    Modelling WinISD _STW-350F188PR01-04 15 inch

    The Peerless spec sheet has good advice on implementation , both sealed and ported. Ported has necessary long ports, in this case , and can have implications re pipe resonances and chuffing. Strongly look into doing sealed, with an amp such as SPA500DSP, Home , or Hypex FusionAmp...

    Small Amplifiers for Floorstanding Speakers

    as always, the details matter - from the TDA 7498 spec sheet , if you look on the lower power graph one is safe @ 0.1 % till circa (real) 70 W (100Hz) which is plenty for the intended application ;)

    How much do cables matter?

    own preferences indeed WHY RICOFFY, FRISCO AND KOFFIEHUIS ARE NOT COFFEE | Daily Sun and Ricoffy, Koffiehuis and Frisco are SA favourites, but are they coffee? In many systems cables actually don't matter (much) , for me the coffee issue is very clear and I am not a Chicory fan :cool:

    Uni-q driver replacements for KEF iq7

    KEF replacement drivers were never cheap , even if you could source some , landed cost would be upward of R4k a piece , (given what is currently available on Ebay). Your loudspeaker is an older model , and going by (some) reviews , probably not KEF's best work. Might explain why the support...

    Interesting video

    remember this applies to a subwoofer - lets say the upper cut off is 80Hz , the wavelength there is 4.5 meter , so the path (length) between your A and B (and phase shift difference) is insignificant, and the sound is omnidirectional. Higher up in Hz totally true as per your pic :) IMHO phase in...

    Interesting video

    raising is not an issue......................decoupling is (y) the opposite can have some benefits, according to some , i.e. adding some weight (on top of / ) to a sub to weigh it down more securely

    Adventures into DIY

    hi Niekz ..................the issue on a desktop & near field that makes it different to regular use , is the exaggerated angles involved, unless you are prepared from the start to tow in the intended speaker sharply , and raise it to ear level , alt tilt it up , it will have poor sound no...

    Adventures into DIY

    There is no need for crossovers if full range drivers are used - sorry sir , this statement is so clearly wrong on all levels that I just needed to respond. At the very least a full range driver needs baffle step compensation on the lower side and very often a notch higher up. Using...

    AR25 crossover replacements

    for the OP doing a comparison between electro - and poly will be a cheap exercise , if he chooses to do , probably worth it to (see) / hear differences. Don't worry if no sonic differences are heard , @jerkyaudio 's comment certainly has value , but isn't always the case IMO . ( note...
