high spl satelit speaker

[panduro]

Hi all,

im going to build 2 front satellite speakers for my small ht.

it needs to cover 80/100hz and up. below 80/100 subwoofers will take over.

xover and eq will be done actively by a dbx pa+.

high frequency wil be handled by a jbl 276nd, basicly a jbl 2426 but with horn mounting via 1-3/8"-18 male thread.

subwoofer drivers: jbl le120h(got 3 of them)

thats what i already got for the project.

but i need a midbass/midrange driver to cover from 80/100 to about 1600-2000hz.

i would prefer a single 10 inch driver with high sensitivity and a high powerrating, that needs 1,5 cubic feet cabinet or less.


what would you suggest?'

best regards

how wide is your horn??

2123 / 2012 ( 10 inch ) would work well. I have a number of the 8" 2250HPL mid woofers that were designed with an integrral sealed back but might work well in about a .5ft3 box.

Hi Sub
Would you also have 4" phase plugs for the 2250H ?

thanks for replying to my post

my horns are jbl 73150, looks like the jbl 2370A, dimentions are w x h x d 14,6 x 5,2 x 6,3.

I wanna change those for something a little less horn and a bit more waveguide. i would like them to be "same" size as the midwoofer, but can go a bit bigger if necesary. Why? and do you have a good suggestion?

Jbl 2123, does that driver do well all the way down to 80/100hz, i had the impression that i woudnt go below 200hz?

jbl 2012, well both drivers look like the fit my wishes very well if the are good down to 100/80hz. differences in the sound from the two??


best regards

I love and have used the 2123 and the 2020 in many systems. My favorite combinations when aesthetics are included in the equation are the 2123 with a 2342 or the 2020 with a 2344.

Neither the 2123 or 2020 drivers speak with authority below 200/250Hz in sealed enclosures to my satisfaction. I have 2020/2344's in my office at work and my bedroom at home with subs and they can be leveraged to sound pretty nice but sound far better on top of a 15" if you want them for more critical listening than background music or to play them loud. Maybe I'm doing it wrong, who's to say. That said I think many who have become accustomed to the sub-sat sound just don't miss the midbass or have forgotten, most sound week to me, but is something with a 12" in it really a sat?

Sometime ago I think one of the Rob's here posted something about a vented 2123 project tuned near 80hz, maybe for a car project?

All the best,
Barry.

Hi Barry,

i did read about it, but dont think it was done.

reason for me building a sat sub system is that my room are to small. bass speakers in the corners, not good.

so i need something powerful that will do around 80hz so i wont notise the xover to the subs as much. will make 3 new sub cabinets so i should be able to get a uniform basresponce even in my small room.

the 2020, how high did you cross it over to the tweeter?

best regards

if you want the satellites to hit 80hz then you need to use high-compliant woofers. playing tuning / porting / etc games with pure midrange cones to get usability below 200 or so is not worth the effort or design compromises.

The horns are a little too wide ( they are the model 2371 ) and like mentioned, the 10 / 2342 combo looks very nice and your 2426 can thread to it.

perhaps a pair of LE10H woofers or one of the variants would be best.

BTW - nogo on 2250 phase plugs but I DO have the fitted back cap/shrouds.

Why not go with a 2206? It'll make 80Hz in the right cab... is quite sensitive, and can take a lot of power.

I am surprised nobody mentionned the 8" 2118. It would easily go down to 70Hz in a small size vented cab and up to 2KHz And it can take a lot of power (for its size).

I guess we have different definitions for "high SPL".

There is an old thread here somewhere in which a member showed his diy HT speaker systems using 2118;s and the Dr. Suess horn, which is a threaded horn, as I remember.

[speakerdave]

The horn is more properly called the OASR, still listed as available last fall:

[speakerdave]

Actually, he used the 2206 for all speakers except the center channel. It was Woody Banks, and here is the thread:

Considering what is needed, is anything more powerfull really needed?

Don't know... I don't really need high SPLs, but if I did, I'd want much more than an 8" woofer.
