Im really after a more natural sound stage, live a live band playing infront of me !

Now while we are on subject theres somthing i need to get clear Mark.....

A valve Amp only produces a possitive push does it not? and when required a transistor negativally pulls back the wave to make a full wave from Polarity to Polarity?

Or is there just two Valves per push and pull?

Im sure some have a Transistor for negative pulling, where have i read this  :-/

Or is this somthing ive mixed up? or is this another kind of Valve Amp?

I doubt My Pioneers will make a good output stage over Valve Pre Amping ?

Correct, they were fairly average in thier day in reality.

But, its much cheaper to put together a good Mosfet output stage and use a single or double valve pre-amp setup to get the distortion valve sound you seek.


The clip is more a natural sound so i recall?

A nicer sounding Harmonic rather than a nasty square wave on a Scope!

Yes i have signed up on AV Forums.

I have a pair of 1972 Goodmand Magnums, there 7ohms each unit and are very sensative.

With just 50 wrms input im looking at around 30wrms to50 wrms a ch!

I have a total of three Pioneer Amps.

2x SA-540's and one SA-520

One will be running through a Receiver for Sub use.
the 520 runs my  Goodmans Magnums
and the other runs my Mission 700's in my PC room.

I do like the Amps but ive heard alot better.
I actually prefere the sound of my Mates Yammy natural sound on the Magnums.

The pioneer seems in some what a little harsh compared to the natural sound.

My plan is to run my receiver for bottom end only and the Valve Amp through the Magnums.

The Magnums have been stored for 20 years and are in awsome condition, there also the best speaker ive ever heard.

A good present from my Father in Law.  :)

1972 iirc!

Althogh in my house i have a ten inch sub in 2cuft tuned to 25hz off 75wrms .....now thats efficency  Grin

There's me thinking I like loud music - and I'm currently listening to a 20 watt valve amp. ::)

take the glove box out its so much easier!!

i found a wire coat hanger a big help when feeding the cable through the grommet  under the pollen filter


Doug

Yep. It's a long way to reach up to find that grommet without.

In fact, given that the need is for 70 amps and thus the cable is not going to be desperately thin, I would be inclined to drill and grommet a new hole for it.

As to which side to run it, most of the car electrics goes down the passenger side so that is where I routed the power cable. The driver's side sill is pretty much free of electrics (only the radio antenna + phone prewiring IIRC) so that's a better bet for any signal cables.

Kevin


A valve Amp is my choice over the next coming months!
 watts of Valve tho is a diffrent kind of wattage  :D

Utter drivel!

What parralel universe does this other type of wattage come from!

Valve amps differ in as much as when over driven they dont clip so hard......but they do have large amounts of 2nd harmonics (which makes them sound soft), average response, mega power hungry, stupidly expensive.....

I prefer a good Mosfet output stage with a single valve based pre-amp if its the valve 'style' you are after!

Much cheaper, more reliable, less power hungry!



Chill out Mark it was just a joke.

Meaning i prefere Valve Output than Normal Transistor Amplifictation  ;D

BUt within Car audio, USAmps make some wonderfull tube Amlifiers, although im into Car audio i think its a waste of time in a car sound deadened or not.

I dont care what anyone says you cant get 100 percent staging in a car! never mind perfect SQ.

Ide rather that in my House.


This is my Setup now



well...... a good few months back.
Only diffrence is now, ive got a Sub box and the cabeling has been managed!

Oh, and next time you see the Iceman,

say hi from Dave Watts & Sid Jervis


 ;)



I see  Iceman regular at shows and regular on the Phone TBH  ;)

Sign up on Streetbassers.co.uk and you will see most oldskoll chaps on there still!

Quite a few names I recognise there . .

Its been a few years since I last competed seriously, you never know, I may give it a go again someday. I have a load of old pictures from teh early days of competitions - might try and get them up on our website sometime.



That would be nice too see!

Yea i seen it on Big breakfst.

You will know some of my old skool pals

You proberbly know yourself, the old Audio control mic was quite a far bit out compared to the Term Lab.

My system hits 156.2 on the audio control.

All the guys back then and still evan now tune there vehicles high for ease of pressure and cabin peak frequecies.

The most popular right now is Fiat Panda's, there cabin peaks at 72 hz so its perfect.

Only problem with hitting big numbers at such lower frequencies is.... Its alot harder because you loose pressure fron door movement and screen flex!

Altough in the end before selling the car i was going to make a 25mm roof.

The Woofers i was using were actually an SQ Driver, tho they had an awsome x max and motor strength and power handeling, but in the Streetbass world they were always pushed to there limits and got thermal very quickly.........the smell of voice coil i here you say lol hell yes they stunk!

You should know Goeff ( aka firestarter) many vehicles
also there was Paul Coughlin ( Aka Mazdawg on the local forums.) he had then a Golf which did 170 db an audio control

Also Ian Iceman Pinder (Cortina)

Ray Harvey( BMW )

Got theres so many and i keep regular contact with them all.

Ive had a soft spot for Audio for many years, Loud music in the Astra was a big hobby at them low frequecies but now im consentrating in SQ in the Mig so i had an old 3 cuft box tuned to 27 hz and im going to us it.

Now im mainley ingo home entertainment.

Running Mostley old skool stuff.

Pioneer SA-540 (1980's ) Amplification for my old Goodmans Magnums (before was it akai that took over and they went crap)
Pioneer SA-250 running sub through also a 50 hz x over wound by myself! for the lo end.

My PC room i have Pioneer SA-540 running Mission 700 series Bookshelves.

Efficiency is king but i have a Woofer which has 36mm of excursion and a rather large motor structure so i need a lil bit of D class goodness to give it its Limits!

Althogh in my house i have a ten inch sub in 2cuft tuned to 25hz off 75wrms .....now thats efficency  ;D

Power Caps have never been in my Intrest Tbh , ive never gained anything.

You guys seen my old car didnt you?
2x 18 inch Resonant Engineering Woofers
2x Orion HCCA5000's (2.5k each RMS)
4x Hawker Powersafe Batteries (each batt weighs in at 47 kilo's)
110 Amp Alt.

Gave me 153.3 DB at 25hz!



























Evan tho this was built for competition and more so me having a soft spot for low frequencies.

This box was 22 cuft and tuned to 25hz with 150 inches of port area.

Did me well

This is my scores
