I finally added a second REL Sub

Seems like much gets lost in translation.  I do follow the REL method--nearly to spec.  But, even REL recommends fine tuning. What I was saying is that I do the fine tuning by ear listing to actual tracks with actual instruments--i.e. isolated kick drum, isolated stand up bass, and so on.  Then, I also listen to a group setting of those same type of instruments--sometimes the same track where things get busier.  

I tried DSP, mics and software.  Helpful for sure, but I didn't feel it was necessary to get into the very sweetest spot of linking it all together.  Wh


I've owned the CWIVs for 6 months and have experimented with all sorts of placement options, so at this point I'm confident that I cannot get the same low frequency with the CWIV through different position.  Actually, they are not bass monger designs in the first place.  And further, if I try to position them differently I surely can "up" the bass, but that position is not ideal as other things suffer.  

There's more than one way to skin a cat I suppose.  I'm smoking some ribs today.  In nearly all circles, cooking ribs fast is nuts and not appropriate.  I would never do it. But, there are experts who do and there are experts who don't who have tasted fast cook ribs and applaud them.  

I guess I just haven't found measurements as a panacea.  I built a handful of tube amps and a pretty involved preamp design.  Testing was important and shouldn't be ignored.  But just because it tests near perfect doesn't mean (TO ME) that it sounds better.  

Tuning a guitar by ear in seconds took years to master.  I can do it and meet 440hz spec.  With all humility, I'm not saying my ear is as good as a machine.   I also enjoy it. 

Here's to enjoying the journey!

What I'm saying is that I (or you) could buy a couple of no name brand 8" subwoofers and do the exact same thing. There is nothing musical to how you have these set up in your room. You mention sub bass, sorry that starts at 20Hz, these subs only go down to 28Hz. These are HT subs, so by your own words are not musical. The volume is so low, where's the music?

I just don't see what you're doing is anything to cause someone to create a thread about. As I said before, any novice can do what you did, except you spent $3k (list price), that could have been done for $300.00.

Personally, I'm more interested in here's a before and after thread - show us something interesting. 

I’m using two Velodyne HGS-15s to supplement KEF Reference 1s below 80 Hz. LR output from an Ayre KX-5/20 preamp goes to a SMS-1 bass manager that provides acoustic room correction for the HGS-15s. The sound is superb, never aware of the individual speakers.

Now for complications: I have a third HGS-15 and three HGS-10s. It’s been suggested that I use LFE from a Bryson SP3 processor I use for surround (front LR through Ayre by-pass) to the third HGS-15. I could use a second SMS-1 in pass-through mode to the three HGS-15 as a distributed setup.

I had a passive balanced 80 Hz 24 db high-pass filter built to insert between the Ayre preamp and amp, but it seemed to remove just a bit of the sense of air, so I haven’t been using it.

Advice about the subs and/or high-pass would be appreciated.

Golfnutz, ?! 
Thanks for saying my thread is pointless. Yes, if going out and buying gear and setting it up as the mfr suggests is novice and not to your liking, the lions share of posts here are just that. 
I must be an idiot along with others and REL to do this when $300 would give me the same result!  Thank you!!! 

Dear @jbhiller  : @golfnutz and @james633 and @dbphd  are rigth and seems you have a misunderstood about the use of two self powered subs in a stereo home system sound reproduction. Btw, mozartfan is totally wrong on this particular issue

Please read this link:

Obviously that you need to have true subwoofers that can goes below 20hz and maybe an external crossover that with some subs you could need it and with other manufacturer subs you just do not need it. Just in case:

Btw, at your seat position two well integrated subs are enough, you don't need 4 subs and I repeat: at your seat position to listen stereo MUSIC not HT.

Regards and enjoy the MUSIC NOT DISTORTIONS,
