Thanks for the additional info! The M2 will be quite a change I suspect from the 2384's I am using now.
On another forum, user notnyt measured a few JBL CD's on the 2384 and had this to say about...
Hi Rob,
Thanks for the info!
Kind regards,

Hi Rob, nice! Thanks for confirming.
I will be giving the them a try with the 2453h-SL drivers. I don't think I need an adaptor or spacer...?
Looks like they are going for $269 at:...
Hi Rob, Nice job! Love the large format driver on the M2. Makes me want to purchase a pair of those waveguides. I am not a user of this tool, but I understand one can import measurement data to...
Very cool! Looking forward to your data. Are all the waveguides constant directivity? Any thoughts on accounting for constant directivity eq or is it not applicable for your scenario?...
Thanks @wayner.
In addition to DallasJustice, jtwrace went with the Audiolense software DSP route and biamped his M2's and added 4 subs, with all drivers time aligned using linear phase digital...
If you are into computer based audio there are several state of the art DSP software packages that don't kill dynamics or microdetails. One can obtain the ideal minimum phase response at the...
Hi Rob, excellent! I totally agree, for the cost, they measure very well and certainly sound good to these ears. My measurements are similar.
Would be interested in your listening impressions once...
Beautiful!! Thanks for sharing!
Kind regards,

Hi Rob, user notnyt over at the AVSForum compared the 2430 with some large format JBL CD's on a 2384 waveguide, summarized:

I agree with AlanD about using a Harman target... While I have reviewed Dirac 2.0 in detail, I still think, for computer audio, Audiolense is way ahead of the pack when it comes to bass management...
Not the same JBL's but I run 4722 Cinema speakers using a digital active crossover. What are you using as a music source? Is there a computer involved? If so, you may be interested in going digital...
OK cool, thanks for that. Will it accommodate 1.5" exit drivers? Also, don't know if you have seen this on diyAudio?...
Re: A very experienced horn guru in Norway has recently made a superb new horn. It reminds me of the Klipsch K402, but significantly improved. It has near perfect dispersion from 500 to 20kHz. Just...
I can't imagine how good they sound and look in person! Top-shelf man. Congrats.

Measurements of a Crown XLS 1502 here: https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-crown-xls-1502-amp.6062/

I use a XLS 1502 on my JBL 4739 bins from 45 Hz to 630 Hz in a active triamped home environment. Don't think I have ever heard the fan turn on and by all accounts it is very quiet when on. Good clean...
Robert - very nice! Are you into computer audio? If so, then I would recommend Audiolense XO as a "digital" XO that would run in a software music players convolution engine like JRiver Media Center...

One of my favourite (and technically correct) explanations, with real world examples, in under 25 minutes.
@Ducatista47 - The Kii THREE's and Dutch and Dutch 8c's I measured and listened to, are a level up on any speaker technology with their cardioid designs. waveguided dome tweeters and sophisticated...
Awesome! Great voice she has!
Steve, maybe this tune?
