So like actually how many amp service will the electrical company supply a residential service? Will they just give you whatever you ask / pay for or is there a limit? haha. Maybe they'll just charge you industrial rates

I assumed 200amp was the largest service for a residential service

You can definitely get 2-200 amp service as many very large custom homes will get that. I imagine you just pay for each 200 amp line to your house, and they will do whatever you ask. Unless there is some kind of law against residential customers having too much power available for some reason.

edit: Looks like it's about $3000 to go from 400 amp to 600 amp service that's not too bad! lol

Kipnis had two 800 amp transformers installed for his house. He said his electric bill was north of $1200 per month.

You can get a 600 amp service if you are willing to pay for it lol. I've seen a few with 2 x 200s that my brother worked on. It was literally 200a panel on each side of the house.

I work for a genset sales company and do a lot of residential installations. We regularly see custom homes with 300-400A services and every once in a while you might see a 600A service, but not very common.

Back in '92 I installed my own 200 amp panel , the mast, et al, inspected etc.

and then Edison came out and did the"touch" as they called it that.

3 isolated ground 20 amp lines for the HT.

Hi there.

In the german forum beisa m men . de they actually did a group buy from that chinese company. The outcome was the so called "Luftverschieber" (Air-Displacer).

I had 2 of these subs at home but never built anything with them. Superior build quality, cheap (arround 120 per unit--> INCLUDING SHIPPING), great TSP for output below 60hz in a sealed box.

Oh, not to forget: They are the manufacturer of the Stereo-Integrity Subwoofers.

Regards,
Herb

You mean this?
  • Spends $6,000,000
  • $2 drywall

  • Spends $6,000,000.
  • Forgets to install air conditioning.

  • Spends $6,000,000.
  • Forgets in-floor cable management

  • Spends $6,000,000.
  • Maybe some more disco lights and disco balls will fix it

  • Claims flat to 1Hz
  • Uses high-tuned ported subwoofers with PA drivers

Did I miss anything?

Heck yeah.

When I first moved we threw a house party. It was in the middle of winter.
I had the heater off, and we had to open the doors every 10 minutes because the air temp was approaching deadly temperatures.

A combination of 10-15 people dancing in a room with 50kW and in an R-40 insulated hermetically-sealed room-in-room.

In the summer my roof can be 115 degrees, but inside it is room-temp, without any air conditioning on.
In the winter, I can heat my room with just a 6-inch heater or my amplifiers at full-tilt for 8 hours. (and that's well below freezing.)

I'd run my HTPC+ power conditioner 24/7/365, which is 200w idle, and that heated the room +30 degrees.
Which is handy in the winter but a pain in the summer.

I could only imagine 90 vacuum tubes (or whatever his is running there.)
Good thing he has like 16ft walls. Otherwise it would be death hot in there...
especially when bumping loud for a few hours with the projector on, and all that array of 150w disco lights...

I could totally see a power bill of $1200 a month if he left it on.

Thanks diving in on this Chinese 24" woofer.

Anyone know if Mach 5 is still planning on bringing a 24" to market? I inquired on status through their FB page several weeks ago, but no response.

I re-re asked them for the T/S specs.

I'm guessing they don't know, or don't care, or both!

I have to ask this since I cannot figure out the answer myself. Big drivers are cool and all that, but what is actually stoping manufacturers from producing a smaller driver with excursion massive enough to match a performance of much bigger driver:. eg. 18" that would perform identically as HS24 by SI?

Probably cost. The Rockford that Ricci uses is a very robust 19 inch and costs $2500 and still can not produce the same spl as the SI 24 which is much less in price. Upper bass is on par with each other.

Cost, sound quality, and efficiency are a trade off of a ultra high excursion smaller cone driver. More excursion equals more distortion. Then you need more expensive components( voice coils and increased motor strength) for proper heat dissipation and cone control.... that drives the cost up. Also, more amplification is required to get that driver to xmax and that also contributes to more cost in the end. Imo you are always better off to go with a larger cone when possible. That is why in Pro Audio, multiple lower xmax 18 and 21" drivers with lightweight components are used because they can play hours on end at extreme levels without smoking a coil.

Also physical limitations of the size of VC, spider diameter, surround size, and only 18" of basket to hold it all. A spider big enough to handle say 75mm of xmax with a 4" VC would need to be maybe 18" in diameter. So the basket needs to be bigger than 18". Hypothetical numbers of course.

It would be very non-linear too.
