How do I use it with the Iwata-300 when the throat of the IWata is 2"??
JBL 2327 ... 2" to 1" adapter often seen on ebay.

Thanks for the responses.

How does the differing angles from these adapters effect the response?

The TAD 4001 and 2001 are Alnico-based drivers with a rather long, radial throath like the JBL 375. Due to the fact, that with Alnico - more length more flux.
The 2" - 1" adapter prolongs the hornstart with exactly the same flare.

Newer Neo-drivers are build to shorter horntypes and have a much shorter and much more angled throaths. I use the original Iwata with a 950, which has a 10 degree angle - but it is just about 10 mm. in length. With no sonically problems.
(Measurable, I don't know).

No personal experience with Radian and Truextent. Those who had both say little difference and BMS is much cheaper.

I was asking more about the wavelets and which one you deem to be a little better. There seems to be more ghosting at 5s for the 5490. Does that even matter???

Early reflexion in Radian+Truextent hides ghosting so we can't say for sure which is better. If I remember correctly TAD wavelets presented by Jean-Michel were cleaner. Take into account Radian with Truextent is 3x more expensive.

Do you have measurements of the Radian with the standard aluminum dome?
