Even better when the person you're excited for is only 10 min away. Coach, I volunteer to help you carry your 215s upstairs so I can hear them. biggrin.gif

if its for your 215RT's why not just spend the extra money and go with the XLs 2000's?

No Nate sold his 212's to BrentTHX, I should know because I lost out on buying them frown.gif ......LOL

I did have the 212's but they are long gone to BrentTHX a few months ago. I will be able to run them every way possible, with/without subs. If I decide to use them as full range L&R in my system, I've got a minidsp that can have the job done in 20 minutes, easy peazy.

Do not read this Carp ... tongue.gif


The thing about the 215RT's is the the sound quality and FR. Try and find another speaker that is -3db 18hz-24khz ... I've been looking and there aren't many if any. Of course the 228/212 and subs can get you there also but not for less cost and in my room, the LCR woofers do everything the OS's did only cleaner sounding. I ran through all of the Scuba Steve demos the other day and every one of them was as good or better than the OS/212 combo including the bass feasts FOTF, WOW, Hulk, HTTYD. Gun battles in Open Range and Book of Eli eek.gif! Not once did I think wow I miss the OS's.

Then, I put on some music and it's game over. The 215RT's trump anything I have heard ... cool.gif

When you reference the gun battles, do you feel it in your chest? That is the type of midbass I'm looking for. Like when I went to the indoor range with my son and we were shooting a .22 pistol and then some jack-hole in the lane next to us started shooting a hand cannon. Internal organ massaging.

That's what I would do, doesn't hurt to throw a little extra power at those monster 215RT's right.

I know what your talking about.. When I go to the range. I bring two of my Sigs. And my Deagle .50. I have a Sig 226 and 220. Shoot those all day. Now when I get to the Deagle, well that's a different story... smile.gif

Yea I took one shot of my buddies new Savage 300 WSM and dang that thing hit me hard! And I am no small dude either smile.gif There is a guy on youtube who shoots a 20mm canon that I believe is originally an anti vehicle gun from his hands. Of course holds it off to the side and it goes flying backward.

I reckon you're past the point of diminishing returns with the 2000's Rhed.

Bridged into 4Ω (1kHz) it's 1550W versus 2100W, a difference of 1.3dB. Will you notice the difference between 127dB and 128dB SPL with ear plugs in and hands clamped over the top? wink.gif

Nice jp.. Is that .223 or 5.56? Or you have the interchangeable upper? My friend who I go to the range with has the .460 and the .500. That is one wicked cal. My kids like to shoot the .22 LR all day. They can finish 1000 rounds in 2 hours..lol. I think my wife has a video of them in FB shooting at the range.

I probably trip the breakers anyway on a single 20 amp circuit. Before using all that power, no?

I know this is off topic... JP- Please invert the secondary mag on that coupler upright. You don't want to fumble around and flip the mag on a mag change. It's a simple drop and insert the same direction.

Rhed,

Have you had a chance to compare the crowns vs just a receiver? (a good receiver that is stable to 4 ohms)?

It'll be interesting to know if the 215s can be powered with just a receiver or not...

Can they? Yes. Is it the best idea to get the most out of the speaker? No. Even at near reference, you will want a little extra juice than an AVR can give it. Will it sound good loud, I am sure it will, but at the same time, you are flirting with power limitations, and assuming accurate specs on the amp section of the AVR with multiple channels driven, and I for one would certainly want a little extra in the tank.

(European models do not accept banana plugs.)

Yeah, this thread is all over the replace at times, but tell us what JTR speakers have you listened to?

How do they compare to Aiwa?

3 - JTR 228's LCR (game room)
2 - DIY Sound Group V-8 Coaxials (game room)
4 - PSA Triax's (game room)
2 - SVS SB13+'s (living room)
1 - SVS SB12-NSD (bedroom)

I knew you would know that! The coupler is not made for Pmags. It came with all my fab defense stuff and I had to shave a bunch of plastic off to make it all fit. Then I tightened too tight and barely cracked one side of the coupler. I have a second to modify smile.gif Thanks!

I actually agree with you re the gun pics. But your "questionable sound quality" statement shows an amazing level of ignorance. rolleyes.gif

What is an assault rifle? An AR stands for Armalite rifle from when they began. Assault is the human. Anyway off topic yes and I was hesitant but this is the JTR thread right? And what is questionable SQ? I have heard Legacy Focus SE's and preferred a lower level (not even Flagship) JTR to them. Subjective I know...

Apparently some people were offended by me posting a pic of a gun. I don't know why it is offensive. Nobody was offended by pics of all the hotrods a month ago. I had no intentions of making anybody so upset by a pic of another hobby I have. Again I had no intention and it will be soon removed as someone went cried to the mods that I was out of line. Not sure how, not like I pointed it at anyone lol! BTW it's unloaded cool.gif Oh and I am not an NRA member nor do I care to be. Don't even know how to sign up. Is it possible someone is not lumped in with other people because they have a gun? Just don't appreciate being insulted in PM's

When using high sensitivity speakers, it is best to scale the SNR spec to 1 watt since that is where you spend most of the time. The SNR is rated at 8 ohms at maximum power. If you see the number stay the same and power increase, like in the Crown XLS 1500-2500, then the more powerful the amp the noisier it is at 1 watt. The formula for SNR at 1 watt is 20 log ((sqrt(P*R)/2.82). Here are the XLS SNR at 1 watt:

XLS1000 - 73.64 dB
XLS1500 - 78.2 dB
XLS2000 - 77.23 dB
XLS2500 - 76.54 dB

dlbeck used 5 Crest CC series amps for all his JTR speakers in his new home theater, The Savoy. These have a higher SNR. For example, the CC2800 is rated at 595 watts at 8 ohms and at 1 watt has a SNR of 83.23. I was really impressed with how quiet the amps were and how much power they had. The CC2800 is available from an authorized distributor on ebay for under $550 shipped.

I've thought that one reason some might like lower sensitivity speakers better is that they require more power thus getting a higher SNR out of the amp.
