Preliminary look at the Rythmik F15

Thanks to some test tones and a SPL meter borrowed from a forummer (you know who you are  notworthy.gif) I managed to chart the in-room freq response of the F15 vs the CHT-12Q.

user posted image

As you can see the F15 digs down to 10Hz in-room!! And it's fairly flat from 10-32Hz. By comparison the 12Q falls off rapidly below 32Hz and is basically inaudible from 25Hz and below.

So what does 10Hz sound like? Well I can't hear it. I can only start hearing some pulsations about 14Hz upwards (and this is probably due to the vibration of things in the room rather than the test signal itself). And at the test level of 80+ dB it's not powerful enough to really rattle the room. I've not tried pushing it higher yet.


*
according to either craigsub( i think it was him), even seating beside the sub, 15hz was wasnt heard or felt until.. errr.. 4got how many db but i am quite sure atleast 100db..

just curious how far was the mic away from the sub..

Heard that SVS will be coming out with 2 new sealed subs later this year. One 13", another 16"!

wonder if they will make a sealed cylinder in the future .... might look like a black 13 inch tire:) or a balck wedding cake

if no use also it makes your room look mysterious and magical. brows.gif

anyway, tried already with and without wall panels for main speakers. lucky, got some differences/improvements. haha  tongue.gif

note: i'd suggest making your bass trap thicker, maybe 8". check this out: DIY traps
*
main speakers got diff then bass region leh.. is it smoother compared to no bass trap.. just curious.. coz all the NRC published nvr show low frequencies.. not sure abt mysterious and magical but i am sure when my frens see it they will surely ask 'those hanging stuff are also speakers ah'?

i've done a simple test using REW to measure the effects on FR by removing just 1 front corner bass trap in my room.

With front corner bass trap, 80 Hz crossover:
[attachmentid=1151336]

After removing the front bass trap; note the circled areas.
[attachmentid=1151337]

so, definitely worthwhile to install bass traps and also looks like the more the merrier. biggrin.gif

i'll have to install more as well. brows.gif

anyone know how to read these waterfall charts:
with bass trap
[attachmentid=1151419]

overlay of the 2 charts
[attachmentid=1151421]

thank you so much boss!!!!

i certainly cant read those waterfall charts smile.gif smile.gif

I would pick the Submersive based on all the incredible reviews it has received. For sure it will be exclusive in Malaysia, you'll probably be the 1st to own one locally. Now, if only you can get Mark Seaton to service you since he's busy enough with US orders.

Another strong contender is the Hsu ULS-15 DualDrive, i.e. 2 units of the ULS-15. This has also got very good reviews and with 2 subs you can position them to even out the bass in your large room. Also quite exclusive locally.

this thread is really getting out of hand.. 6 months ago we barely see any other subs mentioned here except cht12 .. .. now submersive, ed, hsu ,axiom.. forgot we even have our friend with a rythmik sub rclxms.gif .. at least the chances of us tasting other brands of subwoofer increases.. hopefully the trend of having GTG will follow then we can try diff subs

Indeed, we seem to have progressed a lot in the last 6 months. Nowadays a lot of the non-mainstream brands get mentioned.

I suppose I could also suggest that xrossf1re get 3x Rythmik F15, which would easily fit his budget. But I'm also happy that he try others then we get more diversity and chance to listen to other subs biggrin.gif

Just saw this pro review of the Rythmik F12SE: http://www.enjoythemusic.com/magazine/equi...thmik_f12se.htm

there are many brands but i dont dare to try coz i am not familiar with their warranty .. i bought svs coz always hear ppl talking abt their excellent warranties even for overseas buyers... the rest of the brands i am not sure and too lazy to find out haha.. 3x F15 would be nice!!!

Well, in the forum...they said 2 Hsu VTF3 MK3 can match the performance of the Submersive (which have dual 15" woofer)....

Hsu does ship to M'sia tongue.gif

thought it is more likely 2 sealed hsu might have similar performance with submersive instead of vtf3 mk3

bro how big is your room .. u can also try http://www.edesignaudio.com/product_info.p...products_id=606 if u dont mind the looks.. this sub topped the ranking of the famous Craigsub list.. here http://www.tweakcityaudio.com/forum/showthread.php?t=11 .. .. total cost should be

usd2500
+ usd 800 (postage)
= usd3300+ tax around usd900 .. total around usd4200 x 3.55= rm14910

2x18 inch+1300 watt rms+390pound+TOP of craigsub ranking=EXCLUSIVE

ok Elemental Design has great support.. they have a online live chat line.. the sales rep told me A7-900 works in 240volt, and they r diff from other co if there is a defect in their product.. u DONT have to send back the faulty part.. after trouble shooting they will send u the replacement part:).. sounds good to me
