This review is a very long time coming. I’ve had these on the trunk burner for a year, unsure if indeed they were the best budget speaker ever, or simply a colossal failure in material design. The reality ended up somewhere in the centre.

These speakers are big… you can almost fit three of small JBL LSR305’s within the volume of among the 308’s. That is stupid massive for a desktop, specifically for my little office, which means this review is more centered on living room performance.

Some background information:
This is a little perspective as to the reasons this review is important. There can be an entire audiophile faction that believes in limited dispersion manipulated directivity speakers. The target because of this group is for speakers to have is bound interaction with the area. If you ask me this will provide you with more of a sense of being taken up to where the music was recorded rather than the recording occurring in your room. As a person who likes studio recordings because of their perfection, and hates most live recordings because of their flaws and background noise I don’t possess much interest in speakers made with this goal. My reference system includes a ridiculously wide dispersion.

The thing here which makes this relevant is that the JBL LSR308 in writing is damn near nearly as good at manipulated directivity as other things on the market. The best way to measure managed directivity has been polar measurements. That is basically a number of frequency response measurements, walking the measurement mic around the speaker to observe how much the quantity decreases as you set off axis. An excellent result will show a smooth uniform fall off as fast as possible. This is a polar response measurement of the JBL LSR308’s taken by Dr. Earl Geddes, a guy with some serious audio tracks chops, demonstrated in this program that he wrote for displaying these measurements.

To quote the nice doctor, “For $200 that’s an incredible speaker. There are of course better speakers, but at $200 I don’t believe ever I’ve seen an improved speaker.” To clarify, that $200 number may be the average price for each and every speaker, and pair can cost you double.

All of that if you ask me is icing on the cake. I found the speakers because I was hopeful that they might provide full range audio tracks for cheap. The JBL LSR305’s are the least expensive naturally good sounding speakers you can purchase. Those speakers are smaller, don’t play as loud, and because they’re smaller they don’t have the pattern control that’s possible with a more substantial speaker. In addition they don’t play as deep, or with as much authority as a more substantial speaker.

The LSR308 is speced to play flat right down to 37Hz. That’s plenty for some music, and unlike other manufacturers JBL Professional will not bullshit it’s specs. The LSR305 does 43Hz, which is quite deep for just a little speaker, but as I noted in my own review they stumble when asked to execute at volumes needed when partying in larger rooms.

So now which you have that little bit of background info, you can view there is a whole lot of hype and expect this speaker.

Components:
Waveguide Tweeter
The waveguide design is pulled from the flagship JBL M2 system, when using a tiny button magnet soft dome tweeter rather than a compression driver. The bigger the waveguide the more directivity control at lower frequencies. This waveguide is pretty big, and really should control horizontal directivity right down to about 2500Hz.

Woofer
Look at all those inches, 8 to be exact. The cone material is some form of polymer-coated aluminum or some such. I believe it is the same material that Infinity uses on it’s Primus type of speakers. The butyl rubber surround insures an extended life, and isn’t overly stiff.

Like all Harmon speakers I’ve reviewed this woofer includes a backing magnet. I did so figure out that is for a lot more than magnetic shielding, in addition, it escalates the BL of the driver. The bigger BL signifies that the driver includes a higher acceleration, getting where it requires to go fast with the excess little magnet.

Plate Amp
The plate amp take up the complete back of the speaker. It’s an enormous yet very thin little bit of sheet metal with a little amp screwed to the center of it. The Amp itself has plenty of watts. It’s a Class D amp that generates 56watts for the tweeter, and 56 watts for the woofer. I did so get somewhat of hiss only using unbalanced consumer grade sources and the gain turned completely up, nonetheless it wasn’t too bad with the speakers a few feet away.

Cabinet
The cabinet is a box with out a front or a back, it’s very good thickness MDF, but no bracing inside at all. Giving the medial side a knuckle wrap will leave you feeling hollow and unsatisfied. The 1/8 inch thick plastic front baffle and 1/16 inch thick unbraced metal back plate makes this the worst cabinet I’ve ever seen from a material selection stand point. The trunk panel flexes quite somewhat when inserting the energy plug or 1/4 inch jack. The wave guide reaches least an extremely stiff structure, but tapping on the waveguide you can feel having less material behind it.

I wish JBL could have talked to the Infinity Primus team about cabinet construction and gone for a bit more beef or bracing.

Port
It offers a port on the trunk of the speaker, which is comically mounted to the sheet metal back. The port itself isn’t too deep, and pretty wide. A lot more than any speaker I’ve tested up to now these speaker should be from back walls, if that can’t happen you then have to flip the -2dB activate the trunk of the speaker to drop the bass response since it can certainly smother the midrange.

Office Setup Listening Notes:
I had the 308’s in my own little 7 x 11 foot office primarily plus they just over powered the area with way too many bass, rather than enough placement options to get anything right. Here are a few of the notes I took from those sessions.

Break apart before they get loud. Scrambled like they are too large for the area, directivity can’t fix the stupidity of putting these speakers in this tiny room.

I keep checking the SPL meter and it’s really only reading out 85dB but it’s just packed with music, losing definition.

The exceptions will be the audiophile fare of music where its a couple of instruments playing. If the music isn’t busy they excel like nothing in this cost range should.

There seem to be to be issues with the very best octave sounding hot. Also, the speakers can appear to be they are yelling at the listener, which is something I find true with all horn/waveguide speakers.

Serious bass, but you’ll not be wondering where in fact the subwoofer is, the foundation of music is actually these massive boxes. These sound boomy too me, but most deep playing rear ported stuff does unless its 3 ft from any walls.

These need work, a sweep test shows the trunk amp panel using one speaker is rattling when 140-200hz is played. JBL said that they built these as cheap as possible, plus they weren’t lying. On the plus side you get the leading edge of tech for peanuts.

Male vocals are over emphasized an excessive amount of bass in to the 200-400hz range despite having the -2db switch flipped.

Does EDM like nobody’s business – Simian, Orbital, etc. These will surely be party speakers.
