Polk Audio SR104-DVC

So, I must have looked at this thing 100 times in a month before going ahead and ordering it. I have a custom fiberglass enclosure that's a little more than 1 cubic ft and I'm using the Polk PA1100.5 5-channel amp powering my whole system. My original sub was just a plain Jane 4 ohm single VC Kicker and it sounded pretty good. I was really just shopping for a dual voice coil replacement so that I could run my amp down to 2 ohms. I went back an forth and eventually said to heck with it and spent the extra money for this sub mostly based on the reviews I read on Sonic and elsewhere. IT'S ALL TRUE! This thing is amazing! It does have a much higher SPL than the Kicker I replaced, but really stands out is the sound quality. As with the other reviews on here, the kick drums sound like kick drums (imagine that). If you're serious about audio and want your sub to reproduce music and not just a bass sound, but this sub. Follow the directions, however. They state that a break in period of 50 hours is required before it will hit it's stride and it is true. The surround on this thing was so stiff that you could hardly even move the cone with your hand. I noticed an improvement in SQ just after the first hour. Given the large volume displacement of the RIDICULOUSLY sized basket on this thing I figure that it's sitting in about .8 cubic ft of airspace which is about .16 more than recommended, but it sounds AWESOME! The quickness of response with this thing really stand out and it handles overlapping freqs with ease!

PROS - Fit/finish, SQ, value, looks, quality (it's worth way more than this price tag!). This may be the most musical sub I have ever heard, period!

CONS - it is heavy! Make sure you have a sturdy enclosure and bolt it to the car for the best result. If you're a teen aged kid with a box sliding around in your trunk, buy the cheap Kicker or equivalent. This sub deserves a well balanced system in support of it. Also, I wouldn't mount it to your baffle with Dry Wall screws, they won;t stand a chance. Get yourself some t-nuts so that you can really tighten it down snug!

I totally recommend this sub to anyone. It is well worth twice this price! Don't be cheap, just buy it, but don;t disrespect it by only playing rap or hip-hop through it. This thing really deserves to be listened to.

These subs have everything a 3000 dollar sub possess. I know because I own a pair.

I have two of these Polk Audio SR104-DVC , i have a Precision Power DCX 500.2 amp pushing both of these and they do the job and then some :) Any one who planes to run Polk all the way around these SR104-DVC are closers end of story, my head unit is a Alpine 9887 with lots of options for tuning, I have another Precision Power Amp DCX 300.4 pushing the component Polk Audio db5251, along with Polk Audio 6x9's db691. I have one 2 Farad cap for the 4 channel that keep the power stable one the four speakers.
I plan to upgrade all speakers to SR from Polk but at the costs it hard to get a handle. I love this site www.sonicelectronix.com I wish I new about it sooner I cane across it one day looking for these bad boys SR104-DVC.
The SR104-DVC are not cheap but worth every penny.
Ps you do have to brake these in a little bit, if you dont you will smell the sub getting hot.

I think this is a Very Amazing that is deep and clear and so do my friends that have 1) a 12" Type R and 2) a 15" kicker. I put 800 watts rms to it and wish I had 1000-1200 rms going to it. It doesn't skip any notes and hits a few more lower ones. I have it in a custom ported box set to spec. If you do get one of these it doesn't rock the block but the car next to you can definitely hear it.

The Polk 10" SR sub is outstanding, well worth the money.
Its one of the cleanest tightest subs I have ever heard. not great where limited space is a concern but I have it in a 1 cu. foot sealed box with a 500W Kenwood amp an its amazing.
