Yes, there's a 10 band EQ on my "new" combo I'll be playing with! (See pic in first post.)

Right, I get you now. Yes, you're absolutely right. All my speakers are full range. They do, however, have differing frequency responses and resonant peaks. The 4x10 defo sounds brighter. I'll be taking advantage of this. Also, there's inertia. A 10" speaker finds it easier to vibrate at high frequencies than a 15". The 15 can do it, just not quite as well as the 10. So, it's a case of any little thing I can do to minimize mud. And it'll be fun to try! I hope my explanation above of what I'm trying to achieve clarifies my intent.

I know. It's dual amping. The separate power amps are after the x-over, which IS bi-amping. Bill, with genuine respect, your replies aren't making a lot of sense to me . Maybe I'm missing something, but... "Don't bi-amp when both speakers are operating in the same frequency range. ......" Then why does the concept of bi-amping even exist? "Where bi-amping would make sense is using a 110 with a 215, and then only if the 110 is loaded with a guitar driver." I really don't get this. I'm sure the 4x10 cabs made byTrace Elliot, Hartke et al aren't loaded with guitar drivers (I'm not saying you can't use them, you'd just get a different frequency response). Let me be clear on what I'm trying to achieve. I'm looking for as much clarity as I can get. I do a lot of chord work, which can get muddy at times. I know that using a x-over will not only separate high notes and low notes, but will also separate upper harmonics from low notes, which I'm hoping will cut down on intermodulation distortion and clean things up a bit. I've even considered a third frequency band and getting some HF horns. Telling me "Don't bi-amp" is pointless. Why does anyone do it? Why do (did) amp manufacturers make preamps with x-overs built in? There has to be a point to all of that. I have to find out for myself. All I wanted to know was a recommended x-over frequency, and if I could use a line level PA X-over (available used and cheap).

That's what I'm planning to do. I think our posts crossed, see above.

I plan on using either the preamp on the GP11 (out through the "send", or my old Behringer V-Amp Pro, through the x-over then highs back to the GP11 "return" and 4x10, and lows to the HH power amp & 2x15. So yes, I'll be using the x-over at line level. I've had great results with the V-Amp & HH rig. Midi switching is amazing!

Hi All! I'm Pete, 63, from Essex UK. Been playing guitar since I was 12 (so over 50 years - whew!) and started Bass about 20 years ago, filling in for a friends band then staying on as I'd fallen in love with bass! I've been singing for as long as I can remember. I play Classic/Heavy Rock covers in and around Essex, alternating between Bass, Baritone, Guitar and extended range 7 & 8 strings. Growing old disgracefully!

Hello all! I've just acquired a Trace Elliot GP11 4x10 combo,and I'm thinking of combining it with my ancient HH rig ("Bass Baby" 150W head & 2x15 cab) to make a bi-amped rig. So my questions are:- 1. I need a crossover. Will any of those 2 way stereo/3 way mono 24dB/Oct rack units that are all over Ebay be any good, or if not, can anyone recommend anything? (I know I'll be going unbalanced/balanced/unbalanced, not a problem.) 2. What crossover frequency would you recommend? I read an article many years ago and I think they said 250Hz but it was loooong ago and I can't remember. While I'm here, does anyone know what the wattage is on my combo? I think it's 150W but strangely can't find any specs on the web. Thanks! Pete.
