JTR Captivator - Page 8

You are over thinking this. That is plenty of power and if the run is <25', don't worrry about wire gauge. You need a male to female (that is what I linked) at the appropriate length. Run the EP4000's in bridged mode with one speakon from the bridged channel (usually Ch 1). The amp end is female and the Cap end is male. You could also use bananas if you have Jeff install those but why when speakons are so easy, cheap, durable and reliable.

Thanks,

They are (242 & 244) broad band absorption panels from GIK Acoustics. Their quality and price made DIY an unnecessary chore (IMO).

More power is always a good thing but a single should be fine. For me, one advantage to dual amps is that my Integra 80.1 Pre/Pro has dual discreet sub outs. My sub pairs are on oposite sides of the room so this allows me to run Audyssey room correction and set the distance and levels for the sub pairs individually.

If your captivators are not co-located, dual amps would allow you to take advantage of your AS-EQ1’s ability to do the same (but using one LFE input and two outputs).

You're right, the level distance settings reside in the Pre/Pro or AVR so you really need to upgrade your SSP .

You could always start with the single amp and if you feel the need for more power/spl, get the second ... and don't forget to upgrade the SSP .

OK... well it looks as though you are going for a 9.2 system and you have done some homework. I have not used Crown amps but I'm sure they are fine. Hopefully they are in a separate equipment room as they will likely generate some fan noise. So you’re thinking one amp for the mains, one for the heights or wides, one for the center and one each for each surround pair? If you run the sub amps channels in parallel mode (one channel for each sub) that will allow the 80.1 to see separate subs and it will set them accordingly. I wouldn’t worry about any additional subwoofer EQ as you can always add that later if needed.

I’d leave the growlers out for the moment as they are probably unnecessary and would really complicate the setup/install. The good news is the DHC 80.1 will make your setup easy. The on-board Audyssey MultEQ-XT will set the speaker crossovers (HP) and EQ your system setting levels and distance for all speakers and subs. You will need to adjust the crossovers post Audyssey as it tends to set these a little screwy at times. I would suggest the T8’s @ 80Hz and the S8’s @90Hz as a good starting point. Plan on running Audyssey a couple of times (if not more). There is an excellent Guide in the Audyssey Thread in the Amps/Processor section of this Forum. Read that first.

Position of the subs is crucial and you should do some reading up on that. This Harman white paper is info rich and a good guide but quite technical. There are many descriptions of the "Crawling for Bass” technique on the web and that will give you some ideas on best position for the subs.

You didn’t mention room dimension or size but you are creating a very powerful system that could fill a large space. It might be overkill for a small space but better too much. Room treatments is another thing to consider. The GIK Acoustics has good info on this topic and they will assist on the configuration of the room should you decide to go that way.

You also didn't mention a source player. If you aren't going HTPC I would suggest the OPPO BDP-83. It will handel just about any format and has been a great player for me. Bottom line is that you have chosen some good products and if you take some time to set them up properly you will be rewarded with a very high performance system. Have fun and report back as that is how we all learn.

Your CC1800 has a single speed fan and makes more noise than the CC2800 and CC4000 (I have the CC4000) which have dual variable speed fans and so run much quieter.
