Do you think you need a subwoofer?

I went from 2 subs to 4 this weekend . The distributed bass plan works like a charm the bass response is even around the room and the whole system just sounds right .

Hi Tim

My sub system is using 4 REL q201e subs . I have a set of custom Ohm Walsh 2.2000 speakers that are 13 " high that sit on top of the subs I run my front subs in stereo and use a DSPeaker Antimode 2.0 for LF room correction .The other subs in the rear of the room were hooked up to my HT pre pro LFE . After hearing a distributed bass system at a listening session I was hooked . I reconfigured my LF system . I added the two rear subs into the stereo mix keeping each side of the room on the same channel . too control the rear subs I am using a Mini DSP 2x4 beats crawling on your knees to make adjustments .Adding the rear subs evened out the bass response in the room and made a huge improvement in the system . I am still tweeking the adjustments. I should have tried this sooner a big change ! 

Hi Noble I have my own placement restraints as i live in a Manhattan apt. I spent much time configuring my system for getting the best sound while meeting the dreaded WAF . To save floor space my Ohm Walsh 2.2000 speakers are in short cabinets that sit on top of the subs the height is set to put the tweeters at ear level . My speakers are now sealed and don't work well at 32 hertz . I installed signal line caps in my tube amps to cut them off @  50 hertz . I upgraded the amp for the two front subs with a Crown XLS2502 and set the crossover to 60 hetrz . My DSPeaker is paired with a custom DIY built Bent Audio auto former volume control . Yes I have and use tone controls in the digital domain it is transparent . As for the Mini DSP 2x4 I am using it to control the rear subs only it is very flexible .I have the two rear subs in the rear corners out of sight . I read the instructions for the Debra system and am trying the polarity invert . I  have been using DSP controlled stereo subs for about 3 years and after hearing a distributed bass system I was convinced . I am loving this arrangement . Thank you for the advice .    

Hi Tim getting back to the best bass I have heard in my system . I have been using DSP controlled stereo bass for three years with great results . After hearing a dynamic system with 4 subs I was inspired to try it myself .My system is centered on a DSPeaker anitimode 2.0 the DSPeaker only has I analog input I paired it up with a DIY 4 input 2 output Bent audio TAP x passive autoformer volume control . the DSP is inserted in a in and out loop . For amps I am using a pair of modified VTL 100 mono blocks using 2 KT-120 tubes ea. puts out about 75 watts . My speakers are Ohm Walsh 2.2000 in custom cabinets that are placed on top of the REL Q201e subs . The power amps have caps in the signal lines to cut the L/F off @  50 hrz . the subs take over from there . I use a analog as well as a digital front end . And for movie night i have a Outlaw Pre Pro that is another source and of course more amps and speakers . My system is far from simple .The only simple thing is it can be turned on with one button that was so that my technically bankrupt wife could use it . I had to design this system around the limited space I have . After adding 2 more subs at the back of the room the bass response has evened out much more then with the stereo subs . Works like active room treatments. All I can say on good recording I give myself goose bumps and that's with both digital and analog . And Raul you may piss off some people but you make us think and that's not bad its good science .RC
