Some of you may remember an earlier project of mine which included a JBL
2242H in ~8³. After testing in a temp box to make sure it was the type of bass
I wanted (it is, and then some) I started on a permanent box for it.
This is tough for me so Ill just blurt it out. I dropped the driver and ruined it.
I rushed it to the hospital (JBL Northridge) but I was too late. Apparently the magnet shifted and was now destined for doorstop duty.
Im still a little miffed that the company that makes these couldn't repair it.
Anyway, fast forward a bit, of course now I cant find any deals on 2242h's.
I noticed that John recently came out with an 18. I talked with him for a bit and it looks to be a drop in for my application. Wrap it up, Ill take it.
The TD18 has about five more mm xmax than the 2242 but has quite a bit less xmech. It has a 2.5 inch voice coil compared to 4 in on the JBL. John says the Lamda motor dissipates heat as well as or better than most 4 inchers however. We shall see.
One thing I didnt expect because I never saw any pictures of the driver, was the giant phase plug (?) It is stationary and the cone moves over it. Maybe John will weigh in on this as its not mentioned on the product page.http://www.aespeakers.com/news.php?start=0&news_id=20
I left the box halfway done in disgust back when the driver broke, so I have a little work to do before I fire it up.
