JBL 2226H 30 hz "horn" i built

[more10]

I have made a quick simulation using precision devices pd.186. It can be used from 20 to 40 Hz. System volume 1225 liters will be 1500 liters with material. The driver is in the same price range as the 15 inches. It will need 4 sheets of plywood. It will take 4 guys to carry it. You will need a truck to move it around. Good thing is that you will only need 200 watts to reach 130dB.

I'm looking at a 4th order bandpass and the 2226J looks like it was purpose built for the job, but If I spend 2G, or even $1,200, on drivers my wife will get the kids.

You missed out on the JBL Tent Sale awhile ago .. It was around $120 for a JBL 4648 bass unit (contains two 2226J) which the price includes shipping. I brought 2 units. The Cabinets was Huge.

The reason I built with JBL 2226 is because I have a few of them. And thats is beacuse I like JBL and collect their drivers. I did not use 2226 because it is good value for money. It is still a very good driver, but overpriced.

The Eighteen sound 15W700 is a much better choise if you want ferrite magnet. They cost new what JBLs cost second hand.

The Faital Pros are much better, but a bit more expensive.

After all, 2226 is a 20+ year old design. They should cost at most 100$ a piece, but when you try to bargain they say, well it costs 480$ new and I want 250$ for it. The only reason JBL can sell them for 480 is that there so many of the srx boxes. Every sold JBL driver is for replacing a broken SRX box. The only reason 2226 sell for around 200$ is because we pay that for them.

Curious which Faital do you like? They look pretty good, a bit hard to source here in N.America but not impossible.

FAITAL PRO 15FH500. Parameters very close to 2226, simulation on first page. These have neodymium magnet and somewhat larger (1.5 mm) xmax than 2226.

I havn´t heard them, so change my "much better" to "much more modern".

[JoshK]

that one looks good. Reasonable cost too.

The JBL 2265HPL is a different story. If I had the money I wouldn´t hesitate :-). Neodymium magnet, differential drive motor, excellent cooling. It is even cheaper than 2226!

JoshK don't think twice about Faital Pro I will be using them as soon as the plans are available, I think they are the best now from Italy built wise and reliability and sound wise. I have heard them in double 18" BR cabinet in Miami from a sound company last year for a Band/DJ show, it ran flawlessly for 18 hours continuously all night till morning (18XL1600).

FreeCAD is fantastic! A bit buggy but very very nice to work with.
