Supercube 2 replacement

Will the SVS PC12-NSD be a good replacement for a DefTech Supercube 2? My wife has given me the OK to get a replacement and the PC12 ergonomics are perfect for where I want to put it. I'm just not sure if it will sound better.

Thanks

With svs having a no hassle return. order a couple different ones and send the ones you dont want back. Im sure that it will out do the def tech.

I have sc8000 (not sure if it's the replacement for the 2). 11" driver etc.
I have the pc12 plus. The plus is a much better sub all around. Output, sound quality, extension and the like.

That said having recently added the sc into the mix has made a noticeable improvement.

The pc12 will extend deeper and higher. Should sound better and have about the same output above 20-25hz.

The finance department put the Kibosh on the PC 12 Plus so I ordered the PC12 NSD. Should receive it sometime next week.

Congrats. I'm sure you'll like it.
Are you keeping the deftech?
Dual subs really do make a difference even if they are quite different.

I would love to but probably not. The room is fairly small and I only have one corner to place a sub and I don't think putting them side by side will do well. The wife probably will not go for it anyway but before I sell it I will try it out.

Free returns if I don't like it not much to lose and I hear great things about SVS.

SVS is awesome, I have bought many items from them, including a pb12-nsd. These are great subs, I think you will be very happy, congrats on the purchase!

Got it today. Initial thoughts is it gets lower than the supercube 2. I pretty much did a plug and play no tweaking yet but it does not seem to hit as hard as the SC2. I'm guessing that the higher bass frequencies of the sc2 are more prominent. I will run the calibration in the receiver and tweak some more.

The SC 2 and SC4000 are similar models. You can see the measurements for the 4000 here

http://www.soundandvision.com/conten...-labs-measures

http://www.soundandvision.com/conten...-speaker-and-1


Basically the SC2/4000 does well in the mid and upper bass(40hz and up) but they start to really struggle <35hz and by 30hz they look to have a SHARP rolloff.

A sub like the svs is going to provide much deeper extension and output in the 15-35hz range. This is often interpreted as "less punch" because RELATIVE to the upper bass output....the svs will maintain a good sense of linearity.

When you say "hit as hard" is this will music demos mostly? I'm thinking if you popped in say...War of the Worlds....you might *feel* differently..

Maybe hit hard is the wrong word "punch" is more accurate. As you stated it is the upper bass range that I am missing. After running calibration it does sound better but I am not sure I am satisfied. The PC12 PLUS has a +/-3db point all the way to 250Hz where the NSD is at 130Hz. I think I may have to return this one and bite the bullet and get the Plus.

I'm not sure if that will really help. I'm assuming you are using a typical 5.1 system with an AVR and 5 speakers that you have set to 80hz? If so, the upper frequency extension of 130hz should be plenty.

If you have some way of EQing the bass signal you can try bumping up the 50-80hz range a bit.

Be sure you have the crossover on the sub set to its highest setting/bypassed. Also, experiment with the sub distance setting and/or phase setting.

The SC models fall off pretty fast after about 90-100hz. They have a pronounced "hump" in the mid bass range say 40-70hz or thereabouts.

The PC12 is flat throughout as are most good subs so you don't notice the mid bass as much. One of the benefits of the Plus and Ultra is the three band PEQ that allows you to put some of the "hump" back in if that's what you like.

Yes. I spoke with SVS and that is more or less what they stated. What I am missing in the PC12-NSD is somewhere in the range of 60-80Hz. The PLUS (and Ultra) performs better in that range than the NSD. I ordered the Plus this morning (wait till the wife sees the CC charge) and will return the NSD.

The pc12+ is in a different league vs the pc12-nsd, especially with regards to music playback, at 30hz and up its 6-10 db more output

The pc12nsd should have more output capability than the super2/4000 even in the mid and upper bass.(at least up to 80hz). So I don't think it is a question of having more headroom. More likely, you are used the shape of the DT frequency response.

Wow 128dB! Yeah couldn't listen to that for long either.

As Tom stated you are probably use to hearing a large hump in the frequency response and if that is the case the max output of any flat response subwoofer wont change that but also not all subs react the same in the same spot in a room. Spending a little money on a spl meter or mic for REW will give you a better idea of what you're hearing

The frequency range and output are much better. The low end is amazing, watch Oblivion around the 19:00 mark when the rope breaks... Impressive! Battle Los Angeles never sounded so good. Still making some minor adjustments but so far very impressed.

Only down side it is big! Doesn't take much floor space but it is nearly as tall as my 5' wife....
At least she is not complaining about the size only about the walls shaking...
