Scanspeak 23W vs JL Audio 10W7?

[topher_m]

Hi

I am going to build a set of subs to accompany my line arrays. I am only interested in music so I am thinking of going sealed.

What do you think about the JL Audio subs vs the well regarded Scanspeak 23Ws?

The JL Audio subs like the F113 and the Gotham have gotten pretty much universal praise also.

They are about the same money. I am thinking of 2 x 2 for a total of 4 units.

Small size is pretty essential considering the line arrays are already huge. So the Dayton RS HF series is out - good reputation but requires huge box. Also means most 15" are out even the high BL designs.

Mostly my question is in regard to linear output capability. Both are capable of going in a small box but the JL is a 30+ lb driver vs a 10 lb driver. I know that comparing just on weight is silly but doesn't the higher weight imply a much stronger motor which implies higher output capability in a small sealed box.

Any thoughts?

Other experienced suggestions like the new Morel subs are welcome. Overall budget is ~$1400 for drivers in small 1-1.5 cu ft per driver boxes (in other words, 2 drivers in a 2-3 cu ft box). Only SQ matters, not crazy thumping HT output.

The 23W has the ECA of an 8", with 12mm xmax. The design is all about getting down low in a tiny box.

The 10W7 is a 10" with 23mm xmax. Thermal power handling is also higher. No doubt it's displacement and thermal limited SPL will be higher.

Have you tried modelling them in Unibox to see how they fare
in equivalent sized enclosures?

I'm currently building a sub with a 23W in a 37L enclsoure, which I'm going to drive with one of Anthony Holton's NX150 modules (275W into 4R). From what others have said the 23W needs LOTS of power to drive it (pretty inefficient, but with 4 shoud get better spls), but it is meant to sound very good. Probably depends on what you are matching it with - mine is to go with Ellis 1801b, crossover being the Borbely all-fet.
Probably a month away from powering up (crossover finished, amp finished this weekend, sub a couple of weeks away from completion). If you haven't decided by then, I'll let you know what I think.

Which 23W, the 8861? I thought it required a box that was almost twice as large (70-75 liters). Even the 8565 requires about 70 liters.

I was thinking of this aurum cantus woofer for 35 liters?

but it's Fs was a bit high.

I have a 23W driven by a Bash 300 and it poops out if you are trying acheive HT SPL's. These need to be used in multiples as the woofer is very small and the excursion really isn't much. As a sidenote the sound quality is excellent.

what is the box volume and type?

How about 2 per channel for stereo.

[chrismercurio]

It's ~1.5 cubic feet and can be sealed or ported. Right now I'm running it vented as the driver does better. 2 per would be MUCH better.

Selah Audio makes some dual and quad subs with this woofer....

I did check out the Selah site and I think they are mostly using the 10" Aurasound woofer and 12" Peerless XXLS. I am looking for a compact (sub 70 liters) sub that can produce 100db at 50Hz and keep pace with the best 5" midbasses (read as SS 15W or Seas 15cm magnesium) XOed at abut 150Hz.

[chrismercurio]

150hz seems really high to cross a sub...

It sounds like you want a woofer. In multiples of two or more, the 23W will do what you want in the size box you want. I don't know what distance you want to recreate 100db from, or how large your space is, but it is a quality woofer, at a very high price.

I intend to have stereo woofers or subs. one under each satellite sort of like a WATT-Puppy.

100db at 1 meter for 1 speaker should do. If I get 95db+ at my listening position about 3 meters from each speaker I should be ok. I dont listen too loud but really like definition.
