It depends. The main difference between the A370PEQ and A370PEQ3 amp is that PEQ3 has LFE IN and LINE IN inputs. The PEQ has LINE IN and HPF OUT. The HPF OUT is fixed at 80Hz. So if you plan to run your speakers full range and crossover the subwoofer at the natural roll off point of your speakers or if you have an outboard DSP, then go with PEQ3. If you plan to use the HPF OUT and run your speakers at 80Hz, then go with PEQ amp.

Dual subs > single sub

I still have one of my F18's behind(as in practically touching) the mlp, and while I don't like the vibrating chair affect with normal music, it's cool with this song. I guess I'll have to try the other super bass tracks I have before moving it.

Edit: Ok, I'm liking the effect so far, although I've activated a new really annoying room mode. I'm already thinking of having two bass setups, with the f18's away from the chair for most music, and two of my currently unused lesser subwoofers(added to the f18's) behind my chair for movies and bass music. At the rate I move, I should have that setup by this time in 2020.

You could plug the two currently unused subs behind your chair into smart switches that work with an echo dot and then you could have them on or off by saying “Alexa, turn off the movie subs”

I have my dual FV15HPs in smart plugs and the amp that powers my tactile transducers in a smart plug. So, when my wife (who hates bass) is watching something and I’m not, Ive told her she can just say “Alexa, turn off the subs” and the group I made in the Alexa app contains the three things (two sub plugs and amp plug). Away goes the bass and she’s happy with her dead sounding TV.

Hahaha, hey it was that or bye bye subs. With the twins joining the family 5 months ago any rumbling sounds equaled our babies going deaf in the eyes of my wife. The only good sub, is a dead sub as she puts it (reference anyone?)

Using dollies under subs

Being of the older persuasion and with a pitiless back (and a few other health issues), I built a pair of dollies that will accommodate a couple of F12s, which I am considering pretty intensely. If I'm going to move them about from time to time, this will be the only feasible way for me. No WAF is involved.

Sound-wise, this probably isn't a good thing, I know. How might a sub-on-a-dolly's output be adversely affected?

Also, this:
  • This is for music only. No HT, no movies, no TV.
  • My mains are pretty heavy (for me) and they're also on dollies, which has worked out OK.
  • Not planning on using any room correction technology, just going to adjust manually.

Thanks!

How far do you have to move them? If you mean just around the room many use sliders on carpet or ones for hardwood if you have that. They slide really easy then. You can leave them sitting on the sliders so you don't have to lift them on and off.

Anybody else have the G25HP’s? I’ve seen a couple people post about them but been quiet for awhile.

On another note, my FV18 continues to impress. All around awesome sub for music and movies. Crazy how dynamic these subs are with movies. Can go from subtle, to on the Richter scale with crazy deep hard hitting extremely low distortion non boomy bass. Wow, that was quite the ramble. With music on my Sierra 2’s it blends seamlessly and makes it seem as if the little bookshelf’s are throwing out all that sound on their own.

Cool stuff!

Just curious, didn't a surge or such plugs limit the power the subs get? Somewhere I read about removing the famous iNukes from power strips and such because limits current.

Funny you ask. I first tried a couple of dimming plugs and even at “100% brightness” the sub wouldn’t turn on. In my case it was the on/off smart plugs that work. I use Wemo insight plugs which also show me the usage.

Does any size of vented rythmik sub can be mix. My lvx12 seems enough after tweaking for some times. Now start saving $$ for the next sub.

I ended up selling all my other subs and keeping the 2 G25HP's I have. I have continued to tweak and set them trying to extrapolate every ounce of performance out of them. They continue to impress me every single day. I haven't really pushed them anywhere near their limits, but I am alone all weekend so I will have to dig out some movies and give it a run! For music, I have not heard their equal (keep in mind I had 2 F113 fathoms for years).

This was posted today by Aaron in our FB page:

"Thank you for the G25HP! It completely destroys my SVS PB13 Ultra. Now, I understand the two subs are almost incomparable. Reason that I did was because they are/were Similar in price, granted my Ultra is five years old, and I really have nothing else to compare to. Very tight, very accurate. It wins at all frequencies and the output difference is unreal👍👍. Enjoying my Tekton Double Impacts even more!"

Rule of thumb is mix ported subs of similar tuning frequency and roll-off slope. For instance, one cannot mix one ported sub without rumble filter with another ported sub with rumble filter. If in doubt, check the phase plot on our subs.


Using multiple subs can create more even frequency response. But that also means the max SPL increase is not as great as co-locate two subs.


Right now you have right corner that produces slightly less room gain below 30hz, you can compensate that with higher sub level as long as the green LED light does not flash in the back (this function is only available for our Hypex module based amps).


The left corner seems to produce a broad null. So even if you get a second sub, that location will not be first choice. When mixing multiple subs, one needs to find efficient locations to start with.

Got you. But so if ever i will get another sub Im only limited to another lvx12 or the fvx15 with the same kind of amp as lvx12.One more thing, right now it was connected on lfe (yellow input).Do i gain some signal if split it and connect to red and white rca input.

^^^ Even with C you'll still need to compensate for the weighting curve below 30 Hz.

"A" weighting roll off around 500Hz. You would need a C Weighting SPL meter to check on subwoofer response, and even that is not accurate because C weighting roll off at 50Hz. Best is getting a calibrated mic and measure with REW.

When I was measuring subwoofer peaks during BD movies I used the spl meter tool in REW with my UMIK-1 set to z weighting and fast response with spl logger. Works quite well, as z is unweighted like REW sweeps. I think I never listened past 90dB-95dB peaks back when I was checking this stuff... might have changed now.

I come in here every so often to check to see if there is anything new that would be make me want to upgrade my dual F25's that I got in 2016. I'm not interested in ported, so thankfully there hasn't been anything new available yet to tempt me into an unnecessary (but fun) upgrade. Any word on when the F28 or anything else non-ported that will overcome the F25 might be happening?
