ATC SCM 7 V.3 and

Yeah nice speaker...they do sound like there more in your quest.The atc are musical and natural to my ears, but the harbeth are sweet musical.I think that there are trade offs with everything/speakers.Harbeths played at lower vol is a +.

Harbeth...older iteration...probably newer crossover updates/changes,metal tweeter?

Atc ...Will throw a nice sound stage...need to have some vol to get things up and running.Wont have the throw the harbeth have... just physics/cab volume.

Aside from loudness buttons and great recordings (which is a big part of it)...i think having your system in good form to begin with is really necessary for a speaker to be able to perform at optimum low level...Speaker well run in,Quality stands/sound anchors work.Speaker placement dialed in...components properly decoupled made a huge difference for my system.I sometimes wonder how far people go to achieve optimum performance...At one point i was ready to off my atc 19 because i just wasnt hearing what i thought these speaker's should be capable of.It wasnt the speaker but was my lack of attention to stands and setup that was keeping them from performing.That done made all the difference... Not always the speaker that is the weak link.

Your amp rated 90 watts 8 ohms...The small room would be a +.I am in a 13 by 10 room with the 19’s,but ss 200 aside modwright.I still feel i could get away with more power.I started with the 11’s and went 19’s because of the driver in the 19 and didnt want to coulda shoulda to be a factor in purchase.I would even think the 11’s would work great in the size room.I originally thought the 19 might be to much for the room,not so.The design of no port really show how well controlled they are.

If more info and backup info "lonemountain"...really helpfull.No bs.A nice 12 gauge quality cable will help Amp to speaker.And jumpers...are the cherry on top.

Its really close to my specs room wise...you know what you want out of your system...Good stands and setup properly you may achieve a great sound stage with the scm 7.They may surprise you.Option to upgrade would be good.

I ended up toeing in enough to eliminate 1st reflection/just over shoulder.
