About 10 years ago I purchased a trio of AV oriented JBL speakers from a HiFi shop that was in the process closing down. I got what I thought was a good deal at the time (about USD100 in 2002). While the setup was a floor demonstration unit, it looked to be lightly used. At the time it was a major upgrade for me and I was very pleased to become a JBL owner.
The set was composed of a CENTER, a LEFT and a RIGHT. All passive. No Sub.
- The CENTER unit is a JBL 1810 CENTER
- The LEFT and RIGHT units are JBL 1810 SURROUND
As these were floor demo units, so I did not get a box, manuals, etc. So, that's pretty much all I know about these speakers. I cannot find any product literature on this set of speakers anywhere. Apparently, they did not have widespread distribution. In fact, the only place where I can find them is on 2nd hand auction sites in mainland China. Wierd. Maybe these are fake JBLs?
The only thing that I can find online that even comes close to what I have here is the ARC and FLIX series.
Here's the ARC CENTER info:JBL ARC CENTER Product Sheet
Here's the FLIX documentation:JBL FLIX Product Sheet
My conclusion? The JBL 1810 speakers were/are probably the lowest end JBL speakers on earth.
Hahahaha - well, that means it can only be UP from here! Hey, perhaps some even feel that these speakers are not worthy of the JBL name...but they have stayed in good shape over the years and I do not want to throw them out. What I want to do is fix the problems they have.The 1810 SURROUND
The 1810's SURROUND speakers actually sound pretty good for what they are, which is a single full range driver mounted in an unported, closed enclosure. Assuming they are basically the same as the drivers used in the ARC series, should have similar characteristics:
Please note that the above specifications is from the FLIX documentation. Seeing as these speakers have been used by JBL from the 1810 all the way to FLIX10 series, I doubt their characteristics have changed much.
My intention is to keep the 1810 SURROUND units exactly where JBL intended them to go - in service as surround speakers. In fact, I am seeking another set because my YAMAHA DSP-A3090 features a set of 7.1 speaker-oriented "expansion modes" which require a pair of "Front Effect" speakers:The 1810 CENTER
While the 1810 SURROUND units sound good (even great), the same cannot be said for the 1810 CENTER. Frankly, it sucks.
Sometimes it sounds OK. Not often. Most of the time, it sounds like someone is yelling through a sheet of glass, which is weird because the unit has all the right stuff inside. Two full range drivers, one tweeter. It even has a bass reflex ported enclosure to help boost the punch of the little 4.5 inch drivers. In my opinion, too much.

I am wondering if any of the JBL experts here can give me some pointers on how to improve the audio performance of the 1810 CENTER speaker? Here's the ideas I have so far:A - Blocking the Bass Reflex Port
I used a toilet paper core (stuffed, of course, with toilet paper) to block the bass reflex port. It had a (slight) effect on the sound but not really all that much.B - Stuffing with FillerC - Painting the cone with Puzzle Finish (or Similar)D - Adjustable CrossoverJBL 4206 MONITOR
I realize that none of the above 1810 units are "proper" main speakers. They are intended to augment an existing set of full range sound sources. So, seeing as I've decided to embark on this little High Fidelity journey, will be buying a set of JBL 4206 monitor speakers. Here they are - I intend to buy them tomorrow. They're in "as new" condition and will cost between USD100 and USD150 depending on how the haggling goes ED: They cost USD125
From what I have read about these speakers, they are good for a small footprint environment (my listening room / home theatre is tiny, only 9 feet by 8 feet. The listening area is only about 6 - 6.5 feet directly in front of the audio source and about 8 feet diagonally).
Apparently, the JBL 4206 MONITOR speakers have good range and will be a pleasure to listen to. I will be sure to let you know
Thanks very much
