I will play with it Sunday and post what I find. Eventually I would like to try a tube pre amp.

Will be weekend before I get to look at Carver. Little surprised I thought the carver would a bigger improvement over the interga avr. Carver had slightly better mids and highs ( less grainy,clearer ) and bass seem to extend a little further into the room but nothing major. Think I need room conditioning but lately life keeps getting in the way. Hopefully in the next couple weeks I can get a couple days dedicated to audio.

Interesting thanks! I used pre outs from interga to carver amp and then to mains only, high power outputs to all others speakers. Worked so pre outs and high outputs can be use at the same time. Unfortunately I am getting a hum from main speakers hooked to Carver amp. Haven't checked out Carver but hook mains to reciever and hum is gone. For now I am going run interga till I get a chance to check out the carver. At least I know I can use pre out's and high outputs at the same time.

This niles is a nice piece and may be use ful down the road, switcher and build in 12 volt trigger. Looked at manual for interga and if I understand it correctly the pre out and high outs work at the same time unless mode switch is pressed and turns off pre outs. If true I can hook the carver to the main pre out and the surrounds would still have high power to surrounds. ( Will that give more power to surrounds? ) There are no gains on the amp, if above works hoping I can use interga's setting to adjust volume on carver. I will post my finding later today, if this doesn't work the niles should be the answer. Now I am thinking nice pre amp to go with Carver, does it ever end.😍😋😮😮

Sorry should have said level control and not volume control, Carver has none. Checked out the niles spk1 looks like the way to go. Still if the pre pro could run pre out and high power at the same time that might work, I will have to check an online manual.

Yes - no volume control on carver amp.

Like to listen to music mostly in 7.2 occasionally 2.2 channel. Thought the carver has dead but just discovered it still works! Would like run avr to center and surrounds and have Carver run mains while in 7.2 mode if possible. If not could I run speaker from avr 7.2 to all speakers including mains then another set of wires from Carver to mains. Would I need a switcher to disconnect one set of wires?

Just tried zone 2 line out to Carver, loud no volume control at avr. Got to assume lineout is high power and not a pre out.

Going to try zone 2 tonight will let you know what happens. Don't mind using the interga with pre outs, has some nice tuning features but it's older and doesn't have some of the more modern features. Still might use but can I run main speakers pre out and other 7.1 speakers off high power? (Surround speakers and center) If this would work I would only have 1 set of wires going to mains and not 2. Some times I like to listen to 2 channel for music most times 7.2.

Want to hook up a Carver m1.0t amp and my avr to chorusII speakers. Using an onkyo avr that does not have 7.0 pre outs does have zone 2 and 3 line out. ( is the line out a pre out?) I do have an older integra that does have 7.1 pre outs. My goal is to use Carver on mains and use avr to power other 7.0 speakers. Do I need some sort speaker selector thanks.

Looked at monoprice - smart switch 110 plug in 2 remote controlled 110 outlets. Should be able to use a single 110 volt light remote controlled outlet. (walmart, HD) Have some wall warts at home I can play with first to see if they will trigger all 4 speakers. Thanks for the suggestion!

If I understand correctly remote controlled 110 wall plug plugged into a 12 volt step down. Thought about trying something like that, can't find a remote controlled110 input to 12 out trigger. I will check monoprice.

What size are ports, they look small. Didn't Chris suggest something like 2 in by 9.5 inch.port?

Have 4 surround's there can be switch from bipolar to monopolar with a 6.8 to12volt trigger. Looking for a remote controlled 110 plugin the can sent out a strong enough voltagr to switch all 4 at once. Amazon has them just not sure if they have enough power to switch all 4 speakers. Owners manual is useless. Suggestions! Thanks!

Down the road sub amp with subsonic filter for freg. below 20k. Play with cutoff freq. at 40 - 60 hz. Been wanting to to do room conditioning for awhile, moving equipment onto centered f20 will allow this. Chris how would I go about installing acoustic material around horn mouth. Material on sides of horn mouth ( an acoustic channel around mouth ) or directly over mouth? Till I decide to build if I want to another f20 I could try my revel b15 centered on rear wall.

Do you have a spare set I could borrow to test that theory, I promise to give them back. (someday)

I ran an academy with my chorus I's and it wasn't bad just not what I was looking for. Build my own center with a kappa b15, k79 and k61 much better. Academy is a great speaker but there may be a better choice for your center, hersey maybe. Just finished eq'ing my chorus II's, treble, bass, sub and it makes a difference along with picking right listening mode for 5 or 7 .1 Re read where you order crites tweeters for your academy, should make a difference for front stage. If I remember right the academy has a k76 tweeter, same diaphragm as chorus but smaller magnet.

Very nice, interesting read and picked up a few new tricks. I PL'ed everything and had to use sandpaper to clean up joints, not fun. Thanks for posting it will help now and on my next build.

If you find it great but the pic alone helps alot, thanks!

Wow I love it, my f 20 is painted black. Casters and pics are giving my some idea's! ( I can steal) Is your build in the tech/mod section I would like to look at it, nice work!

Send the guy an e mail with no respond, just curious already have both 1's & II's. He does have a text number but I'am not a serious buyer. Guessing there sold or seller is just irresponsible.

That was my idea, f 20 centered and use it for equipment and tv. My equipment is racked on the long wall so it's hard to do any room treatment on that side. Been wanting to do room treatment for a while. Have a revel b15 I can use for rear fill if needed. Pete does your f 20 fill room or do you run another sub. This will be mostly for music.

I have my chorus II's snug in the corners and angle out at 45 degrees, imo they sound great. Room is 11 by 17 by 8 ft.Try toeing them in see how they sound,. Good luck! I moved the speakers around for over half an hour. To me 45 degree angle and tight in corners worked out best for me.

Thought about that but would have to build a speaker stand for one speaker. Do you think the output would be significantly better? May be worth the extra work. Maybe this winter I build a second one.(maybe)
