    Test speakers under my bench

    Maybe a dumb question. I want to move my 12” test speaker from my bench shelve to under my bench.
    Just wondering if any of you have this setup and if there are any drawbacks?

    I had a pair of 2x12 cabs under my bench the last 20 years. They were my main test speakers. They were out of the way and not taking up space I needed, I could hear them just fine. I brought the wires from them up to a small patch panel on my bench riser. My dummy load was under there as well, and I brought those wires up to the panel as well.

    In another shop I had an old West 4x12 cab - loaded with SROs of all things - sitting beside me at the bench. I used it as a table for my tool box.

    My test speaker lives under the workbench, it's a JBL 12. The drawback is, even though the JBL is a very bright speaker, I can't hear much clarity from it unless I pull it out from under the table. So . . . it sits on a wheeled dolly making that maneuver easier. I'd recommend putting a set of wheels on your test cab, or park it on a similar board-with-wheels-on-it. You'll need a direct path speaker to ear those times you need to evaluate hiss and low level noises.

    Another thing I keep around to help hear hiss & low level racket - a piezo horn driver mounted to a small plastic horn. With a speaker cable attached, quarter inch plug on the cable for easy attachment to most amps I work on. I keep it in my junk room generally, and break it out when needed. Must have cost about $30 to put together. It often answers the question "am I really hearing this, or am I imagining it?" The piezo is super responsive to high frequencies, and needs no crossover but you could put a 1 uF or so film cap in series with it if you please.

    The test speaker under my workbench/dining room table was a 12" Mojo speaker (mfg unknown) mounted in the open back cabinet for my 20W 1978 Peavey Studio Pro SS combo amp with the chassis removed and replaced with a block of styrofoam from a shipping carton that happened to fit with a little persuasion. Its purpose was for testing for problems - if I was doing fine tuning tweaks I'd connect the chassis (usually from a combo amp not a head) to its regular speaker.

    P.S. I took the liberty of correcting the spelling in the thread title as I am sure the OP would have done if he could. I normally do not edit posts unless requested by the member who posted it...

    Since I don't actually work at my bench all that much, and I don't typically play my own amp when I'm doing that I just keep my 1X12 combo under my work bench and use it for a test speaker. A place to keep my amp that's out of the way and a test speaker all rolled into one. It's a duotasker Like Leo said, it can hamper fidelity. But I usually do my refined listening checks through any amps own cabinet anyway. I have, on occasion, just scooched the amp out for listening too, but if you'll do that a lot then the wheels are a good call.
