From a Close Minded Audiophile--Sumiko S5 Subwoofer Helps

I thought I've never met a subwoofer that I liked.  Well, I stopped auditioning them when I left home theatre in the 90s and never looked back. 

I hooked up a Sumiko S5 two days ago.  At first I thought it sounded wonky and, while better than subwoofers that I remember, not for me.  I was pretty certain that I would be sending it back.  

I didn't use software to set it up.  I simply experimented with tons of fuzzy logic, real world trial and error.  I found the best setting was at about 45hz on the crossover, and the gain set to about 11/10:30.  The unit is hooked up to my Creek Evolution 100A integrated amplifier via Speakon hookup.  

The results are superb.  You cannot see the subwoofer (it's placed adjacent to my mid century media center on the right wall).  You also cannot hear it--at least there's nothing directional or flubby coming out of it to give its presence away.  I've played guitar for many years and I used my ears to painstakingly tune the unit in to a point where it ever-so-slightly overlaps my floorstanding PSB Imagine T2 loudspeakers bottom end.  The effect is very subtle, yet impressive.  The way I have it set up makes it doing so little;  it's merely rounding off the bass on the PSBs.  This allows drums, stand up bass, and electric bass to sound fuller without ANY of the bad bass that I do not want. 

Let me just say that I listen to 70% vinyl, and about 50% of that is jazz, 20% acoustic/folk, and the remainder rock/pop.  I do not want to hear sounds that do not sound like instruments being played in a studio.  I hate bloated bass.  I only want to hear notes. Well, that's exactly what I have. 

The introduction of the Sumiko has pushed the gestalt of my listening experience to a spot where things are overall better.  The midrange and highs are in no way adversely affected as I have this thing set up.  Indeed, the imaging and realism seems to have opened up in a very nice way. And, I don't have to drive my amp as hard to get the scenario to be believable.  I have much more fun at lower levels than previously. 

I'm curious as to others' thoughts, opinions, comments, experiences. 


Thanks!

I have 2 REL t9's (very similar to your Sumiko but bigger) and they are the first subs that i can stand. Others seem strangely disjoint from the music. (I an disregarding the 1 note wonders that people crank to show that "I have a Subwoofer!")
I think that the Speakon connection simply cuts through all that DSP / slope / rolloff / crossover jive, and you can achieve outstanding results with your ears. Maybe use a sound pressure meter.
I don't like DSP's, or 4th or even second order crossovers - they introduce too much delay/phase etc. anomalies.
The internals of the REL/Sumiko seem to have a simple, elegant solution and just work.
That said, I wish I had gotten the next size down, the t7i (I think).

I agree with setting the Sub(s) up so they energize the room the best, then introduce your mains.
And then make the adjustments on the Sumiko, not the amp or room correction.
