    2 amps or 1?

    Hello all, I'm looking for a decent external amp to power my B&W 804's. I was thinking about getting two Parasound 2125's and bridging one per channel, or just get one 2250. 250 watts or 400 watts but with less low impedance capability. What are your thoughts on this? My 804's minimum...

    B&W 800 series?

    Hi all, I'm going to pick up a new pair of speaks. Looking to spend somewhere up to 4k for stereo. I will be driving them with an older 200watt/channel parasound but may replace it with something nicer within a few months. I was looking at picking up the B&W 804's. Anyone hear them or...

    Tumult Surround repair?

    :angry: My cute new kitten decided to sharpen his claws on my tumult surround. So there is significant damange. Luckily not to the kitten, though I thought about it. The surround is still intact, in that it's air tight, as much as I could tell by pushing on the cone as well as very low...

    Computer speakers... for work?

    Hi! I'm looking for some cheap & relatively inexpensive computer speakers for work. I'll most likely be plugging my MP3 player into them (creative MuVo Tx FM), so no worries about sound card, etc. I was thinking that I'd like a 2 channel system better than a 2.1 just for simplicity. At...

    Nakamichi CD-4, and Denon DVD-2500

    Nakamichi CD 4 Cd player, good condition, no remote, box or papers. Looking to get $100 for it. Nice player. Also, broken Denon 2500 DVD player. Older bugger -bought in late 2000. Plays CD's well, recognizes some DVD's. Often this stupid DVD player won't recognize that it's a DVD unless...

    Cascading crossovers subwoofers etc.

    This was in part spurred by the recent thread about using a Paradigm X-30 in conjunction with the receiver's crossover etc.etc. Who here is really happy with JUST a 12dB/Octave crossover? A friend recently built a Tempest clone sub with the parts express 250 watt plate amp and the 12dB/oct...

    BFD Setup Question.....

    Hello all, My awesome girlfriend bought me a BFD for my birthday, and I'm thrilled to be setting it up. I've noticed that most people seem to eq with just the sub playing test tones when they set it up -why is that? I completely understand not wanting to get excessive boost or...

    PR questions and Tumult apps:

    Hey all, I absolutely had to get a Tumult when I looked at the specs. As you read this, I'm probably still excitedly coming up with new alignments. I have a couple questions. I'm not sure if I want to try to make a vented or a PR enclosure. If I do make a vented, it'll be with a slot port...

    JBL Subwoofer Amp Woes...

    Hello all, I'm writing on behalf of a friend who bought a JBL PSW-D112 a couple of years ago. The subwoofer has since stopped working. When turned on, it will function well for about 1/2 hour, then start buzzing almost like a bad ground. The sub is long out of warranty, and he doesn't...

    Replacement Paradigm Studio 100 V1 woofers? (help)

    Hello all, happy holidays. I noticed a peculiar buzzing noise on upper bass from one of my Paradigm Studio 100's and much to my dismay, found that one of the woofers has a cone misalignment. This is probably due to moving them around more than playing loudly, so I think it's only one woofer...

    Paradigm Studio 100's vs. version 2 and NHT 2.9

    Hey guys, I currently have Paradigm studio 100's and I've been looking around at some other speakers, and wondered if anyone has done a direct comparison between the version 1 and 2? Also, has anyone directly compared the Paradigms to the NHT 2.9? I go to listen to the NHT's in a week or so...

    Tempest Design

    Any thoughts on this design? Single Tempest in a 9.5 cubic foot enclosure tuned to 16.5Hz via a 6" vent ~26.125" long. I'm getting a f3 around 23Hz, shallow rolloff after. Am I missing anything? Also, does anyone have measured parameters for their actual Tempest (I want to see how...

    Tempest PR Design input?

    Hello all, I've cooked up a design using a single Tempest and Dual Pr15 passive radiators that I'd like you all to critique if you could. The box is made of .75" marine-grade plywood and exterior dimensions are 30*20*29 (hwd). Internal volume after bracing and drivers is approx. 8.05cubic...

    Isobaric and Tempest Questions:

    Hello All, I have two questions here. The first concerns the isobaric design; in a push-pull design where the drivers are mounted like this , does the effective sd decrease due to the voice coil taking up moving space on the outside of the box? If so, what would be the expected decrease in...
