I feel a tad dodgy/ghetto with my addition to the DIY community, the other day i got given a massive sheet of 18mm MDF that ive ripped up rough as guts over the past couple nights.

i modelled the cab in hornresp with an Alpine Type S car sub (12 inch) in Jbells SS15 and simulated some decent usable results.

i will post up some pics of my rough as anything freehand box over the next day or two and will also find myself a chance to really crank it up to see how it sounds, but already at low volume, and barely sealed up, gaps everywhere, it sounds quite deep with a distinct peak at about the 50hz level where it was buzzing all my outer paneling on the house. (it was outside at this point)

im buying some "vice" branded PL gule today, so will be pulling it apart to seal it all up, and will be taking pics along the way.

its bigger than i expected it to be, but not so big its unmanageable like my dual15 box is currently.

i cant wait till im able to build the proper pair out of PLY, with proper straight and square cuts.

very impressed Jbell.

well i must say! !!!WoW!!!

this is my "dodgy" one, with the technically way "wrong" speaker and severely underpowered.

seriously, BASS im in heaven! if i had found this site before i built my sub cab, i would have saved so much time and effort and heartache

the SS15, for a single sheet, "relatively" small cab, and with an underpowered car sub in it, already sounds like it has way way more bass and projection that my twin 15 PA sub horn!

one thing is for sure, i need to get myself an active inline sub controller for my currently inactive 4x300w amp for it to run my soon to be 4 SS15 cabs.

here is one happy customer.

How does the actual output of the SS15 compare to one of the 18" passive commercial subs, like the Electro-Voice ELX-118? EV boasts of a peak output of 134dB from that subwoofer...

Well I'm sure you know, you can't always trust the marketing claims. Unless they get very specific with the claims, I'm sure that "peak" number is calculated and not actually measured, then again I'm sure it is also calculated in half space not full space, and at a high(ish) frequency.....

Oh, I'm pretty certain of that .

I'm just interested in finding out if anyone has had the opportunity to compare it to one of the "commercial" sub solutions, like the EV I mentioned.

Why? My brother is looking for new subs for the night-club he manages. He's leaning towards 4 of those EVs. I've been trying to convince him that building the subs may produce better results (my cousin, who owns the club, is great at joinery, so building a subwoofer box should not be that great a challenge).

I think unless there are space constraints, or the club plays big hair band rock exclusively you should be going with some bigger stuff that goes lower. It's not too hard to get to 140dB down to ~30-35hz with 4 big boxes and an amp or too. Might be overkill but if your gonna build don't go lite on extension or headroom.

This is what the response of the ELX118 looks like:

After loooking at the data sheet for the MTL-1 I'm sure the plot is for just one. I bet the response fills in as you line them up side by side. Anyone have drawings and specs for the drivers? It shouldn't be very dificult to DIY a better clone...
