No I don't have an spl meter. I've been looking at a few spl meters available online locally and they all have frequency ranges from 31.5hz - 8khz are these some magic numbers ?. Why don't they go up to 20khz ? Would they most likely measure sound outside those parameters but need a correction...

I'd sooner make a new box. Today I plugged the ports with the foam and gave it a test run. I'm quite sure the frequency response is better than it was. I've reconnected my ep2500 and giving it much more power now. I'm very confused about what I'm supposed to hear between 20-25hz. I get lots of...

Here's the foam I was talking about. Almost resembles the same density that HSU uses with their subs

I haven't tried this but I'm interested to see what happens, I have very dense packing foam at work that I could cut to shape and try. Robert, could you suggest modifications to my enclosure to achieve 25hz tuning ?

Here are the dimensions of my enclosure. The MDF is actually 20mm thick, not 15mm. Can you approximate what the enclosure is tuned to given these dimensions ?

You raise some interesting points Robert. I suppose it is only a graphic EQ after all. I will consider a parametic EQ when funding allows. At present my ep2500 is sitting in my cabinet disconnected because running the sub off this little amplifier seems to be doing the job. I'm confused as to...

No problem type A. I'm considering purchasing a decibel meter to graph frequency response. What I'd like to see is how these two amplifiers compare when driving my 18" sub. For the ep2500, the Sansui will be used as a pre-amp so EQ settings will remain the same.

Thanks Robert and schan for your input. Wow had an interesting day today testing out my setup. I have many topics to cover. First off, I had a different amp to try my sub with. Now this is funny, my dad was kind enough to loan me his old Sansui class A amplifier from 1978! Its only 100w per...

Ok the Sub is in my living room now. But does anyone know how to set the low pass filter on these sony a/v receivers ? The model is an strdn1020. I can hear the lower octaves of peoples voices when I'm watching movies. Will I need to install a crossover between the sony receiver and my behringer...

Found this online, a bit more info

ok if I can save space and go deeper at the same time.. then sealed it is :) oh and robertj has helped me in the past.. hope he can chime in at some stage edit.. Are sealed enclosures usually smaller than ported ? Reading the manual of this sub tells me the opposite is true

Interesting schan1269 but a Trans Line is to tall / crazy for what I was thinking hehe. I'd prefer a more conventional design. I know to satisfy the lower frequencies a ported enclosure is usually recommended. But if it means the enclosure is a little smaller than I can always go for sealed as...

After much hesistation back and forth, I've finally gone ahead and purchased a 2nd hand Behringer ep 2500 to run an 18" sub. I live in New Zealand and my original plan was to buy a stereo integrity 18" sub and import it with their resonable shipping costs. But just this morning I came accross a...

Ok the only BIC PL-200 I can see on ebay does not ship international. However... I have now expanded my budget to include the HSU VTF-2 MK4. I see their amps are 230v compatible and they informed me by email they can ship to New Zealand. So now I'm just waiting on a shipping quote.

Correction I can see the BIC PL-200 on ebay and have contacted the seller to see if I can get international shipping. So lets throw that sub into the mix as well for now.
