Favorite Sub? (Which is better?)

[icu400]

Well, it has been a few weeks now with my sony 10's, and I like them. But I am looking for something a bit better. I listen to pretty much everything from rap, to classic rock, and even some willy nelson ever so often So basicaly I am looking for something to add a bit more bang but with a focus on clarity. My amp is a sony mono amp that puts out about 250 rms. Its the newest sony amp so I don't think it is overestimated much at all. So as far as power goes, I am trying to keep it between 200 and 300 watts rms.

So, here are my prime suspects:

Rockford Fosgate Stage 2 10" (These have a low mount depth but only 1 voice coil)

Alpine Type R (DVC, but sort of deep)

JL Audio w3v2 (DVC, pretty shallow, most expensive)

Any others I should check out?

The new subs will be put into 2 stealthboxes that I am going to start work on within a few weeks. I want to decide what I am going to upgrade to before then, if I will upgrade at all, because the box will need to be tailored to that sub. They have to be 10's because thats all I have room for (and I don't like 8's).

I realize that this is something of an opinion request, but if yall can tell me any practical knowledge about which works better, is more clear, that sort of thing, I would appreciate it.

Peace

you should look at the image dynamics ID or the id Q if you have that kinda money. the id goes for around 130 and the Q goes for like 180ish depending on where you go....these subs sound awsome and have great sound quality. definitly will stomp your sony's .....you could always spring for a single id max....but then you wouldnt have enough power to run it.

Well since you asked for "opinions", I have one. The Boston Accoustics ProSeries subs are very, very clean hitting subs. I am not sure if they are the cleanest hitting subs, but they hold there own. A little pricey, but worth there money in the end. Some of these guys that go around to the audio shows are probably more knowledgeable than myself, but I would bet that the Boston's are in the top 5 of subs as far as quality of sound. As far as JL's go, overpriced for what you get. Seem to be the hottest sub going, but IMHO Boston's sound better than JL's when compared apples to apples.

Best of luck to ya on your selection. Take lots of pics and share them with all of us on your install. Some subs sound better ported than others, so make sure you know what you want to build before buying the sub.

And in my opinion, I favor anything JL Audio. But then again, I perfer bass on the lower end of the scale (<60hz), which JL supplies a whole heap of.

You are going to get about 3 million "opinions" from this thread, which are really not going to do much but confuse you. You have a list of good quality subs there, so at this point its all about what YOU like. Check the specs on each one of those and compare. For example, if you want a a sub that's an spl monster look for one with a high xmax and a high RMS power capability. If you want a sub that hits low, look for a low FS (resonant frequency). If you want a sub that doesnt require a lot of power, look for one with a high SPL@ 1w/1m(sensitivity rating). There are many factors when comparing subwoofers, but the best advice that i can give is compare specs, then go listen. Good luck.

IDQs and JLs are very nice subs, but go listen for yourself. If I were you I would get rid of the Sony Amp as well. Maybe try Crossfire, JL, Alpine, JBL, Tru, Phoenix Gold to name a few.

 

[icu400]

The amp is something that I might upgrade later, but for now it does what I need it to do with a low THD rating. I could spend the same price for a new amp as I would for 2 new JL subs, so that is a tad lower on my list of possible upgrades.

Thank you for your post Fhant, that is sort of what I was looking for as far as what those sort of specs mean and what to look for. Thanks

Anytime man. If you have any other questions, feel free to pm me here and Ill give you my yahoo id.

what do "qts" "qms" and "qes" represent?

If you're looking for something that fits in a very small box, and is supposed to have very good sound quality, you might want to check out the eD 11Kv2. Right now they have a pre order going on for $80 per sub (scheduled to start shipping sub the first part of July). They are calling out a power handling range of 150 to 500 watts RMS and a recomended sealed box volume of 0.4 to 0.6 cubic feet. Sounds like it will be a great sub, but not to many people have heard them yet since they haven't went to production with them yet. Plus you get a 3 year transferable warranty with them. Here's a link to them if you want to check them out:

Wow, thanks dude, that should help a bit. (One of the reasons I was looking for opinions was that when I was looking at the specs I just saw a screen of numbers, lol)

Geezus! Have you watched that excursion video?? That is unreal!

 

[icu400]

Dear lord! Now THAT is whack! Those make my sony's look like they are freakin standing still.

 

[Mountaineer97TM]

I think and a lot of other people thing KICKER SUBS are the best. I have not met another sub that is better then mine.

 

[icu400]

To each his own. The kickers I have heard were a lot more bang than they were clear, but that could have just been the model I heard or the way the guy had it set up. At this point I am just running some numbers and in a week or two I will go visit a few shops.
