I bought the Impact monitors (3 of them for L/C/R) and loved them... best midrange I’ve ever heard in my house (In this house I’ve had MartinLogan, Maggie 2.6, B&W’s) I placed the L+R on top of my 15" HSU sealed subs... as shown here:
and for 90-95% of music, the combo shined...
but try as I might, I simply couldn’t get the gap between the mains (running full range with my BAT tube preamp, or HighPass crossed over with my Bryston) to blend "perfectly"** with the subs.
** perfectly = not distracting on specific tracks, like "You Look Good to Me" by the Oscar Peterson Trio - the acoustic/upright bass, with bow or plucked, just didn’t sound "as good as it could be" and my visit to Capital Audio fest proved it to me - I asked for that song on any system taking requests. Granted, for $2200 the Impact Monitors are awesome. And if you already have subs a total no brainer, espcially if you listen to only Rock, EDM, etc. But if acoustic bass is on the menu.... you may end up doing what I did or just go straight to "step 2"
I called up Eric Alexander at Tekton and told him what I wrote above and that I wanted to upgrade to a floor stander, but my 7’ height meant many of the full towers were out for me...
Well, turns out he had a pet project (which he may offer as a retail model) called a "Half Ulfberht" kinda half of one of these, but instead of an MTM tweeter array it’s a 7 ring like the monitors I loved. Sold. my basement listening room now looks like this:
And I am not bothering with bi-amping, the Buckeye Amps (Purifi based) class-D monoblocks I run are so good on their own, especially when fed by the tube powered Balanced Audio Technology pre-amp (I love my Bryston, but the BAT is even sweeter) but these came with 4 binding posts for bi-wiring, you can ask for bi-amping at time of checkout. Better yet, email them and ask for a callback from Eric, explain your needs - he’s been super responsive with many of us.
PS: I just looked up the Encore monitors... $3990... my Half Ulfberht’s were < $1000 more that those monitors. What you give up with this "half size" configuration vs. the "real/full Ulfberht" I linked to above: (1) sensitivity goes down by 3 (still 95-96dB @ 1w) and resistance goes from 4 to 8ohms, (2) power handling goes from 1kw to 500w.
PPS: and my subs? yeah, still connected, but instead of @ 80hz, they take over only < 30hz and only seem to help on EDM/movies at this point. The bass from the Ulfberhts is quite good on their own.
