Now major question?

For my three JTR 215RT's

High pass filter at 18htz

Or

Crossover at 18htz and send to my Seaton SubMersives...

I would naturally think the crossover.

But someone tell me otherwise if I need to know something more.
Very cool that you can crossover that low using the mini. In my room the only hpf I tried that blended the ported speakers and sealed subs was a 12 db slope Butterworth. Do you have sealed subs? If you end up having problems blending you could try something like a 30 hz crossover too.

If so what range to start to roll off?

And how low at 20Khtz?



I was thinking 10db hot from 20htz - 40htz with a gradual roll off to flat at 150htz.
For me it depends on the content and my mood. Most of the time around 20 hot at 20 hz and I like it to level off somewhere between 150 and 200 hz.

I do not roll off the highs. I know that supposedly people like the sound more with rolled off highs but not me. I feel like people that preferred that must have had the bass flat. IMO with hot bass if anything the brain craves more treble but that's just my theory.

Because there are 4 presets, I will do one at

1. 5db high at 20htz
2. 10db high at 20htz
3. 15db high at 20htz
4. 20db high at 20htz



and switch depending on what type of music or movie...

I see some used for around half that, but man, it would still be fun to have

Who here has the miniDSP nanoAVR?

Can you try something for me...

I think you can route the LFE channel to every channel!!!

So if you had 7 215RT's you could route the LFE to all 7 I think. Can some one try it please!

Dgage has both, but I am not sure he is able to do much of anything with his system until Friday.

He will probably jump on here and comment regarding if that is possible.

Apparently Coach doesn't realize his sub system is setup in just this manner.

Take a look at the following guide, which has recently been updated. They just added "LFE Mgmt", which does exactly what you want...takes LFE signal from every channel and sends it to the LFE channel.

http://www.minidsp.com/applications/...ass-management

Another guide you should probably peruse for your NanoAVR playing is about AutoEQing with REW.

No... I want to know if it does what RMK is doing...

Aka routing the LFE channel to every other channel....


Not... routing low frequency of all speaker to the LFE channel.


Only if you have all full range speakers like JTR 215RT's

Well, RMK! is special so I'm sorry but you can't be like him.

Gotcha. Yes you can route the LFE to your mains. Take a look at the second picture in the following document. You can turn on LFE In for each of the speakers such as FL Out, FR Out, and CTR Out. So you'd turn on LFE In for each speaker column with the appropriate DB level. You will likely need to reduce the level as you can tell the LFE In signal is mixed in 10db hotter than the other signals.

I wanted the Powersoft too but I eventually talked myself back down to the much more sane and affodable choice with the Lab.

I did see some bench tests with the K6 and it tested very well against the older LG FP6000 and the Crown Itech.

RMK! I may soon be testing LFE to my three mains as well, and compare to LFE going to my Seatons.

Then I might try something crazy like LFE to mains and LFE to Seatons at the same time! Lol.

10 X 15" drivers enough? Lol...

I was in the theater cleaning yesterday and realized I will have 10 15s also. 12 15's if I get the 215rm. I told the guy setting my new door to set it good.

What would I need to do from 30 htz down to make sure the "Ported" JTR 215RT's and the "sealed" Seatons play nice together. As they will be getting the same signal and I don't want to run into cancellation.

Carp will tell you to put an analog HPF on the 215's as a digital one could cause some issues. This can be done with the very inexpensive behringer mic200, or any other device that can run analog filters low enough.

Captain Obvious here ... split the LFE signal and low pass the Submersive's.

Of course, why you "need" more than the 6 15" woofers in the 215RT's is another good question. Some around here like to drink out of firehoses.

Check out the Upper-midwest-summer GTG Thread as some seem to think even 2 215RT's have adequate bass.

May as well get two S2's while I'm at it as well!

I couldn't agree more.... 8-18's and the 6 - 15's in the 215's. Yet, I "think" I might need more....

With only 3 18" subs and 6 12", I'm feeling inferior. If I keep the 212s, I'll likely add some MBMs. And for subs I hope the 24" I have on the way will let me stop at 4 subs.
