Professional Monitors

I'm toying with the idea of using pro active monitors for a 7.1 HT. Have been surfing and in addition to the Solo6, the JBL LSR4326P has piqued my interest. Take a look at their site: http://www.jblpro.com/products/recording&broadcast/LSR4300/index.html

If you click through to the "spec sheet" for the lsr4326 you'll see that they provide alot more detail and measurements than does Focal. Among the comments on the site, "The exact geometry of the waveguide,
the interaction of the woofer and tweeter,
and the network are designed to provide an accurate
listening window of ± 30 degree horizontal,
± 15 degree vertical", and one of the lines on the FR graph is of the average across the listening window.

The reviews seem good. But there is less commentary on the LSR on gearslutz.com, and no direct A/B comparisons that I've seen.

I am months away from trying to audition anything (the room isn't even designed, much less built). I'll be interested to hear what you and others here have to say after hearing the Solo6 and the LSR. I understand that some pro dealers allow returns of equipment after a home trial. (For instance, mercenary.com for Focal pro.)

Gb ksu,go to gearslutz.com and search for Solo6 or Twin6.The site is a forum for many recording and mastering studio engeneers.Many positive impressions on these monitors.Im trying to build 2ch. system around my Arcam C-30 preamp,which has balanced outputs.I have checked Event monitors ASP8 which are more of a midfield monitors, but the Solo6 have picked my interest.Good luck.

Bob,

I suspect the dip occurs at resonance of box and driver system (see the impedance curve). The port looks like it is tuned around 40 HZ (low impedance point) to get better bass extension - this will introduce phase delays around that frequency and affect the transient response.

You are right that a small speaker and a separate sub tends to get better results (like the NHT XD). There are also some monitors that are small without reflex ports that will sound more accurate in the bass and lower mid (but at a risk of sounding a bit bass shy). Alternatively a bigger box speaker is the way to go.

However, I felt that the JM Lab Chorus 706 distortion extended too far up into the lower mid range for comfort (but you can't be too picky with a $450 price tag which makes it a real bargain).

I just suggested to investigate the Solo6 based on its superficial similarity to the Chorus 706. The "pro" monikor and active design suggests it should be better...

Shadorne,
You make a point about distortion. I have not seen any graphs concerning their distortion, so I can't say one way or the other. I would think that given the intended use of the product that distortion would be low over their capable range. Doesn't make sense to me that a monitor designed to aide in professional music recording that had high distortion would be accepted. Especially in a range an instrument would play. I could see it if it was below 50 or even 40 Hz because there are not a whole lot of instruments that play that low.

Again these are all assumptions on my part, so please don't feel that I'm trying to discredit your post. I have contacted a gentleman that works with the company that handles the North American distribution for Focal. I will try to see if he could possibly give some insight to this question. I will let you know if I get some answers.

Gb_ksu,

They do look like a bargain. However, this reflex port design in a very small box speaker (6.5" woofer) will be unlikely to give you accurate bass. (i.e. you can't have your cake and eat it....great value will come at a little compromise)

I haven't seen measurements of the Solo6, however the bass design appears reminiscent of the Chorus 706, except Solo6 is an active design.

If I was buying the Chorus 706 then I would be concerned about the THD+N from 50 to 250 Hz from this small woofer and reflex design. (in percentage terms the THD+N distortion is around 20% in the bass up into the lower mid range)

The Solo6 may be a different animal (much better perhaps?), however, as they say, if it looks to good to be true...

I'd definitely investigate these first.

Have you experimented with a seating distance further away from the monitors? I am assuming that 8 feet gives you optimal performance? Bum deal about them going out of business. I never had the opportunity to experience of their models, which is a shame since they seem to have a great reputation.

The Solo's do look like a great deal. I just wonder if it is too good to be true. I'm curious about how they would perform off axis. I just bought a home last fall and have 3 seats in the room right now. The width won't allow more so I will probably tier a couple more behind what I have. I know that Focal recommends that the tweeter be at ear level. From the experience I have had with the Electra BE line, this is an issue. I will always be in the "sweet spot" so it's really not a huge concern for me, but I just don't want it to be horrible for those off axis.

I sent an email to a Focal Professional rep. to see if there is anywhere remotely near me that I could possibly go have a listen. I'm keeping my fingers crossed.

They are ported. It is a rectangular port below the mid/bass driver.

Seems like they would have some advantages with the tweeter and bass adjustments as far as flexibility within the room and personal preference. They suggest 1-3 meters from the listening position. I wonder if there is an optimal distance within that range?
