    Help choosing 6.5

    Thanks for the replies. Just seeing them today. I guess my notifications aren’t working with the update. I ended up getting Pioneer TS M650Pro’s for $70 to my door. https://www.sonicelectronix.com/item_65567_Pioneer-TS-M650PRO.html they were in my budget and the specs and build looked good. Should be able to fill the mids from my 8’s to the Vifa tweets. Plan is to bandpass from 80-100 to 2500Hz. At this point I have everything but the R mid/tweet installed. Amazing how many runs to stores I’ve made in the last week when I realized I forgot ANOTHER small/not so small thing.

    So I just ordered 4 of these...

    Just tested my box in my buddies Ford Focus. My amps aren’t in yet. Ran the 4 8’s at 1 ohm off of his Skar amp (SK-M5001D) @500 watts. Holy hell these things are ridiculous for the price! He couldn’t believe he was listening to $18 speakers.

    Final design. Will build next week hopefully. Waiting on amps, mids, and a few parts to show up. 4 cubes at 36Hz

    HU DSP/EQ/X-over or Audio contorl EQX?

    Thanks, that's what I was thinking you'd guys would say. I'll throw it up on Ebay and a few car audio forums.

    Yeah it started working on my phone as soon as I posted that comment. Thanks though.

    I’m frozen by the tyranny of choice. My budget is up to $120/pair. I have the Vifa eBay ring radiator tweets already the mids/tweeters will be powered by a Pioneer GMD 8604 What should I get that’ll x-over well with my 4 - 8” subs and the Vifa tweets (I’ve read they should go no lower than 2500). Limited to 3” depth unless I get/build a spacer.

    So weird, now that I'm off wifi my phone won't connect this site. Still goes to the old site w/the "sorry upgrade in progress" message. Cleared history/cookies. IE through work is a mess still as well. I don't get it.
  8. I'm about to install my first system since 'Nam. I have a Pioneer MVH-S600BS installed. I have my old, circa 1993 Audio Control EQx series ii that is in perfect shape. Which should I use for EQ/X-over duties? System will be Pioneer GMD8604 and GMD9601. Sub - 4 8" Blaupunkts, Mid is TBD but some 6.5 maybe silver flute, and Vifa ebay tweeters. I'm pretty sure the Pioneer is the better choice as it is 25 yrs more modern but thought I'd ask anyways. It appears the current EQx is identical. The other thing is the amp doesn't have a SS filter so with the HU X-over I'm pretty sure I can set HPF and LPF for the sub channel.
  9. texting my friend now about some cool CNC braces.
  10. Thanks, the 45's were already happening, just didn't have time to do that last night. Taught myself how to use SketchUp and spent way too much time messing with it. Didn't even think about front to back dowels. Think that is necessary for these cheap 8's? Dowels are cheap and easy but I don't want to lose net cubes. I could probably have my buddy CNC some sweet front to back bracing w/cut outs. That's a fun program! My buddy is a commercial cabinet fabricator, he did the new Sacramento Kings Arena, and he's going to CNC the box with Dado's. Probably not necessary, but I was going to biscuit join it just because I've never done it before and I have access to the tools.

    Yeah at home now on Chrome and it looks great. Just checked Safari on the iPhone and its good there now too. Tapatalk is still down. That may be permanent though.
  12. Here are the T/S numbers. I played with it for a bit, but everything I put into WinISD looked peaky. But I know very little and you wouldn't want my design anyways. They seem to look best to me in 2 cubes a piece at 32Hz. In the manual the box is 1.25 cubes per sub.
  13. Here's what I came up with after playing around with it for several days. Tried aeroports but they require too much surface on the baffle and I don't want to fire the subs opposite of the port. 4 cubes at 36Hz gave what I felt looked like the best graph. Rear port air velocity is under 16 m/s Thanks for the replies so far. Any advice moving forward. Pioneer 9601 is ordered, working on my wiring order. Might start construction this week. <iframe src="https://3dwarehouse.sketchup.com/embed.html?mid=752376f8-6513-48bb-a0f9-408b049d1d41" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" width="580" height="326" allowfullscreen></iframe> https://3dwarehouse.sketchup.com/model/752376f8-6513-48bb-a0f9-408b049d1d41/Four-8-subwoofers-box-in-4-cubes-tuned-to-36-Hz

    For me the site is a terrible mess on IE (what I'm forced to use at work) and still doesn't work on Tapatalk. On Safari through my Iphone it still says that its in process of ugrading. Weird
