I still have to name these subs and this project
Once the (10) 4' x 8' (40mm thick) Baltic Birch plywood comes in, I'll start the construction thread...
In the meantime, while I wait for the wood to show up and the cuts to be made, I want to revisit the amplifier choices and wiring of the subs. I also want to solidify the EQ choices.
So now that I know this project is going to involve 8 LMS 5400 drivers, using 4 sealed subs with dual opposed drivers, how would you wire the drivers and which amps would you utilize?
One consideration is:http://www.labgruppen.com/products/p..._installation/
In the wake of the global success of the PLM 10000Q Powered Loudspeaker Management system, Lab.gruppen have developed a powerful new addition to the range, the PLM 14000. Built around a two-input, two-output platform optimized for high-power requirements, the PLM 14000 pumps a massive 7000 W per channel into 2 ohms and 4350 W per channel into 4 ohms, making it ideal for demanding subwoofer and low-end applications.
As with the two-input, four-output PLM 10000Q, the new PLM 14000 integrates Dante™ networked audio distribution, Lake® drive processing, and load verification with real-time performance monitoring into a single 2U hardware unit plus unified software controller. The PLM Series is now the exclusive hardware platform for new Lake processing, and the addition of the PLM 14000 enables even more complete and extensive system solutions built around this unique combination of technologies.
I realize this is an expensive amp, but I am trying t oacertain whether the onboard processing can do an LT transform. I'm also wondering if two of these amps could sufficiently drive four of these subwoofers. It may be possible to get these amps at 'cost'. I'm also trying to see what sort of subharmonic filter (non-bypassable) is built in. As we know, QSC Audio is flat to about 5 Hz, while Crown is flat to about 8 Hz.
Anyway, these seem to be great amps, the question remains about whether two of these amps can do the job, or if 4 would be neccessary. Also it would be appealing if the the oboard Lake processing can do an LT transform.http://www.labgruppen.com/products/p...ke_processing/
Then we have the QSC Audio products:
By the way, what is the QSControl.net™ BASIS / RAVE / DSP all about??http://www.qscaudio.com/products/net...lnet_basis.htm
QSC Audio chocies?
