Kick in chest bass

[slisgrinder]

Hey guys,


First time in this forum, but didn't know where else qualifies for my questions so here goes nothing:


I am in the process of designing my own 5.1 surround sound speakers but have a question on the type of sub that could reproduce the "kick in chest" feeling. I recently went and saw Star Trek and felt the "kick in chest" effect when the Enterprise jumps to warp.

Size is no problem nor is time and I am willing to spend the next five years to design this and save up money, buying part after part, but I want to make them myself.

I am a complete noob at audio but my dad got bose for himself and I was stunned, then I bought myself the Logitech Z5500 for gaming and I am satisfied but still can't get that "kick in chest" feeling. I want to build with patience and would like to understand every fundamental that will help me build them and I am trying to be independent here.


Thanks for your time guys...

First of all...how does the Bose sound,is it better than the logitech?

Secondly,are you trying to build the woofer on your own?(DIY)


Lastly,I'm new to...Ever heard of a Plasma Tweeter??? 0.o

The KAPPA DIY sub will kick you in the chest and nuts and can be made for little money. I would look at getting some good mains and then building one depending on room size and budget. A guy could build this system using some as simple as some Behringer bookshelf speakers and the KAPPA and it would blow away any BOSE system for a fraction of the cost.

Another new guy here.
First this sight rocks you will get pretty much everything you need to know right here.

and the two things you nevEr should mention on this sight is Bose and HTIB *Home theater in a box...
GOOD LUCK

Because we are mostly talking about HI-FI systems on this sit and the Bose is about as LO-FI as you can go and sound like crap to boot, but with their excellence through advertising peple get suckered into buying them. Now it would be different if they sounded great if they did you would hear about it on here also.

Thanks for your stat replies, and I didn't meant to start a fire here, the only reason I mentioned the not to be mentioned names here was because thats what my background experience is for listening to music.

but anywho, what I meant was what type of enclosure would give me that "kick in chest effect"? The rest I will figure out and if I need help I will know where to come (obviously here). So am I looking for a high SPL design???

 

[captiankirk28]

What is your budget, the Kappa builds that you can find lots of info on here about is a DIY option and is a great sub, Other companys to look at are www.svsound.com check out their PB Ultra 13

 

[slisgrinder]

ooh, there are such things at cylindrical subs??? kewl...


ok, if room size matters here are the dimensions of my listening location as h x l x w ==> 8' x 20' x 22' and its in a basement so the floor is concrete, 3 of the walls are concrete the cieling is the typical drywall beam etc and the 4th wall is the typical drywall, studs etc.

The budget is somewhat of a student ($3000 CAD for the entire 5.1 system) but will be building it myself. I looked at the kappa builds and after looking at the PB13 Ultra, it seems like they all use ported bandpass reflex enclosures. My question is what type of enclosure enables it to have that impact effect in the chest? Is it a high SPL at a certain frequency that I am experiencing? Or is it completely dependent on other factors?

I apologize in advance if I am being difficult or not clear in my question.

Im sure it is high spl at a certain frequency but the better the the higher the spl the more you get your *** kicked watching a movie

 

[slisgrinder]

so can I achive high SPL in the room size I mentioned above with a number of smaller drivers in each corner or can I accomplish this by some other means as by having two 15" drivers, one in the front and one in the back?

 

[lsiberian]

I suggest you look at a Pulse Axis 15" build pair that with 3 pairs of behringer 2030p's and you will have a monsters system(just don't buy the monster cable).

Since size is no object A nice ported monser 15" build would rattle your entire house.

You could also do a Kappa build or Maelstrom build.

 

[lsiberian]

My planned approach is to use 8" drivers as MBMs and my 12" as the lower sub.

If I had a larger budget I would probably have done a tagband sub at each speaker spot. and a single deep beast with a Maelstrom-X

 

[slisgrinder]

Whoa, some of the lingo I cannot understand, could you please explain to me what you mean by MBM, tagband? And wlsiberian, I want this system to be completely DIY as my aim is to give my dad a surprise with this as he is hard of hearing in one ear and values sound quality more than anything...

The AudioPulse Axis look amazing, but I am wondering if they would be over powering. I just need them to kick in the chest at the right time while not fatiguing when listening. This is aimed at the general Hi-Def movie watching and uncompressed music listening.

I want to go for multi-sub placement rather than having one sub with multiple drivers as its hard to reproduce proper bass in a basement. I would like to have atleast 4 subs each one placed in each corner of the room but don't know what size the driver needs to be let alone the enclosure type (vented/ported what "order" etc) also is it easier/ cheaper to make them passive or active (powered by themselves)?

You need a powerful sub for that experience and not cheap. SV S has some good ones for that kick.
Went to one of those Cirque du Soleil that has very heavy bass and some just knocks you out almost. Had to cover my ears.

 

[slisgrinder]

Well, I my aim is to make this 5.1 system on my own so DIY is my approach. on another note, is there calculation involved in making speakers (more so shelf/column speakers) if so, is there a tutorial or some educational material on these???

My system when completed will be compossed of Vifa drivers in Constraint layer. Highly dampened and braced boxes. Paired with JL Audio 8w6s highly damped and braced in MBM boxes and one monster sub to take care of the sub 50hz range.

First I will suggest you look at what drivers you might want to use. I suggest either a sealed or TL approach except for the sub.

Subs. Their are many options for drivers. But some of the gems are JL Audio *w7s(even the 8" are amazing)

Infinity Kappa Perfect.

Anything Exodus Audio makes

Anything TC Sounds

anything Audiopulse.

The sound splinter line.

For MBMs or even the bottom woofer I suggest Tagbands, or JL Audio 8w7s.

For midrange Vifa, Seas, Pearless, Scanspeak are all good deals. What you get depends on budget and preferences

The recession buster kit is a great deal. www.madisound.com and parts-express.com have many kits.

 

[slisgrinder]

What do you mean by MBM/MDM? And my heart is set at making tower speakers for the Left, Right, Rear Left and Rear Right with the center being a long Horizontal similar to the previous ones but simmetrical. As for the subs, I was hoping for having something like 10" in each of the towers excluding the center which will give me good impact. The only question remains is what type of crossover order should my subs be to deliver that "kick in chest" effect? any ideas?

 

[slisgrinder]

I have been doing some browsing at parts express and found the following:

Tweeter...

Mid-range driver...


And I plan on using two of the mid-range drivers and one tweeter in each of the front left / front right / rear left / rear right towers and four of the mid-range drivers plus two of the tweeters in the center. Is this a good combo? if so the only question remains is what should I do about the bass??? should I have small 8" subwoofers in each of left/right/rear left/rear right towers and a slightly bigger 12" subwoofer or go for two 15" drivers one in the front and one in the rear??? and how will this affect cost while including the electronics such as amps etc for both approaches mentioned???

For towers I suggest the Thor TLs. http://www.audioxcel.com/audioXpress Thor Review.pdf or a 2-way design with a mid bass module

For a center I suggest A Loki Coaxial TL.http://forums.audioholics.com/forums/showpost.php?p=535920&postcount=6

That thread has a lot of very good posts especially from TLS Guy.

MBM = Mid Bass Module. It's what goes between the speakers and the subs.

I use WinISD to generate internal volume.

 

[slisgrinder]

kewl...thanks, the Thor Tls and Loki Coxials look stellar, my dad will love this...
