Hi Everyone,
First post in a very long time.
I want to put forward a design that I would like to build.
Drivers I have selected based on there reviews and specifications are:
1x (per side) Scan Speak D3004-660000 Illuminator 1" Tweeter (4 ohm Nom
1x (per side) Scan Speak 15W4434G00 Discovery 5¼" Midwoofer (4 ohm Nom)
I will be using Passive crossovers at first for the 2 way with each side driven off Channel A of a NAD C245BEE 4 channel amp and the other two channels for the sub/woofer section separate below - so a passive/active mix.
I will be building a 2x8 Mini DSP as my preamp most likely at the same time.
The design will be Open Baffle but in a small form factor so will sit atopon a custom open baffle woofer system utilising 2x 12inch Jaycar CW2125 Paper cone woofers (Paralleled 2x8ohm = 4ohm running one channel)
The baffle for the 2 way will be non-tapered/ and will have standard rectangle shape with rounded edges both front and back with the woofer back edge chamfered. The tweeter will be slightly off center towards the center of the stereo image ( closer to left hand side of righthand speaker) to account for diffraction - not sure if this is advisable. The tweeter and woofer will be flush mounted to avoid more FR nasties.
The baffle will be approx. 200mm wide and 290mm high.
My design is inspired by Zaph's ZRT slightly and others I have seen but I don't want to spend to much on the woofer that Zaph uses (revelator) , maybe this is not a good idea to use a cheaper woofer which such a nice tweeter.
I currently use arta to do measurements using a inline XLR sound card, Behringer phantom power supply and onboard audio (acer laptop) for the out to the amp with no ability to calibrate the effects the soundcard (both) affect measurements. I have never used Speaker Work shop but am willing to learn it or maybe even purchase Sound Easy and build the associated jigs.
I have an ECM8000 mic that is not calibrated but I am using the generic cal from HT Shack to somewhat give a more precise measurement.
I also have no way of correctly measuring drivers for example in IB/large surface area but I could build one.
I know this sounds a bit all over the place but if anyone could give me guidance on system design and configuration it would be great :) especially regarding the driver suitability for each other and for open baffle midbass/midrange.
