Hi all,

I am thinking of upgrading from a pair  Force (running stereo 5 feet apart from each other)  to one or may be 2 Titans.  MY room size is 17 x 17 x 8  with an opening about 5 x 15 x 8 hallway and a stairway up to the main floor.    For HT, I am very satisfy with my current setup.   I cannot tolerate any higer vibration and pressure in movies anymore.  

However,  for 2 channel musics, I am hoping this upgrade will increase the impact of drums when playing light rock such as Jennifer Warn or jazz types of music.   I don't have the floor shaking feel when the kick drum playing.   I am not sure this is due to 10" drivers are not moving enough air to make my heart feel the kick drums ?   Overall drum play music is not realistic enough...

Will this be the problem of the volume of the 2 Force are not loud enough ?  (I don't want to crank the volume all the way up to get the over boomy noise from them either)

Will my goal achievable by upgrading to 1 or 2 Titians ?  What about 1 Titian and 1 Force ?  Will it cause unbalanced base in the room for stereo setup ?

Many thanks in advance..

Sounds to me like you don't have your subs setup right. Take the time to really play with the controls and placement if you can. I owned a Force and it can do what you want but you have to adjust it correctly. A pair should do the job very well but of course you know stereo pair requires even better setup

Try stacking the two Force subs and create one large sub rather than two seperate subs. Easier to setup and tweak.

i have just purchased my second force. how do oyu suggest stacking them? seams like that would mar the finnish and be prone to vibration knocking th etop sub off onto the floor. what way do oyu fix the 2 together?

I will jump in here as I have been doing a lot of reading recently on Audio Asylum and other sites regarding subs, room TX, and speaker setup.

You have wonderful equipment-state of the art level.
Your room is not really that big.
My uneducated hunch here is that you should try some Room TX before switching subs, more specifically maybe some DIY Bass Traps.

Surprisingly, Bass traps will increase the bass in your listening position as they help clean up some standing waves and cancellations going on.
I did a simple experiment a couple weeks ago and brought home some bales of Cellulose commonly found at Home Depot or Lowes (5$ a bale). I piled them in the corners. Bass tightened up and overall punch increased. Bass hump in corner of room where I sit at computer was now gone.

As for the placement of two subs-there is surprisingly a lot of research and comments on this on AA and on the web.
It is actually an inherent good thing to have two subs with regard to disrupting standing waves (it excites the room better). From what I have read-some have suggested to place each sub near (within 4 feet) of the corresponding main speaker opposite each other.
Of course, nearer corners increases bass and possible boominess. I would set the cutoff to 80hz or below to reduce the chance of location becoming apparent.

My solution in my room which is somewhat bigger is to do some basic DIY Bass Traps and I am adding another sub.
My room is 17X25X8 and has a staircase that adds even more cubic footage. Probably about 3100+ total cubic feet.
I have one Titan now (older version) and found another one which I am picking up later this month.


The last thing I will say since you have a very transparent and accurate high end system is that bass can vary tremendously on different recordings and that has little to do with any deficiencies in your subwoofers.
When I listen to Jeff Lorber-Philly Style the bass is huge and organic.
When I listen to an older Lee Morgan recording the bass is light.
When I listen to Bill Evans Village Vanguard live recordings the bass is palpable and real.

It just depends. High end audio gives you what is on the mastering for better or for worse.


Here is a good link on room setup that and TX that I like:

Hope this helps in some way.
For stuff on setting up two subs do a search on Audio Asylum in the Speaker Forum.

Hi,

Please let me know how you making out with the stereo Titian sub in your setup.  How far apart you are placing between ?   I am upgrading to a BAT VK60 tube amp (will pick it up by the end of month).  I am hoping to get better mid and high.  I will have to rely on my stereo Force to give me the tighe and deep bass..   I will research on bass trap as you suggested..

Thanks again..

oris98-

Got my matching ACI Titan sub (older version) set up tonight for the first time. I had to wait a couple weeks until I was able to pick it up from the seller.
As for placement- I have each sub outside my Jaguars about two feet away (center of Jag to center of sub) and about halfway behind them. The Jags are on heavy duty 28" DIY stands.
The Jags are 8 1/2 apart so the subs are then about 12 feet apart and a foot or so away from the sidewalls and four feet or so out from the backwall.

Right now I have the Phase on 0; the lowpass at about 60hz, and the gain at barely over the second marking.
I have the ports plugged on the Jags so they are supposed to roll off around the 60 hz mark also.
Will work on fine tuning the settings this weekend, but I ma pretty close I think.

The two subs in my room seems to do a lot of good things. There is an ease on the lower end now that was not there before -more presence, but it is smoother and seemingly deeper with less effort than before.
My room is fairly large as noted (over 3100 cu feet) so your mileage may vary in smaller rooms, but I like what it seems to be doing. Supposedly two subs excites and disrupts standing waves which also helps the overall sound presentation.

I am pretty happy with the result and these older Titans are a complete steal on the used market. 20hz of buttery low end clean fast musical bass.
