I tested my boominator today. The lid was only being held down by some weight and it was placed on an open field in my garden. It was fairly loud and you could feel the kick in your chest from one meter away, but I still felt it wasn't loud enough for a smaller party. My amp is a Ta2020 and I used both my phone and my netbook as a source. The netbook was a bit louder, but began distorting at the higher volumes.

I've gotten the impression that other boominator owners are very impressed with the loudness of the speaker so I began wondering if something is wrong. I'm pretty sure everything is connected correctly, although I use plug'n'play (spadestik) for the wiring instead of soldering.

Which amp are you using? The interesting thing here is if the input sensitivity is set correctly.

The amp is a Muse M20 EX2 - TA2020. I am unsure of the actual meaning of input sensitivity and I definetily don't know how to "change" or "regulate" it. Can you put this in rather simple terms?

The MUSE is fine. Not sure if you have a problem or not. Please put the top plate on properly and test again. Then try and speak to yourself in a normal voice. That's always a good measure of how loud things are because when you have clean sound you can turn up volume very far without noticing it before you actually try to speak with someone.

I just bought this one, and would like know if the Lepai amps still have problems, or if it is fixed?

Yes they do. And that one certainly has problems as that's the old version.

Gain.
Increasing gain of the amp or adding a preamp are things that you might want to think about.

From 5v powered sources like the phone/digiplayer and like the 5v rail inside the netbook, the digital volume control begins to clip itself if over about 70%. However, the majority of power amps are still using outdated gain factors that don't support modern sources and can't get the amp up to potential. This combination is not enough output to push and not enough gain to help.

For adding a preamp, you can try a small signal op-amp as a preamp just like the CMOY and related projects for battery power headphone amp because that is really similar to a preamp.

No. Afraid not. They're completely different.

There may still be resellers in southern Europe, eg. Greece, Italy and Spain, and in eastern Europe, eg. Lithuania and Romania that have them available still. But inquire and get confirmation before placing an order.

Otherwise, the only alternative is Goldwood GW-1058 which is only sold in North America, so you have to import it from there.

If you don't mind spending more but also cut at least 10kg of the weight and gain about 3dB more sensitivity then you can get the Eminence Basslite S2010 instead. It requires moderate changes in that the port should then only be 24mm not 36mm but otherwise the same size. You also have to find a pvc tube that fits over the magnets, and cut to the right length so that the drivers are connected.
