Tymphany TC7FD00-04 2-1/2" Full Range Paper Cone Woofer 4 Ohm
Tymphany TC7FD00-04 2-1/2" Full Range Paper Cone Woofer 4 Ohm is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Ideal replacementGot these for replacements for burnt out JBL SAT125 drivers, they need the mounting holes elongated and the original driver spacer removed to make them fit.

Rated 5 out of 5 by from Very good as a midrange driverUsed this driver in a recent two baffle surface surround speaker build for a friend. They are very clear and crisp. Very similar to Vifa's 3 1/2" 8 ohm driver TC9FD-18-08 which I use in single front baffle speakers. These are matched with Vifa's 4 ohm dome tweeter BC25SC55-04 and a slot loaded down firing GRS 6.5 poly woofer 6PR-8. I am very pleased with all Vifa products purchased to date.

Rated 5 out of 5 by from Rapport qualité/prix épatant !Montés en satellites dans un système 2.1, piloté par un miniDSP 2x4 et filtrés à 150Hz/48dB, ces petits HP font merveille. Peut-être un léger manque d'aigus mais globalement, un son très propre et une faible directivité. Si les large bande de type Fostex ne m'ont jamais convaincu, dans ce diamètre et, surtout, à ce prix le TC7 est un must.

Rated 5 out of 5 by from I have no complaintsI needed a 2.5" speaker to replace my dash speakers in my 3000GT. After trimming the square rim to a circle, they installed fine, and sound equal or better than the factory speakers. I bought some caps to make a hp filter, but they handle full bandwidth signal just fine. Don't have any complaints for a $10 speaker.

How low will it go with internal dimensions of 4"x4"x5.5" and 8x4x3 inch? Also, If with a vent wat is the suggested dimension and its f-response? Since Xmax is not too much, if u recommend vent, will PR help or have to x-over wid sub.

Asked by: arjunm009
In 4x4x5.5 assuming internal dimensions, the recommend box is sealed with an F3 of 160 Hz. In the 8x4x3 the response doesn't change much and goes up to about 170 Hz. I would not recommend going vented with these and a high pass around 150 Hz is necessary if you want a decent amount of output.

What enclosure is recommended for this driver?

The recommended enclosure for this driver is sealed at roughly 0.05 cubic feet. This would be internal dimensions of 4"x4"x5.5".
