The system components have remained largely unchanged, but for the additions of a large Minus K platform for the turntable, a pair of 15" subwoofers to augment the lowest octaves and the installation of a robust electrical sub-system--powered through a Controlled Power 10kVa isolation transformer. The main change is the room--we relocated from New York to Austin, TX in 2017 and I now have a longer, narrower room that occupies most of the 2nd floor of the house. I have added a few photos reflecting updates since 2017. Bill
My issue would be the same as Bill's woofer amps. The hum is not that loud. You can hear it if you put your ear to the amps. I found it helped some when I plugged both woofers into a PS Audio humbuster III.
Bill, I'm located up in Canada, Vancouver, B.C. A little far away from Tx. Anyways, do give me a shout if you are ever in the area. And do look up the Tact Audio W210 woofers on google. They make a world of a difference.
I would love for you to come over if you were a little closer to let me know what you think. I've been fiddling for a long time and i think i've finally gotten pretty close to my nirvana. I've tried many speaker placements, different crossovers and a LOT of tweaking with the target curve. There is another member here that is running Avantgarde Trios with 3 pairs of the Tact W210's. As soon as i receive my second pair of W210's, i will update my 'system'. Prior to my avantgardes I had B&W 802N's running with passlabs x350.5 and X0.2 preamp. Although this setup sounded good with vocals, with more upbeat music the speakers seem to struggle to keep up. That's when i did some research and made the switch to horns. From there I changed my pre and amp to all Tact equipment. I own a 2004 M3 cab 6 speed not smg;-)
Regarding your A/C issue (not sure if you've resolved it by now) I'm running a Fujitsu heat pump which does heat and A/C. The main unit is situated outside and they mount the fan unit on the wall in the room. It's pretty quiet when you have it on the "quiet" mode. The unit outside is very quiet as well. You can use it in the winter for heat and summer for A/C. Check it out.
Thanks for the reply. When i acquired my Uno's, I couldn't stand the humming coming from the woofers as my room is VERY quiet. I can hear a pin drop in there ;-) so i've looked into replacing them with a different woofer that is inexpensive and fast enough to integrate with the avantgardes. My friend has a full Tact Audio system comprised of a 2.2x preamp, 3 x s2150 amps, a pair of Tact Audio MTM style bookshelf speakers and a pair of Tact Audio custom made W410 woofers. The thing that interested me was his woofers. They can crossover up to about 400hz which is perfect for my Uno's which needs only to be crossed over around 260hz. Few months ago i purchased a pair of Tact W210's to try out and to my amazement they integrated very well with the Uno's. From then on, i've turned off the 225's and my room is dead quiet again :-D They don't go as low as the 225's but i'll sacrifice quality over quantity anytime. I'm also running the horns with a full Tact system: 2.2xp preamp, 1 x s2150 amp, 2 x s2150xdm amps. You will NEED the 2.2xp to correctly integrate the woofers to the horns as it will calculate time delay to the horns.
