Oh man! That sucks. Were you present when the lightning struck? Where did it hit? The welder too!? I'd be so sad if that happened to me. The only good part is tech advances so fast you have the option of updating lineup with the latest tech or going with similar spec'd products at lower prices.

In my living room - hit just outside the house!  Never seen a room light up like that in my life.  Tripped one breaker, but was enough to take out anything sensitive.  Not sure how it got the welder through the 220 line, but HDMI ports are no surprise.  They are a pretty terrible design in how sensitive they are to voltage spikes, even very minor ones.

I actually talked to my insurance agent about it.  Long story short, I got f*cked on a roof claim when I bought my house, and it wasn't worth risking losing my homeowners insurance over what would have been about a $3k delta after the deductible.  Agree totally on the power conditioner - have one of the APC's on my wish list.

You can also get whole house surge suppressors.  I'm looking into an Eaton unit, but I don't have time to look up the p/n right now.

Not to toot my own horn, but I have a MacPherson 18" Ported sub and 2 IS12x loudspeakers running off of a crown amp in my garage. :wave:

That's a good setup for a garage. Must be nice to work in there. Beer, music, car, maybe toss in a woman or two to finish off the perfect ambiance.

That must have been quite the experience. My balls would probably have climbed up into my stomach out of fear.

A power conditioner for the whole house, that must be pretty expensive. I have a monster power conditioner right now. I'd like to run the powered subs on a separate circuit and thinking about getting another conditioner just for them. Waiting for my ground isolation transformers to arrive and see if they resolve the ground loop hum when I connect the power cable to an outlet separate from the receiver. Afterwards I'll ponder the idea of another power conditioner.

The RCA Y-adapters and the blue jeans subwoofer isolation transformer solved my issues. On to the tuning. Hopefully I can find a balance I can enjoy. I normally shoot for clarity in dialogue and a fairly heavy hitting LFE.

Does your receiver have MCACC or similar?  That always seems to get me surprisingly close!

Yup, running MCCAC and manually tuning to taste afterwards. All I know right now is these subs are causing me a ton of anxiety. Every time an AV clip with a hard hitting LFE plays my house shakes and I hear a deep rumble. I get scared and excited. Similar to the sensation you get on a roller coaster as it slowly makes it's way to the top and you anxiously wait for the drop. I hate that feeling! but the fact I feel that way from these subwoofers is just awesome. Its a love hate relationship, lol.

I guarantee that wouldn't go over well with my wife.  LOL

When I built my house I incorporated a sub-woofer nook in the great room to keep it out of sight.
Though mine is only a little ported 10" unit, I placed a 2" thick pad of closed-cell foam on the floor, with another panel of MDF on top of that, with the sub on top of that.
It almost completely eliminates the vibrations transferring into the floor structure.
Together with insulated interior walls and sound-absorbing bedroom doors, it works pretty well to keep the bedrooms quiet.

Of course, I'm not really an audiophile, and keeping the equipment discreet was my major goal, but I do enjoy having a decent surround system for TV and movies.

That will definitely help minimize energy transfer to the room especially if its a raised floor. Acoustic foam in the corners would also help. I'd like to build a nook for these subwoofers with some sort of rear access. That would be awesome it would just take a lot of time and energy.

It's been some time since I last updated the cables I ordered a bunch of HDMI cables and appropriate length mono rca cables. Thinking about getting a pair of power conditioners. Currently have this in mind, CyberPower CP825AVRLCD. If you guys have any recommendations that are cheaper or better I'm all ears.

I've never seen subs that big!  My system is 100% Klipsch speakers with a Denon AVR-X6200W receiver and a single 12" self powered Klipsch sub.  9.1 surround and is all that I will ever need.
