Bass in mids question

SYKO · Postby **SYKO** » January 29th, 2019, 7:58 pm

Fellas i crossed my mids (b&c 8pe21) between 500hz and 1200hz but getting distortion when i raise the 50hz band on my preamp. Any suggestions?

What you using to set crossover levels? Head unit or amp??

500hz boy, yuh wasting d speaker inno

Using the amp. Everything flat or off on the deck. Thing is, is trial and error in getting the speaker just right especially at high volume.

i presume something is connected wrong 500-1200Hz is a super small bandwidth and I am pretty sure will not sound pleasing

u say deck on flat & u using d amp to play d speaker at 500hz to 1200hz - i guess ur not using a crossover so d amp has bandpassing abilities ?

what amp is that ? , how do u know its actually being played at that range u hoping for ? ...

Ok guys, my bad it was 500hz - 3000hz. I double checked it. And yes its no external crossover. I bandpass the mids using the on board crossover. Amp is a SS TN4.900D.
I really wanna start the speaker at say 250hz but at high volume that 50hz messing me up. Only processing i have between hu and amp is a massive eq7. Will be changing that to a db drive speqp as i got it online real cheap.

Not even this. The newer lower end pioneers are cheap and have great DSP capability, similar the the PRS but not as extensive as.

Guys straying from my topic a bit here. My mids amp is a soundstream tn4.900, with a pair of loudforce drivers and a pair of B&C 8".
Currently wired
Ch 1 - driver
Ch 2 - driver
Ch 3 & 4 bridged - speakers.
Is this ideal to get the most out of the amp ?
Or shud i do
Ch 1 & 2 speaker and driver (with resistor)
Ch 3 & 4 same?

since no sub on the amp & u eh say what b&c 8"
wire b&c's in parallel to ch 1-2 bridged with a 22uf condenser.
same wiring for ch3-4 with the drivers, but only if in parallel they not below 4 ohms.

how much more ole noise u want , i wuda leff it as is ...

88sins · Postby **88sins** » February 2nd, 2019, 4:22 pm

plenty lol
don't hadda constantly ring out, but it good to know you can if you want/need to. as long as the whole system tuned and set properly a lil noise does be nice sometimes

Its the 8" pe21. So basically switch around the wiring and add the mentioned resistor. Will play around with it and see. Thanks

np just keep in mind to not crank the gains on the amp all the way up & mind your crossover freq. settings.

As an additional step if you can, to try to match your signal voltages as evenly as possible, idk what sort of signal processing system you using (crossover vs preamp eq) but some units give you the ability to adjust their output voltages. if yours does allow for this, try to keep the voltages of your head unit & signal processor as evenly matched as possible. This helps reduce the potential for distortion & electrical noise at higher volume levels. providing you use quality components.
I personally prefer to go with a max of 50% of the HU vol for this with the HU eq set on flat, but I know that some ppl that do this go as high as 75% of HU vol.

Rovin · Postby **Rovin** » February 4th, 2019, 6:32 pm

^^^care to explain that HU vol 50% suggestion , what u leaving back d remaining 1\2 of d vol level to do ?

find a reputable shop with a O scope or SMD DD1 to set ur gains , for crossover points : SMD CC1

or there are numerous vids on youtube on how to set gain with a DMM

as for setting ur EQ : u set it to ur personal taste , try not to over boost stuff ... imo : less is more
