"Musical" subwoofers? Advice please on comparing JL subs


I'm ready to be taught and I'm ready to be schooled. I've never owned a subwoofer and I'm not so hot with the physics of acoustics. I've had my eye on two 10" JL Audio subwoofers, the e110 ($1600) and the f110v2 ($3500). I hope this is a simple question: will the f110v2 be more "musical" than the e110?

Perhaps unnecessary details: I'm leaning into small bookshelf speakers, mini monitors with limited bass, for near-field listening in a small room. I don't want to rock the casbah and rattle the windows; I want to enhance the frequency range from roughly 28hZ to perhaps 90 or 100hZ: the lower notes of the piano, cello, bassoon, double bass, etc. I think I'm asking: will one of those subwoofers produce a more "musical" timbre in that range? Is spending the extra $2000 worth it in terms of acoustic warmth and pleasure? More generally, are some subs more musical than others? Or is that range just too low for the human ear to discern critically? 

I know there are a lot of variables and perhaps my question can't be answered in isolation. If it helps, let's put to the side topics such as room treatments, DSP and DARO, debates about multiple subs, debates about using subwoofers at all, and the difficulties of integration. Let's assume a fast main speaker with limited bass. I'm not going to put a 12" sub in the room. While I'm not going to put four subs in the small room, I would strongly consider putting in two, and it would of course be much more economical to put in two e110s. This, though, would only lead to the same question now doubled: would two f110v2 subs sound more musical than two e110s? Also, I'm sure there are other fine subs out there but I'm not looking for recommendations; if it helps to extrapolate, consider the REL S/510 and T/5i. 

I realize that I may be wildly off with all this, and I know that the best way to find out is to try them out. I'm not at that point yet. I'm simply curious about the "musicality" of different subwoofers.

It's hard for me to exaggerate how much all this helps me and how much I appreciate it. In this case I don't feel discouraged by the differing opinions, as I know there are many paths to a good result and each post is thoughtful and informed. For example, I know that Eric is correct: a CR1 + F110 would cost close to $7,000 new, and if I were "very experienced" or had calibration tools, I could achieve similar results for much less money. (I'm not and I don't, but I also don't have the big bucks to throw around.) 

Let me say that I appreciate the recommendations about different subwoofer brands. I've heard great things about REL, Rhythmik, Hsu, and others. And @bailyhill, I have huge respect for Vandersteen and John Rutan. I seriously thought about the Treos before making the decision to try near-field. 

@mijostyn, that's an excellent description of the process. I've read many explanations of sub placement with the Fathoms but yours was particularly helpful. Placing the subwoofer *before* the DARO sounds exactly right. I am worried about the phase alignment but your recommendations are very helpful. And YES about the crossover point for mini monitors.

@diamonddupree, hey now! I didn't mean to suggest that DARO doesn't interest me, just that I wanted to clear away as much as possible to get to my underlying question about "musicality" in subs-- and thus special thanks to you for taking that question on. What you write is exactly what I was curious about. I've just added "Wood" to my Qobuz list. Also, I'm not sure if your name is a reference to that band beyond description, but if so, right on, brother.

@audiotroy, I have to say that I find it off-putting when a dealer disparages a line he doesn't carry. I also think that, when you're presenting yourself as a professional selling specialized audio equipment, you might want to take the time to spell and punctuate. I genuinely mean that for your own good, as your words make an impression. 

Thanks again, everyone. I feel like I have a MUCH better sense of how to think about all this.


I forgot to add to my post, as some have recommended SVS is good, using an SB1000 myself for 2 channel and dual PB1000's for HT.
There’s no such thing as a "musical" or ("non-musical") sub. It either extends to a certain range at a certain decibel level within an acceptable range or it doesn’t. Don’t get caught up in the JL "musical" hype.

Some of the others are right about multiple subwoofers. You can read all about the reasons and placement in Harman’s white paper. To skip all the technical info just go to Conclusions to get optimum general placement for two or four subwoofers, although it’s also advantageous to understand why you place them at certain wave length distances, but the Conclusions will get you close. And although it doesn’t include all subwoofers, you can go to Data-Bass to get tested specifications on subwoofers.
Q: How many audiophiles does it take to screw in a lightbulb?
A: What kind of light fixture is it and how is it wired? Is the bulb dimmable? A watt is a watt but some watts are brighter than others. Before you change that lightbulb, have you considered room treatments? And so on...

I'm goofing around and I really do appreciate all the different opinions. (By the way, I have no idea if JL claims its subwoofers are musical; that was my word, not theirs.) 

So here's a question that should have an actual answer: at what hz point does the average human ear start to discern music, timbre, nuance? Is the lowest note on a piano, at roughly 28hz, just a low rumble of vibration, the same on a Steinway Grand as on a cheap cottage piano? And if that's the case, at what point on the keyboard can most people start to detect a note with resonance and beauty? By the way, I do understand and accept the physics behind multiple subs--no argument there at all.
