Mmmm Crow tastes good...

I used to be anti-sub, but knew I was missing out on some good bass. I had extreme difficulty integrating one into my system properly, but eventually managed to make it sound decent enough. But it was still too muddy with poor resolution on the low end. My listening room is rather small & awkwardly shaped so the acoustics are terrible. I tried room treatments. The affordable option (egg crate foam) worked fine but wouldn't pass the wife test. I'm too stingy to splurge on treatments she'd approve. I recently decided to try a miniDSP DDRC-24 with the Dirac Live room correction software. I'm not sure what manner of sorcery it is, but that little box works MAGIC!!! My system now sounds like the professional setups I've heard when auditioning in AV shops. I now get fantastic resolution on the low end even at lower volumes. I'm now totally pro-subwoofer.

It may be blasphemous to the audiophile community but I highly recommend miniDSP as a reasonably affordable way to help with bass (subwoofer) integration issues and room correction in general.  If you have the right equipment I suppose it may be possible to just get the DIRAC Live as standalone software. I know there are other correction options that are probably just as good (like Room EQ), but this is the one I've experienced and liked. I was unimpressed by Anthem's software that I use for a secondary setup.   

@osiris369 I’m definitely not anti-DSP. If I had a system that was mostly giving me what I wanted I’d definitely look at DSP to tie the room together.

@millercarbon--i have fairly full range speakers (Aerial Acoustics 7t) but also have a sub that i have not, to date, attempted to integrate mainly because i found it so difficult before with my prior standmount speakers and only recently learned that using more than one sub is better--

1. If i buy another sub (my listening room is small -16"x 14' on the left side but 14'x14' on the right side due to a closet--so i probably wouldn't go for more than one more sub) is it better to buy the same size/same brand or does that really matter?  The sub i have is no longer made although the manufacturer is still in business but i'd hate to have to buy two

2. I know where the standing waves are in my room and also where the bass is virtually cancelled--when locating subs do you put them where the waves are reinforced or where the bass is weak or ?  I have a pink noise generator and an RTA on my phone so just wondering if i can use just those to properly locate a sub?  FWIW I can't do the crawl due to really bad knees.

Thanks for any tips

@wyoboy: what's the difference between the aerial 7T and the 7B., If you don't mind.

sorry--no idea--although they look similar--7t is more recent
