Ar9Jim 6,512 Posted February 19, 2015 Posted February 19, 2015 The older post I have read so far have lead me to believe that home type crossovers are not common with RCA connectors.They seem to use balanced type connectors and I also read that the adaptors don't work so well.Dom was dealing with this issue in some old post.I would like to set up a bi-amp system but would like to avoid adaptors and have standard RCA connections.Any one know of any good stereo 2way crossovers with RCA connections?
B-Man 4,780 Posted February 19, 2015 Posted February 19, 2015 Elliot Sound Products If you go there, scroll down to the crossover section. There are several types available. These are kits however. You have to buy the parts and assemble them yourself. 2
Bean 384 Posted February 19, 2015 Posted February 19, 2015 MiniDSP 2 x 4 RCA....... Its a fully electronic crossover that you can use to split each L/R signal into 2 outputs, one for your highs, one for your lows... If you spend a bit more on the UMIK USB Mic, you can then incorporate REW (a free EQ graphing program) to get your room response and generate a correction curve... which can then in turn be loaded into your MiniDSP to provide a better EQ curve.. You could also use this to go fully active, meaning removing the crossover from your speakers entirely like Gary (TNRabbit) did in his thread "I'm Going Active" Pretty cool device... Couple posts around about it. I'm just using one to EQ my new sub since my existing receiver doesn't have EQ capable of flattening out my sub response. 3
TNRabbit 371 Posted February 19, 2015 Posted February 19, 2015 SOME of the Rane units have RCA connectors, too.... 1
zumbini 6,147 Posted February 19, 2015 Posted February 19, 2015 If you are adding a subwoofer to a full range speaker an Audio Control Richter Scale is a good choice. They come up on ebay pretty regularly for $80-150 (original model) and $160-250 (Series III). The original offers 2 XO frequencies (100Hz or 600Hz), a 1/2 octave EQ and warble tone generator. (You'll need the original condensor mike, or equivalent, to take advantage of the built-in analyzer.) The Series III can be adjusted for any XO frequency using readily available plugin resistor modules. The unit I bought in the 70's came with 80 and 120Hz chips and a postcard you could send in to get a 3rd chip free. Most of the units I see on ebay don't mention the 2nd module but often it's taped to the PCB inside. (Again you'll need the original condensor mike, or equivalent, to take advantage of the built-in analyzer.) This is a crossover module (it's just a simple resistor network on a 16 pin DIP), and instructions for changing the crossover frequency: 3
slbenz 110 Posted February 20, 2015 Posted February 20, 2015 I would second the MiniDSP. That is what I am currently using and sounds much better than the ART CX311 it replaced. Unfortunately, I experienced issues with the ART due to the adapters needed to convert all the inputs/outputs to unbalanced. I found that the adapters contributed to an intermittent stray signal that maxed out my left upper channel which in turn slightly damaged my Magnepan speaker. Luckily, I know how to repair the Magnepan and is working fine now. Having been using the MiniDSP for several weeks now, all I can say is that I should have done it this way first and not go with the pro crossovers that you can easily find. Not having all those adapters I am sure didn't help with the sound quality. The MiniDSP is very easy to program and can easily be tailored to your speaker's needs. I have the ART currently up for sale which is only a year old. That tells you how much I like the MiniDSP so far. 1
DaveStL 85 Posted February 20, 2015 Posted February 20, 2015 Pass Labs makes a nice one, sounds great, very flexible, and w/ both RCA and XLR. Originally intended as industrial gear, though, so expensive. Marchand XM44 is reported to be very good, but you buy them to spec--need to get the freqs and slopes figured out first (e.g. w/ something less expensive that's adjustable). You can get modules for them to change the XO, though. IIRC, the pro ones (which will be XLR) are 4th-order only, albeit w/ adjustable XO point. Depending on the speakers, you might want something less steep to get the drivers to blend. Seems like I just talked myself into the miniDSP (except I don't need another XO). 2
BillWojo 542 Posted February 21, 2015 Posted February 21, 2015 Can someone explain what 2nd, or 3rd or 4th order means? I think it has to do with the frequency but I haven't found a good explaination of it. Thanks BillWojo
RodH 4,866 Posted February 21, 2015 Posted February 21, 2015 Short answer is it's how 'aggressive' the frequency rolls off at the crossover frequency. The higher the order, the steeper the drop-off past the desired point. Take a look at this: http://www.rane.com/note160.html 3
Bean 384 Posted February 21, 2015 Posted February 21, 2015 Seems like I just talked myself into the miniDSP (except I don't need another XO). Just remove the XO from your speakers and go active
chiroacademy 833 Posted February 21, 2015 Posted February 21, 2015 Just ordered a miniDSP. Looking forward to checking it out
DaveStL 85 Posted February 21, 2015 Posted February 21, 2015 Just remove the XO from your speakers and go active Using the Pass now on Maggie 3a's, which are easy to biamp. That's why I don't need to buy another crossover. Sounds pretty good , wish I were home listening instead of sitting in a hotel room in Crawfordsville, IN waiting for 6" of snow--but that's another thread.

Dave, I agree with you, the Magnepan IIIas are very easy to biamp. Enjoying my IIIas with the MiniDSP. Sorry to hear where you are for business. I just came back from a three day business trip at Honolulu. Lot warmer there.
