| Need advice on speaker/x-over update Don't pad the woofer - too many negative side-effects attached to that much series resistance when it wasn't included in the original design work. Once the problem is found all will make sense and the solution will be obvious.Duke | |
| Need advice on speaker/x-over update Measure the original parts and the new ones to be sure they are really the same values; parts can be mislabeled. Double-check the circuit to make sure you have the right parts in the right places; humans are not infallible.Be aware that sometimes ... | |
| Can I get deeper bass from my 890c Boleros? Not knowing any more about the 890c Bolero than what you just posted, I presume they have a passive radiator.Lowering the tuning frequency of a passive radiator will not necessarily give you a "better" bottom end. It will re-shape the speaker's lo... | |
| Speakers to alleviate room anomolies Rleff, in general it's desirable to have a lot of low frequency sources in-room, as long as you aren't stressing the main speakers and as long as you aren't over-emphasizing some portion of the bass region or otherwise creating a problem (like you... | |
| Speakers to alleviate room anomolies Room effects dominate in the bass region, and the peak-and-dip pattern is a function of room dimensions (and damping), source location, and listener location. In other words, move the bass source(s) and/or the listener and you re-arrange the peak-... | |
| Need Guidance: Soundlab A-3 Content Those speakers are very unlikely to be rare/collectible, as the parts, materials, and technology that SoundLab uses has progressed significantly since that pair was made. If the core (the part underneath the cloth) has a wooden frame, and/or cable... | |
| Side firing woofers The electrical phase of the woofer has nothing to do with its physical orientation. The net acoustic phase at the listening position is affected by the relative distance of the drivers from the listener at the crossover frequency. Unless the path ... | |
| Maggies a waste if only 3' from backwall? Most of my experience has been with different planars (as well as with several bipolars), but I don't see much advantage to going with a smaller model instead of a larger one based on distance from the wall. The relevant factor is the path length ... | |
| Room correcting subwoofer for music? There are three reasons why rooms have so much more impact on the sound in the bass region than elsewhere in the room. The first is acoustic, and the second two are psychoacoustic.Normal home listening room dimensions tend to be "small" relative t... | |
| How do you chose speakers based on room size? Saki70, I'd have to see the speaker (and preferably know its crossover frequency) to make a judgment about its radiation pattern.The room gain you get in a small room plays right into the hands of a good back-loaded horn that exits into a corner. ... | |
| New spreakers sound great But Moving either your speakers or listening position (or both) closer to the wall will often increase the perceived bass. For a quick test, go stand up against the wall and see if the bass improves. If that's not feasible, then you might consider add... | |
| Older Altec horn speakers Johnnyb53 wrote: "I prefer a lower crossover point from a 15" speaker, but if it works, it works."He's referring to the 1200 Hz crossover point between the Altec Model 19's 15" woofer and 1" horn-loaded compression driver. At first glance, Johnnyb... | |
| How do you chose speakers based on room size? "What design characteristics would be favorable for speakers in a small room that would not be favorable for speakers that were to be used in a large room and visa/versa?"Well this depends somewhat on where the speakers are located within the room... | |
| How do you chose speakers based on room size? Thanks, Halcro. There can be other reasons for the perceived tonal balance to change with level, but I think differing thermal compression characteristics among drivers is usually the main one. Heykay, even though your 12 by 19 foot room would pro... | |
| How do you chose speakers based on room size? Saki70, you have very good questions. I'm going to avoid getting too specific here because I don't want my post to cross the line and become an "ad". Driver integration is dependent on driver vertical spacing, crossover frequency & slope, and ... |
