Saw the thread just before it closed. Had never been there before so went there with no expectations. Agree on the animosity but makes more sense based on the forum culture you shared. Thanks. Feel no need to go there again!

Could be but seems rather shortsighted. His permission is more important than accurate representation of the speaker's performance? Does not play well legally and likely worse in the court of public opinion.:oops:

As was mentioned more than once, cannot rely on that graph I reposted from Stereophile. I later found this in another Tekton thread... https://www.audiosciencereview.com/forum/index.php?threads/tekton-style-like-tweeter-array-good-idea.53657/post-1948731 Am waiting to see if I can get better...

Pleased you are still with us!:) Best wishes, Rick

Anyone know if Erin has the new Dayton A400 amplifier in his queue?

Thanks for sharing! Not a huge surprise given Dayton’s recent history that these do not measure well. It is not that difficult to do better so suspect that is not the target market for them. As @Wolf suggests probably made more for the party crowd that is looking for something with some decent...

Happy to share!

Lol, at over 6 ft tall and 225 lbs., it surely could flatten! On its side, reminds me of a couple of gattling guns with some side cannons. With that bass peak, sure it has plenty of boom too. :)

It is America, isn’t more better? ;) The Moab struggles with low impedance so let’s add 4 more drivers and that should fix it!

Regardless of the designer’s appalling behavior, why does this Ulfberht monstrosity merit any consideration? Not that it matters as Amir is unlikely to deal with its size and Erin is not doing any more Tekton reviews. At over $20K, does not seem very competitive. Stereophile just reviewed a...

Thanks Amir! That makes 2 more measurements from you than the Tekton owner has posted for any of his speakers. :oops: If you consider my 2 sims of Tekton’s Footgate, makes 2 more sims than he has posted too!

Given how elusive EA is, 1 kHz could be intentionally deceptive. Or could refer to an acoustic crossover point. The electric one for the array was modeled on diyaudio and clearly rolls off well above 1000 Hz. In the end, it is one number in a complex crossover design for the array. The bass...

He does not do below 200 Hz you know.:) I find thick cardboard tubes easiest to adjust and finish. I usually flare the exit and have not found a need to do an internal flare Although my Purifi SPKs came with some, they are an unusual size. If you follow port spacing and location rules, it...

The beatings shall continue until morale improves!;)

Yes, the material properties in varying temps can affect performance. Reminds me to call out how impedance measures can vary based on voltage level too. For that matter, even though I have seen some decent correlation between speaker design software and reality, am almost always tweaking bass...

A simple way to see the difference air temperature affect can affect sound is an online wavelength calculator. You can set a frequency and pick speed of sound at 20 C and then redo at 40. :)

Equal is the rule of thumb case. You see the current state in post #22. The original SPK5 had a long twisty port and would not allow internal mounting of the crossover, The SPK4 calls for 9 inch port and is still too long, The posted impedance measures use a 7 inch port... Bear in mind the...

Yes, should add, that the original alignment is not a typical one. This was an SPK5 that I put the crossover inside and then had to rework the port to fit. This is what made it closer to the SPK4. More importantly, although my tests showed a shift in the box tuning due to the leaks, simply...

As promised, here is the response sim for the cabinet leak depicted in post #22.... In this case, this seems likely to be an audible difference. Some might argue that the leaky case may be better. Position within the room has a major effect and so is within the range of typical vented...

Modeled the M-Lore with a Eminence Beta 8 and, if you make the cabinet leakier and up the tuning several Hz, you get a comparable effect on its response just as @tmtomh showed earlier on Erin's Troubadour review... Note this is just an estimate as did not sim a potential crossover but can see...
