These are highly regarded entry-level studio monitors and have a price tag that will fit most listeners’ budgets without sacrificing accuracy. Whether you are just using the JBL LSR305 for casual music listening sessions or for audio mixing, you will probably notice the bass performance of the powered monitors is not deep enough. This is quite expected from an active studio monitor of this size and price.
If the music you are listening to or working on is not bass-heavy and doesn’t dig deep into the bass extension then probably this wouldn’t be an issue. But if you do require these subsonic bass reproductions, you can always add a powered subwoofer into the mix. It is wise to integrate an active subwoofer that will match well with the JBL LSR305 studio monitors and also fit your requirements. Once we have gone through this process, we will then share with you a list of the best matching subwoofers to go for.
Sonic Characteristics of the JBL LSR305 and Subwoofer Requirements
These JBL studio monitors are compact in size and this makes them ideal active speakers for small studios or desktop sound systems. You will need some distance away from the rear walls though since it has a rear-firing bass port. The JBL LSR305 is a 5″ studio monitor with a slightly above average bass output when compared with other more neutral-sounding monitors in the same price range. Placing them too near to the walls might make the bass output sound bloated and over-pronounced, causing an imbalance in the overall tonality and timbre. All in all, the bass reproduction of the LSR305 is still tight and flat.
When it comes to subsonic bass performance, this is where the JBL LSR305 starts falling behind as the subterranean low-ends are almost non-existent. If you are mixing bass-heavy soundtracks, this may affect your overall accuracy. The midbass reproduction is also lacking weight and you might even find it not impactful enough. As mentioned, this is nothing surprising for an active monitor with a 5″ (127mm) LF driver size. The JBL LSR305’s tweeter is 1″ (25mm) in size if you are wondering, and it is also driven by a Class D amplifier with 41 Watts of power (same as the LF driver).
The overall sound reproduction of the JBL LSR305 is accurate and has a nice level of clarity. It does lack some enthusiasm in its music presentation and may not be really ideal for casual music listeners. The amount of music details the JBL studio monitors could dig out is fantastic and would be great for professionals who require precision over musicality. It is also capable of projecting a wide soundstage which all listeners will appreciate, not to mention, it also has impressive stereo imaging. We are certainly getting a lot of sonic performance from an active speaker at this price point, and overall, the JBL LSR305 has exceeded our expectations.
These are neutral sounding powered studio monitors and their sonic prowess will be suitable for analytical audio enthusiasts who are looking for bang for one’s buck speakers. Since the JBL LSR305 are studio monitors and have such high neutrality, it will be wise to match them with a studio subwoofer. The size of the subwoofer’s bass driver will not need to be big though as a compact-sized active sub will be more ideal for nearfield listening. Smaller subwoofers tend to be more affordable and you might want to set a price range which you are comfortable in paying. Setting a price requirement will help to filter out active subs which are above your budget.
Listeners with limited space will require a subwoofer with a small footprint and if you still need it to be capable of producing subsonic bass frequencies of below 30Hz then it might cost a lot. If you have a limited budget, we will suggest taking some time to save up even more money instead of having to compromise. For users who are sharing the space with others, you may want to ask for their approval since the subwoofer will take up a permanent spot in the room and they may need it in the near future. Discussing with others to get more relevant subwoofer requirements will be a good idea and you should come out with some on your own too.
