As more and more ppl buying these speakers, i thought that there should be a centralized thread to post pics, comments, setup.

Good idea. I'm a happy customer, Triple 12LF's for LCR driven by Emotiva XPA-5 with B&W DM602s3 as rears and a Paradigm PW2100 sub. Epson 6500ub PJ, Onkyo 886 pre/pro, Cinetension2 134" screen and Oppo BR player. My system ROCKS and it is not finished. Need window treatments and an acoustical panel or two.

I'm still playing around with the Audssey settings and the crossover settings for the JTR's.

I have my 2010 Triple 8's. Great build & sound quality, small size, Dynamic, efficient, great clarity/resolution in midrange and highs, neutral sound. What I need now is a more powerful amp & more powerful sub(s) to go with them.

My Amp is pretty similar to the Emotiva XPA-5 see here you seem to be happy with having enough power for the 12LF's?

Tom,
What amp are you using? What do you feel is lacking with the current amp?

I'm probably going to go all JTR for my HT (5.1) but theres been one nagging question left. I currently have a Denon 2809CI that I just got that is rated at 115w (7.1) into 8 ohms and is not rated for 4 ohms, though from other posts I here that this receiver doesn't have a problem driving 4 ohm speakers. Considering the room is no more than 2,500 cubic feet (sitting maybe 9-12 feet away from the speakers)and these speakers have such high sensitivities (T8s). Do you think getting an additional amp and using the denon as a pre would even be significant? Sure I could probably turn it up a little louder but wouldn't the denon be plenty?

Of course I would get the appropriate amp for the captivator.

If the Denon will drive them ok then at what levels do you want to listen at?
You will get 98dB's at 1m (3.33 FT) @1watt. If you want say 105dB's at 12ft then you will need just over 64 watts of power. (64 watts will give you 116dB's @ 3.33ft less 12dB's for 12ft away).

Also remember that the Denon is rated at 115 watts doesn't mean it will deliver that all channels driven at once.
My advise get an amp.

I'm using a receiver. A Yamaha RX-V2600 which is 130wpc into 8 ohms. I was looking at going to something like 350wpc into 4 ohms. I'm glad the speakers are nice and efficient.

I'll bet the d-sonic 525 x 3 would be incredible with those speakers.
I love mine with my JBL Pro's. You could also find a nice 3 channel 200 watt (honest) used amp...like Acurus or Parasound. really ggod values.

Whenever you play loud near to amp max power output, you will hear higher distortion from the amp. So it's advisable to get an amp with higher headroom so that it can play loud and clean.

The d-sonic amps are really nice looking amps, however, way over my budget.

Got my LCR 2010 8s today. Had the 09 versions previously. It's been a while since I've listened to the 09s AND I had over $1000 of upgrades done to my EAD pre/pro too.......what I'm hearing is excellent but I'm sure some is due to the upgrades and some to the speakers. The biggest difference that strikes me compared to what I remember of the 09 8s is a much warmer and rounded sounding midrange....so the midrange character definitely seems more of a presence than the previous versions. I have a good bit of hum with no signal present....can here it from 3-4 feet away but it does not affect the sound. Just using a 2 channel system right now with an 8" Mirage powered sub, modded EAD 8800 pre/pro, Wyred4Sound ST-250, and Oppo 970HD.

Extremely pleased and can't wait to get the theater set up. Jeff installed some inserts for me like before so I slickly have these mounted on some M&K ST1 stands and tilt brackets.

To get rid of that hum just use a 3 prong to 2 prong adapter on the Wyred amp. That's how I got rid of my hum.

I would be careful of floating the ground on a digital amp.

Chances are the hum is from a ground problem with cable or sat wiring.

My bad....wrong choice of word. It's not a hum and I've never had a ground problem at my place...several years and several systems. It's the hiss coming from the speakers when no signal is present but they are receiving power. All of my speakers have done this to some degree. Again it's not a problem. I think because of their sensitivity, my previous "coming out of standby" volume setting was quite a bit louder than with my previous speakers therefore the hiss was louder.......I think I just need to turn down my master volume a bit and save it so it powers on quieter.

I'm going to do some serious listening over the weekend and I'll post my thoughts Sunday night or Monday. I mainly listen to blues and hard rock/metal, but I'll be sure to spin a variety. My poor little 8" Mirage sub is going to get abused but it's hangin in there and I'm quite impressed for the money. I WILL be purchasing a couple of big dogs though when I get a theater set up.

High effeciency speakers will definitely make noticable whatever hiss, hum, or other problem that might have gone under the radar before. There is a lot I have to chase down in my own system.

I'm sure that's what it is gpmbc........I mean we're talking 10+dBs more sensitivity than any speaker I've previously owned. When I powered on my pre/pro, my default master volume was -40 and it was just a lot louder than with previous speakers and that's why the hiss was more present......I just need to turn my master volume to an even lower setting. When the music starts..it's all gravy!

Sounds good Kevin! It can be nerve racking at times. Now I'm looking into balanced connectors, dedicated lines, and the list goes to try and get silent or close to background. These are areas which I have known for a long time offer benefit but wasn't an issue with low sensitivity speakers.

I'm building a home theatre right now and will be going with an AT screen. Would the JTR triple 12ht's be an appropriate choice? If I place them behind the screen how much room would they require? I would probably use thee of them for the front but am unsure of what to use for the rear channels. What amps and subs play nice with these?

Thanks

So I've had a little more time to listen but not much...other things keeping me too busy. The midrange of the 2010 Trip8 is the star for me, that and the ability to play loud and clear. I was also surprised at how well they disappear for pretty large boxes. What I haven't listened to yet is some softer, delicate music with female voices(Norah Jones, Krall, etc.)..that's next up when I get a chance. These speakers sound so good with music that I'm sure they'll excell at movies...which some of you are probably using them for right now...damn u It will be a while for me yet.

Congrats and thanks to Jeff for a fine product! Also, I would like to hear other's opinions too...I know people have and are taking delivery now.

RMK, I wanna hear your thoughts on the 8s, and when you have the Caps in the mix too!

I figured that would be the case with an all new driver, lighter cone, and no more than 2mm of movement due to the crossover. Is the midbass anemic in comparison?

No, no...plenty of midbass too, as you would expect with two 8"ers. Not muddy or mushy at all in my system. I have them crossed at 80Hz with a powered 8" Mirage S8 subwoofer and the combo works great together. My trip8s are about 7 feet apart, slightly toed in and angled upward so the center comp. driver is firing at roughly ear level. They are almost 2 feet out from the back wall, and a little under 3 feet from each side wall.

My EAD 8800 pre/pro has about $1,500 in mods from Noble Electronics so it has a lot going for it as a DAC so I use the digital connection from an Oppo 970HD. Power via a Wyred4sound ST-250 Ice amp. All of this gear is meant to go into a dedicated theater....just waiting for my house to sell. Denon 3800 blu player will replace the Oppo in the theater....for now it is just hooked up to my plasma using the tv speakers. And depending on how RMK's combination of Spuds and Captivators go, that may be the direction I head for woofage when the time comes.

Any progress with the amp swap and Triple 12LF vs 888 comparison?

Working on the room but did take some time to setup and listen to the T8's (as surrounds) for a few friends last night and the results were fantastic. I'm finishing up the wall patching today and will do some A/Bing tonight.
