Roland has never used any spec but RMS.... No hype numbers.

The BA330 is 15 watts a side RMS... it delivers 109db, and can cover 100 people.. The bass is decent and has a better overall sound then the Bose..

The mixer is way better than the Bose and has routing options..

The stereo does work well... they are slightly angled ... left and right... and you can widen the effect with control knob... I never needed to..

It is the true swiss knife of amps..

Battery life of 10 hours.... not the 2-3 hours you get on other brands....

I owned and used it every day for primary sound... The critics have not..

4- 6 1/2' speakers and 2 tweeters..

Sorry guys , but I know what I am talking about..

BTW: when using an external mixer (My Edirol).. the volume level far exceeds my expectation..

I was looking at the new Bose S1... but they are so vague on stats as usual... and Bose actually recommended the compact for 100 people over the S1..

If DNJ didn't talk me into selling my BA330 to him... I would still have it..

I keep my eye out for a bargain deal on a used one... there are none... people keep them..
