The Quad ESL 63 are classic loudspeakers that have been around for decades. Even now, there are HiFi enthusiasts who are still using them to listen to their favorite music. One of the main reasons is that it is really enjoyable how the Quad ESL 63 speakers sing. When it comes to accuracy though, the ESL 63 does have its flaws.
This is mainly due to the fact that Quad ESL 63 is lacking in the deep bass department. If you listen to a lot of bass-heavy soundtracks, you are probably missing out on the low-end frequencies. Even for classical music, there are a few instruments capable of reaching deep into the bass extension. For instance, the church organ can actually go below 20Hz and there’s no way the Quad ESL 63 loudspeakers can deliver such subterranean bass.
To resolve this issue, you can think of adding an active subwoofer to help supplement the bass performance. Depending on how good the subwoofer is, it can help deliver bass frequencies of down to 20Hz and below. If you are worried that the subwoofer might produce overly pronounced sub-bass which will overwhelm your Quad ESL 63 loudspeakers. You can choose to get a sealed subwoofer. The sealed subwoofer has a tighter bass performance and typically is agile enough to keep up with the music.
If is purely on bass output, then you should go for a ported subwoofer instead. This type of subwoofer is more efficient when it comes to reproducing low frequencies but the bass delivery is not as tight as a sealed sub of the same caliber. So, you need to weigh the pros and cons or set some requirements before choosing which type of subwoofer to go for. Usually for music listeners, you might want to just stick with a sealed subwoofer.
Having a subwoofer can also help you with your Quad ESL 63 speaker positioning. To get the best bass performance out of the Quad ESL 63, you will need a specific speaker angling and position but with a subwoofer, you can kind of focus on the higher registers. We have listed some of the best subwoofers below that you can consider getting, please take a look.
