Thanks for the response Mr. Foxen. I was given an Xmax figure (via email) of 10mm by Etone believe it or not. (Sorry, I neglected to add that to the table!) I will contact them again and see if they have frequency response chart. Greg [quote name='Mr. Foxen' post='1216253' date='May 1 2011, 12:54 AM']There is no Xmax figure there, that is the one that tells you how much power the speakers will take before fartijng out. I suspect it may not be high for these speakers, you want to aim for around 4-6mm. Really need a full set of Thiele-Small parameters for good modelling, as well as a frequency response chart (because modelling doesn't tell you much around the midrange. WinISD Alpha is the recommended program, and the things you need to look for are excursion limited power handling, but I think the default is often the response curve, that will tell you if you cab will sound funny with one watt, but the power handling one will tell you why it is farting out.[/quote]

. Hi guys, I get so frustrated with speaker box design software! I just can't seem to get my head around them properly. I've tried Unibox408 and Boxplot2, online calculators, and get completely different vented box volume figures from each! Based on software reputation, I selected my Unibox figures as gospel and thought I had it nailed, building three 2x10 cabs fitted with [b]new[/b] Etone 1020 speakers. The cabs are to be honest, volume-wise, pathetic. The drivers distort at any volume. I've tried one, two and three of them. Direct out of the amp, linked, everything. The drivers are wired in parallel and the boxes have the recommended ports, sound deadening inside, etc. etc. [attachment=78733:3_x_twin..._box_rig.jpg] The tone is there at lower volumes, but as soon as I try to crank my Peavey MkIII 400 head's volume up above half they distort to buggery! This is regardless of pre and post gain adjustments. I even tried a mate's (other) Peavey bass head and the speakers were still the same. I'm half bald and if I had hair I reckon I'd be tearing it out at the moment! Can anyone who is familiar with speaker design software PULEEEEZE run these figures and see what [b]you[/b] come up with? (I ended up with 65 litres for a twin driver box.) I'm over this! [attachment=78734:etone_1020_specs.jpg] [size=3]Any help/advice is greatly appreciated![/size] Greg

. Hi guys, newbie here. I'm interested in the Orange BT1000H. Unfortunately I don't think they have made there way here (Orstralia) yet, so i can't check one out for myself. Has anyone here in the forum got/tried one? What do you think? I've read of the BT500H getting muddy/distorted at high volumes and losing some of its tonal qualities. Is this still the case with the 1000? Any thoughts greatly appreciated. Greg
