Question about SVS PB12

[sean_thao]

If you were to run this sub through the Yamaha RX-V1700 reciever..would it run ok????or would i need to buy a separate amp to power the sub??? i know its a high end sub but was just wondering....

The PB-12 is a powered subwoofer meaning it has its own internal amp. So you wouldn't need anything special to run it. Just run a coax cable from your receivers preout to the sub and you are good to go.

thanks...do you know why these subs are so heavy by the way?? because i was comparing this sub to a klipsch and its also a 12 inch but is waying at like 45 pounds....

 

[avaserfi]

The subs are so heavy for a few reasons. They use very substantial drivers, especially compared to most other subwoofer companies. Also, they probably have a bit more bracing internally compared to others.

SVS makes a great sub rest assured if you get something from them you won't regret it except for the fact that you might want another .

My guess...heavier woofer assembly and/or heavier box. The box is likely solidly built with a good internal support structure, as well as having good insulation.

EDIT: Was answering this at the same time as Andrew. Sorry for the repetition.

as well as having good insulation.

Cause that good insulation is so much heavier than the bad stuff.

Just razzin ya.

Thats it, you just need to quit stalking me!

I have mace Adam and I might even know how to use it. Point the hole at my face, right?

It's pure physics....

For a sub to go really low and perform well...... size and weight matter.

Not to be too simplistic, but in general........bigger heavier subs are built better, offer more performance, and cost more.

............but not always, as you have found.

Hee, hee. I was thinking about my B&W sub with a good deal of thick insulation version some Radio Shack speakers that I have with, well, paper thin almost-lighter-than-air insulation.

Would you be willing to switch to pepper spray? While still enormously painful, it kinda reminds me of salsa.

And, ya, that hole is for sighting things in, so look down it before you spray.

LOL, ain't that the truth?

I have that sub in the Plus line.... and it indeed plays good, deep, and powerful in the right room... These guys are correct, all things added up here - Amp, driver, and quality heavy duty construction, means your getting a good product, with capabilities many subs don't have....

My next sub (DIY) will more then likely be one of the Heavy Weight Champions of the world, with real hardwood, bracing, huge 15" driver and Granite Top... Im extimating it weighing no less then 300 lbs...

I have a question is hardwood a good alternative? Most people would recommend high grade plywood instead. Most natural wood will react to humidity and moisture and plywood and MDF are more resistant.

I do not have problems with humidity or moisture in my house....

Im not concerned about it....

I, for one, cannot wait to see pictures of that when you get it done! I'll bet that thing is going to be gorgeous.

Oh, yeah...300 lbs?!?

I agree 100%!!!

I didn't find much insulation in my Plus. Just like a handful that somebody grabbed and stuck on the inside wall of the cabinet.

How much and what type of insulation is supposed to be in a PB12-Plus, anyway?

believe me those are a lot compared to other subwoofers which use a 3/4" thick batting.

I'll have to look again next time I open up my Plus, but I don't recall the level of insulation in those pics being in mine.

Would it be worthwhile to open it up and line the sides with OC 703?

we're gonna have to wait for the DIY guys or wmax to chip in.

pros:
less resonance
possible more volume due to more absorption?

cons:
possible less volume due to more OC703?
