Those LFE freaks, do check out Wanted. Some pretty good LFE in that one.

There is a dolby encoded test disc that reproduces the frequencies that u need to test to see if there is a problem with ur sub. Its at the AVS forum and is a free download. I will see if I can find the link, else I will pm u and we can see how I can pass u the disc.

Do let us know ur impressions as u listen more. Was this this when compared to the pb13 for movies or music?

Same price in Penang as well. 14k+ but did know know that was for the cherry finish.

Wow...cool. After u spend time listening do let us know.

There has not been a FR chart in some time, thought I would spice it up.

Close mic'ed response of my Rythmik Audio F15 PEQ2 DI, using 14Hz and High Damping setting. This is in DI LFE mode (with extension to 200Hz). In this mode all crossovers are bypassed. This is not a max SPL chart.



Behaves as spec'ed with -3dB at about 14Hz.

The next chart is at listening position with PEQ and no Audyssey. Some boost below 14Hz. The dip at 90Hz is not really worrying as the other sub evens it up. When I have the time, I will rechart with Audyssey and the dual sub readings.


Good sealed sub response. The decay times are not shown but since my room is not treated so it is about 500ms.

This is without Audyssey, the results are flat enuf for music and with the single band PEQ the listening position together with the fronts are pretty good. Its a good sealed sub. For those who are into movies, I would suggest ported subs as it has the big sound feel for movies. Rythmik just released some ported subs and submitted them for the audioholics sub shootout, so lets see how they stand.

Of course, we all know how the famed SVS subs are for big sound moments. I wonder how HSUs new ported 15in sounds like.

ronaldjoe,
This is close mic'ed response. The 2nd chart was at listening position. My room is 17 x 15 but opens up on the right to a 30 x 12 ft.

Not necessarily. Some people have heaed my setup. As music is my primary goal, I don't need loads of bass still I get enuf kick for movies. Of course, multiple good subs would be better.

Audioholics recently reviewed the SVS PB12-Plus and as expected its one powerful sub, loud and very good overall perfomance. I wonder how the others will fare.

On another note,I believe there will be an announcement soon about a dealer/rep/distributor for Rythmik subs for the Malaysia/Singapore/Thailand region in the coming weeks. I own a F15 PEQ2 DI and have heard SVS subs quite a bit. They are different and excel in different areas. It gives Malaysians a choice, plus I have been told that the 1st few batches will be very competitive in price...

I am adding a sub, either the F15 or the FV15HP.

I will open an owners' thread once I can confirmation or the green light. Will also see if I can get Brian or a Rhytmik rep to participate in the thread....

I bought my F15 used and upgraded to PEQ2-DI.

I believe the 1st shipment will be F15 and FV15HP. I don't think its worth to bring in the F12 as the price difference is minimal. Lets wait for the price confirmation but I believe the price would be competitive.

azbro,

I'm not htkaki butif the floorstander is capable till 50Hz, then cut it off at 70Hz. (20Hz above the rating). Still set it small.

My speakers are rated at 37Hz. If u look at the anechoic chamber FR u will notice that it is flat till about 60Hz then it starts to roll off. The roll off continues till about 37Hz where it is -3dB. As you can see, it starts to roll off at about 20Hz from its rating. For music, it will do fine playing full range as most instruments (even bass guitars) don't go much below 30Hz and normally not at high SPLs anyway (unless bass heavy tracks).

Also most front speakers are ported and tuned at higher frequencies. What I find now is that a proper sealed sub can supplement a good floorstander for music as well. It just gives u the extra depth... (the warmth that people talk about)

For movies, the fronts and the centre do a lot of work. So to take the load off, setting to small and redirecting bass to a capable sub will allow more definations for the fronts.

There is almost always more bass on a floorstander than a book shelf. (Note : almost always, depends on the design)

For music, moving from bookshelves to floorstanders were a revelation for me at least.

Syrius.

I run the my 2 unidentical subs using AS-EQ1 and allow AS-EQ1 (in ur case the 4311) to equalize the 2 subs and it works just fine. The sub eq will find the -3dB frequency of the sub and redirect bass accordingly as far as I was told, I might be wrong.

As I indicated earlier, there now is an official overseas distributor for South East Asia.

Sound Fusion Sdn Bhd.
Rythmik Audio SEA Distributor

junwei who is a forumer here is working on bringing in a small 1st batch.

I will start an owners thread soon.

I hope this will spur more interested people to hear how the F15 and the F15VHP perform. I believe these are the 1st 2 models to be brought in.

Yeah....Even after the intro, he is trying his best to keep prices very competitive compared to if the person were to buy it direct from the States.

The Rythmik F15 (PEQ2) has a LFE mode that extends the -3dB to 200Hz. So no issue. I believe the SVS shd be no issue as well.

logit,

since u r writing some pretty intense words like Xmax and all, what is the lowest frequency the album is recorded in? What is the spl? If u do not know this then how will u know anything is ever enuf?

These subs are usually used in clubs or open areas....so the hump in the mid bass region will more or less drown out a lot of other things as well. I believe it will come close to advertised easily interms of max spl. The only issue is the distortion numbers.

If u guys are really looking for mid bass modules why not HSU MBMs?

weim,

It really depends on the sub, the placement on whether its 1/6 or 1/8. Some subs have high gain set in the amp that cranks it up very fast.

If possible, I would advise to get a SPL meter and double check the levels after Audyssey.
