almost full range enclosure for guitar build advice E140/E110/2213
Hi, first post here but I have read many many screenfulls from this great forum.
I've been playing around with different speaker combos for my guitar performances. I make a very full range sound, with pitched down bass frequencies, and even vocals running through the system, all running through a 120W Laney valve (tube) PA from 1969 which makes a sound I'm very happy with.
I started out with E120s which I love (I still have four) but the bass just isn't there, so I reinforced with an E140 in a non-ideal 1x15. It's okay for now, but there's major efficiency mismatches, so I'm running the E140 on 8Ω and E120s in a pair on 16Ω to compensate for the efficiency mismatch.
It's okay but I'd like to design a proper cab for shows, followed up with a second for bigger shows or when i want to work in stereo, which i sometimes do. So I'm thinking, can I combine the E140 with an E110 with a crossover and forget about having HF drivers as it's not really important for the sound I make? Looking at the specs, these two would seem to work okay in combo. What do others think?
I note the JBL full ranges for keyboard etc (Cabaret series for example) usually twin an 18" with a 10" or a 15" with an 8". Also, I'm having trouble locating an E110. Would a more available 2123 do the job? it matches the E140 in efficiency (101db to 100db). In building my cabinet i'll need to box around the 10" driver within the cabinet, is that right?
Many thanks,Toby
Almost full range concept
Hi, and welcome to the forum.
The full range pro speaker cabinet is very popular now and many 2-way and 3-way configurations are on the market. These are particularly popular as bass guitar cabinets. Slap bass style produces some extended frequencies, higher and lower, so this configuration works. With an E-140 you can build a good one. However, bass cabinets/speakers tend to resist break up and are generally considered too clean for many guitarists playing electric/distortion. If you are playing acoustic electric, it might work. What do you want it to do?
Using a small mid 6", 8" or 10 inch will bring some good highs for the guitar, but will not will not necessarily give you the crystal clear vocals of a horn. If its not enough, that's where the 3-way comes in. But that may be too much for the guitar. You are potentially looking at trade-offs here. If the speaker is behind you, feedback could become an issue. You could check out a 2-way bass cabinet at your local music shop to see if this is what you really want.
For building: the mid driver should be in a separate box within the speaker. The exact size depends on the crossover point between the low and mid driver, but they are generally less than 1 cubic foot. Have you used WINISD? The cubic volume for the mid box must be subtracted from the overall box volume to give the correct volume for the low driver. High pass and low pass filters would be a good idea to keep things clean.

All you had to do was ask
Hi Parker Knoll , I have a New old Stock E110 in minty minty nick and a very old D130 (Alnico ) in almost minty nick. Send me a PM if you are interested and we can work something out.
I'm in Scotland :eek: so there may well be export duty.
