The 2226H might be difficult to substitute for in front loaded designs where the driver's top-end performance is being tasked. As a sub, even in ported systems with a 40Hz cutoff, you could probably get more performance for the money without much trouble. If you're going to cut off above 120 or so and want to go down to 20 you're probably throwing money away. But the OP doesn't want to go below 40 and just wanted an enclosure. Nothing out of whack there.

Well I can't type anything here and prove to anyone that JBL is the best, but I can say that they are widely regarded as the authority on 15" cone transducers since before the D130. Their experience, engineering, and quality control are first rate. Their tolerances are tighter. Their 15" pro units are the most reliable.

The great Kappa driver you mention uses a copper VC. The JBL unit uses flatwound aluminum ribbon which saturates more efficiently while weighing less. The magnet is larger yet the moving mass is less. The xmax is greater.
The frequency response is much flatter on the top end, allowing simpler crossovers at the roll-off. Overall distortion levels are lower. Power compression specs are better. Impedance at resonance is lower. Driver masses lighter. Xmech is more than double = less likely to fail if abused. The JBL driver cools more efficiently, again making it the more reliable driver. Many of these things make the JBL a more accurate = sounding better driver.

You get what you pay for. The Kappa is great. But the JBL is better. It sounds better. Millions who use them swear by them. I wonder why. That said, I would buy the Kappa as its price is more attractive and it's a great unit. But if only the best will do, I know what to buy.

Like I said, this customer is sworn to JBL, so I cannot deviate even if I wanted to, but from the discussion, it sounds like it is not a bad choice. The only question seems to be the driver choice, but I really cannot see that this driver is a midbass driver like was mentioned??? I am really inclined to use this driver in this application, but I am a little bit concerned if I will have a problem with how it will perform in the vented design that I am going to use, which by the way will be about the same airspace, but maybe tuned at about 38hz. Thanks for the replies so far too...

Hi

IMO, The JBL2226H-8 in a compact T-TQWT enclosure would be a good choice for a quality sub.

BTW, the best pricing I have been able to access is from Parts-Express on JBL drivers and Crown for that matter. Where else should I be looking at? I can't find the 2235 drivers mentioned there however.
Thanks again for the help

Yea, I wouldn't recommend using the 2226 below 40hz in high-power situations. It's not its application. The Exodus woofers are real subs and you can EQ the crap out of them to 15 hz if you want. But they are big heavy cones. The JBL will walk all over them from 40-200hz; providing the cleanest, tightest sound available.

What is your budget for this project? You should consider JBL 2242 as DJK says if you can afford it. The JBL TCB box for 18s is the 4688 and the box for 15s is 4685. Here are the links:
