They provide an adaptor for 1.4", perhaps they'll make one for 1", as well.
EDIT: Their site says they have a 1" reduction piece.

I've seen adaptors for that, but a couple of questions out of curiosity:
  • Can you really go low enough with that 1" driver to take advantage of that Iwata-300?
  • Is the Iwata-300 available with a 1" throat?

If the answer to both questions is yes, and you'd rather get the 1" version than use an adaptor, I'd be very interested in your Iwata-300s!

The Pallet is in the US but I do not have the Iwata-300 yet. I have no idea if the Iwata-300 could have had a 1" throat, its ordered and shipped with a 2" throat. I was going to use the BMS 4590p CD they are around $700 each right now



I had a thread asking about 2" CDs and requirements of 500Hz. Someone posted that with a steep slope the TAD can go really low.

I also have 1" QSC waveguides so the TADs are going to have a home no matter what but I wanted to try them with the Iwata-300 when it arrives.

I did see a 2" to 1" adapter on ebay that might work.

Anyways, I wanted to know if autotech has a perfect adapter for the IWATA-300. On the website they say there is a 1" reduction piece. I guess I have to find out how much that costs and get it shipped from Poland.

Conical adapter or new planned BiRadial (similar to JBL 2345 and TH4001).

This is a way too much - more like 400$ here in Europe. Will ask for adapters...

New Matlab routines from Jean-Michel help print measurement data. Below SEOS-15 with 4538 equalized to 22.5deg. Result - smooth power response.

Well at almost $1.50 exchange rate and shipping that puts the $400 at around $650 US.
