Obtaining a good punch!! - Blu-ray Forum

nothing.sound · 01-02-2009, 06:40 PM

Ok this is kind of hard to explain. Most of you are going to think I am crazy!

How does everyone's subwoofers sound?? Do they have a good kick or punch to them. Or are they just boomy and bassy.

I've read so much stuff on here over the past year about calibrating audio and room acoustics and what not. But I can't seem to get my sub to where I like it. I'll attach the specs of it and a pic. My crossover is set to 60 hz and it's set so that the receiver handles it and therfore the phase is not important. I had an old 5.1 jvc HTIB and it actually sounded really good. I remember watching some movie (i think it was once upon a time in mexico) and antonio baderas was firing a shotgun and it just sounded so amazing. Now I have this crazy expensive sytem but just can't get that punch.

I hope some of you kind of know what I'm talking about. I can't wait until I build my theatre in the basement so I can perfect my set-up.

New sub?

Dude, he's got a nice energy system. Don't become the guy that has one answer for every question (get an eD A2-300).

I would guess that you need to experiment with placement and calibration. If you want more punch from your sub, why not up the crossover point a bit? That'll give more of the load to your sub. Maybe try an 80hz crossover point? Not much difference, I know.

Try corner placement, changing the volume, running calibration again, changing the phase. That sub has a 21hz extension.

I think often the problem is that since it is too hard to often place the sub in the ideal spot to make it sound good everywhere in the room it is best to get more than one sub. I used to have just one and now have two and am much happier not at just the impact but more that the sound is the same everywhere and it is hard to tell where it is comming from.

if i get a second sub, do i have to get an amp???

gearyt · 01-02-2009, 08:01 PM

most subs are "powered" and have their own built in amp

I agree with the idea to use an 80 Hz xover and maybe even pump up the sub even beyond the recommended level. Whatever works for you. Also note that some soundtracks do not showcase the LFE channel particularly well. So be sure to test it out using the right material.

I feel like I just passed a pop quiz or something.

No, I know. I was joking.

I know it didn't come off that way though.

Corner placement, double bass, upping the crossover, turning the sub up or getting another would definitely help.

gearyt · 01-02-2009, 09:44 PM

remember it is also the room size, configuration..amount of air pushing arround

yellowblanket · 01-02-2009, 09:55 PM

lol get a bass shaker! i watches fight club with the bass shaker on and it was exelent.

ps: no it doesn't feel like someone punch me in the butt lol

If you want your subwoofer to PUNCH, buy a pair of boxing gloves for your subwoofer.

If you want your subwoofer to sound nice and blend with the rest of your system, you have to be patient and experiment. Subwoofers are like mis-behaving children. You have to understand them and play with them. Calibration and their position in the room are as important as the quality of the sub. If you haven't already done so, read A Guide to Subwoofers and A Guide to Subwoofers (Part II): Standing Waves & Room Modes. Hopefully, these two threads will help you get the punch out of your subwoofer.

How large is your room? I would also mess with the Hz on the sub. I just learned a few things about the settings on the receiver and subs. I learned the hardway, my number's are reverse on my sub.

If you want to do some quick testing of your sub, use your PS3 web browser and goto this website and try out a few of the link. Make sure to turn your volume down before testing

GIVE YOUR SUBWOOFER A WORK-OUT

There are a few links you can really use to get the nice smooth bass you want/need.

Could be the enclosure. Alot of times boomy sounds come from subs with enclosures to small or ports that aren't really optimized for a wide range of sounds. Either one could be causing a certain freq. range to stand out more than others. It's what you hear on the regular high-school student's subwoofer in his truck. All the bass will sound the same because the specific frequency is getting a extra boost in it's paticular sound. E.G. a note that normally would sound very low (20hz range) with lighter stuff going on in a higher range will all sound like it's in the 40-60hz range.

But with a downfiring port system like the one on your sub, I'd imagine the sound is the air push forcefully into your floor. If it's on a hard surface you might want to move it onto a softer one. Try moving it out of a corner if thats were it sounds boomy. But if it isn't in a corner, you will be a punchier sound from one.
