Hi All,
I wonder which would be better or simply your choice of amp to drive following drivers (each in it's dedicated sealed box) 2x BMS 18N862 8ohm and 2x BMS 18N862 4ohm?
I am choosing between following amps and I can mix and match:
1. Crown DSi 2000 - 1600W bridged in 8ohm
2. Crown XTi 4002 - 2x 1200W into 4ohm
3. Crown XLi 3500 - 2x 1000W into 8ohm or 3700W bridged into 8ohm
4. Crown XLi 2500 - 1500W bridged into 8ohm
It is almost pure AB for XLi (SMPS + Toroidal) vs less pure AB with SMSPs and AD - DA conversion that cannot be defeated and which I don't need due to MiniDSP in the chain.
I could use XTi 4002 to drive 2 channel 4ohm load at 1200W each and XLi 3500 to driver the 2nd pair of 8ohm drivers at 1000W per channel. Or 4002 for 2x 4ohm and bridged XLI 3500 for one 8ohm (3700W into 1500RMS driver with peak power handling of 3000W - how safe would it be?) and DSi 2000 bridged at 1600W to do 2nd 8ohm driver?
I don't need DSP (as I have MiniDSP Flec balanced) but I don't mind having it.
It is purely on performance front as there are some differences between them I thought.
I have the mix of 2 4ohm and 2 8ohm drivers as I was able to source the 4ohm pair 2nd hand so I went for it (my choice would be 4x 8ohm).
How important it is that XTi can handle 2ohm load while XLi cannot for me if my 8ohm BMS drivers in theory don't dip at all below 8ohm (that question is in case I would decide to bridge Xli 2500 or 3500 in which case they drive only 8ohm loads).
Thanks

I am in a similar situation. I have 2x LaVoce SAN183.04 drivers that need powering. They dip to 6ohms at 20hz, and require 1000wrms to reach xmax. I'm considering 2x Hypex UCD2k monoblocks, one for each driver. That should give plently of power. 2x UCD2k + 2x SMPS3000 + 2x Ghent Audio Case = £1200.
Is this a home audio setup?
The smaller model amps bridged into an 8ohm load is a good way to utilize them, it doesn't matter if they are not 2ohm rated for this use.
I would normally caution against powering drivers to thier peak rating but it depends... in a home environment where you're not likely to push them to thier limits for hours on end there is less chance of exceeding thermal limitations, but... if you're throwing big parties then you should treat the system more like a mobile rig and err on the conservative side limiting available power to the continuous rating. Even with that if you're playing sine waves it is possible to melt a voicecoil without ever seeing a clip light.
