subwoofers

[Rock&Roll Ninja]

can we put subwoofers one on top of the other? (curious for those with limited space; and placement problems)

Depends on the subs. I can't imagine trying to stack SVS tubes, but many box subs can be stacked easily (assuming you aren't blocking woofers or ports), AV123's Rocket subwoofers are usually shown in a stacked array.

Thank you both for the information. I had not considered the H100 or E250p. I'll have to dig into those a bit. I like the little I've read about the H100, but I'm not sure I want to have "placement" issues. Realizing that generally any sub will sound better if optimally placed, will the H100 still sound decent if it's simply placed in a front or rear corner of the room or will a slightly sub-optimal placement (pardon the punn ) totally wreck the subs performance?

Trust me 90% of the subs, including the ones you are looking at will need placement. The easiest for placement I have found is the E250p. But with this sub you will not hit the sub 23hz range. The H100 as well as the others you are looking at will need placement, but they will go lower. And for HT (movies) this may be a thing you want. Just PM me, and I will give you a phone number to call me on the weekend, if you would like...

I have spoken with Brian on a few occasions. He is very knowledgable on budget equipment that works well. He has heard a few systems in the 10,000+ range. But he does like to find what is best for a budget. I beleive he strives at looking at budget systems, keep it up Brian. I have taken his recommendation, and I could not be happier. Thanks Brian!! He will not look to spend 1,000 on one piece of equipment. He from what I have found will guide you in the right direction.

.....TOTAL agreement....have talked to Brian many times....the boy's a talker, haha.....

Actually, much of the detail I hear was not in the infrasonic range, but 30hz-50hz (my sub is crossed over at 60hz). I think that the HGS-12x would still lack some of the detail that I am hearing. I think it would also be lacking in the very low end extension, i.e. below 20hz. The output difference was not even close, (HGS-10 vs. Ultra) which I was expecting. However, it was much more than I thought it would be. I think the HGS-12X would keep up a little better, but still be behind. The guys at SVS compare the PB12-Ultra to the HGS-18, in terms of output and low frequency extension. Like I stated earlier, the detail difference was very impressive. This was like going from a Ferrari F430 to their Formula 1 (F2005) car. What I had was great, but it was that much better. For less money, albeit more space.

annunaki,

Thanks again and again for the added details on "detail" . . . you're right on target with what I was looking to find out!

I think the central issue has to do with "target audience"; Velo, though they make some incredible upper-end stuff, is primarily a "music for the masses" company (with regards to consumer-level products). Thus, unlike SVS and some others, they put an emphasis on small form-factor. Take the HGS-X12 for example . . . what could that driver and amp do in an enclosure the size of the PB12-Ultra?? Regrettably we'll never know (unless someone wants to do some modding) because Velo knows: 1.) The value of WAF 2.) Their volume competitors are operating under the same "keep it compact" constraints.

Ah well . . . looks like I'm again down to deciding whether to order Hsu or SVS . . .

i went and listened to the PS-10 and the JBL e250 (using a pair of beta 50 as speakers)

i dont know what happened to me if i got deaf or numb, but i simply cant FEEL both these speakers (i sat in front of them) the PS-10 simply didnt have the power, the JBL i couldnt feel unless i was standing far away ... the sales guys said it was because it was a "long-throw" sub ... is this for real?

 

[MDS]

If the sales guy was implying that you cannot feel the output of the sub unless you are far away because it is a 'long throw' subwoofer, then he frankly doesn't know anything about bass. Long throw refers to how far the woofer cone moves.

I think he may be getting at another myth. The myth is that because low bass has a very long wavelength, you have to be at a distance that is an exact multiple of the wavelength to hear it; eg., if the wavelength is 14 feet, you wouldn't hear anything unless you are 14 feet away from it. If that were true, you wouldn't hear any bass in a small enclosure llike your car and you wouldn't hear the crack of thunder unless you were far away from the source.

If you didn't feel it, then it was either calibrated incorrectly or just doesn't play low and loud.

 

[mike c]

thanks MDS, with the PS-10, im guessing it was just plain weak. with the JBL e250 im guessing it wasnt calibrated correctly ...
its like something is pushing me to make decisions here
it just so happens that ive never even seen the beta 50 until yesterday when i was auditioning the subs (they've never displayed it before) then wallah! its there
then this thing with the subs ... i guess its velodyne then

 

[mike c]

is there such a thing as overkill on subs?
room size is 13 feet x 23 feet (8 feet ceiling) = 2392cu.ft
but listening area is only 13 feet x 15 feet = 1560cu.ft

choice:
Velodyne CHT12-R USD589
Velodyne CHT15 (no remote older model) USD734

There are a ton of options in subwoofers and a lot of good choices out there. Some companies choose to make a full range of budget to higher end models (Velodyne) and some people choose to compare their cheaper units as a reflection of what the entire line is like.

I personally fell in love with the HGS lineup from them and after listening to about a dozen other subs, decided that the Velodyne HGS was the only way to go. Yes, the 10" model doesn't hit as low, but it is a controlled smooth bass. Not nearly as boomy as many subs of that size.

I ended up (currently) with a HGS-18 which is a monster in a 15x15x9 foot listening area. Usually I have the volume fairly low, but when the friends are over and the wife is out, the volume goes up and it pounds.

I get the 'expensive' bit though. I'm not in the situation to get one 'brand-new'. But, the HGS-18 only ran $1200.00 through Audiogon and has been great. Plus, I sold my old subs for about $1100 so it was about a wash. Of course, buying used may just be to scary for some people. I've been extremely fortunate with my eBay and elsewhere purchases.

Well, I Know for sure those subs are not overkill in that room. I think the more, subs the better. The less each driver has to do, the less distortion there will be, as it will not be driving as hard. I tested the DLS-R5000R (cht-15R) in a 20 by 20 room, and it was not neer overkill. I don't know how high the volume was, but it was not killing.

i heard bigger subs are slower? so is it better to buy a big and small one in combo?

Thats voodoo. If the subwoofer was slower, it would be playing a difference note altogether. 18inch drivers can be just as "responsive" as an 8inch. All you need is a big amp, big magnet, and a stiff spider. Trust me, the CHT 15 is not slow. That subwoofer will do just fine in your room, or you could double up for some real fun

PS- People mix up harmonic distortion and speed.

Sheep's right, but while an 18" driver can be just as responsive, it does reproduce the higher bass frequencies as well as a smaller driver. You can get an 18" driver to do this, but at the cost of ultimate low end extension. Velodyne is one of the few companies I know of that makes an 18" sub that with a good range. Velodyne makes a 2 way subwoofer with an 18" and a 12" cone and one MONSTER amp. However, this subwoofer is like $10k.

And make that 2 MONSTER 1250WRMS amps
