How much of a difference does the amount of space from the wall make with these? Is the room to breath thing a myth

Well I set the spk levels on my Integra with my radio shack meter & I get 80 db at 11ft from the 12s & had to set the level at -12 for the 3 12s,so I set my souround spks to 80db also to balance my system.

Does anyone know what frequency the low level test tone on Onkyo receivers play at. Maybe 40Hz??? In order to calibrate your sub in your HT with your receiver's test tones and an SPL meter you would need to know the frequency being played. Is that right?

At this point, I don't have a separate eq for my subs and was just looking to verify my subs levels

Not too familiar with the Onkyo's but I'd assume it's pink noise (as opposed to a single frequency) with the chosen crossover applied

As long as the SPL meter is set to as full range as it goes I believe that the tones are designed to use with an SPL meter. For example, my measurments with a Radioshack SPL meter are usually within a db of what Audyssey measures on my Onkyo.

That sounds reasonable with that setup. Now you know that the main volume is 5 db higher than what it reads. You could consider seting the input levels for your sources 5 db lower than you normally would so your volume will be at reference level.

Where is the full range setting on the meter. My meter has a response setting (slow), and a weighting setting (set to A right now). And then you set the db range to either 80 or 70 and begin calibrating. The problem I am getting is that when I switch to the low level test tone nothing is reading in that range unless I turn the level up significantly (and at this point the sub is shaking the room). I must be making some stupid mistake.

You want the slow setting and C weighting. I believe that C weighting is as close full range as you can get on the Radioshack meter. I put mine on a tripod in the primary listening position and use the 80 db scale. It does not sound that loud at 75 db. I think the C weighting may do the trick. I believe A weighting preferentially tests for sound in the center of the audible frequency spectrum ignoring the extremes such as below 80 hz.

Sounds like a winner. I will try that out. I knew it would be something stupid

I think that main reason that some speakers need room to breathe is that they are rear ported. Other issues involve avoiding reflections off of the walls and creating unwanted vibration noises in the walls. All of the JTR speakers are front ported which eliminates the rear porting issue. The other issues are not specific to JTR's but can be dealt with using acoustic treatment if the placement is such that reflections cause problems. If there are vibration issues that cause a problem with direct contact, these can be helped by putting foam or something similar between the speaker and the wall. RMK! has his T8 and Slanted 8 surrounds directly on the wall surrounded by acoustic panels so I don't think there is a problem putting them near a wall.

I think you are referring to the main volume level. What I am referring to is a feature in your Integra called Intellivolume (or something like that) that allows you to adjust the input volume of various sources so that when you switch from a Blu-Ray to a CD in a dedicated player the volume does not change by much. You can set these levels using test signals on discs. You can use this feature to set the volume 5 db lower on each input so your listening (master) volume level will be accurate.

How would you compare Slanted 8's to Paradigm Studio 60 v3's for surrounds with triple 8's in the front?

I have the paradigms now and can't think of another speaker that I can get for a decent price that can compare to them and they are pretty efficient. The slanted 8's might provide a better match but are they as good of a speaker overall compared to the 60's?

I can't comment with comparisons, but what about using the 60's for now and save up for a while and get the matching JTR's later. Do you have another zone or room that you could use the Paradigms in after you get some slant 8's or whatever? It doesn't sound like you want to part with them and I don't blame you. Of course, I've been trying to kill the electronics hoarder in me and sell some of my gear in the classifieds, but it can be hard to let go sometimes

lol. i've got 3 pairs of speakers, an RS1, two amps, a preamp and a vp in the "to sell" room off the HT. I'll be adding another 5 speakers to the collection as soon as the T8's and slant 8's get here...

Good morning gentlemen...

I hosted a G2G at my home yesterday that featured my full JTR speaker compliment. Jeff was kind enough to attend and help me set everything up. I'm pretty much where I want to be audio wise (outside of some additional bass EQ and rrom treatments) and the Captivator subs (along with the Quintuples) are some very interesting new products from JTR.

It is really cool to support small US manufacturers who put so much of their blood and sweat into making something that sounds great at a reasonable price.

Are the Captivators a passive or active sub.

What amps are you using with them? Are you using any outboard EQ for them?

There is a Captivator Thread in the Subwoofer section that would be a better place for this discussion.

2010's are suppose to be much clearer and new drivers.

I am sorry. I wasn't clear enough. Does anyone know visually how to tell the difference between the two? If there are any physical differences. Or does the label state 2009 or 2010 version?

The woofers are different 2009 vs 2010 and you can see it. The cabinet in the front is also different on the 2010. The 2010 is about 10lbs lighter and it is smaller than the 2009 version. The 2009 version has it's own enclosure for the coax driver, the 2010 no longer is required to have it because of the new coax drivers sealed back design.

I don't actually think the difference in sound quality is very big, from what I've read. I think the 2010's are a bit more sensitive and can handle more power, but, for normal listening, I don't get the impression the sound quality is going to be much improved.
