What to do with 2435 and 2202H ?

John W:

How big is that cabinet for the 2245 ? ?

EDIT: oups, I didn't read the question properly: it was related to John W's clone directly. Sorry.

two times that of a 2231/2235

but you can also go smaller:
- 140L will be enough for a sealed box
- 220L will be good for a sealed box, and also acceptable for a ported one (with the option to tune it lower and add some EQ or resonant high pass on the tuned frequency, as with the B460)
- 250L will be good for a ported box (4345)
- 290L will be even better according to Greg Timbers himself (I don't thnik he mentioned an exact volume, but he stated that the 250L of the 4345 were not quite big enough)

The outside dimensions of these cabinets are:
28 1/4 x 45 1/2 x 18 inches
or 71.8 x 115.6 x 45.7 cm

The dog box needed for a 2202 is fairly large. I don't have the exact dimensions right now, but when thinking about a design you need to keep it mind if you build just one box.

Maybe an Edgar Horn should do it or do you have a suggestion ?

When reading about T/S parameters for cone transducers used with horns I realized that the 2202 is close to perfect for horn use.

Since I have a pair, and I have been playing with the idea of bass horn for a long time, the T/S parameters was entered into Hornresp. A quick sim is shown in the attached pictures. It is huge though.... 1.5m3.

Hi John (and the rest of you)
I also have 2202 lying around that I would like to use for midbas/lower midrange. But I really would like to know the box size needed for it to play down to 300hz where I would have a 2225 to take over. my total box size is 210 litres.
thanks

Here you go. Use Win Isd

Hi guys

Im slow but i think i have an idea of how my system should look like

My system will be as follow:

2435 HPL in Smith horn 1000Hz-
2202H in 35Liters closed cabinet 120-1000
2235, 2242, 2245 or 2203A from 30-120Hz

I need some input on my choice of LF driver....What driver should i choose and why ??

I will soon put up some pics on Smith horn and 2202 cabinet...

The 124/2203 is a really nice driver, very fast and powerful but limited xMech. It won't keep up with a 2202. The LE14 won't either.

The 2235H is nice if you don't have room for an eighteen.

The 2242 isn't quite as effortless on the very bottom end as the 2245 but it has a very clean sound character and it handles unholy amounts of power.

The 2245 has the most effortless bottom end of the bunch and it is very articulate. It is a true very low frequency transducer. The LE14 is a close second but it doesn't have the efficiency.

Is it the lack of power handlig that make the 2203 dont keep up with the 2202's ? Is that really a problem if im not planning to play 140 db ?

It's the efficiency difference. JBL used two 2235H's to keep up with the 2202 and that's with bi-amping. You can certainly try the 124 or 2203 if you want but I would argue against searching them out if you don't already have them. If you're sold on the small size of the 124 or 2203 then use the "better" LE14H instead. It doesn't have quite the punch but it's better balanced and sounds really nice.

Im getting confused...2203 has 93db and LE14H 91db...

[4313B]

The 124/2203 and the LE14 had roughly the same sensitivity of 91 dB, 1W, 1m.

I ran into TAD TL-1601B so ill try to use them for the LF

Nice woofers.

You should know but why didnt you use them ?

[matsj]
