Thanks for the info
While I will get two FV18 eventually, it is nice to know!

It should not turn red. The behavior of A370 and H600 analog amps is when protection circuit kicks in, the light will go out. Most customers think it is power issue and proceed to unplug the power. In fact, sliding the power switch to OFF resets the protection. This method of code reset also applies to HX series amps.

Oops, thanks Brian. Obviously I have not had to deal with it since my initial testing all those years ago, and have not had to get behind them because they just sit there doing their job without fuss.

I believe m-10 is a standard size for speaker treads. From the reply you got, from @enricoclaudio.
Here's a link, where I got my Custom Made Outriggers;
https://soundocity.com/product-category/tips/

The man is on retirement, and do custom work as a side hobby and small business.
His craftsmanship is Outstanding, and many choices to choose from.
For the tips, I went with two different colors. One color for the Tip, one other one for the main body of the brass cone (see my Theater page, attach to my signature. For pictures).
And since all is work, is custom made. You can request a m-10 tread.

Thanks, these look like a good value. I'm probably set on Mapleshade Heavyfeet because those did wonders for my towers, but these look like a great alternative. It'll be a while before I actually buy the feet so I have plenty of time to decide. Will be enjoying the Rythmiks with stock feet in the meantime.

How many in here running crossovers higher than 80hz? I bumped mine up to 90hz this past weekend and ran some sweeps. Just had to add a couple ft to the sub distance and it cleaned it up nice around the crossover point. Didnt notice a ton of difference, but thought it would take a little more workload off my LCR. Probably more beneficial to my Sierra 2's than anything.

I was thinking about trying 100hz or higher next time I get an inkling to bust out the umik. I don’t think I have to worry about localization as all my gear is along the front wall by the L/C/R. Just would like to prevent deep voices from getting routed to the subs. Not sure what frequency that typically would be.

I use the lfe input on the subs.

Sweet, I will bump it up a bit more. Bad thing is my avr only has a global crossover.

I tried getting in on a Denon 4400 from Frys for 599, but it’s a difficult thing to do with that place when it comes to getting one shipped.

Going from 80 to 90 is very subtle; going to 100 is a little more noticeable. Whatever it takes to fill in a dip in that region.

If you're worried about the sub affecting voices, flip the switch on the amp to 80/24. It will start to roll off close to 90 but it will be fine and will cut a lot of >200Hz sounds from the sub. Don't forget to recalibrate with that setting. If it's still an issue, use the Line-In instead of LFE, if you have it. I tend to benefit when my XO is 100 and those running higher may as well.

I am using a 100hz crossover with no localization whatsoever. The MLP is roughly 9-10 ft from the subs (FV15HP's).

Excellent! I think I will bump it up to 100hz and run a sweep to see how it looks and adjust the sub distance as necessary.

I did some minor eq adjustments on my minidsp and need to recheck my sub level anyways and make sure it is still at 75db. Might as well knock out both things at the same time while everything is hooked up.

After this I am packing up the umik and REW for a while and just start listening to my system instead of tweaking it all the time. Famous last words. lol

The amplifier was designed for internal use so it's highly unlikely there would be any additional lifecycle if it were external instead. Performance variation would be zero; it's designed to supply X number of watts, something unchanged by it's physical mounting location.

If you take yourself too seriously expect me to do the exact opposite...

This is hard to avoid if the subs are near-ish, but you can mitigate a lot of it by using the Line-In and/or the 80/24 slope switch. Best results are obtained if your speakers can pick up the slack in the midbass.

All depend how low the speaker can play, more on my reply to the OP.

Just took a look at the specifications of your speaker;
46Hz - 38kHz ± 3dB

While the crossover is not a brick, and lower frequencies will still be played. But at a lesser loudness, setting your crossover higher. Normally yield better results for your midbass, at higher volume of play. That said, while my towers can play a little lower. I set them to 80Hz, and think you should also be fine with Sierra 2 to be also set at 80Hz. Since a good sub, will take of the rest and do what it is design for. If your lower frequencies were higher (like 60-70Hz), a higher crossover point would be required. Not case for your speakers

for me an dozens of rew, it was all about xover freq smoothness...90 and 100 gave better results but I didnt like sub location sound....this led to countless attempts with different front speaker toe in angles which finally resulted in best at 80hz. pointbeing fronts determine alot.

