I'm equally impressed by the sik by nine install near the seat belt in the background........

I know you like the Fostex but.......Have you looked into the Peerless 3" fullranges? Don't seem to quite have the clean upper range of the Fostex (which seems to play amazingly high quite well by the graphs at least!) but look easier to mount with a small magnet structure and graphs look like they play nice and low to match the mids. With creative install and tuning they could work? Jono PS. Cheap! Peerless 3" Link

Depends on where you look ^^^ Mach5 Mli6.5 Mids $36.00 each Jono

Small update New "tester" box has been built and tried to an extent. 0.9cube after displacements tuned to 30hz or 41(approx)hz when the port bridge is removed. 90mm PVC port with only very slight flares (need to get a bigger bowl to bend them over!!). Only time for a few runs but results... TL on passenger side windscreen and car sealed up. 131.7 @38hz with the 30hz port facing up, sub up. Tones 132.0 @44hz with the 41hz port facing side, sub up. Tones 131.9 @??hz with the 41hz port facing side, sub up. Music So overall the box has limited flaring, not finished very well, ports need to be smoothed internally at the joins, 16mm mdf (last box was 18/19mm) etc......... Not unhappy but could've been louder on the TL. Moves a shedload of air though............ That and sounds SWEET on music LOL gotta love this sub. Need to try it with sub back, port side/back as that yielded the best results in the last box. But unfortunately ran out of time....... Jono

I almost hesitate in asking this....... as I realise that this is not really what Mach5 seems to be about (and to be honest neither am I). But....... Has anyone here utilised the smaller IXL series (such as the IXL 10) in a SPL type situation? Competitively? I am currently competing in a series of Sound Quality events which have an attached SPL component (for an overall Champ). Not designed to be top end SPL type comp but something fun for the SQ guys to compete in. Anyway I'm simply after any hints that might be floating around, I know its very install/box dependent (basically I'm in a small hatch so loading is good!) but....... you get the idea. Has anyone actually pulled any numbers with them? Thus far scores have been fun but I have no idea if they are genuinely good though? Box is 0.7cube ported tuned to 31hz with 129.9 on 450wrms and 134.0 on 900wrms. (Made the mistake of clowning a genuine SPL competitor who was very chuffed with his 2x1500wrms "US Audio Bonecrusher" strapped amps and a single 10" HCCA Orion sub....................) He wasn't happy to lose by 0.5dB. Anyway........ Do you see room for improvement or should I accept it as it is and not ruin the good run? I've been getting 8/9 out of 10 for subbass in SQ with the judges VERY impressed which is pleasing, so I'm not keen to ruin that either. There is probably 2 or more combined events over the year. Thanks, I hope you don't take offense! Jono P.S. Just found out after 2 events I'm running equal first in SQ and first in SPL for my class. Against 3 way front active Scanspeak/Vifa/Rainbow setups.... Nice.....

As I guess your not running the front stage "active" there isn't really a need for the 9887's extra tuning features....... Lower model unit should work fine. Jono

Very nice, I'm liking the port insert alot......

Browser tells me that the picture is only 1x1 pixel....... Thats pretty small......

If I'm reading this right your cap is working as a distribution block to split the power from battery to the amps and the RCA's are passing the signal through 500 to the 1000...... My question is are you running two subs one off the 500 and one off the 1000? or 500 for front stage and 1000 for subs etc?? Jono

Cheap??? Cheap!!!! Amazon PG RSD Sale 10" $45 12" 49.95.......... Not that I've ever used/heard them. Or IA 187 maybe? Jono

Yes but if you contact Mach 5 they should be able to GET baskets, doesn't mean they sell them through the site.........

Doesn't ROE have a bucketload of them to download in MP3 format? Download, burn, then done!

You are best to build the perfect box for the sub to get the best sound out of it, rather than trying to get a sub to fit a specific box............

General rule as far as I know..... Higher = better, because.... Less Heat, Less Current, Lower THD (but this may not apply on a sub amp etc...) BUT......... obviously power output is compromised by this (usually lower except in some cases such as JL Slash etc......) So as stated above depends on the amp, depends on the car and depends setup. Jono

Holey Chit Mark.......................

Not to be rude but this has what to do with the question at hand? I'm biased but I think the IXL is a great little sub, especially for the price. Jono

They've been hitting a few forums that I frequent for about a week now..... annoying

Sealed, but it was in like 3cubic ft or something HUGE for a single 12. Wasn't a demo car just happens that it has a DLS 3way front stage and sub, powered by old school RF amps that had been modded. Jono

Nice, I heard one of these in a beautiful DLS equipped car 2 weeks ago. Sounded VERY good, output was the thing that surprised me. You'll have fun with that one. Jono

Thanks for the ideas and pic Adrian, looks like I'll be building a couple of boxes me thinks!! I'm also wary of loosing any hidden SQ's (LOL) as that is the main competition I'm competing in and the sub is working well with my front stage presently tuned low. Looks like I know what I'm doing over the weekend, building boxes! The only reason for me thinking 50hz might be too high is because the car seems to like 46hz in the current box. But also bare in mind the comp only allows music no tones....... so probably take that with a grain of salt as that was a number plucked from TermLab after a run. *And I don't have access to one besides at the comps* Jono

After doing a quick play with box building programs the 2 port plug looks to be out....... When unplugged the 2nd port would remove a shed load of space from the nett box volume and mean tuning would be similar to 31hz (0.85cube) using 1 port and 5Xhz (0.7 approx cubes) with both open. That tuning is too high even for single SPL use IMO! Currently its looking like the box needs to be a very rough 1.4cube GROSS internal using a single port with "bridge" to get 31hz (bridged) and 43hz (unbridged). Also this design means that the nett volume of the box remains constant. I'll keep playing with the programs and see what I can come up with. Thanks for the advice, should be interesting to see how it goes. Jono

Thanks all, new box is in the works now...... Moving to a single 4" port now as I have multiple smaller currently. I'm also thinking I will try to keep the sub *up*, SQ port *up* and the SPL port *back* to try and get some loading off the hatch (although this may only have a clearance of 8" from the hatch...... We'll see. Mark, Oowww 136......... nice I know there is more to go then! hopefully on the lesser power i have. I wouldn't call it domination but doing quite nicely against some good installs its just a pity that my highs (Tweeters) are letting me down SQ score wise! The mids are doing well even in a very off axis location. Jono

I think I know where you going with this...... And the setup can change to an extent. As long as there is time I can change location of the box, change port tuning (interchangable ports) or change sealed to ported etc...... But the sub itself must stay in the same "box" At the moment I'm thinking of having a PVC port that has an external "bridge"....... When the bridge is in tuning is to 31hz, when removed the tuning is to 43hz (approx)..... Hard to describe but this would mean there are two actual "ports" running through the box just that one will not be in use (open each end to outside the box) when the bridge (a U shaped PVC piece) is not in place. Do you think this is a workable solution? Jono

Are you sure they are wired in phase..... i.e. is the polarity of each of then correct?

Try www.mach5audio.com amazingly it has heaps of specs on this sub......... 1000wrms Jono
