104db@1w/m Cabinets

I'm a serious hornplan enthusiast and am looking for all the reasons to justify not spending TOO much money on JBL products (not that I don't like them, they're very expensive). I decided to build the ES-18BPH (by Stipe) using the Paudio C18-650ELF since the woofer is available in South Africa.

According to Stipe a single bin will give 104db@1w/m. If I get 107 using two bins then around 130db is possible at peak level. This is a setup that will cost around US$660 (R4600.00) excluding a poweramp (US$530 for 700w/ch into 8ohms). Please anyone that knows othe plans for C18-650ELF,C15-500LF or the Fane Colossus 18-XB/ Fane sovereign 15-500 make a recommendation for me. Around 105db @1w/m is my target and I will feel comparable to lower level JBL bassbins. Good low frequency is what I'm looking at and I'm also accommodating to ported boxes. Void-1000 and PD1850 aren't easy to find in SA and expensive to import.

Hiya Paul, welcome to the Forum,

As good as the ES cabinet is it is not a sub cab and should be only considered suitable for down to 45hz. Is this OK or are you looking at a cab that goes lower?

Hi Tony, thanks for your response.

Much lower frequencies will be highly appreciated but still, I'm limited by drivers I've mentioned. If I can get much better results out of any of these drivers, especially Challenger C18-650ELF it will be great. I'm using the cabs for house Music. Your advice is highly appreciated.

Kind Regards

Paul

hello mate, get a list of what drivers you can get at a cheap/reasonable price, will help selecting a cabinet.

Are eminence drivers available to you?

I have not seen a frequency response curve for these cabinets but I see the quoted response is -3db at 54 Hz.
Bandpass horn cabinets have a poor low frequency response individually, and really don't work properly untill multiple cabinets are coupled together, to increase the size of the horn mouth.
I would think that the ES18BPH probably sounds very impressive in groups of 4 or more boxes, but I would be worried about the low end frequency response with a single pair.
A tapped horn design would give more bottom end response with a small number of cabinets. But the C18-650ELF driver is quite x-max limited at 5mm so not really optimal for a TH design.

Xoc1,

Your response is great thanks. I'm planning to build up to 4 cabs. I'm already impressed with the C18-650EL and already have 2 cabs but my designs are very simple and taken from undefined box volumes. Lots of my enquiries are intended to help me do a more professional job. I'm aware of X-max of 5mm but it's so far pleasing with results and I targets smaller hornplans like the size of ES18 or even smaller (700High x 635Depth x 570Width). If I take value for money into account, I end up going for the 2 X C18 as opposed to 1 X PD1850. C18-650EL costs R1700 (US$242) locally. Importing PD1850 or Void will cost more than 2 x R1700 but they aren't necessarily unaffordable. I will see the some time next year.

A frequency of down to 45 hetz is good advice- more lessons to my DJ's. This is around specified Fs of 42 for the challenger.

Cutta- I'm afraid of that dog.

Affordable speakers around are: P.Audio: C15-500LF, C18-650ELF, FANE COLOSSUS 18XB and various Hybrid speakers but Hybrid doesn't post T/S parameters but 18H600 is good. We have a PAudio dealer many of their products are available here. Except the Flagship (FL-18ELF) Series though.

Eminence Kappalite 3015, SD18, PD1850, Void1000, DAS 18LXN/18SX and any you may suggest will be second option for me since I'll have to import. Unless there's a big sale around. Import facility is no problem since I buy lots of stuff by paypal.

I have heard XB's in these, two cabs ON THEIR SIDES work very well for House Music. Seems to make the perception of throw a litlle less.

Kappalite's in tapped horns apparently work very well, This may be a really good cost effective solution. Judging from the Martinsson 15" tapped horns that I have just started using they would be a very good all purpose box.
They will even work well as single's, two per side would be very capable.

Sorry, I meant two stacks like this, ie 4 cabs

I would suggest that you might be better off looking at the Cubo 18 design.
There is some info on the C18650EL on the Cubo 18 thread.
This should give a decent bass response with a small number of cabinets.
Only problem with most of the tapped horn designs is their lack of high frequency extension, you need a 12" mid or bigger to meet their upper frequency limit (for the cubo 18" this is quoted as 110hz).
The ES18BPH bandpass horn design will give a higher frequency bandwidth, but is really suitable for larger rigs, think Turbosound & Funktion one!
