Chris Horton Posted June 16, 2013 Share Posted June 16, 2013 hi everyone, I have placed a "wanted" advert for an Epifani , series 1, 8 ohm cab to go with my 210 or 410 cab. I appreciate that the Epi series 1 cabs don't come up for sale that often so it got me thinking ........ What other lightweight 115 or 215 cabs should I check out ? I use an Epifani UL502 amp and my main bass is an MTD 535. Throw me your thoughts please Cheers Chris Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted June 16, 2013 Share Posted June 16, 2013 Mixing cabs is a bad plan. The reason it is a bad plan is that the sound of the combination is totally unpredictable, so as soon as you plan on mixing the cab with unspecific different cabs, you can't get any useful suggestions, because nobody can know how they will pair up, the sound isn't a combination of the souds of the two, its another sound again. Do you like the sound of the 10s you have but need louder? Get more the same. If you don't like the sound of them, get rid and get somehting you do like the sound of, then add more the same until loud enough. Quote Link to comment Share on other sites More sharing options...

JTUK Posted June 16, 2013 Share Posted June 16, 2013 I've never seen any value in a 15" cab, so would add a Epi series 1 210 to your list...but if you already have a 410 as well, maybe that doesn't really get you anywhere..?? Quote Link to comment Share on other sites More sharing options...

Until roughly 1975 for the most part there was no such thing as guitar versus bass drivers, there were only musical instrument drivers, most of them designed for guitar. Some fifteens were designed for organ and PA, and worked better with bass than guitar tens and twelves. The original 1969 SVT was loaded with guitar tens, that's why they needed sixteen of them to handle the 300w head. Taken in that context, circa 1950-1975 there was some benefit to mixing cabs. That benefit went away with the introduction of true electric bass tens and twelves. Quote Link to comment Share on other sites More sharing options...

The 210 is a great cab for the size & weight but not quite as full sounding as the 410. I do run the 410 & 210 together for bigger gigs but when I do , it feels like the 210 cab is struggling compared to the 410 if that makes sence.

lefrash Posted June 16, 2013 Share Posted June 16, 2013 I've always been a 1x15 kinda guy. I'ver always thought no matter what rig I run I should run my wee 1x15 DI cab just get the 'bottom end'. Now tht I've got a right nice 2x10 with nice speakers I've realised that a 2x10 is sufficient! It just hits the perfect frequencies to cut through so that I'm never struggling to hear myself. Sometimes taking away will add to your sound. Quote Link to comment Share on other sites More sharing options...

Lozz196 Posted June 16, 2013 Share Posted June 16, 2013 Yes, if anything sounds like it`s struggling, best to not use it. My 410/210 set-ups worked fine, but I let the ears decide, any chance of bother, don`t do it. Quote Link to comment Share on other sites More sharing options...

I use the word "struggling" as i dont really know how best to describe it. I am not running any of my cabs at mega high levels at any time and they never destort........... its just that i can hear the differance between my two cabs. I probabbly use the term "struggle" in the wrong context maybe. Maybe 2x 410 cab's would balance things up more ?

Lozz196 Posted June 16, 2013 Share Posted June 16, 2013 Well the ideal is always two of the same cab if one isn`t enough. Aside from all the techie stuff, there`s the benefit of using one cab for rehearsals/smaller gigs, then when you add the second, no need to re-eq due to different sounds. You just get double your regular sound. Quote Link to comment Share on other sites More sharing options...

