I don't have an answer to your question. But i would consider using passive speakers and a separate amp setup. That will take some weight off your stands, and, the bigger advantage, you won't have to run power and and audio cables to every speaker location - just to the amp setup. Simple speaker wire (lamp cord) goes out to the speakers.
we've been using this amp with some small behringer 1C monitors (JBL control 1 knock offs - more or less) for an inexpensive solution that performs surprisingly well (a bit lo-fi - especially the monitors): http://www.bhphotovideo.com/c/product/597468-REG/Pyle_Pro_PCA3_PCA3_Mini_2_x.html we have a bunch of stereo kits that can be combined for multichannel use or used separately. - something like this is more pro: Rane MA4 4-Channel, 4 x 100W Amplifier MA 4 B&H Photo Video<http://www.bhphotovideo.com/c/product/362083-REG/Rane_MA_4_MA4_4_Channel_4_x.html> and there are a lot of surround sound receivers that will do the trick nicely with 5 or even 7 channels of amplification in a single unit. Many even have calibration routines built in. But it's hard to find them with discreet analog input these days - I would look for that or be prepared to deal with getting a digital multichannel input to the receiver. jim On Thu, Jun 30, 2011 at 9:36 AM, Franck M. <[email protected]> wrote: > I'm designing a mid-size (8 to 12-ch) ambisonics setup, using small active > near-field studio monitors such as Fostex PM04, Focal CMS40, BM-5A...(the > exact model will depend on the funding I'll get for this project). > > As it is supposed to be "portable" (well, transportable would be a better > term) I'm planning to put the speakers on stands (such as lightning > roll-stands from Manfrotto) that can be easily folded and put in some car > (mine). > > For example, the 12 speakers setup would have 3 speakers per stand (floor, > mid, ceiling speakers), each stand being in the corner of the room or, > better, at the middle of each room side, in order to prevent that common > room-corner-ultra-bass-boom effect.
