Never Heard Anything Like This.. | Rythmik G25HP Subwoofer

[@nonametofame]

Using REW and being able to measure what the bass frequencies are actually doing in your room was the biggest game changer for me. After that, MiniDSP allowed me to add my 2nd, 3rd, and 4th sub, and using that with REW ensured I was getting the flattest frequency response. Extracting the last bit of performance was then being able to add my own house curve, and input BEQ. You'll get every last bit of potential from your investment. And I know it's a big investment!

Most home theater guys are chasing SPL and grunt, and there’s no better option than JTR for that (PSA wins the silver in that category). Others who have dual systems (music and movies) want the best sound quality and easy integration with their mains. For a music only system, REL is hard to beat (though they won’t go as loud or as low as many others). but Rythmik is right there in the sound quality category (Arendal is also a good option). For those who want BOTH slam and sound quality, the big Rythmiks offer both, and compared to many other manufacturers, the price is reasonable. For me, they hit the sweet spot, offering slam, SPL, refinement, easy integration and great sound quality.

[@benjaminvankuren7645]

Just wanted to point out that the Limiter switch is for attenuation overly high peak voltages. The Rumble filter is the one you were describing that has a steep roll off at the chosen frequency.

[@Mudcat3434]

Yep and the LIMITER should ALWAYS be on. Never in the off position.

[@PolkFan]

Man thanks for the explanation of the PEQ. The way you explained it made things as clear as day. I've since made some config changes and have my subs sounding better than ever. Enjoy that beautiful setup my man.

[@blueflame0003]

Its nice to see you grow....i hope people take your advice...i have been telling people for the last year seal sub is the way to go...i have dual 18inch subs just like that 1920 watts 4300 peak. Elected to go ipal woofers instead of high excursions ones....they go down to 7hz,but i tune mine to 10hz....PSA S3612....still afraid of them but the pop at low frequency the minute i hook them up to my denon x8500h...this is why im getting the avm90 to see if they still pop.i use pioneer sc55 the first time i bought them they work fine but have volume gain max....with denon its half that....anyway glad you are moving up very well..those subs are perfect for you...great video chow

[@Kpaceguy]

Thank you I appreciate the kind words!

I think a video showing the difference in how it measures in the room depending on position would be interesting. I know my subs have a lot of variance depending on where I have them positioned.

[@deankim6687]

Your the second of the two reviewers of this sub that mentioned how it’s much better than the 16 Ultras.

[@darrennielsen3758]

Couple things I’d be interested in why you chose Rythmik as a company? Their customer service isn’t nearly as easy to get a hold of as SVS or Arendal. What other subs were you considering at this price point? Why not SVS SB 16 or Arendal 1723 Subwoofer 2V? Or spend a little more and get the JTR Captivator RS1 or Funk Audio 18.0E?

[@chrisrichardson958]

I just wanted something different. I really like the servo technology rythmik customer service is excellent. I would have liked to get the jtr but the build time was long and it was more than I wanted to spend same with funk audio I know those are end game subwoofers but for me I did not need a wood grain enclosure it’s cool but not worth the price funk charges. As for Svs the sb16s are good I have heard them but the rythmiks go deeper and have better tuning options. Arendal was a consideration definitely but I just keep coming back to rythmik. For me personally They are perfect. I’ve talked to Brian directly and he is amazing super knowledgeable person and he really stands behind what he sells. What subwoofers are you thinking of going with ?

[@codyparnell]

to me it depends in what you are looking for from a sub

[@Sloimer]

SVS subs aren’t very musical. As I understand, if you want the best subs for music you get Rythmik, and if you want maximum bone crunching output for Home Theater, get JTR. I have two JTR RS2’s - more output then I’ll ever need. Considering selling one and buying two F18’s, then sticking the other RS2 in a nearby closet and rolling it out to supercharge bass when I’m feeling silly.

[@Tacet137]

None of those are servo, SVS has horrible group delay, Rythmik has the best group delay of any sub on the market (only perlisten is equal)

[@superdan43]

100% agree with every word you said.. My Rhymik F-18 Subwoofer produces the most smoothest cleanest deepest bass I've ever heard in my room.. keep the updates coming.. great job as usual.. 🙏🏾🙏🏾🙏🏾

Very nice review of a great Subwoofer! I just wanted to add that Salk Sound also uses the Rhythmic drivers and amps in their Subwoofers. I recently purchased two of Salk Sounds version of the G-25 and they were able to match the mahogany veneer and gloss finish of my Main speakers perfectly. They sound sublime. Thanks for taking the time to do such a wonderful review.

The driver is a special version of their 15" model 1520 which is only available on two of their top of the line subs.

[@chrisrichardson958]

I just received my two f18s ! They are amazing I’m wondering those bottom settings what did you set your at ?

[@MeTuLHeD]

When you're ready to upgrade, just buy a second G25HP. By the way, the tightness you're experiencing is a combination of several factors...the sealed enclosure, the dual opposed drivers and the servo control. All work together to make that sub tight without sacrificing power and impact.

[@Kpaceguy]

I want a 2nd one but it's A LOT lol one day

[@roccobruno8027]

Given it's an analogue amp it would be great if you can dive into all the settings when you can. I'm also curious how having two of the Dual 12" G22 would sound, but for some reason they don't come in a white gloss finish.

[@pierrecastanets1974]

That's a big sub. I considered rythmik a few times but the "back order" status on the page always scared me off. Availability is an under-rated "ility".

[@failingup4907]

Kpaceguy, great review. These are $2999 now and you can't get it in white or gloss black. I have an old Power sound audio XS30 dual opposed 15's like this one. Of course there is no servo. I might sell the xs30 and get 2 E18's. If I just added the G25HP to the sub I have now, I'm not sure if it would be a good match or not.

[@Kpaceguy]

@@failingup4907 you can only get it in the ash color?

[@deankim6687]

I think I’m going to go dual E15HP2 SEs, which is basically equivalent to a G25HP, per Enrico at rythmik. I’m 90% music, I don’t listen to music that loud, and I don’t have the space for G25s. I won’t get the benefit of canceled vibration in the box with dual opposing woofers, but I get better smoothing through placement of two subs. It is cheaper to get a G25 than dual E15s though, even with the multi sub discount, which isn’t much at rythmik to be honest. I have to go duals, and getting dual G25s isn’t cheap.

[@Novilicious]

Consider the e22 or g22 from Rythmic. I think you may like that more than e15 se. I’m debating the same but think I will get the REL 812 subs. Also, I only believe in stereo pairs

I'd absolutely watch a video with you going into all about the subwoofer. Topics for a future video could also include results of different positioning Such as the drivers pointing to the sides of the room or pointing front to back.
