Hello.

Wow ... this is probably gonna come across as a real dumb-ass question, but as I have never made my own cabs before, I am just trying to clarify a few things.

I use Cerwin Vega SL36 and PS215B subs and am looking to make some 'upper bass' type cabs to sit between my subs and my mid/highs and as a complete newbie to 'cab-making' I am ALREADY stumped on a few things!!

Firstly, is the HD-15 supposed to sit as depicted in the plans view (ie. with the horn/open side on top) or should it sit the other way around with the horn opening at the bottom (I would assume that they normally sit with the opening at the bottom)??

Secondly, and please excuse me if this is answered in the guide link, but whereabouts do I fit the connector plate??

Lastly, for all you guys that have actually used these cabs (albeit with various drivers), I want to make 4 of them loaded with Peavey Black Widow drivers (purely because of my location, where availability and therefore service/support/repair of other decent drivers is more limited ... I run a small sound hire facility in a small Town which unfortunately does not warrant having spares in my inventory etc) and I would like to know if I will be heading up the right pathway if I am trying to get a more solid (ie. tighter) kick to my system which comprises 4 x SL36's and 4 x Peavey Impulse 1015's in my larger rig and 2 x Cerwin Vega PS215B's and 4 x Peavey Impulse 200's in my smaller rig.

What I mean by 'more kick' is that my Cerwin Vega's contribute MORE THAN ENOUGH to the foundation shaking (weight) sector of the lower octaves!!, but they are more suited to the BOOM of dance music and they don't really perform above 90 - 120hz.

I am therefore trying to take the 'body' of a live miked kick drum away from the Impulses which do not really like to take over at 90hz - 120hz (which is where I cross them over from the Vega's) and I am assuming that a pair of nice 15" bass cabs operating between say 100 - 200hz will fill out the punch factor that I feel is missing between the subs and the Impulses.

Thanks for any answers and assistance.

Regards

Steven (South Africa)

Hey Steven. The peavey driver you mention is not really suited in the application you are looking at (90Hz+) in the HD15 compared to other drivers. Where are you located in SA?

P.Audio is distributed in Jhb, Dbn and Ct, and the C15-500LF comes recommended by some users. There are also a couple of other options, but in sunny SA the options are limited (and more often than not completely over-priced)

You may want to check the Peavey "Pro-Rider" out.  Same price, better specs.

Hey.

I am in East London and my initial reason for sticking with Peavey is the availability of basket assemblies and basically ALL transducer components etc, so I definately will be looking into the Pro-Rider range.

I was absolutely APPALLED to find out, when a bass guitarist put his guitar down and the jack shorted onto something resulting in a terrible high frequency screech which fried the tops in my old (and immediately thereafter GOTTEN RID OF!!) Cerwin Vega 152's, that I could not get a replacement driver or diaphram without sending the old one down to agents in Cape Town for a swap out.

I mean, for someone with enough capital to carry spare drivers etc that may not be a problem, but for someone like myself going DEEP into the pockets for the Cerwin Vegas, I thought that was pretty CRAP!!

P.Audio ... ??  Any specs, or a URL for me??  Efficient?? 

Hey ... here is another thing for you, Timber_MG ... can you, or do you know of anyone who would be willing to build me 4 of these HD-15's without finishes (ie. just timber work).

Thanks guys.

Steven

Hi Steven. It is a matter of using the right driver for the right application. Check your private message and email me. I'll send you some more info (one cannot attach images to PMs) and we could share some costs if I have a larger run of a cab done to save costs.

Regards

Martin
