a 15 that hits 30hz or a 12 that hits 25hz

[ticks77]

ok well i have a dayton HF 12 now i like very much and i then found a bargin on a dayon HF 15.

so i either want to get the HF 15 (speaker only) (already have in my possesion) up and running or i could get something eles for the same price n sell the 15.

well i will have to get a box made and a 1000 watt amp which i can get both for 400$ the box design i will have them make gets down to around 30 hz (this is the biggest box i can have so i cant use a bigger one to get lower hz)

ive also seen some hsu 12s that i can get for a lil more that boast 20 25 hz.

but regardless of how low it will go i think the 15 will be louder 1000 watts is a lot of power plus i really wanna feel it


my athena LS-500 towers go down to 30hz and the HF 12 i have now goes to 27hz

i do have a big living room to fill, honestly the HF12 does fine i just found such a good deal on the 15 i couldnt help myself.

what would you do??

Is it a matter of scrapping one to build the other? If not buy the needed equipment to build the 15" and see if you like it better then the 12". If its a money thing you could always try and sell the one you like less.

i bought a 15" that vibrates the house at 20hz and you can most definately feel it, dont let the low 350w rms fool you, in a box this big it has alot of output

I bought the knight my room is 16'w X 27'L X 8'H and i am extremely happy

I use the same Rythmik amp with my 15" and it has more than enough output in my fairly large room as well.

 

[ticks77]

im not scraping one to build the other just wondering if i would be better off with a 15 that will hit 30 hz in the box i will be using or a 12 that will hit 20 or 25 hz. the 15 will get down to 18hz or lower just not in the box i will use

so basicly to fill a very large room would you use a 15 with a lot of power that doesnt go extremely low or a 12 with little power that will got extremely low.

and for all those with a 15 as ht is it too over bearing?

 

[kappa546]

so you're basically going to put the 15HF in a highly underdamped enclosure because you want to get louder. putting the driver in a less than optimal enclosure will hinder not only low frequency extension but will affect transient response.

tell us the size and type of eclosure the 12 is in and the 15 would be in.

 

[ticks77]

no its going in a huge enclosure with a huge amp 1000 watts 24 n 3/4s x24 3/4x 243/4 basicly a 24n3/4s cube the speaker will only hit 30hz in that box tho non ported .

so a 12 with low hz or power and size with less hz

There are some that say not to bother with a sub that can't extend down to 20Hz...

Upping the bass extention is probably not the ideal solution for movie enjoyment IMHO.

Stick with the 12in sub!

 

[ticks77]

but its a big *** 15 that will move a lot of air with a ton of power and those are just analitycal numbers would have to be louder than the 12 its a good 15 too same as the 12 only its a 15 in a sealed box maybe ill just go get a HSU mk 3 with turbo i just dont want to miss out on a 15 that would be louder and cheaper

Thereisaninterrestingprogressiontoyourpostformat! Lol

You've had comments going both ways. At the end of the day, whatever floats your boat is fine.

I doubt the 12" would have a lot of trouble filling your space (how big is the room anyways?). I have a SVS PB-12 Plus in a ~600sqft room (12" with 525W amp) and it can play stupidly loud and pretty low frequency...

He is asking a fairly simple question:

Should he go with a 12 inch sub that has a low range of 25Hz. Or, should he go with the 15 inch sub that will only go as low as 30Hz.

His considerations so far have been simple as well: Will the increased cone size and amplifier power of the 15 inch sub outweigh the benefits of the smaller not as powerful 12 inch.

From his posts, I am infering that he cannot have the optimal enclosure size and specifications to produce lower bass extension beyond 30hz, even though the driver is rated to go down to 18hz.

Not sure why anyone is having a hard time understanding him, though granted his post composition is not the greatest.

Regardless, my $0.02 is as follows; 30hz isn't really as low as you can go, and even though the 15 will be more powerful, you will be loosing out on content. Lets also remember that the lower frequencies are more felt then heard. That said, the 12 has the better bass extension. Albeit a modest difference of 5hz. For whatever its worth, I'd be looking into a sub that can dip lower then 20hz, but of the options you have given us I would go with the 12 inch sub. Bigger, isn't always better, especially when it compromises quality.

I'd be torn too, frankly.

I've always been a fan of 12's simply because the cone size seems pretty optimal for base reproduction. By that I would be referring to the propensity of a larger cone to distort through flex. However, I'd rather have a duel configuration for the 12s.

The benefit of the 15 is that it will have to move less to move a similar volume of air, leading to a reasonable conclusion that the 15 may play with less distortion. However, I'm not as familiar with the effect an incorrectly sized enclosure may have on that conclusion.

what would you do??

The HF series drivers are outstanding, but with a 1000 watt amp, that would be complete overkill unless you were using a sealed box in a very large room. If all you are concerned with is volume, you don't need a box that dips down below 30Hz. Great home theater bass is felt, not heard. My old Cadence was loud, but couldn't handle the stuff below 25Hz (and there's a lot of bass below 25Hz in movies). It's a great sub for music, but an average sub for movies. I didn't realize this until purchasing a Plus/2.

If you're looking for "loud" bass, you need some old 12" 3 way speakers for music. Two of those will go louder than most HSU or SVS subs with chest thumping bass at 40-50Hz. If you want something you can feel with movies, go with the setup that allows for the lowest bass in the proper cabinet. (you wouldn't put an LS1 engine in a Festiva - you'd never hook up).

Your Athena's (nice looking by the way) towers with dual 6.5" drivers claim they can dip down to 30Hz. That's most likely at -6dB. I'd say their useful frequency end is more likely to be 60-70Hz - pretty typical for today's towers. (My RTi10's dual 7" drivers and 6.5" woofer also claim to play down to 20Hz, with a lower -3dB limit to 35Hz. What they don't want to tell you is the useful bass at 0dB (goes up exponentially).

I'd say first decide if you want HT bass or purely loud musical bass. If you are limited on enclosure size, lean towards the 12" and optimize the output and Hz response. I would only go with the 15" if I could build the proper box that extends down to the 18Hz it was meant to play.

So you are tuning the box for 30 Hz limit so you can get more output at 30 and higher? I personally would have to add a seperate sub that got 30 to 15ish. I like all ranges and don't want to miss any of the music. I can't get below 20 Hz with my set up, but I want to add something else just for the extremely low end.

So I would suggest keeping both if you can. the 12 crossed over a bit lower for only the 50 and lower. A 15 should be able to play lower though. Just get the SVS 13 that's super powerful in all ranges. It's only $1500. ^_^

no dude im not tunning the box to 30 hz im putting the 15 in a 24 3/4s cube sealed box someone estimated the hz to be 30 i dont know for sure i dont have the software it might hit 20 hz someone plug in my driver in that size box and let me know what the hz would be
