Monitor speakers on top of subs

[coot]

I listen to a fair amount of music with pipe organ in it. In the interest of reaching below 20Hz, I am considering replacing my current floorstanders with subs with stacked monitors on top since floor space is limited.  Anyone else doing this? I would assume isolation between the two would be important. Are there problems I should know about?

If your current floorstanders are suitable for your needs except for very low bass then just adding a sub with very low frequency crossover should work. Low frequencies are not directional so the sub could theoretically be placed almost anywhere.

 

Both isolating the monitors from subwoofer vibration and ensuring that they are rigidly mounted could be difficult or ugly.

Adding a sub is out of the question due to lack of space.

Are you using room correction software? Changing speaker solution sounds like you are attacking the wrong problem.

 

 

Thank you all.

Current spkrs are Ohm 5000s which are not imaging very well in my space + they don't go low enough, so thinking monitors + subs will.

Re: RC, It would need to be digital between Aurender N100H (usb only out) and W4S DAC. Looking at DSSpeaker. Adding RC still doesn't get me the below-20Hz I'm looking for.

OK - more research has me setting 24" tall Tekton Impact Monitors (isolated) atop a pair of 25" tall Powersound V1510 subs (isolated from floor). Preamp, crossovers and room correction would be handled by a DSpeaker X4. At a later date I will power the monitors with Primaluna tubes.

 

On paper at least this gets me from well below 20Hz on up. 

 

Comments are welcome.

Hi Coot, out of curiosity what solution have you chosen?

l’m asking as in a somewhat similar situation - pipe organ fan, purchased active monitors (Focal twin be6) yet still unbalanced as for the subwoofer...

No decision as yet. Still scraping $$ together. And I haven't yet approached HER about it...

Thanks, bobbmd. Thinking now about Kii 3, and be done. Saving up.
