Hi Prakash Wadhani,
When the S1 Pro was released, I spent a great deal of time comparing the S1 Pro to the L1 Compact and preparing this article.
Bose S1 Pro Compared to Bose L1® Compact
In your link the specs are:
The S1 Pro: 62 Hz – 17 kHz +/- 3dB
The L1 Compact: 65 Hz – 14 kHz +/- 3dB
Does that mean the S1 Pro puts out a deeper bass than the L1 Compact ??
You probably can't hear the difference between 62 Hz and 65 Hz. It's different enough that if two notes at these frequencies were played at the same time, you might notice they are different - but not very different.
The L1 Compact power stand is larger than the S1 Pro and the L1 Compact has an 8-inch woofer compared to the 6-inch woofer in the S1 Pro. The L1 Compact sounds 'deeper' and it handles high-volume low-frequency sound better than the S1 Pro.
The S1 Pro: SPL is rated as 103 dB / 109 dB peak
The L1 Compact: SPL is rated as 106 dB / 112 dB peak
The L1 Compact being 3db louder ... does that translate to twice the volume in loudness iirc?
No, it takes about +10 dB SPL to sound twice as loud. Reference: Doubling Power vs Doubling Output
Approx how loud does the L1 compact sound compared to the S1 when both are driven to their max limits?
It depends on what you're playing through them. If the program material (sound source) has a lot of bass, you may find the sound quality degrades before you can get to the maximum level.
Question ... If there were 2 S1 Pros on either side of the stage facing the audience & one L1 Compact in the stage centre, again facing the audience, assuming they were connected to the same Mixer & getting fed identical inputs, could the L1 Compact sound as full, rich & loud as compared to the two S1 Pros if they were played interchangeably as an A/B comparison? i.e. Two S1 Pros v/s one L1 Compact ... (i hope i've been able to get myself across clearly).
It depends on what you're playing through them. If I have a mono source (mono backing tracks), if I have to take two S1 Pros with stands to get the job done, I'll take my L1 Compact instead. Unless I have to run on battery power.
Also ... Would the L1 Compact be able to put out more bass than the 2 S1 Pros (on stands) ... or would they sorta sound equal ??
It depends on what you're playing through them. For most applications, I find the L1 Compact provides more bass (not a whole lot more, but more)
I'm contemplating on an L1 Compact to add to my arsenal, hence the comparison (i already own an S1).
One last question: I believe the L1 Compact is a very dated model and is over-overdue for an upgrade ... should I wait for that or take the plunge?
We are always confronted with this question. If you need something now, get it now. If you don't need something now, then it's probably better to wait. There's no point having gear that you won't use.
I'm primarily looking for a miniscule setup ... that sounds terrific & sets up very easily + has a small footprint.
I already have over 20 15" cabs (jbl, rcf, ev, mackie, yamaha, etc.) but am looking at an audience of 50 to 60 (max 75 px) for DJ & Karaoke.
If you have an S1 Pro now and you're happy with the bass response, then adding another one will give you more flexibility.
Something small that i can port myself at my ripe old age of 58 without an additional overhead (someone to carry the gear for me).
So the question I'm arriving at probably is: two S1 Pros or one L1 Compact?
Sorry for the long-winded explanations ...
If one S1 Pro will get the job done - it's easy. Take the S1 Pro.
For DJ and Karaoke (running mono)
If one S1 Pro isn't enough, and I have to take two S1 Pros with speaker stands to get the job done, I'll take my L1 Compact instead. Unless I have to run on battery power.
The full carry weight of the L1 Compact is 30 pounds.
The full carry weight of two S1 Pros is 32 pounds plus the weight for two speaker stands.
When I tested two S1 Pros on speaker stands to one L1 Compact, I found the L1 Compact projected farther in every direction across its 180-degree horizontal dispersion than two S1 Pros. This means reaching a larger audience with a single L1 Compact than two S1 Pros and there's better support for low-frequency material.
However, if you want to run stereo, two S1 Pros do that well.
Does that help?
I hope others will join the conversation.
