Need Inexpensive Crossover
I'm using Monitor Audio GR-10 bookselves and a Klipsch powered subwoofer. Right now I'm running them both full range - and using the low pass on the crossover to have it kick in at about 80hz.
What I want to do is to roll off the low end on the bookshelves - as the bass sounds a bit too muddy at higher volumes (and just send the higher frequencies to the bookshelves - say above 80hz)...... and then just send the low frequencies (that aren't being sent to the bookshelves) to the sub (and probably not use the subs lowpass filter at all).
I know that crossovers can get to be pretty pricey, as all high end audio can. However, right now I'm a bit tapped out on the high end audio budget... and need something that will do for the moment - maybe I can upgrade lower.
Do I need something that has both a lowpass (for the sub) filter and a highpass (for the bookshelves) filter. Can one crossover unit combine this, or do I need 2?
I'm looking at spending no more than $100.
Is this possible?
thanks for the help (in advance)

Go to www.partsexpress.com. Item # 266-272. This is a passive low level high pass filter, 12 dB/octive 70 Hz. Including shipping it will cost you about $60 for two. A better solution would be to spend more than $100, and get a real crossover. I suggest Marchand Electronics. They make several models, and if you can build a kit they are inexpensive. |
Consider the Behringer DCX2496 (XLR in/outs, but RCA/XLR adapters are easily had). Active crossover and digital EQ functions. Under $400 new. I have found it transparent in a $15K system. It's EQ function has tamed a huge (+15dB w/Rat Shack analog sound meter) 50Hz room node at my listening position. Given that competing products cost 10x or so more, it's a steal. In many cases allowing your monitors to roll off naturally at the low end when augmenting the bottom octave with sub(s) will give better results, particularly midbass imaging and especially at low/moderate volumes. The Rat Shack sound meter (admittedly imperfect)plus your ears will allow you to use the Behringer to blend your sub in a more controlled fashion, possibly allowing a sub low pass cutoff well below the 80Hz, where the sub will actually be handling things like the bass notes of male vocals (yech). |
Eldartford Yep, I took a look myself a while back. Even a better rebate going on that one! Behringer looks like they are alone at their price points in the market...I agree with you, I don't know how they can offer so much for so little. P.S. Was just pulling your leg above regarding all the extra reading. Dave |
The Behringer 2496 is indeed a lovely way of making x-over dabbling a bit less tedious... with its full array of filter slopes and q. I had considered getting it to use as a tool in designing xovers for my spkr projects (including line level filters and passives). But the price, while excellent, was/is prohibitive for me :( |
There is also Outlaw Audio's ICBM. While primarily designed for bass management for multi-channel audio (SACD, DVD-A), it can also be used as a 2-channel crossover. It has continuously-variable crossovers from 40HZ-up, and either maintains stereo bass output or combines low-level signals into a mono LFE-out. New it is only $249, and I think there are some used ones listed on A'gon for under $200. |
Sogood51...I did study the material on 1st order series X/O which Karls provided. (If you are there Karls, thanks again). Once you wade through all the greek alphabet it really doesn't say anything profound (IMHO of course). Next thing I predict is a parallel/series three way crossover. Be the first on your block to own one:-) |
Those paradigm x30 are handy and sound pretty good. At a point I had 2 of them. When they say mini they arent kidding. If you can find these used grab one, used in the neighborhood of $100 or less https://www.minidsp.com/products/minidsp-in-a-box/minidsp-2x4 |
