Receiver for Proficient Audio Systems C620 6.5-Inch

post #1 of 12
Thread Starter 
New house. Builder installed these in ceilings: Proficient Audio Systems C620 6.5-Inch. Specs here:
Main Features
· Ceiling speakers with 6 1/2" polypropylene woofers and 1" silk pivoting tweeters.
All Features
· Power Handling: 100 watts
· Frequency Response: 36Hz - 20 kHz
· Impedance: 8 ohms
· Sensitivity: 91dB 1W/1m
· Diameter x Depth: 9 1/4" x 3 5/8"
· Ceiling Cut Out: 8 1/4"

There are 5 for the 5.1 and two sets of 2 in the main floor and in the basement (total of 9 speakers in the house).

Looking for a receiver to play the 5.1 plus the two other zones. Any suggestions?

Forgot to mention that I'll be buying on/near Black Friday and that my budget is $1200 (but I'd like to stay below $900).

These speakers were installed in my house also and am currently looking for a combination multizone surround and audio system. I have (2) sets of Proficient C620s pre-installed with volume control in a great room and study and a set of Proficient AW520 with volume control on a porch. All the speakers are connected to a terminal block in media closet and are all on 1 zone. I also plan to setup a 5.1 surround system in great room . So, I only need 2 zones... (1) 5.1 HTS and another audio only. Most of my equipment has previously been Sony ES, but I am also looking at Yamaha Adventage line. To do 3 zones, you will be limited to 9.2 channel higher end units. Yamaha 2000 series or higher is good example (~$1500). Any zone 3 capacity below that will likely require an additional pre-amp. 2-zones easily get you to your price range, but I don't think you will be able to do $900-1200 unless you get one of these higher end 9.2 channels on discount on outgoing unit, etc.

What about if I got a separate amp and kept all the whole-home speakers on the same source? Is that doable? If so how does that get wired?

How is the wiring terminated?

All speakers wired to one pair of wires?

Every speaker has its own pair of wires?


Something else?

Ok... here is my setup and future interest in more detail. Each speaker set (Proficient Audio; 2-C620s, 1-AW520) is wired to a volume control switch (Russound ALTx-20D). Then, each volume control switch is wired into a six speaker distribution terminal block (OnQ, not sure about model #). Then the terminal block goes out to the source (i.e. old Sony Audio Receiver). There are 4 wires coming from each set of speakers (i.e left pos & neg, right pos & neg) and 4 wires going to the source (i.e left pos & neg, right pos & neg) . The volume control switches handle the impedance matching of the speakers. If you don't have volume control switches, there are distribution terminal blocks that can provide that. Although this simplifies the setup to one zone, note that the power is now even divided between the speakers and they all play the same audio source. The specific receivers to add 5.1 HT that I am considering are from the Sony ES line (1800ES, 2800ES) and the Yamaha Adventage line (730, 830, 1030). The goal would be to retire the old receiver and have one new unit that does it all (Zone 1 Audio/Video, Zone 2 Audio Only).

This is the same set up I have except I don't know the manufacturer of the volume control. I'll have to double check the wiring configuration, but right now the whole house converges to one spot with coiled wires coming out if the wall (no terminations yet).

I am not exactly sure but this looks just like my 6 speaker distribution model here (OnQ Model #364454-01): http://www.legrand.us/onq/audio-video/audio-distribution/impedance-match/364454-01.aspx#.Uj4MKBZX_zI
Looks like they are available on eBay for ~$55. My wires also all come to a central location in the house. A media closet that has a panel on the wall where all my media (i.e. cable tv, internet router, spaker wires, alarm, etc) are located. The speaker distribution box sits behind the metal wall panel box (similar to a main fuse box, etc). To access the wiring, etc 4 screws and a cover are removed. The 4 wires to the receiver are routed through the wall to a wall mounted shelf where the receiver sits. At first I wasn't so sure about having all the speakers on one zone but now I am convinced it is the best way to go. I just turn down volume in rooms where you don't want music. Only having two zones will also give you a lot more options in receiver especially in your price range. The list price on the Sony ES1800 and the Yamaha Adventage 730 in the $600s all way up to Sony ES2800 or Yamaha Adventage 1030 both with list around $1000. There are folks on the forums that also really like Denon and Onkyo but I don't have any experience with those.

Anyone else with experience with these speakers? Anyone else recommend a receiver for this situation?

one more thing that i forgot about it. there is not much information about the Proficient Audio line online. however, after doing my initial research, i discovered that the speakers are manufactured by Speakercraft for Proficient to sale new house installers. if that is correct then the Speakercraft equivalent to the C620 model is the CRS6 One. you can find more info about it here:

OK..
Lets start with some basics..
Proficient Audio is part of the Nortek corporation, who also owns Elan, Geffen, Panamax, Xantech, Niles, Sunfire and SpeakerCraft. SpeakerCraft & Proficient Audio share common engineering/development resources so often there are multiple versions of similar products. SpeakerCraft invented the in-wall loudspeaker and have even built for certain brands such as JBL and Polk. Their products are targeted to the installing dealers, specialists and distributors in the CEDIA channels. Now to your system questions:
1. What type of volume controls were installed? L-pads or stepped transformer attenuators?
Note this is relevant to their power output handling capability, the stepped attenuators is what you want.
2. Regarding the loudspeakers (2) pairs and (1) pair in separate zones
I would recommend a separate amplifier for these rather than using the amplifier within an AVR. SpeakerCraft has a (6) channel multi-zone amplifier, model #Vital 170V that would work fine.
3. AVR choice
For the AVR get one that has a Zone 2 & 3 line outputs, this way you can operate each zone independently from each and the main system.

Note that what we are recommending may seem overkill, but I can tell you after doing AV installs for over 20 years don't cut $ install solid, robust hardware. If not 2 or 3 years later you will replacing the cheaper stuff...

Just my $0.05... 👍😉
