s1s-ex vs 4645c

[leif]

Anyone have any opinions about these two subs?
They both use the 2442H, and both enclosures are 225 liters.
The price here is Norway is 3 times as high on the s1s-ex as the 4645H.
Are they actually equal, exept for the finish? (and that one have 3 ports, while the other has 1)?

I would use the cheaper one myself

This was discussed elswhere.
The 2 units are the same (except design).
The one is professional and therefore has a reasonable price, the other is synthesis and therefore has a not reasonable price.

The S1S and 4645 are functionally equivalent - the ubiquitous 8 cubic foot volume tuned to 25 Hz first started way back when with the B460.

There are some S1S's and 4645's out there in the field with 30 Hz tuning frequencies instead of the 25 Hz tuning frequency. They usually use the older 2245H instead of the newer 2242H. At one point JBL was trying to keep 2245H's from blowing up left and right so they changed the tuning frequency upwards 5 Hz. When the monster 2242H became available they went back to the 25 Hz tuning frequency.

The S1S-EX uses the 2242H in a 6.5 cubic foot volume tuned to 25 Hz using three 4" flared tubes.

3 times for the same performance

the 4645c is a bit larger in volume but it si slimmer

4645c H1010 x W67.4 x D45 = 225 liter (internal)
S1S ex H87.6 x W53.3 x D55.9 = 185 liter (internal)

it an easy decision here

but then why the smaller but deeper enclosure

for installation in rooms deeper has more problems than slimmer designs

4313b Is there some adjustment done too the volume too work better in small rooms?

4645c was intended for large spaces

there must be a way to the smaller but not so practical enclosure

I too am interested if a smaller size cabinet(but tuned higher) that could be used in a smaller room.

The only difference for me is not needing response below 35hz as my room nodes go crazy below that. So the tuning for my scenario would be higher than most folks need for a larger room!

As for the ports on sevreal of the JBL 46 sub bass model range some have two ports like on the JBL 4645B they bend inwarads at 45 degee angle. The sub has nice deep low end shake n' feel.

thanks for your coments

The 1500 Array would be my choice if cost were no object

mine too (design i like more the hb5000)but at the moment cost is factor
especially if you think in buying 2 units for better in room bass

but i think my 2 b460 (2242) clones in my specialized music room should do extremely well

I've been told that JBL has since come up with a new eighteen that behaves more like the venerable 2245H. I can't remember the model number right now.

maybe in the near future

Maybe stereo sub bass!

No doubt

The characteristic that jumped out at me when I heard my first pair of 2242H's was how incredibly clean they sounded.

The characteristic that jumped out at me when I heard my first pair of 2242H's was how incredibly clean they sounded.

When I had a pair of 2242H in 9 cu ft cabs in my living room I was using a single PE sub plate amp (250 watts) and never came close to tapping the wattage.

My WT2 measured approx -3db/35hz, but pipe organ music never missed a note!!!


In my 12' x 16' room I feared structural damage if I continued to run them on a regular basis.

I now have a pair of 2245 cores that were reconed to 2240H's and plan to try them out in 6 cu ft box sealed run off a McIntosh MC-240 and using a Reckhorn B1 to control the bottom end. It has a variable HI/LO pass filters and a variable EQ.

I'm just researching the resistor network to pad down my main amps speaker output and reduce it to line level for input to the B-1. I don't have a pre out/pwr in on my integrated 300B amp. Also, the B-1 has a input impedance of only 10K ohms which would kill a tube preamp looking for a MUCH higher input impedance.

I look for room gain to fill in the rest.

That project will be a few months down the road as my throat surgery next Monday is center stage for attention right now.

Hey, Ron,

Best of luck in your upcoming surgery, Sir! Get well soon, so you can continue singing the praises of the things we all love: JBL goodies!! I still have not yet played around, too much, with my 4645 cab & 2242H woofer. I got sidetracked with a horrible hum in the system, and have yet to track down the source, though as Bo so wisely suggested, it's probably my H/K preamp. Again, please keep us posted as to your recovery after the surgery, and we'll keep you in our prayers and thoughts. Take care, and God Bless!

Every Good Wish,
Doc
