| Do subwoofers really help? That all assumes you're not blowing rail fuses, sending the amplifier into thermal shutdown, or getting it to oscillate because it's unstable.Where it's oscillating you want a better amplifier; and otherwise you may be better served with more effi... | |
| Do subwoofers really help? The only place where "amplifier to speaker matching" would really be an issue in the bass would be with something like a single-ended triode with no global feedback and a resulting high output impedance, an OTL amplifier, or Bob Carver's "current ... | |
| Marchand I wrote:>much of which the marchand products won't accomodate. which was incorrect.You can have shelving filters, peaking filters, notch filters, etc. but some one needs to know what you need and calculate component values. Most of that is list... | |
| Marchand The other thing to note here is that #3 is a compromise for the inability to implement affordable speaker level delay networks.People monkey with asymmetries until they get acceptable response over a given vertical window.Ideally, you'd use symmet... | |
| Marchand Note that1) Many cross-overs incorporate compensations for baffle step, rising response with increasing frequency, and driver resonances.2) Many cross-overs combine drivers' acoustic roll-offs with electrical transfer functions to produce the fina... | |
| Floorstander or bookshelf? >I did not make any treatments.The speakers are placed 5ft.(1.5m) away from the side walls and 1.3ft.(0.4m) in front of back walls with 6.5 ft.(2m) distance between them. I find the bass to boomy for my tastes.As expected. You're going to picku... | |
| 2-ways that are close to 3-ways One practical solution is two-ways plus unobtrusively sized sub-woofers, like the Linkwitz Pluto+ system I run in my bedroom including its pair of 14x14x10.75" high sub-woofers. When such woofers are equalized for low frequency extension you need ... | |
| Anyone have comments on radical toe in? I've toed my Linkwitz Orions in to somewhat short of 45 degrees in order to get a wider imaging sweet spot and reduce side-wall reflections/image shift in an asymmetric room with one speaker about 2' from the left wall and the other over 15'.It ma... | |
| Build Your Own? Sure.Linkwitz Orions (believed by many to be the best speaker price no object provided you can live with the output level and placement constraints; and better than his Beethoven Elite in all areas but maximum low frequency output (fixed by the Th... | |
| Room for discussion? >Can you put the speakers on the 155" wall? 125" is a little narrow for my blood.With barely 10' you can't get enough space between speakers + front wall and listener + back wall to avoid unnatural low frequency boosts while still having enough... | |
| Suckout at 40 hertz...less pricey solutions? 1. Play with listener/speaker placement since nulls can cover small spaces. I got rid of the one noticeable suck-out in my current room by moving my seat six inches forwards. Try slightly asymmetric setups - sufficient speaker directivity, side-wa... | |
| Ultimate DIY speaker design? 1. Linkwitz Orion+ (or ++). Believed by many to be the best speaker price no object provided you can live with the placement (really no different than a box speaker, although getting too close to the front wall is worse for bass and side wall less... | |
| Speakons anyone >Do any of you use Speakon connections for your speaker cables.Yup.I switched to 8 pole Speakons with 8-conductor speaker cables in my actively tri-amplified main system. Works great (I did measure for cross-talk and choose an optimal configura... | |
| how far do you sit from your speakers? A little under 7'. The speakers are a little under 7' apart between the tweeters and over 5' off the front wall.I'm over 4' off the back wall although there's an open hallway immediately behind my seat. You want to sit as close as you can with the... | |
| Rules for matching subwoofers to room size >Knownothing >I am setting up a new music listening room and will be adding a subwoofer for movies and (mostly) to fill out the full audio spectrum for music. Is there a rule of thumb for subwoofer size/output for a given room volume? My roo... |