[/quote] Depends how low you can run the impedance of the amp...and if you can go to 2ohms, then I'd get another Epi 1 210... and then you are truly modular. Maybe the 112 and 210 are pretty simillar or arther cover the same gigs so you could sell the 112 and have 2x210 and/or 410 in the rig. The amp would have to do 2 ohms thnough...or for a killer big rig, slave the second cab with a power amp driven by your main amp. Quote Link to comment Share on other sites More sharing options...
Chris Horton Posted June 17, 2013 Author Share Posted June 17, 2013 I only use the 112 cab at home when practicing really and then I take the 210 for small gigs etc. I think my wife would kill me if I bought another amp Quote Link to comment Share on other sites More sharing options...
Phil Starr Posted June 18, 2013 Share Posted June 18, 2013 Just to redress the balance. It isn't true that mixing speakers is always a bad thing or that the effects are completely unpredictable. If this were so then everyone who ever mixed a 15 with a 4x10 would sound bad and that simply isn't true. What is true is that if you mix speakers of different types (not just sizes) then the results won't be the best of both speakers, Normally you will lose the character of both types a little but if the resonances in frequency response coincide you might get something new appearing. It is also true that 15's aren't automatically more bassy than 10's or that 10's have more top, though this happens more than the reverse. It depends upon the model. I'm not advising anyone to mix speakers and certainly the only way to really know if a combination works is to try it before buying but if a half truth becomes repeated often enough it becomes the received wisdom.

But you can't even get SPL charts for cabs, let alone phase charts, so even if you knew how to use them to predict the combined response the necessary tools just aren't available.

Ziphoblat Posted June 18, 2013 Share Posted June 18, 2013 And I think by the time you're busting out your scientific calculator and some phase charts you're probably at a point where can just design your own cab to do the trick for you.

Phil Starr Posted June 18, 2013 Share Posted June 18, 2013 Not sure if this is a question or if you are just disagreeing. No matter, you'll have noticed I said "not completely unpredictable" so i only have to make one sensible prediction. If both speakers are 10dB down at 40Hz the combination will be down at 40Hz. In fact if I have an octave averaged frequency response for both speakers then I could give you the octave averaged response of the combination. If I had a third octave response then with a bit less certainty i could give more detail. Of course if I have no data as Bill suggests I can't make any predictions even about a single driver. So yes, you can make sensible suggestions about how a combination might sound. In fact you could put the parameters of two drivers into winISD, model them separately and then sum the results to give a reasonable prediction of the low frequency response. Given enough data you could calculate quite a lot including phase effects should you so desire, though most phase effects apply even if you use identical drivers. There is no doubt that this wouldn't give a complete picture of the results of mixing drivers and it isn't something I can ever imagine doing but even at a non-technical level you could make a stab at predicting how two speakers might interact. My main point however is that because designers rarely take on this challenge that the results are doomed beforehand and that because of this anyone who mixes cabs is inherently foolish. Empirical results trump theory, this is the basis of all science. Quote Link to comment Share on other sites More sharing options...
Guest bassman7755 Posted June 18, 2013 Share Posted June 18, 2013 I think that the point is that since there is no longer any need to use different cabs to get "top" and "bottom" then, given the choice, you may as well use multiple identical cabs and get the numerous benefits which arise from this.

LawrenceH Posted June 19, 2013 Share Posted June 19, 2013 It's not ideal to mix speakers, but often when money's an issue it's about availability and working with what you already have. As such I think it's good to put a little perspective in there - the sky won't fall down if you do it! Mixing cabs is only unpredictable to a point, probably less than theory might predict given that most cabs, sealed units aside, will have fairly similar driver characteristics and reflex tunings. Don't forget that room modes and speaker placement effects will in many cases dwarf those of the cabs. If you stack 10" drivers, consider the effect of moving back and forth in front of them - chaging the incident angle will unavoidably cause changing midrange phase cancellations and reinforcements as the output from the two drivers combines at your ear. A single larger driver doesn't show this, but OTOH will have reduced mid/high dispersion in the perpendicular plane unless crossed over to a smaller unit. There's one major advantage to 15" drivers that's been lost in all this - assuming similar driver quality then they can perform in a similar range to three 10" drivers, but costing and weighing significantly less. It's all about choosing the best compromise for your situation. Quote Link to comment Share on other sites More sharing options...
