custom Crossover building service??

Theaudiotweak...I think that in some cases changing the design of the crossover, (break frequencies, slopes) can yield better performance, but you need to know what you are doing, and be prepared to tweek in your new design. The original designer probably didn't get what he really wanted. He did the best he could within a budget.

It happens that I am even now in the midst of replacing the very simple crossover in MG1.6. In addition to using top quality inductor and capacitor I have chosen to change the filter break frequencies very slightly. In a nutshell, I will roll the LF panel off (electrically) at 205 Hz instead of 180Hz, and shift the HF pannel up by 100 Hz. My reasoning is that the speakers were surely designed for full range use, whereas I cross them over to a subwoofer system. Accordingly, I feel that the LF panel can handle slightly higher sounds without problem. Giving my theory a try makes the whole exercise more interesting, and it would be really easy to go back to the original L and C values if appropriate.

I did not to want screw up the time arrival balance of the 5 drivers in my Dunlavy SC4's. I elected to change the mechanical and material makeup of the crossover only, all the values remained the same even as the crossover grew out of the enclosure and into its own separate chassis. The crossover components, chassis, and all ten, 10 ga. Sonoran cables wired directly to each driver weigh in at over 65 lbs each. The chassis is of 2024 aircraft aluminium, and of course direct coupled using Audiopoints.All interior walls of the Dunlavy speaker cabinet have been coated with Cascade VBloc, a water soluble product that is drawn into and seals the wood. All hardware was replaced with brass..nonferrous fasteners. The speaker cabinet resides on a Sistrum SP101 platform and leveled left to right as well as verticaly to achieve proper wavelaunch and arrival at the listening position. Tom

I neglected to also give AuriCaps my recommendation in terms of capacitors.

Thanks again guys. What about using a 2-way adjustable electronic crossover instead? I already have the amps to do it.

the speaker is a 2-way & has 2 8-inch drivers and a tweeter.
I'd run the crossovers high pass section to an amp then straight to the tweeter. run the low pass section to an amp then to the woofers. Would I hook both woofers up the same binding posts or run the wire to 1 woofer then branch off to the next? Right now both woofers are hooked up to the same leads on the speaker's passive Xover boards. the amps an crossover both have gain controls.

Draggcj...Connecting a tweeter up directly to a power amp is risky. Turnon and turnoff transients, and other disturbances with LF content can easily toast a tweeter.

The mid/tweeter crossover (typically in the range 1500-2500 Hz) is best done using a passive circuit. The necessary inductor and capacitor values are reasonably cheap, even for good quality parts. Electronic crossovers are superior for lower frequencies, and almost essential for a subwoofer.
