I play a 5-string bass guitar. I have several speakers I use and a couple of bass heads. For practice and playing in small venues, I usually use my GK MB200 bass head because it only weighs 2 lbs. I often pair it with my Carvin 2x10, but I decided I wanted to build something lighter. I do have quite a bit of experience building home speakers, home subs and car subs. However, my first attempt building an instrument speaker for my bass turned out badly. I had purchased an Eminence Legend BP102 10" driver because of great reviews by many. I built a 3 ft3 box and slot tuned it to 30 Hz. In computer simulation, it looked good; but in practice, it didn't turn out so great. I'm not knocking the woofer because I'm sure it's fine, but my lack of expertise in instrument speaker design was the problem. I had tuned it to 30 Hz so I could get the full sound from my B-string, but one 10" woofer just isn't capable of much fundamental low B at any volume. I was bottoming the woofer out at even fairly low volumes, so it was back to the drawing board for me. I did much more research and discovered/decided if I wanted to try to get those low fundamental notes, (and yes, I know MOST bassists are happy with the 2nd harmonic being the loudest!); I was going to need a larger woofer (if I was only going to use one), and I'd have to tune a little higher (which still seems odd to me!). I used the same box I had built for the 10" woofer...well part of it after I cut off part of the front to make it smaller. I ended up with a 2 ft3 box tuned to 42 Hz for my new Faital Pro 12-inch woofer. I chose this woofer from specs (which I know can be deceptive). I also chose it because it had the neodymium magnet, which would reduce my box weight even more. I broke in the woofer overnight with a 20-Hz sine wave test tone, as I do all my woofers), and I mounted it in the box. Before hooking it up to my system, I ran some measurements. Turns out the measured tuning frequency was 37 Hz. So I hooked it up and gave it a shot. My initial impression was I liked the way it sounded. It was very smooth and full-sounding in the low end, and the upper was surprisingly nice as well. All my other speakers have a horn/tweeter, so I thought I might miss that crispness from the upper harmonics; but I really didn't. A few days later, I used my new set-up in our church's multi-purpose building. I am extremely happy with my new speaker!!! It sounds clean and low and the fundamentals are all there. The woofer never strained as I pushed it to keep up with the band. We had a drummer (no mics) and two acoustic guitars (both playing through a small PA along with 2 vocals), and my new speaker along with my GK MB200 was a perfect match! I highly recommend this woofer for bass guitar!!! I've found the sound to be one of the best I've played through. If I didn't already have the Carvin 2x10, which I really like, too, I'd probably build a 2x12 using 2 of the Faital Pro woofers. In comparing the 2 cabs, the FP has thicker fundamentals and smoother upper bass - I suspect a flatter frequency response, but I haven't measured it. The Carvin is louder in the mid-lower notes, but kinda has a suck-out in the higher strings/notes. However, the horn does add some crispness to the upper harmonics that is missing in the FP. I considered adding a horn to the FP, but I really like the lightweight cabinet as it is. I wish I could post a pic of my cab. It's interesting and definitely stands out for more that it's good sound. I built it with 3/4" birch plywood. It has a slot on the bottom tuning it to 37 Hz. I have one handle on the top back (MCM part #555-13531). The wiring plate (MCM part #555-13252) contains one Speakon connector (MCM part #27-7710) and one 1/4" connector (MCM part # NYS229). I lined the inside walls with Acoustic Wadding material (MCM part #LS00385). I covered the box in...wait for it...DUCK TAPE! LOL I used lime green Duck tape on the face, top, back and bottom. I used black Gorilla tape on the sides. I haven't put a grill over the woofer yet (as I usually do on my speakers) because I like to see the cone movement. I'm looking for a grill that is more open than the standard ones I usually get from MCM. I want something strong, maybe a bar-type. I would appreciate any suggestions. Again, I highly recommend this woofer, and I highly recommend MCM Electronics! I've purchased from MCM for 30 years, and they've never let me down!!!
