Have a couple of questions about SVS subs.

Luis Cruz · 09-14-2003, 11:01 PM

Hey all,

I have been thinking about changing my sub for a long time now. I've been dreaming of getting an SVS sub for maybe a year and am now trying to get a job while in school to get one, hopefully be able to get one in a couple of months. So I have a few questions for you HT dudes out there. Alright. I currently have an Energy e:XL 12 (I think that's the model) and I have been pretty happy with it minus some things I don't like about it. Firstly it has a great look and it sounds nice too. But the port noise bugs the heck out of me. Now the port noise only has been apparent now that my family decided to switch the furniture around. Ok...well, on to the questions about SVS.

The living room we have now is not all that big, but we are moving and I am pretty sure the house we do pick will have a big living room. Our current living room is about 12ft by 13ft. Not that big at all but when we move the living room will probably be around 20ft by 20 ft or a bit bigger. So here are my questions:

1) Have any of you SVS-owner's out there experienced any sort or form of port noise? If so how bad?

2) How would an SVS compare to my current Energy Sub? SVS models like PB1-ISD, 20-39pci or pc+, or PB2-ISD.

3) How would a PB2-ISD compare to dual PB1-ISD's or dual 20-39pci's?

I think that is it for now. The reason I asked question #3 is that I have been wondering if dual PB1-ISD's or dual 20-39pci's would be similar or better to a PB2-ISD. Because if the former is similar in all aspects to a PB2-ISD it would benefit me because I would be able to buy 1 sub now and then when we move another sub to go with it. But if the PB2-ISD is better then I'll probably just have to save more cash. But that's it for now. I can't wait to see your replies and I thank all of you ahead of time for helping a crazy college kid out. Thanks and God Bless.

Is there a reason that the PB2-Plus is not in your list of options?

Luis Cruz · 09-14-2003, 11:52 PM

Well, I thought about the PB2-Plus but I read on some of the other post that the PB2-ISD and PB2-Plus were close in performance. So instead of spending an extra 350 bucks on the PB2-Plus I could put that toward upgrading my reciever.

Luis,

Glad to see another "305" member. If you are looking to demo an SVS to base your decision on and answer your questions, shoot me an e-mail. I'm in the area and would be more than willing to demo mine for you. To answer your previous question, I have never experienced any port noise from my 20-39 PC+ and my current home theater room is just slightly bigger than your current room. Obviously mine is not the box design that you mentioned thinking about but if the performance of the PC+ impresses you, and I can't believe that it wouldn't, then I'm sure you will be happy with any of the PB2-x configurations.

Luis,

Sounds like a good decision. Thanks for answering my question. Since the "ISD" is still on pre-order, I'm sure we'll hear more reports on them once they get into the homes and theaters of more users out there. Like you, my eye focused on the ISD -- (2) 12" woofers and 600 watts (conservatively rated) of amplifier power is nothing to sneeze at. Plus, being able to plug ports to get deeper bass just ices the cake.

Now, I just need $950 ...

Hey a fellow "Miamian." lol. Thanks for the reply Pete. See, what I am worried about is whether or not one sub will fill up a big room, since the fam will be moving in the near future. I know any SVS will fill our current living room with ease, but how will it sound in a bigger room. If a PC+ could fill up a big room with hard hitting, deep base then I'll just opt for that as that will allow me to save some cash...since it's hard to save money while in school.

I am glad to hear you haven't experienced port noise. I keep talking about port noise and my sub and I don't think I should if I ever want to put it up for sale on the Hardware For Sale/Trade forum. lol. But it's not that bad, only sometimes when there is some really low content on a dvd. By the way, how big is the room you have your SVS in Pete?

I hear ya! It's gonna take me a couple of months to save up the cash for my sub upgrade, but if I can sell my current sub then that will ease the pain a bit.

Regarding the PB2-ISD vs. the 20-39PC+:

A PB2-ISD will have the edge over a 20-39PC+ when both are set to 20hz mode. From about 16-25hz it would be close, but the PB2-ISD will edge out the PC+. Over 25hz and the advantage grows to the 3-4 dB range. So if you can live with the larger PB2-ISD enclosure, it represents a better performance value over the PC+.

Regarding the relative merits of the PB2-ISD vs. PB2+ vs. PB2 Ultra:

All three will have the same extension capabilities, but the PB2+ will have an edge in clean output capabilities, and the PB2 Ultra will take that another step further.

Going from the PB2-ISD to the PB2+ will give you a 2-4 dB jump. Going from the PB2+ to the PB2 Ultra will give you another 1-2 dB jump. So going from the PB2-ISD to the PB2-Ultra will give you a jump in the 3-6 dB range.

All of the SV subwoofers are designed to produce any input signal (music or film) as accurately as possible. The PB2+ and PB2-ISD will sound identical until the PB2-ISD reaches its output limits. At that point, the PB2+ will still be able to play another 2-3 dB louder without straining.

The above comparison stats were largely quoted from a Tom Vodhanel post in another forum. Hope it helps you make the decision.

Regards,

Ed

I have a 20-39 pc+ in a 15x25 room. That sub fills the room (and my house) at 1/4 gain. IMHO, I think either sub will be more than adequate for your room.

Luis Cruz · 09-15-2003, 02:32 PM

Thanks for the replies guys. If a single 20-39 will fill a big room, which I think is the case considering what people have said here I might go that route when I have the money. But then again, for about 100 bucks more the PB2-ISD does look tempting. I guess I might just have to save up more money. Now I haven't gotten any responses about how an SVS would compare to my Energy Sub? If anyone out there has ever compared the two how were the results?
