Jbl Lsr6328p Active Monitors

[pi314]

I’m thinking of getting some JBL LSR6328P active speakers. From the same webpage, here is the spec sheet. The specs look amazing to me, in particular the great on and off axis frequency responses.

I’m a bit of a speaker novice (though I’ve been doing heaps of reading lately!). I was just wondering if people had any opinions of these speakers? I’m also open to other speaker suggestions, M&Ks, Genelecs, …??? Home theatre and music (2 channel as well as surround) are equally important to me.

The reason I got interested in the JBLs was after reading Sean Olive’s blog. (Sean Olive is Director of Acoustic Research for Harman International – I highly recommend anyone interested in sound reproduction to check out his blog.) In particular, the big brother of the 6328 is used in the new The Harman International Reference Listening Room(s).

Here is what he had to say about the LSR series of monitors (quote taken from here):

“The JBL LSR 6300 series are among the flattest professional monitors I've tested. Check out the published set of anechoic measurements of the 6325P and the 6328P below. Speakers don't get much flatter and smoother than that. Add a subwoofer or 3, and some room-speaker calibration and you're all set.

If recordings were made on speakers this good with proper room calibration we'd have fewer bad sounding recordings. If only the recording industry had standards - but that's a topic of it's own for another day.”

Anyway, I realise JBL is part of the Harmon group but after reading Sean Olive’s blog and being suitably impressed, I couldn’t help taking notice of the above comment and getting a bit excited

Please share your thoughts with me…

BTW, if you check out Sean’s blog and like what you find, you should also check out the writings of another sound reproduction guru, Floyd Toole (a good place to start are the articles in this thread Toole articles).

I'm still interested in comments if anyone has any....

Unfortunately, I don't have any experience with active loudspeakers, and I have not had experience with JBL loudspeakers.

The loudspeakers based on the pictures, and the specifications, make these appear very good, indeed.

I would certainly recommend to have a listen for yourself. If they sound great to you, grab them!

I've heard nothing but positive things about the JBL LSR series. The 43 series also looks good. It is a bit more recent and may give similar performance at lower cost.

Another good thing about the JBs is that they are universal voltage so you can buy cheaper from the States.

I would get them just to tell people that they have:

"Titanium composite high frequency transducer with Elliptical Oblate Spheroidal waveguide for precise pattern control"

They certainly look like they could be an excellent speaker

[cwt]

Being professional monitors pi314 they are designed for use as recording studio monitors [and anechoically treated rooms] but no reason they wouldnt be exceptional home speakers . The +/- 1.5db frequency response is flatter than the traditional +/- 3db rating given to regular speakers so all the flatter freq response

You didnt mention your system . Do you have a pre pro or avr with preouts ? one or the other is required and the speakers [like a lot of actives] are very easy to drive with high spl's due to the synergy of the power amps and drivers I would also consider the catalyst sparks ; dont know how much the jbl's are but Blades catalysts are good value for money.

[BladeRnR]

The JBL's look impressive but have you considered Seaton Sound Catalysts?

Seaton Sound Catalysts

A quote from Mark Seaton:

In my mind, the fact that the speakers can reproduce ~125dB @ 1m at any frequency above 80Hz within linear operating limits is not the most impressive quality.

Despite what Mark says above I was so impressed I've bought 3 of them for the front stage. 2000watts each.

I'd certainly like to see how they'd stack up against the JBL's or other professional monitors.

Thanks Dan - hopefully I'll get to hear them before deciding if I want to purchase them.

Hi Blackwash,

I haven't done as much research on the 43 series but apparently they are quite good though I believe not quite as good as the 6328's.

Yes the universal voltage thing is great. Now if we could just get companies to price universally

Hi cwt,

Thanks for the comments.

No - I don't have a avr or pre/pro as yet. The JBLs only have XLR connections and hence I was thinking I might get the new Integra 80.1 pre/pro though I haven't really thought much about the pre-pro/avr thing as yet.

Thanks for mentioning the catalyst sparks - I'll have to look into them.

Hi Blade,

Thanks for the link - that SPL and power are huge!

My room is only very small (3.3m x 3.7m) and hence these would probably be too much. In any case, I certainly will check them out with interest. BTW, the max SPL @ 1m of the 6328's is more in the range of 111 dB but thats probably with some distortion. Power is also much less.

Yeah crazy SPL but in a very large HT room or auditorium it's probably appropriate (And useable).

My full review will follow when I get hem early next year.

Understood pi314 ; xlr conections makes it easier to choose [and knocks out a few like the new nad m15hd ]. Very thin on the ground at a reasonable price; apart from the 80.1 ; the cary 11a and maybe the denon avp-c1x if they ever release it

Thanks for pointing out the Denon AVP-CIX. I had no idea of its existence. Looks like the earliest it will be out is about mid-2010. I take it they haven't released official specs, as yet? The best information I've found so far is the following:

http://www.avforums.com/forums/denon-owner...avr-4310-a.html

I wonder how it will compare to the Integra DHC 80.1?

Edit: Apparently non-North American Denon's don't support Audyssey Pro I can't believe this...

Thats all I found too pi314 .It'l be interesting how they spec the c1 ; the avp-a1 is fully balanced input to output ;maybe the c1 will be unbalanced like most ? Apart from the sound quality ? the integra has 1 extra hdmi ; isf calibration capability and reon instead of abt video processing for the denon . Or get 2 seperate boxes one audio one video to eliminate cross emi/rf completely [ime a cary 11a owner if you cant tell ]
