Subwoofer


Looking to add a subwoofer to my 2 channel system. Problem arises in that there is only one location give or take 2 feet in all directions where the subwoofer can be. 

Very large untreated open concept room. 14 ft tray ceilings, about 30 ft by 20 ft. Hardwood floors. Serious WAF. Maybe one day will have dedicated room but for now should I wait, make it "work" with eq, accept the limitations of the location, hope it works?

Suggestions please. Maybe a particular brand addresses this.

Modwright integrated, vintage Thorens, Innuos streamer,  Kef R3. Kef LS50. Usher 530. Watkins.  Ryan R2.

Mijostyn is right for me...

I added ONE sub few years ago, because so good was the Mission Cyrus in the bass  they are not  good up to under 45 hertz and organ music goes under...

I disconnected it the same day and sold it... ( Kreisel k9  sub )

integrating subs is a job of his own...

@jpwarren58 , If you try adding just one subwoofer to your current situation you will be very unhappy with the results. I suggest you wait until your circumstances improve. At any rate adding just one sub is never a good idea, Two is the minimum.

Thanks ditusa...

Very good article that seems to detail and explain well my own bad experience with a SINGLE subs added to my system... I sold it because i was not prepared for this task at all ... :) In the mean time i learned room acoustic and i discovered why connecting a single subs is a bad idea most of the times if done without any help....

Now my headphone goes under 30 hertz i dont need subs...

 

 

This article is very good :

«

Understand that the largest percentage of all audio issues is room acoustics. You cannot put a great speaker in a marble shower stall and expect it to sound good - it will sound like a speaker in a marble shower stall. Room acoustics itself is a very complex set of interactions of physics and perception.

Sadly, there are many instances where manufacturers or individuals skew the relevant terms and confuse people. For example, beware of (and be aware of) the dangerous term "Room Tuning". You CANNOT tune a room using an "equalizer". You are tuning THE SOUND SYSTEM with the equalizer - the room is still the same. REAL room tuning means anything from sticking pillows in the corners to rebuilding the room (perhaps correctly) from scratch, incorporating a set of acoustic devices and parameters which sometimes seem nebulous but get a desired result. Because of this nebulosity of all the acoustics terminology (not to mention the international differences in measuring techniques, terminology, and ’scales’, which are substantial) it is often difficult for an end user (and many audio professionals, for that matter) to be able to mentally visualize just what a room without standing waves will sound like, or a room which is so rolled off that the high frequencies seem to "fall to the floor". »

 

What he wrote is so true, understanding it i rejected the idea of using an electronical equalizer first and instead designed my own room MECHANICAL tuning... First i used passive treatment with a balance between diffusion/reflection/absorption... After I created my audio room with one hundred Helmholtz resonators tuned incrementally on 6 months period around my listening position and the speakers ... I called that : "a mechanical equalizer"... The results were stunning.... No speakers at any price can beat the room...And a good room easily beat most of the times any speakers at any price in a non dedicated room...

 

By the way half of the issues and problems with headphones are related to the shell acoustic relation with the driver and the acoustic content of the shell or lack of...Something headphone marketing never adress, because to sell a product you dont point to the problems but to false solutions : improved driver with a thinner membrane for example... It is not enough to have a good driver, all my past 9 headphones had good drivers, none had acoustic content and device  in the shell/cup, save one... The only one i like... AKG K340...

One sub is very hard to put in a musical synergy with the speakers...

But if someone want only boom boom sound , it is very easy to plug it...

I plug mine few minutes and sold it... 😁 because i could not think how i would make it "musically integrated" ... i think that it must takes 2 ...

A balance sound is not a boom boom sound added...

But my short experience with ONE sub  ( Kreisel K9 ) was not happy and i could not figure out a way to integrate it "musically"  ...

But once this is said i am not a sub woofer specialist at all...But i love music and i hate boom boom... Perhaps i am wrong and there is a way in some room to do it musically with ONE sub... We must ask to a sub-woofer specialist for confirmation or debunking ...My intuition is location and room dimensions are very important for this problem then there is no absolute rule and in some case one sub can do the job perhaps... In most general case i think it takes more than one...

Bass play a great role enjoying the music...Even for localization ( phase angle) and imaging and soundstage...

And hearing tuba clearly and deeply and organ bass note is like , time to time making love with a plump woman and not always with an anorexic, an another cosmos of love or sounds... :)

One sub only , everybody say it, is very difficult to balance ( impiossible for me in my experience)...

You are spiritually and syntactically irreplaceable here... I am glad to spoke to  you again...

@mahgister , it is good to 'see' you again...*vbs*

As one who's lived through both of the '60's', we're becoming rare instead of being merely 'well done'....;)

As for 'subbing it', a single self driven 8" for the moment, considering an array of 4; 2 - 8~10" left & right 'front", 2 - 6~8" L & R 'rear'...although 'placement' and levels subject to measure and taste....self-driven, perhaps...

All of which subject to the vagrancies of time, space, and budget....I need obedient clones....*L* 

 

Thanks for your kindness ...

 My very best to you....

@mahgister 

Glad to see you are here again seemingly healthy. At our ages, you never know when one may have passed.

I can assure you the Akg K340 are now optimized and so good i will never go back to the difficult task to tune a room... I dont need because  the three dimensional "out of the head" soundfield of my headphone beat my past speakers or rival them  ...

The K340 is unique headphone the most different designed headphone ever compared to any other... Read about it...

 

My best to you and your family...

 

thanks @mahgister I hope you are enjoying the music whichever ways, maybe nearfield listening with speakers is an option too!

I think grislybutter is right...

I bought a subwoofer years ago because my MIssion Cyrus never go down 45 hertz really...

With an organ music album it is a pity...

But the sub alone dont cure the problem and worsened it because the unbalance it created...I sold it on the spot... :)

I think it takes more than one sub  to balance the system and the room...

 Sadly at first but fortunately at last , my headphone replaced my dedicated room now because i sold my house... My headphone go so low under 30 hertz that i feel the wave with my body and feet by bones resonance and it is like the owgan was in my room... No sub is needed...And my new headphone beat my past speakers in their well tuned room..
