[nervewrecker]

Id say the memphis....but why you need it with a pwm20?

Didn't you ask about which is the better preamp sometime recently OP?

Hello,

I'd opt for the Memphis crossover over the clarion.The major reason is because the Memphis can "band pass", meaning your mid-bass woofers would play between two frequency ranges, allowing for maximum efficiency in that range.One thing to note, would be that the low-pass for your mid-bass isn't the the high-pass of the treble.This now allows for a bit of frequency overlapping, which would hide away the crossover points, making them not very audible.There is also the option of switching off the mid-range/mid-bass low-pass, thus creating a high-pass only.

It also has 18db per slope high-pass network and a 24db low-pass network.The clarion doesn't state it's crossover slope,but in cases like that, they are usually 12db or 18db per slope, so there's a more than likely case of the Memphis being much more accurate.

The Memphis states seven volt maximum output line drive(average of 3.5vrms), and the Clarion, a smaller five volt max(average of 2.5vrms).

The Memphis has several advantages over the Clarion, and has all the other features the Clarion offers as well, so the winner is more or less clear, the Memphis 16-x03 gets my vote.

Thanks,

great info from ADT always....2 thumbs up guys...

Team ADT, you is ah bawse...real good info and advise to the op...

Hello, thanks for your pm OP, here's your answer-



High pass- The speaker will play from here and above
Low pass- the speaker will play from here and below
Band Pass- the speaker will play within the set range of a combined high and low pass

Octave-
There is no set perfect value, but it's a change in multiples or two, and negative multiples of two.( a 1000hz 18db per octave would be a 18db suppression between 1000hz and 500hz)

18db octave crossover-
This means the value of the selected crossover point would taper downwards by 18 decibels per octave.This also means that it introduces a 270 degree phase shift.

24db octave crossover-
This means the value of the selected crossover point would taper downwards by 24 decibels per octave.This also means that it introduces a 360 degree phase shift.

The reason you're switching the input on the crossover to "mono" is simply because music in it's dynamic nature may have front and rear fading.This will merge the signals to create one consistent output, equal in all aspects of left/right and front/rear.

Switching the sub input on makes the sub section take signal from the subwoofer input and not the front/rear inputs.

Phase switch should be set to 0 degrees, please note there was a mistake in my diagram with regards to this!!!!


By switching on the "mode" switch to "band-pass", you engage the low-pass for the mid-bass, so the speaker will play from this set frequency to the set high-pass value.EG. if your high-pass is at 90hz, and your low-pass at 1.5khz, the speaker will play between 90hz and 1500hz.

By switching the "frequency multiplier" switch to "x20" you simply multiplied the set high pass for your drivers by 20 times. EG- 50hz set at x20 would be 500hz.

These sharp crossover points may create audible gaps in your system, so they need to be overlapped accordingly.I can't give you your crossover points yet, I need to know what speakers and drivers you are planning to be using in order to select this.


Thanks for the questions,

team adt thanks again i wud be using 2 d3305ti an 2 rcf 10'' and 4 10'' powerbass

one more thing wtk if to use d hpf from d deck an both amps

drivers - powerbass 800,2
rcf - db drive a4 pro 3600
powerbass 10'' - powerbass 1500.1

[TEAM ADT]

Hello,

You don't need the hpf on the head unit.I would recommend a good 15-30 band eq though.

You will need separate amps for your mid-range system.Use the db drive for the RCF, and the 800.2 for the drivers( I think this may be a bit much, be careful though).The Powerbass 1500.1 is a great amp with good performance, it will match nicely with the four tens.

Here's your crossover points-

RCF- 90hz high-pass, 2000hz low-pass(place these in a ported enclosure, if possible horn loaded)
3305ti- 1.25khz high-pass(place as close as possible to the mid-bass)
Sub-woofers- 100hz low-pass

Please remember to set all amp crossovers on "full" or "off".This will allow the external crossover to do it's job effectively. For the mono, set the crossover point anywhere above the external crossover's point.

Thanks again,
Team ADT

Other than the bandpass feature, what features does the external crossover possess that my amps (generally) dont?
