Re: ZX Spectrum Build

After finishing up the cosmetics of the speaker and putting them back together I noticed I was back at the 'No Bass' category. I rebuilt the crossovers with air core inductors, I took them apart and changed polarity each way possible, made sure everything was sealed and beat my head against a wall s...

Re: ZX Spectrum Build

I've got to say, these things sound awesome. After sealing the tweeters in greatly and giving the woofers some time to break in I was getting some really deep bass and great highs, but the beater on a kick, snare hit and gain guitar lines were very thin. Tonight I swapped the phase on the tweeters o...

Re: ZX Spectrum Build

While working on these I sat on the floor (they're in a very tiny room currently) and was amazed that the bass response is much greater with my head at driver level or below. So I believe that most of my issues are probably in room layout and speaker location. I plan on raising them up a bit when th...

Re: ZX Spectrum Build

Thanks for the recommendations. I know how annoying it can be trying to debug someone's issues remotely, especially when they don't have a great amount of knowledge in the area. The resistor going to the tweeter is 8.2 Ohm instead of the specified 8 Ohm, but I doubt that would have much effect on th...

Re: ZX Spectrum Build

After work I pulled all the cables through the cabinet and verified where everything should go. I returned the tweeters to how they should be in the schematic and reassembled everything with no real improvement. Having the tweeters in the correct configuration does make the highs sound better and im...

Re: ZX Spectrum Build

I swapped the polarity of the tweeters, so positive to positive, ground to ground and it helped greatly. The tinniness is gone and bass instruments actually sound more like the actual instrument. The low end still seem to be lacking punch, but maybe I've just become too use to the monster pioneers w...

Re: ZX Spectrum Build

I set up the speakers on the Lepai amp with a similar result. The port is the 2" port with the 3.5" tube from the Meniscus kit. I set up a few of the other speakers I have at the house http://imgur.com/a/plAJ0 and would say that the ZX has weaker bass than any of the 3. The large 4 way Pioneers are ...

Re: ZX Spectrum Build

I've tested with a lepai 2020 with the same initial result, I'll verify again tonight as that was before I had added much padding. There doesn't seem to be any air leaks besides the port, which isn't sealed in yet. The box is constructed with overlapping rabbets and the back, sides, top and bottom w...

ZX Spectrum Build

I'm currently working through my ZX Spectrum build. I have the boxes built and am sketching out how I want to finish them. I ordered the kit from Meniscus but opted for Paul Carmody's 30 liter box design as opposed to the design from the instructions. A link to the gallery http://imgur.com/a/f1jIF I...
