Hi toddalin,
thank you for the link.

Hi toddalin,
Would it be applicable even to the older model?
Also, as this is a JBL related forum, should we take it to P.M.?
Kindest regards,
Hi Ian,
Thank you for the explanation, specifically your reference to the "room boundaries effect" and the "passive radiator". Admittedly I heard only a few bass-reflex system since most of...
Hi Ian,
I do not know how to estimate it, as the apparent volume depends on the fill. Saying that, the raw volume is about 100 l. My best estimate of the driver volume is 6-8 l. Bracing perhaps...
Hi Ian,
thank you for your reply.
Ha, ha, small world, eh?
Hi Rob3606,
thank you for your reply.
As Ian noted above, the TAD 1601A that is currently mounted in the enclosure had been crossed-over at about 650 Hz in the TAD Exclusive series of speakers,...
Hi Ian,
I know. There is a gentleman marco_gea on the diyaudio forum, who is very knowledgeable about all the TAD Exclusive speakers and he posted about the cross-over. Saying that I wanted...
Hi Ian,
thank you for your reply.
I am currently using a TAD 1601A in the enclosure and if my calibration can be relied on the sensitivity is about 95 dB/W/M.
I do follow your explanation...
Hi Robh3606,
thank you for your reply.
Please note that I had moved any further discussion as per my post # 47.

Hi Ian,
in response to your reply in the thread https://www.audioheritage.org/vbulletin/showthread.php?43560-1-5-quot-wave-guide-shoot-out&p=445560#post445560, let me first reiterate, where I...
Hi Ian, all,
I do not believe that I had mentioned my project in my responses herein, that had been sort-of disclosed here:...
Hi Rob (sebackman),
thank you for your response and specifically for confirmation that the 5006815 is a 1,5" throat wave-guide. And no, I will not use 2451 or 2452 as I do have the 2450SL.
I...
Hi Rob (sebackman),
thank you for your response and the link to the measurement data.
I will certainly look at the data, the problem is, I am not sure that I can interpret them correctly. To...
Hi Robh3606,
thank you for your reply.
As I am not as knowledgeable as the forum members (hence my search for a wave-guide/driver combination that is documented), can you explain the "I was...
Hi dn92,
thank you for your reply.
I know about Athos Audio, I even corresponded with a gentleman who was contemplating ordering from them, but the quoted price was beyond my means.
Hi Ian,...
Greetings all,
it appears the the 4367 wave-guide is no longer available. Is thee any other one that would allow for a 600-700 Hz cross-over with 2450SL driver? I have the Aquaplassed diaphragm...
Hi sebackman,
thank you very much.
Kindest regards,

Hi sebeckman,
thank you for your generous offer.
The driver's core is 2450SL, and I have two diaphragm types - D16R2441 and another, a designation of which I do not know, it is Aquaplassed...
Hi sebackman,
thank you for posting the impedance, this further confirms Robh3606's post.
Would it be possible to post a the impedance curves in a format that I can further process, e.g.,...
Hi Rob,
Thank you for your reply.
I was wondering because I remember to have read that the standard requires that impedance does not drop below 80% (or was it 70%?), of declared nominal...
Hi grumpy,
you are correct, it is a plastic-like piece, partially covering the lead from the diaphragm's winding to the diaphragm"s terminal. Thank you very much for the clarification.
Hi ...
Hi Robh3606,
I am not sure, what you are asking; as written, I am trying to determine, how to connect the wires between the cover terminals and the diaphragm terminals. Thank you for the...
Greetings all,
I cannot spot a color on either terminal of the diaphragm, how do I determine a correct polarity?
Kindest regards,

Hi Ian,
thank you for the reply.
Not only I walked around the mountain, but I did practice some TIG welding for the calming effect due to the required concentration. ;)
I have re-read your...
