I haven't opened a Rythmik sub, but I've taken out drivers from other subs and speakers.

It's easy to do, but one thing to watch out for is that both the driver and the amp are surprisingly heavy, and they tend to jump out if the sub is standing up.

Unscrew one when it is facing up, so it won't roll out. Then, either lift it out, or very slowly and carefully roll the sub over to roll it out with a hand firmly holding it.

Don't touch the inside of the amp, because there may be lethal voltages, even though it's not plugged in.

It's easier than it sounds.

I have a sub in the front left corner of my room, and one in the rear right corner. They are crossed at 80 Hz. I would bet a paycheck that if I brought you into the room blindfolded, put you in the middle and played music, you could not place the subs.

^^^ I could. You have one in the front left corner and one in the right rear corner, right?

Locating the sub playing is not the issue, when I had the sub behind me I couldn't locate it either. But there was something wrong with the overall sound, and I could not figure out for at least 5 months... until I tried the middle placement at a whim.

Your setup needs to be really high end to reach this issue though. I never had this problem until I started to seriously upgrade the components behind the LS50. (Or you could say that I never had the ability to reproduce stereo imaging until recently.)

If you sat in my room you would think the my single sub was on the left side right beside you but it's is really located in the front inside the speakers on the right side. Phase problems.

Ya man its very low mileage. I've had it for about 1.5 yrs and hasn't been used since December of 13.

Its only hit the limiter 2 times because I made it during the server room scene in pulse.

I'm really easy on all my equitment. The fvs have still never hit the limiter as far as I know. I like to have enough output with my subs that I don't have to strain them to get desierable output. Same goes with all my audio gear. I like having plenty of head room I guess.

I am not a big believer in the "expensive means better" theory. The stereo imaging from my inexpensive setup is so convincing at times that I have to get up and ensure the center speaker is not playing. I just think that the point of diminishing returns can be reached very very quickly when it comes to home audio. At some point, I think people are just paying for an expensive name plate, and not necessarily better sound or quality.

Aren't you're also the one who thinks you can buy a sub like you can bolognie at the local deli?

Not sure, as I don't understand your analogy, sorry. But I can clarify my subwoofer purchasing belief: Buy two subs that meet your needs if budget allows from one of the ID companies such as Rythmik, SVS, PSA, or HSU. If you cannot afford to buy the sub(s) that meets your needs, buy the best one(s) you can afford.

P.S. If I were in the market to buy bologna, the local deli sounds like a great place to get it.

I think the point about "diminishing returns" is valid. That last 10% of performance can cost big. There's also a "herd mentality" in audio. A couple of glowing reviews and a speaker or component is suddenly the bomb. What constitutes good sound is very subjective and personal: we need to rely on our own ears to make that decision, regardless of how well received something is or how much it costs.

The LS50 is a great nearfield monitor. I'm suggesting to the guys I know with home studios that they get a pair for monitoring their recording and mixing. They're good enough for that---in fact, they are far better than what a lot of big Pro studios have (Yamaha NS10, Auratone, Tannoy).

I am using the A370PEQ, I am wondering if there are issues with heat over the years with the plate amp in a sealed enclosure? Would it be better to house the amp in a different enclosure with opening for heat to escape or the external heat sinks is enough to protect the amp ? I have about 5 inches between the wall and the plate amp.

I do not understand the question. Are you placing the amplifier in a sealed enclosure, the sub inside a cabinet, or are you asking about the longevity of the amp in normal use? If the latter, assuming there is airflow around the amp, the heat sinks on the amp should be fine. Mine rarely get even warm to the touch.

The amp is in the subwoofers 4 cubic feet sealed enclosure. The sub is not inside a cabinet.

Just for clarity, when qguy said the "sub" is not inside a cabinet, he meant the plate amp. Guy, you must have built one of the DIY SoundGroup 4 cu.ft. flat packs. How did it turn out? I almost bought a pair myself, but decided to design my own and have the MDF cut at a wood shop locally. 4 cu.ft. also, but with much more bracing than the flat pack, and double-layer walls

Mine is not from DIY SoundGroup, I had my enclosure custom made. Front is 1.5 inch, the rest is 3/4 inch.

To all my fellow Canadians who purchased one of Rythmik subs, preferably the FV15HP, what was your shipping method?
I'm seeking to purchase two early 2015 and those shipping prices seem pretty outrageous.

I'm thinking to probably do a kinek point to save on the brokerage and shipping. So just let me know what you guys did regarding shipping method.


Thank you,

Thank you,
I bought with prepaid taxes brokerage and worked out great, nothing due when it gets dropped off. Love this sub. For the E15HP I believed it was about $1600CDN all in taxes shipping duties, I thought it was pretty good price, still cheaper than buying the SB13Ultra from SVS in Canada.

Prepaid taxes and brokerage is $1228.00 for both subs according to their website. I'm not going to pay 50 percent of my order in shipping costs, that doesn't make sense to me.

Still at $2000 each shipped and taxes in is still a solid value, but if you can save by doing the brokerage yourself wicked. I know there is someone from Edmonton on here who did his own brokerage when he got his Salk speakers imported, DSL222 is his username you can send him a message.

There won't be an issue. The plate amp's heat sink is on the outside, so most heat is disspated out. There might be some minor heat built up inside, such as the transformer, but the enclosure is large enough to handle it. Maybe the speaker coil will produce more heat when driven hard. As a matter of fact, my DIY F15 sealed box has been running for 4-5years on a fairly regular basis, never missed a beat.

Locating the amp outside will be a hassle especially for the Rythmik, because there are 4 wires between the speaker and the amp (for the servo feedback). And I don't know whether extra wire length will cause further trouble.
