Hi,

Looking for the best solution for a convertible shelf wedge box. Here are my targets:

- Must be 8" sub. Low mounting depth is a plus, can't be larger than 4.5" or so. 5" definitely won't work.
- Would like it to be available under $80-100.
- High sensitivity (90+db)
- Power handling of somewhere around 150 - 250 rms
- Good down to 40Hz or so
- Good in smallest enclosure possible. Maybe 0.6 ft max

The best fits I have right now are:

- JBL GTO 804
- MB Quart RWE-202
- Infinity REF-850W

The JBL and Infinity are basically the same sub (I think). I am comfortable with them, but I don't know about possibly better options. There is very little information out there about the MB Quarts...

Any suggestions are welcome.

I am currently using RF Stage 1 8" subs, and am not very impressed with them. Mostly because they have terrible sensitivity (83db), which is not a good fit for this application.

Tks.

 

JBL is an excellent choice. I had 3-15s in my truck, and i was very impressed with the sound.

 

it might be a little over your price range but i would get a jl audio 8.

 

jl audio, kicker, wow, too many choices here...

 

Resonant engineering RE series 8''. Best bang for your buck 8, ever IMO.

These are all very reputable brands in the car audio world. These are not ''mainstream'' brands so 95% of you probably havent heard of them, but these are the bomb. I have 4 RE8'' subs and registered 15db higher with the same power and box size/tuning as my friends 4 10'' Rockford P1s. 4 8''s compared to 4 10''s, same box size/tuning, same shop/meter, same power, 15db higher. Mainstream sucks IMO

 

Well if you're interested, I have 2 Sony 8" subs. 220 watts rms @ 4 ohm, only need .36 cubic feet of spacein a sealed box, .5 in a ported enclosure, 3 7/8 inch mounting depth, 87 db sensitivity, and good down to 30 hz. I know they don't have the sensitivity you're looking for, but I'll give ya one cheap.

 

Another forum member was nice enough to point out that some manufacturer sensitivity ratings are a sort of average including in-car reienforcement. So the RF subs are not quite as poor in this respect as I originally thought.

For the time being I think I am going to do some work on the enclosure and see what I can get out of them. Whatever the case they are still not a very good driver for my application, though.

Thanks for the suggestions thus far. Wish I wasn't stuck with using 8"s...

 

You may not be stuck. Take a look at the Pioneer Premier 12" shallow sub (I think DS12, but can't remember). It's basically an iso sub in a single basket. Not the best sound quality, but I put three in my Magnum because I needed 4" or less mounting depth too, but wanted big sound. They handle the power and I was impressed with the response. Maybe need .3-.4 cu.ft. per sub (sealed).

 

Thanks for that, I saw those, but diameter is also a problem. I'm using a wedge box in a convertible and 8" is all you got to work with.
