Default Subwoofer time... rounding out the new system

Gentlemen,

Upon finishing the bulk of my install, all that remains to be selected is the subwoofer. At first I wanted to go with the driver's side glove box stealth install, but that really isn't cost effective in relation to the sound quality I would get ($310 for a box... come on). So I think I am going with the single 10" under strut box. Here is my set up:

Alpine MRV-F345; the 3rd and 4th channels are bridged, producing 300W for a sub.

Now, I want a sub that hits tight and deep, because I listen to house/progressive music. It must produce clean sound and be civil around town, and and be able to hit deep when I decide to turn it up. I am not looking for the low, deep rumbling that rattles your license plate you get when you listen to hip hop, but rather the deep punchy sound that you feel hitting in your chest. It has to keep up with the music.

So for those of you who listen to house/trance/progressive, what kind of sub do you think best suites my requirements?

Edit: I am looking to spend around $150-$200.

trust me.. this sub is worth the price.. it out performs that JL posted above.. you are getting $600 performance at this price

IDQ or Elemental Designs 10Ov.2 ($155) but I'm not sure how it would be with 300 watts

+1 on the eD 11ov.2, but you should take advantage of its power handling.

Of course I might be biased

I wanted to go with an IDQ sub but at the time, no one had them in stock. I don't regret my decision though.

doug, streetOC192: will 300W be enough to run the subs you suggested?

I'm running 320 into mine right now (4 Ohms) and it sounds fantastic.

On a side note, I am planning on a new understrut box and subwoofer, so I will be looking to sell my box/sub combo if interested in a 1year old lightly used setup.

Tight and deep, no rumble = sealed box design.

I'd recommend a subwoofer who's Thiel-Small parameters give you a slightly higher than normal Qtc - something around 1.3 to 1.50. You'll sacrifice a couple of hertz worth of response on the bottom end but you'll get a bunch of acoustical gain in the mid to high bass. You might want to run your crossover's a bit higher than you otherwise would if you go with this higher Qtc. If you're not willing to do that then lower the Qtc down to 1.0 to 1.2 and you'll get a bit deeper with less gain.

ETA: if you're not going to bother with the science just get one that looks pretty.

I talked to Bing about it for a while. He suggested either IDQ or 11Ov.2... problem was, I think they were phasing out the v2 of IDQ and no one had them for sale lol

Soooo... with the under strut box from ZEnclosures, which subs fit this description? Not asking because I am too lazy to search, but because I have no idea what you just said

Not disagreeing with you or science, but the Diamond D610 has a qtc of .625. I have it crossed over at 80Hz. It sounds pretty deep and hits hard to me in the sealed under strut box. And I may have listened to 1 or 2 subs in my time

The Diamond has a Qtc of 0.625 in the volume of box you installed it in ... the box and speaker combined create the Qtc. That's a very good match actually with .7 considered "perfect" - at least perfectly flattest. At 0.625 you've lost a tiny bit of gain for a tiny bit of deeper response but likely not very noticeable and I have no doubt a very tight/deep sounding system likely better than most.

Too many people put a subwoofer into a random sized box because of the size of the magnet, extreme cost, looks, or it's what sounds good in my friend's car (in a different sized box!). For three years I've been pushing the science and sometimes people get it.



I went into my subwoofer purchase backwards buying the box first as there aren't that many choices. I love the Zenclosure box and found a pair of 10" speakers that fit my budget and gave me a Qtc of .8 something.

Music is very subjective so I always tell people to audition the speakers with their own ears and music. Back when I was still in the business we were one of the first car stereo places with an A-B/X switcher. When I wasn't installing system I had the run of the thing and tried out every speaker in the shop listening to the differences in each one - and the differences were big between each manufacture and even within their lines (to a lessor extent). Even knowing what each speaker sounded like I couldn't guess what a person's taste in music was.

Personally I like a tight sound where the transients are breath taking and the bass is deep and controlled with the midrange and tweeters a bit forward of where I've found most people like/most speakers provide. The OP did a pretty good job of describing his bass preference and therefore I recommended putting his ears on a speaker that's going to have a bit higher Qtc - at least that's a good place to start.
