LOL. No way, Jim. I didn’t realise you already had the other sub when I made my first post on this subject. Remember you are talking to the guy who is not using his HT at all right now, because of my Submersive amp failure. I'd rather not use the HT at all than use it with just one sub!
New HP+ amp master/slave is being shipped to me Monday.... 4000 watts of woofage...
Mains = 350w x2
Sub 1 = 250w
Sub 2 = 100w
I think your wattage Rabbit hole is much deeper than mine
FYI, all the wattage disparity works out in my case because of efficiency and attenuation differences. Sub 1 is more efficient than my mains. Sub 2 is attenuated compared to Sub 1.
I am sure that 4,000 watts of woofage is overkill here, in my small room. Headroom is one thing, but headroom is another ;) But that's the amp Mark offers these days with the SubMs. If you have one HP+ in each sub, then it's 2,400 watts per sub. But if you use the master/slave arrangement (which is massively less costly) then the combined woofers drop to a 2 ohm load, so the amp delivers 4000 watts, but has to power two subs (4 x 15 inch drivers).
On the rest of the (7) speakers I have a combined 1,650 watts.
