cheap cabs..... but I am very happy with mine and have never, ever felt that I paid too much for it.
What I love about mine is the note definition & separation you get, especially from the B downwards, the sheer volume you can get before feedback kicks in and the small form factor and weight. For my needs, it really is the perfect package.
Before I bought the BigE, I was using a BFM Omni10.5, which is a great little cab by anyone's standards, but I often struggled to hear myself clearly on the A and E strings. I thought I needed more volume, but after trying bigger amps and doing a shedload of research, I realised it was lack of separation of the notes in this frequency range that was the problem. Mike calls this the note 'envelope' and it was his discussion and explanation on the topic that alerted me to the BigE cabs in the first place.
I've used this cab a lot as backline (so not going through the PA) in pub gigs and it's done an amazing job considering its size, but where it really excels is as a monitor on a proper stage, where i can set it upon a stand at shoulder height, about 8-10ft away, and get a fantastic sound which sounds like my double bass and doesn't boom or feed back or generally turn to mush.
