May be ~1k.

I am not sure since these speakers take a 4ohm impedance, i really dont have any idea on how inexpensive/expensive the receivers are.

I'd just get this for half of that...Yamaha is the industry leader for long term reliability, and it's rated down to 2 ohms.

Relax, HT isn't rocket science, nor does it have to cost an arm and a leg---especially if you ignore the aforementioned vocal minority. And remember to smile...it's just a silly hobby, after all. :)

Oops, I forgot...you need 9 channels. I'd look at this Yamaha:

Denon X4300/X4400 is another 9/11 channel option.

Both Yamaha and Denon produce 140wats per channel but in the below link they say we need atleast 150 watts for T1s. Does it matter?

The difference in SPL potential between 140 and 150 watts is less than 1dB. Don't sweat 10 watts, especially if you intend to use subwoofers, which would further reduce the power demands on your ear-level speakers.

Please let us know when you get everything all hooked up. I'm pretty sure I am going to go with the Emotivas as well and I love getting all the information and opinions I can.

No replacement for cone area. Just say no to wimpy woofers. There is a reason why real theaters use speakers with 2 15s and a big horn. Also directivity matters.

Have you been in a HT with such speakers? I’ve just never felt like bookshelf units cut the mustard. Why are there so many options for diy with 12” and larger? Most of the guys building them don’t have huge rooms.

Horses for courses.

If you want huge boxes in a small room have at it.

Never felt the need myself especially when my front three with 7" drivers supplemented by a 15" sealed servo sub with its 1250watt RMS amp will peel the paint off my walls without making the 200 sq/ft den look like a recording studio.

My Dad back in the day had 15" Voice of the Theater Altecs commonly used back then in theaters.

Each speaker was the size of an office desk.

But then again he owned homes with large rooms.

sounds like your dad was a cool guy.

I have a servo sub as well, use it for music only in a small room. Love it, most accurate sounding sub I have had for music. Had it paired with various small bookshelf speakers, never happy, ended up with a set of 8" studio monitors with cabinets large enough for low tuning (I think 35 hz?). Finally sounds smooth. Part of my point was, there's a mentality that as long as the speakers can play to the crossover point, anything below that is a waste so let's use tiny woofers. I understand the theory but in practice, tends to either sound wimpy, have a dip somewhere, or you end up crossing the sub higher than you want and it is localizable.

Yes, in my main Home Theater room the system in my secondary room with 5.25 " main drivers and a center with 4" main drivers would sound "small" vs the 7" main drivers with 39hz I'm using now.

But for a small space my secondary system would sound just fine paired with a high quality sub.

Yeah, I'm sold on sealed servo subs after buying my first one in the eighties but I'm a tiny minority here on AVS.

Alright!! I hooked up all the Emotivas yesterday with the HSU VTF 15. I heard some music first without the subwoofer the T1 s had some decent bass and very clear instrument sounds. Next I played a Dolby surround 7.1 test and the effects were pretty clear. I am pretty satisfied at the moment but the only concern I have is the impedance on the receiver and speakers. The LCR are 4 ohms and rest are 6. I set the impedance on the receiver at 6 ohms for now and denon suggested that all speakers need to be having same impedance. See the attached settings that auto set produced. What should I set the impedance on the receiver and how loud can I play? @zorba @gajCA

Always leave the impedance setting on the receiver at 8ohm regardless of what the manual says. All that switch does is cut the output of the receiver. Play it as loud as you want short of the speakers distorting. If the load is too taxing the receiver will go into protection mode and let you know you need to back off a bit.

And turn the gain down the sub a notch and rerun Audyssey. You want the sub level between -5 and -8 ish so you have some room to adjust the level up a bit post Audyssey.

Won’t 8 ohms harm the speakers where they are just 4/6 ohms?

No. The switch is to protect the receiver, not the speakers, and it doesn't really do anything to protect the receiver other than limiting its output.

Thanks for the link. Both Emotiva and Denon scared the hell out me saying you should be having matching impedance on receiver and speakers.

Any regrets? Any thing you don't like about them? I was thinking about getting a denon receiver as well with the Emotivas.

good to know on the receiver impedance setting, I didn't know that. I am running speakers whose DCR is about 3 so prob a little under 4 impedance. I think it makes a big difference how hard you run the speakers and how they are crossed over. As far as being matched, always ok to run speakers with a higher impedance, that's an easier load on the amp.

gajCA, Back on the Rythmic Servo Sub (sorry off topic), I tried it for HT and the sound was quality, but it didn't take much for me to push it into limits. Kinda felt like I was misusing or abusing a high quality unit. Multiples would have helped but for the nature of HT I'd rather use something with greater excursion and more headroom. I think mine (15") is an older unit than yours so maybe less capable. Smaller rooms/conservative levels or combo music/HT I can see the latest/larger ones being good though.

Others have already answered; leave the impedance on its normal setting as per this article.

https://www.audioholics.com/audio-am...ector-switch-1

Familiarize yourself with the different EQ settings that sub offers with one port plugged, two ports plugged or both open etc. to find the one that produces the best sound in your room as depending on placement the max excursion setting my be too much.

Nope!! They sound good to me. I also have listened to Klipsch Reference series but these speakers are neutral and the quality is just superb.

Did you mean 9 0 clock? I have turned down the sub but didn’t have any success getting in that range. I got a +1.5db reading. Also should I be level matching all the speakers with spl meter? If that’s true then when audessey set my LCR to -6 I had to go all the way up to 12db to match the recommended 75db per channel. I am not sure what I am doing wrong. With the previously attached picture of sub I have one port plugged in.

I might have got that backwards. You want the sub reading between -5 and -8; wherever you need to set the volume/gain (up or down) to get that. Audyssey is level matching the sub and speakers and you want them level matched such there there is a minus reading in the sub to give you headroom to boost the sub a bit post Audyssey.

I got the sub levels at-least till -0.5 now. So does this mean when we do audessey we don’t need to set the levels with spl meter?

That is what Audyssey is doing when its sets the trim levels; level matching the speakers at the MLP.

Perfect! I have made it to -5.5 and adjusted to what suits my listening levels and really happy now with the set up. Clean bass and dialogue!!! Thanks all who helped me for this set up. I really love it and it’s movie time now.