Here is a crappy pic of my laptop, I’m not on my laptop right now to get a proper pic. Snapped this one last week when I was tinkering.

This is with a 90hz crossover. I am in a 10k + cubic foot open floor plan with a big open staircase on one side of the room, hallway, dining room, kitchen, office, etc. I’m ok with the one null as I’m limited with placement options, WAF.

Blue line is pretty flat with 3 filters from REW imported into my MiniDSP. The other is with +6 dB boost via the sub trim in my avr. I run the subs in 12 hz tune, 12hz extension and mid damping right now. These subs rock this big space, big time. Loud and alot of TR.

Exactly - you tune your crossover for your overall frequency response. If that means raising the crossover frequency, then go for it. But if that brings in upper frequencies that don't sound good, try one of the tweaks I mentioned. Fixed it for me by bringing down the top end of the sub from 300Hz to about 200Hz. No problem with 100Hz crossover and rear sub is 4 feet behind my head. Sticking with LFE-in and the standard 12Hz slope did not sound good with a 100Hz crossover even with subs further away. YMMV.

The family and I had a lovely trip to Australia in April.


However, a couple things displeased me a bit lately...
First, Ferrari is not doing well in F1, and every time I look at my old Testarossa I like Mercedes less
Well, they did better job than Ferrari over the past few years, and Seb is no Schumi!

Second, lately my FV25 behaved different, since about 4 to 5 months, the green light will flash/blink twice, sometime after watched a film, and sometimes even without use it for a few days (I was just checking it from time to time since I experienced green light flash/blink). Why it happened?
Thank you very much for your time, should someone can educate me on the matter!

As I was ready to get another FV25 or two FV18, and now I am thinking something local in Europe.

Thank you all.

Just tried 100 Hz crossover and it sounds much better. But I do not know what does it change on subwoofer position on AVR. I think I have to add a couple of feet for phase adjustment at crossover frequency.

Do someone know a definitive way to fix phase with the distance trick on AVR ? When are you sure the setting is good ? I tried by ear ...

With 80 Hz sub is set at 11 feet (real distance) at 100 Hz sub seem to sound better at 12 feet ...

Enrico and Brian do you have a method for phase with AVR ? Just by ear or do you have something more "scientific" ?

With 80 Hz sub is set at 11 feet (real distance) at 100 Hz sub seem to sound better at 12 feet ...

Enrico and Brian do you have a method for phase with AVR ? Just by ear or do you have something more "scientific" ?
This is how I integrated my subs: https://www.avsforum.com/forum/155-d...ow-thread.html

If your AVR has something like Audyssey, it will usually handle phase/distance well, as long as you started calibration with the knob on your sub at zero.

If you want the "scientific" method, you would use a MiniDSP UMIK-1, optionally calibrated by Cross Spectrum Labs for increased accuracy, and software like Room EQ Wizard to adjust sub distance to smooth out speaker/sub integration (after room correction).

Funny you guys bring 100hz crossover up.


Ever since I got my G25HP blending with my L22, I was also experimenting with the crossover point on my KEF LS50 's.


Weeks and many hours of using REW, a Spectrum Labs calibrated UMIK-1, a MINIDSP HD, I got the smoothest frequency response at 100Hz, and 12dB/Octave crossover slope within my AV processor this yesterday.


I'm using the LFE inputs on both the G25HP, and L22 so far. I haven't tried the line in.


I really wanted an 80Hz crossover, but using REW showed me that was not the way to go in my living room.


I'm actually contemplating using the line in inputs on the subs to see if I can get the subs response smoother, but since I have a MINIDSP HD, I think the LFE input is the way to go. What experience do you guys have blending RYTHMIK subs with a MINIDSP HD, and line in vs LFE?

Can you post a rew graph? I want to see what your crossover region looks like. Curious is all. Mine is kinda up and down but not a sharp cliff like I’ve seen before.

Sure, what exactly should I measure? I can post up after I come back home.

Just the standard channel 3 sweep (center plus sub), or whatever speaker(s) you are blending in at the crossover.

Just curious how smooth it is.
