Rythmik F8

By Jim Wilson (theJman)




The Rythmik F8 fills a niche that seems to be almost universally neglected by virtually every other subwoofer manufacturer, a market segment that really doesn't get much love. Not everyone is a "basshead", the type of person who enjoys being pummeled by low frequencies from everything they listen to. There are those who want detail and refinement first and foremost, people who don't necessarily need to have the fillings dislodged from their teeth on a regular basis. The Rythmik F8 subwoofer is for anyone who savors composure and finesse, the discerning audiophile that also enjoys a good blu-ray movie on occasion. Compact in size yet big in every other way, the Rythmik F8 is the go-to choice for the discriminating individual who relishes subtlety. Pretentious and grandiloquent it's not, but eminently satisfying it certainly is.

Re: Rythmik F8 Discussion Thread

Good review. I am a professional recording studio and theater designer, and have been recommending and installing Rythmik subs for several years. The price/ performance of the Rythmik line is unsurpassed, and my clients who now use these subs (in professional settings as well as HT) have all been blown away, especially in comparison to other manufacturer's subwoofer products. Brian Ding is a dream to work with, and the technology in the subs enables optimization in any critical listening environment.

Excellent review! I recently bought a pair of FMB 8's to provide some mid bass kick to my Sierra 2's. I think good mid bass response is a very underestimated element of good sound.

My guess is you're going to have quite a smile on your face with that setup. Be sure to leave your impressions when the opportunity presents itself.

You are correct sir! The bass is uncompromising, clear, nuanced and powerful! Brian Ding, the owner of Rythmik (and a phD in electrical engineering) made the point that the most impactful bass is not in the lowest registers, but in the 60-70 HZ range. He offers the FMB 8 to captures these, and man do they deliver! Besides the great bass, all of the low notes appear that they are coming from the front, even though I have 4 subwoofers (2FMB &'s and 2 sealed Rythmik 15's), a characteristic I attribute to the efforts I made to phase align them. This should be standard operating procedure for anyone who likes to hear all the bass powerfully. No matter the size of your fronts, they aren't going to perform like these babies, particularly when most fronts (including mine) are not in the optimal position for bass reproduction. Highly recommended!!!

Re: Rythmik F8 Discussion Thread

Great review Jman. Sounds like these things live up to Rythmik's MO and reputation. Since you also have an E15HP, I am wondering if you could detect any evidence that the cliche "big woofers are 'slower' than smaller woofers" is true? I have not really bought into that myself, but I'm curious what you think.

There is some physics behind inertia and mass, so I'm not certain it can all be discounted. After all, no matter how large the engine and brakes are on a tractor trailer it will never accelerate and stop as fast as a Corvette will. That being said...

When properly designed and engineered a subwoofer with a larger driver can be made to respond in a manner quite similar to that of a unit with a smaller driver. You might be able to measure the difference between the two, but done properly it can be made virtually inaudible. Case in point, my next review will be on the JTR Captivator S1. Without giving too much away, the motor strength, wattage of the amp and alignment make for something that looks beastly yet sounds anything but. The FV15HP would be another case study; there's no way that thing should sound as good as it does, but somehow Rythmik pulls it off. To an extent you can have your cake and eat it too, but it takes a lot of time and effort for that to happen.

Looks like they could have fit a couple of 12"s in there ... Someone had to say it.
