Hey, happy birthday David, if today is still today (2 hours past Zulu time here, time flies quicker in here!).

Hey, happy birthday David, if today is still today (2 hours past Zulu time here, time flies quicker in here!).
I don't have first hand experience with the I-Tech amps, but I doubt connecting a D2430K directly will go smoothly.
There is a reason why JBL includes a passive network (-10dB pad and 1st order 1kHz...
I've never tried it as a sub myself.
There are probably cheaper options out there to use as subs, and arguably better for high SPL or to go very low (both of which are probably of no use for music...
Sure, I'm looking forward to that!
One obvious advantage is that it is new, so you don't have to worry about bad surrounds (ever again), wrongly installed kits, etc.
Compared to a 2235 it is objectively better on excursion (very...
These numbers alone don't mean much.
This driver is leaps and bounds ahead of vintage JBL woofers in every possible aspect.
Well, maybe it would not do as great a job as a door stopper compare to...
Indeed, on Erin's measurement you can see that the 305p has a limiter set somewhere between 96 and 102dB SPL at 1m, as the 102dB SPL curve is buried down low.
I bet the 308p can go a few dB higher....
Earl Geddes did bring a lot of interesting topics to the table for sure!
One I find very interesting is the instantaneous thermal compression that he classifies as a distortion, calling it "thermal...
I have been using an nc400 for the woofer and a THX789 for the compression driver.
This is by far the best amp combo I have ever used and the best sound I was able to get on the M2.
The THX789 has...
Hi Rob
Oh ok, I read Barry's comment wrong and thought he was talking about harmonic distortion. It appears it was just the HF itself.
Sorry for the confusion.
They look absolutely stunning, congrats!
Are you going to change your amplifiers?
Have you considered some of the new headphone amps for the compression drivers? 16 ohms is pretty easy to drive for...
Oh I see, interesting!
Is there any specific representation he is using for that?
Hi Rob
I wouldn't know! I have never seen those elusive HOMs myself.
The M2 waveguide is surely packed with those, so much so that they stop being a problem in the end :)
Funny to think that...
Hi Barry
What metric are you referring too? Is it related to his polar map tool?
IIRC I once read Earl Geddes state that he preferred to rely on magnitude/phase measurements rather than...
Aerospace Protectant 303 could also be an option as it is often used to clean and protect edrum rubber cymbals.
In Europe this product is difficult to find and we tend to use a product called...
Apparently you can get these Truextent/Meterion 4" Be diaphragms through Radian: https://www.usspeaker.com/radian%20index-1.htm
(search for "Radian 1245Be-16" in the page)
That said a 16 ohms Ti...
Thank you!! :D
I've now spend more than a third of my life on this forum (not literally, but you get what I mean hopefully :p)
Thank you so much Barry, I had stopped posting anything other than one-liners because of this formatting bug.
That should be a sticky, or maybe be made default and enforced in the database for all...
Synthesis SAM2LF/SAM2HF maybe?
I still read the site on a daily basis, but I don't have much to contribute unfortunately.
Oh I missed that! Thanks!!
There are several other proven options available if you are ok to separate the amps and processors: BSS BLU, openDRC, DCX2496, etc.
It depends on what you call expensive, but you can probably replicate the original filtering closely enough using hypex fusion amps.
If your target acoustical crossover is a 24dB/oct 300Hz LR filter you you will probably need a 24dB/oct low-pass filter on the woofer and a 12dB high-pass one on the midwoofer, filters Qs and...
Linkwitz-Riley is a great target for an acoustical filter, but unless your drivers have a flat response far behond the intended crossover frequency you will never get a Linkwitz-Riley acoustical...
