I'm looking for a 12" sub to run in a sealed enclosure.  I want one that 
has a low Vas and an Fs in the high teens or worst case very low 20's.

I'm going to use a sealed box and pump about 100 watts into each one.

If there are any 10" subs that also meet these requirements, I'd like to 
know about them, also.

Any recommendations would be appreciated.

No can do!  The PQ8 is not bridgeable and it cannot be used
mixed stereo/mono.  That's what the manual said anyway.

However, the circuit diagram quotes, "bridge switches shown in
off position" so maybe it is bridgeable if you mess with it
internally.

I have the manual if you want to pick it up some time - I forgot
to give it to you.

Hi there.  I am thinking of adding a subwoofer to my system.
Right now, I have a Pioneer pullout, 6 disk changer, Sherwood
(I think it is a 1240q or something), Infinity 602 door speakers, 
Yamaha sealed box (two 8" drivers, 2 horns and a 10" or 12" passive
radiator downfiring).  The problem is, when I really get thumping,
the radiator throws so far that it hits the bottom and makes an awful         
thfffpt sound (Yes, like bill the cat).  The woofers dont seem to be
over throwing, but the radiator just hits the bottom.  Would it help
to somehow run a crossover to filter out the real lows, and send them to 
a dual voice coil MTX 10" sub?  How would I go about crossing it over 
and building the box?  Theres not much room left in my car, I have
a ''78 mustang II, and the Yamaha takes quite a bit of room.  Also, 
would it put an extra load on the amp, or make it quieter?
I consider myself an amatuer radio installer, but I have put my whole system   
in, so I'm at least a very good amatuer.  Any comments and EMAIL welcome.
Oh, btw, I have the head unit powering the infinity's (25x2).
Thanks Much!

I think the problem may be the lack of a SOLID mounting surface.  To
maximize the CD player's internal damping, you basically need to make the
player a part of the car (i.e. bolt it down so that it's not going 
anywhere!)  unting in the glove box is not secure enough.

I've had both an indash CD and a changer.  If you make sure they are
down well enough, you shouldn't experience any skipping.

It tends to be very hard unless you are driving the speaker with more
power than it can handle or you send it just one tone for so long that
the voice coil overheats.

That kind of power level is unlikely to ever cause problems for either
C-12s or F-12s from Stillwater Designs.

And they are also probably trying to run as much current as possible
through an array of subwoofers that have a very low impedance.  There
are some trade-offs here, and the equipment needs to be high-quality to
handle these kinds of situations.  The ability of the amplifier to damp
the movement of the voice coil diminishes rapidly as the impedance of
the driver array goes down.

Good question.  I dunno.  I've only damaged minor pieces of equipment,
like fuses and connectors.

There's nothing shameful since that's probably better than your stock

There's some damage you're overlooking... your ears! :)  I wouldn't

  Hello!

    First off, I would like to thank all of you that gave me some reviews
    and input on the Pioneer Supertuner IV's!  Mucho appreciado!!

  Now, onto our next question.....


  My dad has an MX-5 Miata with the factory am-fm/cassette deck, and wants
  to add a cd changer to it.  He said that he heard that there are inputs
  or controls or something for it already.  

  Is this true? and, What do you all recommend.

  Personally, I told him he should get the new Pioneer single/changer model
  with the new Supertuner.  (He wants a cassette deck, but I don't think 
  they have one with the new S.T. IV- or am I wrong?)

  Thanks in advance for your ideas!

  later...

   I've often thought about such a design, but the problem with
   adaptive filters is the compromise between speed of response
   and convergence accuracy.  Too far either way and the effects 
   are audibly unpleasant.  However, it is not inconceivable to 
   have the parameters measured and set at installation time, 
   where the adaptive convergence trade-off can be tweaked.

Exactly.  What Louis is talking about is how long it takes for the system
to hear the 'noise' and modify its output.  You really don't want the
system to instantly compensate for every noise it hears.  Imagine driving
down a gravel road, or worse yet, imagine the system instantly boosting
4khz by 20db cuz someone honked at you.  You want something that can take
calculate the current 'noise floor' and compensate for that...

Yes, what could be done is a measurement of your car's noise signature.
A complementary response curve could then be programmed in.

Of course, people are actively developing this as I write, so no patents
here :)

   Besides, people bitch about a $100 equaliser, would they go
   for a $500 (my guess) DSP box?

as chuckles fill the room, a scrawny hand in the back is raised and a meek
voice says, "I'll buy one."  ;^)

But it'll definitely be more than $500, heck you don't want to know how
much my DSP cost, but it does have Dynamic Road-noise Cancellation (DRC),
basically two preset EQ curves that it uses to compensate for the noise it
hears...

I don't know whether or not this was a flame.  Can't tell.  I'll assume it 
wasn't. (graciously)

But seriously, I'm talking about a variable response curve to match the 
ears response at variable volume levels.  How possible is it to do this 
cheaply?  Seems like if you could build one yourself you could get some 
extra points in an IASCA competition.  I know that this is somewhat like a 
loudness switch, but what I'm thinking about would definitely be a neat 
improvement, IMO.

Article-I.D.: yukon.1992Apr12.195643.9625
Organization: Yukon Technology

I just bought a new Subaru Legacy wagon and would like to install a
CD changer in it if possible.

The car came with a very good (my opinion) cassette / radio and according
to the brochurefor the car, a CD player could be attached to it, but the
dealer wanted something like a million dollars to put one in and wouldn't
budge on the price.

I have a JVC changer in my home and would like to install a changer which
uses the JVC type of cartridge if possible.

I haven't had much experience with car stereo in the last 10 years or so
and the following questions come to mind:

*  How do you connect an after-market CD changer to my radio and how does
   it work (Do I have to throw a bunch of switches and stuff?).

*  Where exactly does one put a changer in a station wagon and not obstruct
   the cargo area.

*  Are CD changers that reliable?  Does anyone reccommend one brand over
   another?

If you have any recommendations, please email me.

Thanks,
