impedance

Here is a stupid question, I have a DB751 that I use with a 4 ohm DB410 cab. I looking at stacking another DB410 on top and have the opportunity to get one semi locally for pretty reasonable, however it is 8 ohms. Running the two would do 2.66 ohms. I know the amp can do 2 ohms. Not sure if...

Hi, I don't know that much about impedances and I need your help. Currently I have an Eden WT550 that can go down to 2 ohms. I have two Avatar 1 12" cabs 4 ohms each together they are 2 ohms. I understand that much. But I'm thinking about getting a Mark Bass LM II amp which has 500W into 4...

There are several threads on whether to use the Boss FV-50L or FV-50H volume pedal after a bass. All have been answered with the assumption that bass & guitar are passive, high-impedance devices; "so use FV-50H". But after an active instrument (with onboard pre), is it still advisable to use...

Hi smart guys, I have a question about a 2 way cab. I've got the cap and coil for a 4K 2nd order high pass. The woofer load is 8 ohm. I was shopping 4 ohm mids to pair up in series. The impedance curve shows one 8 ohm mid driver providing a 16 ohms and up impedance at and above the HP...

Embarrassed to say I never understand how to match cab with amp: Looking to match a cabinet to my mesa boogie titan big block v12 specs: 1200 Watts @ 4 Ohms (840 Watts @ 2 Ohms, 650 Watts @ 8 Ohms), Simul-State™ Power w/ 4 or 2 Ohm Impedance Select Switch for optimum Power/Load Performance /...

I have K&K Bass Max pickup installed on my bass. I will play on street with other musicians. We have battery powered PA system. On one of channels it has jack input marked as "high impedance input". Manual states, that it has 500kOhm impedance. Will it be sufficient for piezo to operate or...

Going to be using a combo with a 16ohm speaker with an 8ohm cab. Naturally there is no 5.3 ohm setting. I remember seeing some tube amp experts saying that you actually are safer setting it for 8 ohm since tube amps don't like to have higher impedance load than the setting... Opposite of solid...

Soooo....If I plug into a rig with multiple input/gains (like a pedal board type of thing), is it the first input impedance my signal hits that makes a difference with a piezo, or is it cumulative? That make sense? I tried to do a search but not really sure if I'm even using the correct terms.

Quick question based on experiences: With my active basses this doesn't seem to matter and they sound pretty much the same across different amps, but my passive basses seem to be very picky @ the input impedance of amps. Sometimes they sound weak/whimpy on one amp and awesomely brutal on...

Recently picked up this amp head for fifty bucks, the pots needed cleaning something awful but now it's sounding good. It has high/low inputs, "bright" switch, single volume, 4 band knob eq and a "limiter" knob. Can't hear much difference with or without the bright switch, and not really sure...

Hi, I'm new to TalkBass and need clarification. I have an Orange 1000w Terror Bass head which can be switched to 4 or 8ohms, connecting to a GK 400w 8ohm cab and a GK 800w 8ohm cab in parallel. Do i need to switch the Orange to a 4ohm setting or keep at 8ohm? Secondly, given the above, have I...

Hi all, I'm working on a number of mods to a Fender Blender circuit for a friend of mine. A trick is that he's running at least two preamps in order to use a variety of non-western acoustic instruments - I'm reasonably certain that I'll be dealing with an instrument level signal, but the input...

Up until a few years ago I was using an Alembic F2-B preamp and I liked the sound (I know it's a fender stock stack) but always felt the output was lacking considering the rest of my chain (I like and sometimes do need volume). I swapped it for a Jule Monique and I immediately had way more...

I tried a search but couldn't find anything. I was wondering about 210 and 410 cabinets. They both are listed at 8ohms so if you have 2x 210s you end up at 4ohms but if you have one 410 you are at 8 ohms. Is this because they use different drivers or because they are wired differently? If they...

I have built a few home made cabs in my years, made a few mistakes along the way but I found this diagram and it is fool proof.. Explains Ohms per cab and breaks it down so you DON'T break down your rig by mis matching cabs and exceeding the Ohms limit set by your amp manufacturer.

Hey folks, I'm a little confused about this 2x15 cab I just picked up, and im hoping someone can help. It's rated 160w at 4 ohms, but at least one speaker has since been swapped out... One of the speakers is a 4 ohm 110w Pyle mh1540 and the other looks like an old sunn speaker, but it doesn't...

A question. Is matching the pickup impedance only important when a bass has a preamp? I have a passive bass. I want to change out the pickups and the electronics. The electronics are crappy hard to turn Chinese pots with no pot values printed on them. The replacement electronics:I don't know...

I've been looking and I can't find one. I found plenty for guitars but not for bass. I think it would be a great resource. a very simple spreadsheet with different eras of p, j, mm, and other common (or uncommon) pickups. their resistive values, pole types, coil info, color codes, dimensions...

Right now the first piece of gear I would like to use in my signal chain is my dbx 166xl compressor, but it takes line level low impedance signals while the bass signal itself is obviously high impedance. The three pieces of gear I am considering are the following: Live Wire Solutions SPDI...
